MEXICO, Jan 31 2025 (IPS)

This January, Mexico has embarked on a new industrial path for the next six years, where the viability of its energy component faces fundamental challenges that put it at risk.

Energy scarcity is among the main obstacles faced by the economic program of President Claudia Sheinbaum, who has been in office since October.

Researcher Luca Ferrari from the Geosciences Center of the public National Autonomous University of Mexico (UNAM) identified limited financial resources and energy supply as barriers to progress.

“There are budgetary and energy quantity constraints. Increased industrialization for export will run into energy shortages or very limited availability, due to necessary investments and where they will come from. We are in a very precarious energy situation because we are dependent on fossil fuels and are energy deficient,” he told IPS."These are isolated projects that may be interesting. They are a statement of intentions, but should be read in light of other public policy instruments, such as climate and transition, along with the need to align with a comprehensive energy policy": Carlos Asunsolo.

Launched on January 13 under the general title of the National Industrialization and Shared Prosperity Strategy, Plan Mexico (PM) consists of 10 objectives, 13 goals, 2,000 projects, and a total planned investment of US$277 billion, which would create 1.5 million new jobs in manufacturing and other sectors.

Among the plan’s investments, which are seen internally as a partial response to the arrival of ultra-conservative Donald Trump to the U.S. presidency, is an investment by the state-owned Federal Electricity Commissionx (CFE) of US$23.4 billion.

Of this, US$12.3 billion will be allocated to generation, US$7.5 billion to transmission infrastructure, and US$3.6 billion to decentralized photovoltaic production in homes.

Additionally, the government is preparing rules for the private sector’s renewed participation in electricity generation, a modality suspended since 2018 to favor CFE and also the state-owned Mexican Petroleum (Pemex).

This return would include, among other measures, lower energy purchase costs for the electric monopoly and the use of storage batteries to maintain grid stability.

As a result, the plan would add 21,893 megawatts (MW) to the national energy matrix, aiming to reach a 37.8% of clean energy, up from the current 22.5%. By law, CFE controls 54% of the electricity market, with the rest being in private hands.

At least 17 transmission and distribution projects are under study for implementation at an undetermined time, but their development would be independent of the new PM, which does incorporate several projects already underway, as well as new ones.

With a current installed capacity of 89,000 MW, in 2024 approximately 63% of electricity generation depended on fossil gas, followed by conventional thermoelectricity (6.8%), hydroelectricity (5.9%), wind energy (5.8%), solar photovoltaic (5.2%), nuclear (3%), and geothermal (1%).

Renewable sources have an installed capacity of 33,517 MW but only contribute 22.5% of electricity.

In December 2023, during the annual climate summit in Dubai, Mexico joined the Global Commitment on Renewables and Energy Efficiency, which aims to triple alternative installed capacity and double the energy efficiency rate by 2030. Thus, the PM would fall short of the clean generation target.

Gasify, baby, gasify

Since December 2018, when Sheinbaum’s predecessor and mentor left-wing populist Andrés Manuel López Obrador took office as president, Mexico has pursued the so far unattained goal of energy sovereignty, one of whose effects has been the halt of the transition to less polluting fuels.

Sheinbaum’s new package of projects continues this model but also deviates from its extremes, in what seems like the resurrection of the much-needed energy transition, in a strategy marked by apparent contradictions.

For Carlos Asunsolo, manager of Research and Public Policy at the non-governmental Mexican Center for Environmental Law (Cemda), Plan Mexico lacks specific details, such as the pathways to achieve the goals.

“These are isolated projects that may be interesting. It is a statement of intentions, but it should be read in light of other public policy instruments, such as climate and transition, along with the need to align with a comprehensive energy policy,” he analyzed for IPS.

The expert cited concerns about project execution conditions, their type, human rights guarantees, and transparency.

One of the pillars of PM is promoting the relocation (nearshoring) of companies in sectors such as electronics, high technology, and the automotive industry. This is due to the alteration of global maritime transport routes, the repercussions of the Russian invasion of Ukraine in 2022, and the trade dispute between the United States and China.

This section also needs energy and projects progress in the construction of 100 industrial parks, including 12 in the Interoceanic Corridor of the Isthmus of Tehuantepec (CIIT), a megaproject already underway under the responsibility of the Ministry of the Navy.

This corridor in the southeast of the country is one of the three most important legacies of the current government, along with the Maya Train in the southeastern Yucatán Peninsula and the Olmeca refinery in the state of Tabasco, also in the southeast. All three are integrated into the new PM.

The CIIT involves the construction and modernization of three rail routes and three ports between the Pacific coast and the Atlantic Gulf of Mexico.

But these facilities, which seek regional development in the southeast and the substitution of imports from Asia, require lots of energy. Existing and planned renewable generation would not be enough in this area, which would lead Mexico to deepen its dependence on gas imported from the United States.

Since 2010, the northern neighbor has sent more than 18 billion cubic feet (ft3) of gas to Mexico via pipelines. In 2023, Mexico consumed 8.514 billion ft3 daily, of which it imported 6.141 billion from the United States, making it the supplier of 72% of all its gas.

Additionally, the López Obrador administration promoted the Sonora Sustainable Energy Plan, which includes photovoltaic energy, lithium exploitation, and electric vehicle manufacturing in the northern state of Sonora, and which is now incorporated into Sheinbaum’s PM.

One of its components is the Puerto Peñasco photovoltaic plant in Sonora, whose first phase of 120 MW has been operational since 2023. When completed in 2026, it will provide 1,000 MW, with a total investment of $1.6 billion.

For Ferrari, the UNAM researcher, the only possibility for more energy to sustain the business promise is gas.

“We are already in a ridiculously dependent situation. In the United States, production has stabilized over the past year, and it is likely to fall in the coming years. Gas delivery to Mexico is not guaranteed,” he predicted.

Meanwhile, specialist Asunsolo considers it essential to question for whom and for what more energy is being generated, the size of the projects, and the fueling of consumption, at a time when the climate crisis is tightening its grip on very vulnerable places like Mexico.

“There is a clear bet for CFE, through gas, and Pemex, through hydrocarbons, to be the main energy policy. We are only swapping one problem for another with the change of source. If it does not translate into a reduction of hydrocarbons, only generation capacity is increased. There is a confusing message,” emphasized the Cemda expert.

As it progresses, the PM will not only have to face energy obstacles, according to analysts, but will also have to navigate the growing water deficit.

Northern Mexico and parts of the center, south, and southeast were experiencing some degree of drought by January 15, raising questions about water availability for the large projects outlined in the new industrial plan.

Biogas is a champion of sustainability, offering clean, renewable energy and helping to solve the organic waste problem by transforming it into biofuels, says Alex Enrich-Prast, a professor at universities in Brazil and Sweden. Credit: Mario Osava / IPS

RIO DE JANEIRO, Oct 7 2024 (IPS)

“I don’t know of a more sustainable technology for the transformation of society than biogas,” said Professor Alex Enrich-Prast, an activist for this energy alternative with a highly diversified and decentralised expansion in Brazil.

It is not only a renewable and clean energy source, obtained by the anaerobic degradation of organic waste, he argued before entrepreneurs and stakeholders gathered at the 11th national Biogas Forum on 2-3 October in Rio de Janeiro.

Biogas, he added, is also key to the world’s ability to deal with rubbish and waste in general, a problem that punishes humanity, which makes this energy circular.“Biogas follows segmentation by type of substrates. Its business model for sugar cane is different from that of pig farming, dairy cattle, basic sanitation, and other crops”: Cícero Bley Junior.

A researcher on the subject at Brazilian universities and at Linkoping University in Sweden, biologist Enrich-Prast surprised his audience by saying that “biogas, in Brazil, is more relevant for the production of biofertilisers than for energy”.

In Europe, the expansion of this energy source responds to the ‘geopolitical strategy’ of reducing dependence on Russian gas in a continent whose temperatures require heating. The war in Russia-invaded Ukraine uncovered the drama.

In the case of Brazil, a tropical agricultural power, the dependence on imported fertilisers, which account for more than 80% of national consumption, stands out, explained the professor.

As Russia and Ukraine are major suppliers of fertilisers, the war prompted an increase in domestic production, to be partially covered by waste whose biodigestion generates both biogas and an improved manure, rid of gases. The resulting fertiliser, which contains micronutrients, can produce a better fertiliser than chemical ones.

In addition to the geopolitical and economic risks, imported fertilisers are of fossil origin, undermining the low-carbon agriculture that Brazil is trying to promote as part of its climate change mitigation goals.

High cost is the stumbling block

“The difficulty is the cost. Biofertilisers are still more expensive than fossil or mineral fertilisers, and agriculture is not willing to pay that price,” Renata Isfer, president of the Brazilian Biogas and Biomethane Association (Abiogás), the forum’s promoter, told IPS.

Technological advances and the scale of production could reduce costs, but the global market’s environmental demands could lead to a faster path by setting more sustainable and less polluting production, she acknowledged.

In any case, “biogas is vital. There will be no human colonisation on Mars without biogas there,” Enrich-Prast, a professor at the Federal University of Rio de Janeiro currently on loan to his counterpart in São Paulo, told IPS.

In the midst of his teaching, the specialist promotes cooperation between Brazil and Sweden. Together with other researchers, he founded the company Inova Biogás, with the aim of contributing to energy productivity and the quality of biofertilisers.

He values the experience of Europe, where biogas, which when refined becomes biomethane equivalent to natural gas, is now a significant energy input, having explored much of its potential.

In Brazil it is an emerging industry, still lacking in public policies, investments, proprietary technologies and regulations, which is being developed through private, sectoral and experimental initiatives and is designing an expansion through local arrangements, in a territorial decentralisation and by productive ecosystems.

Segmentation

“Biogas follows segmentation by type of substrates. Its business model for sugar cane is different from that of pig farming, dairy cattle, basic sanitation, and other crops,” summarised Cícero Bley Junior, an icon of the sector, currently with his consulting company Bley Energías.

“Everything is biogas, but biogas is only part of the process and the business”, from the activities that generate the substrate or input for biodigestion to the biomethane used in various types of industry, in trucks and other vehicles, he said.

Founder, first president and current president emeritus of Abiogás, Bley drove the biogas movement in southwest Brazil when he was superintendent of renewable energy at Itaipu Binacional (2003-2016), the hydroelectric power plant shared between Brazil and Paraguay on the border between the two countries.

A business model is emerging around the agro-industrial cooperative Primato, in Toledo, a municipality of 150,000 inhabitants in the west of the southern state of Paraná and the country’s largest producer of pork, where Bley currently concentrates his work.

In the transport of animal feed alone, the cooperative has 70 trucks, each of which travels an average of 200 kilometres a day using diesel.

The plan underway to replace fossil fuel with biomethane would result in huge cost savings and a reduction of 89% in greenhouse gas emissions, he said.

Local arrangements are emerging or may emerge all over the country, with an abundance of biomass, from the melon-producing export area in the northeastern state of Alagoas, to another nearby fishing community that grows and consumes cassava, to the heart of the Amazon with many macrophytic aquatic plants, he said.

For the time being, the main production of biogas and biomethane is concentrated in older landfills and in more recent years in sugar cane ethanol plants.

Local production and consumption

One of these, Cocal, in the west of the southern state of São Paulo, supplies part of its biomethane to the gas market in three nearby cities. For this purpose, Necta, which distributes natural gas in most of the state, has built a local pipeline network.

This is also planned to supply a 16-plant ceramics cluster in Santa Gertrudes, another small São Paulo city of 24,000 inhabitants. But this is not the priority of Comgás, the gas distributor in the east of São Paulo state, which includes Santa Gertrudes.

A major problem in the ceramics pole, the city’s air pollution has been reduced by the adoption of natural gas as an energy input, instead of the former use of coal and firewood, according to David Penna, the company’s engineering manager.

The current priority is the replacement of diesel consumption by trucks on the roads with biomethane, which is considered equivalent and does not require technological alterations to vehicles.

Studying the flow of trucks on the roads with statistics is now one of the tasks undertaken by several natural gas distribution companies to identify priority locations for future refuelling stations.

But these are long-term plans, as replacing diesel trucks with gas-powered ones takes time, since these vehicles have a long service life and the automotive industry is slowly increasing production of gas-powered trucks, Penna told IPS during the Biogas Forum.

(Re)energisa, an energy transition company, part of the Energisa electricity generation and distribution group, has also embraced biogas, after concentrating on solar photovoltaics.

It is installing a plant in Campos Novos, in the centre of the southern state of Santa Catarina, Brazil’s largest pork exporter, to generate 25,000 cubic metres of biomethane per day, using waste from the surrounding meat and dairy industry.

It solves the problem of waste from local industry, but the focus is on the production of biofertilisers through composting, according to Roberta Godoi, vice-president of Energy Solutions at (Re)energisa.

CHAPECÓ, Brazil , Apr 29 2024 (IPS)

Biogas sounds like redemption, the conversion of the sinner. Its production involves extracting energy from filth, from the most disgusting environmental pollution, and at the same time avoiding the worsening of the global climate crisis.

The Industrial and Commercial Solid Waste Treatment Center (Cetric) is dedicated to extracting biogas from the waste that abounds in the municipality where it is based, Chapecó, in southern Brazil. “Making use of industrial waste is an important and innovative niche in Brazil, opening up new paths for the emerging biogas market.” -- Heleno Quevedo

With a population of 255,000 and numerous meat processing plants, Chapecó is a main hub in the western part of the state of Santa Catarina, the largest national producer and exporter of pork and also a major poultry producer.

For this reason, biogas production is proliferating in the region, using manure from pig farms, partly due to pressure from environmental authorities to prevent animal waste from continuing to contaminate rivers and soil to the detriment of the environment and human health.

On Apr. 3, the Federation of Santa Catarina Industries launched the Decarbonization Hub program, with the goal of treating 100 percent of swine manure in the next 10 years, among other challenges to meet the agreements to reduce greenhouse gas emissions. It does not seem feasible, but it points in the right direction.

The Cetric group of companies was founded in 2001 with a specific mission: to take care of waste from nearby agribusiness and other smaller sources, from its evaluation and collection to its transportation, processing and disposal.

It then expanded nationally. Today it is active in 12 of Brazil’s 26 states, with four Bioenergy Ecoparks, including the first one in Chapecó, 17 transshipment units with warehouses and 19 emergency teams at strategic points.

“Making use of industrial waste is an important and innovative niche in Brazil, opening up new paths for the emerging biogas market,” said Heleno Quevedo, an energy engineer and creator of the news portal Energía e Biogás, in a telephone interview with IPS from Santo André, a city neighboring São Paulo, also in the south.

Industrial waste as a business

Cetric’s business is the management of waste wherever it is, not just landfills, chemical engineer Loana Defaveri, the company’s technical manager, told IPS. Guidance on the handling of this material in industries is part of their activity.

The company also acts in emergencies, such as accidents with dangerous loads on highways, cities or production sites. It is a kind of firefighter in these cases and deploys specialized personnel with the necessary tools and vehicles for prompt assistance, dispersed throughout 19 locations in the country.

In mid-April, a team dealt with a spill of propionic acid, used to preserve food, when a truck overturned in Paraná, a neighboring state. The most frequent are accidents involving trucks carrying fuel such as ethanol and diesel, Defaveri said at the company’s facilities.

A Command Center, a rotating team of four people, monitors by video the fleet of more than 200 Cetric trucks 24 hours a day from the company’s headquarters and the emergencies addressed.

But the ecopark in Chapecó is the heart, the center of innovations and the circular economy of the Cetric Group, which is involved in a range of activities.

Bioenergy production began in 2005, but was suspended due to the scarcity and low durability of biogas equipment. It resumed 15 years later and now has five covered lagoon biodigesters and a continuous stirred tank reactor, known as CSTR.

Only organic material is used for this purpose. The waste collected by the company is class 1, hazardous waste, generally chemical, and class 2, which includes inert waste such as iron scrap or concrete, and waste that degrades, such as organic waste, which is the bioenergy part.

Biogas from landfills and biodigesters

From the large landfill covered with impermeable black tarpaulin, which accumulates most of the garbage, biogas is extracted that only serves to generate heat, because it contains little methane, Defaveri explained. Burning this biogas reduced 80 percent of the firewood previously consumed in the ecopark.

For electricity generation and the refining that converts it into biomethane, the biogas that comes out of the biodigesters, which has 71 percent methane, and the reactor, with 73 percent, is used, she said.

In this energy sector, four biogas generators produce one megawatt of power, electricity estimated to be sufficient for the company’s consumption.

Another part of the biogas is refined by membranes, activated carbon and other processes to remove carbon dioxide (CO2) and sulfuric acid (H2S) to obtain biomethane, which is the fuel used by a 100 percent gas truck and 15 other hybrid trucks that consume gas and diesel.

Another 28 trucks recently acquired in Chapecó will also use 100 percent biomethane or natural gas as fuel, as the two gases are equivalent.

Productivity still low

But production is still not very efficient, despite the progress represented by the CSTR reactor. “We only produce 10 percent of our biogas potential, but we are increasing productivity with technological advances, new investments and personnel training,” Defaveri noted.

Cetric Chapecó currently produces 250 cubic meters of methane per hour and intends to reach 1,500 cubic meters per hour, i.e. six times the volume, which requires heavy investment and also depends on the substrate, as they call the input, she said.

The effluent resulting from this process undergoes a complex treatment, which includes waste separation, sand filters, membranes, electrolysis and even a reverse osmosis device.

This makes it possible to obtain water of sufficient quality for reuse in washing vehicles and other equipment, chemical engineer Diego Molinet told IPS. The solid part goes to composting for processing that can result in biofertilizer.

The effluent cannot be used as fertilizer, a common practice among small biogas producers such as pig farmers, because it can saturate the soil, with an excess of some components, such as phosphorous, said Molinet.

Diego Molinet, a chemical engineer at Cetric, holds in his hands the result of the treatment of effluents from the industrial waste treatment process, with production of biogas and biomethane: a glass with clean water for non-potable reuse and another glass with solid material that can be converted into fertilizer after composting.

Effluent treatment also produces ARLA 32, a pure urea compound that is mandatory in heavy vehicle exhaust to reduce the emission of pollutant gases, such as nitrogen oxide. It is of growing use in the automotive industry.

“Cetric enjoys a good reputation” and plays an important role in Chapecó by preventing the city from having to send its industrial waste to other municipalities, Marck Gehlen, the city government director of the environment, told IPS.

Its emergency service has already controlled several accidents in the city. One was a fire at a fuel distribution company, whose rapid control prevented contamination of water courses and risks to the population, said Gehlen, an environmental engineer who has worked in the sector for more than 10 years, three years as director.

One concern is the sometimes dangerous truckloads of industrial waste that crisscross the city, he admitted.

With four meatpacking plants on the periphery of the city, Chapecó has had some problems, such as the stench emitted by the plants, although that was brought under control years ago. In general, the companies have adopted measures to avoid environmental damage and one of them has already transferred potentially polluting activities away from the city.

LA PAZ, Mexico , Feb 19 2024 (IPS)

The specter of blackouts hovers over the Mexican city of La Paz, the capital of the state of Baja California Sur in Mexico’s far northwestern corner, as summer approaches, due to increased electricity demand from air conditioning and insufficient capacity in the local grid.

Since 2019, the local population has suffered the effects of this situation when it starts to heat up in June in this city located 1680 kilometers from Mexico City, which has the additional difficulty of being located in the south of a peninsula that it shares with the state of Baja California."The location of renewables rarely follows criteria where they are most needed, because the idea is to feed the centralized system. The more rural sectors or those far from cities are not connected to the grid; progress in those areas is slow." -- Gabriela Cabaña

Being separated from the national power grid, due to its distance, Baja California Sur is an energy island whose energy mix depends on thermoelectric plants that burn fuel oil, a very dirty fuel, diesel and gas, while renewable energy contributes about 10 percent. La Paz is where most of the energy is generated, although the highest level of consumption is in the neighboring municipality of Los Cabos, due to its urban growth and insufficient production.

Lucía Frausto, executive director of the non-governmental organization Cómo vamos La Paz, said the model reflects inequities in this city, which had a population of 292,241 according to the last census in 2020.

“The high costs leave no benefits to the community and that impacts everyone. There are sectors that use a lot of energy and others that barely have any. When there are blackouts the water can’t be pumped. It also affects the productivity and competitiveness of businesses,” she told IPS.

The evidence indicates that renewable energy, which is needed to reduce the polluting emissions that overheat the planet, does not address inequality and in some cases foments it.

For this reason, non-governmental organizations and academic groups in Latin America and around the world are pushing for a just transition, understood as an inclusive process, above and beyond mere technological substitution and in line with respect for human rights.

Energy inequality is not just seen in Mexico but extends throughout the Latin American region.

In Latin America and the Caribbean there has been progress in renewable energy, although its impact on inequality is still invisible in the least equitable region on the planet. In addition, almost the entire population has access to electricity, but challenges remain, such as clean energy for cooking and energy efficiency.

The report Fostering Effective Energy Transition 2023, released by the World Economic Forum (WEF), which brings together governments, companies and civil society organizations, warns that the energy transition in Mexico presents a tendency to strengthen inequality.

In this Latin American country, where the energy transition is not moving forward, 15 percent of the population of 129 million lacks access to clean fuel sources in the kitchen and energy efficiency stands at 3.2 percent, below the world average of 4.6 percent. This is part of the persistence of energy inequality, even though poverty fell between 2016 and 2022.

This is reported by the Tracking SDG7: The Energy Progress Report 2023, drawn up by the International Energy Agency, the International Renewable Energy Agency, the United Nations Statistics Division, the World Bank and the World Health Organization.

Population growth in the city of La Paz, capital of the northwestern peninsular Mexican state of Baja California Sur, is also driving the increase in electricity demand in a territory whose supply network is isolated from the national grid and is falling increasingly short. The city is an example of the inequality in access to energy, and especially to alternative sources, in the Latin American region. CREDIT: Emilio Godoy / IPS

Poorly distributed?

Latin America and the Caribbean, a region with 662 million inhabitants, 29 percent of whom live in poverty, have the largest proportion of modern renewable energy use, thanks to hydropower, bioenergy and biofuels.

According to Gabriela Cabaña, a researcher at the non-governmental Center for Socio-environmental Analysis, in most Latin American countries renewable energy is not installed in areas with economic and energy needs, but rather they are in areas privileged by the power grid.

“The location of renewables rarely follows criteria where they are most needed, because the idea is to feed the centralized system. The more rural sectors or those far from cities are not connected to the grid; progress in those areas is slow,” she told IPS from the island of Chiloé, in southern Chile.

In her view, this is a generalized phenomenon in Latin America, where local communities receive the impacts but not necessarily the benefits.

In Chile, the transition shows progress, but there are risks in terms of equity, says the WEF. In that nation, energy efficiency stands at 3.6 percent.

The WEF report says the transition to less polluting forms of energy in Argentina is stable in terms of equity, but local environmental organizations have suffered a major setback under the government of far-right President Javier Milei, in office since Dec. 10.

Moreover, the South American nation reports ups and downs on its path to a low-carbon energy system, and energy efficiency of 3.5 percent.

On the other hand, the transition is inequitable in Brazil, the WEF concludes. In the largest economy and most populous country in the region, with 203 million inhabitants, three percent of the population uses dirty cookstoves, and energy efficiency stands at four percent.

Back in La Paz, Alfredo Bermudez, a researcher at the Department of Fisheries Engineering of the public Autonomous University of Baja California Sur, said the energy scheme in the city has inherited environmental, economic and social consequences.

“La Paz bears the costs and the benefits are not compensated, they are not proportional. There is differential treatment” that is unfair, he told IPS.

Due to local grid congestion, the state can only interconnect 28 megawatts (Mw) and there will be more space perhaps in 2026, which poses obstacles to decentralized solar deployment and illegal connections to the grid.

Official figures indicate that in Mexico there are 367,207 distributed generation permits for 2,954 Mw, figures that have been growing since 2007. In the first half of 2023, 32,223 permits were approved, half of the total for 2022. But Baja California Sur only has 1634 authorizations for 23 Mw, one of the lowest rates in the country.

The electrified poor

While a minority can finance the installation of solar panels on their homes or drive an electric vehicle, the majority rely on dirty energy or polluting transport.

This gap poses a risk to the fulfillment of the seventh of the 17 Sustainable Development Goals (SDGs), which promotes affordable, clean energy. One of its targets is to “ensure access to affordable, secure, sustainable and modern energy for all,” as part of the 2030 Agenda, adopted in 2015 by the United Nations member states.

In Mexico, the region’s second largest economy, the poorest areas lack renewable energy installations or do not benefit directly from such infrastructure. For example, the southern state of Chiapas, one of the most impoverished in the country, which relies on hydroelectric plants, has only one private wind farm, producing 49 Mw of power. Guerrero, a poor state in the southwest, has no wind farms.

And while Oaxaca, another poor southern state, has the largest installed wind capacity in the country, there are meager benefits for local communities. Oaxaca and Chiapas are among the territories with the fewest distributed generation connections.

In Brazil, Pernambuco in the northeast was the fourth poorest state in 2021 and is one of the largest generators of solar energy, but neither solar nor wind power benefit the population of this and other disadvantaged territories in the country, which in 2023 reached a new record for solar power generation.

In Argentina, population 46 million, the province of Buenos Aires, where the capital is located, has the second largest number of wind turbines, but at the same time has one of the highest poverty rates in the country. A similar phenomenon occurs in the case of solar energy.

In Chile, a country of 19.5 million people, the northern region of Atacama ranks third in solar generation and is a leading wind energy producer in the country, but it also has the second highest poverty rate. .

Improvements

By encouraging the use of computers and the Internet, promoting cleaner forms of cooking and heating or cooling, cleaner energy generates a host of benefits that can have an impact on reducing inequality.

Frausto the activist and Bermudez the academic proposed a greater deployment of renewables and decentralization of generation in Baja California Sur and other energy vulnerable states.

“We need to diversify production and distribution, to have generation throughout the country,” the activist said.

Meanwhile, Bermudez sees an opportunity in the high costs. “You can try things that are not possible in other places, because of the particularities of the state. Anything that reduces costs is advantageous” in electricity generation and efficiency, he said.

Cabaña from Chile recommended public investment to replace private fossil fuel infrastructure.

“We should consider that energy infrastructure should not be in pursuit of a centralized model, but should focus on something more community-based. A change is needed to help combat energy poverty,” she argued.

Jorge Sarmientos said he made a good investment when he bought an electric motorcycle to get around and avoid the anxiety suffered by the users of Cuba’s deficient public transportation system or the high prices of private alternatives.

“It was expensive, but I gained independence,” Sarmientos, a Havana-based accountant, told IPS. “Transportation has never been good here. When there is no shortage of buses, there are shortages of spare parts or fuel. Prices should be lowered or there should be facilities for more people to acquire electric vehicles.”"Transportation has never been good here.

Over the last decade, the use of electric vehicles has increased in Cuba, based on customs authorizations for their importation.

More recently, the domestic industry has begun to assemble different models, including electric bicycles and three-wheelers, using parts imported largely from China.

But the fact that they are mainly sold in foreign currency is a hurdle to expanding sales.

The cheapest models in state-owned stores exceed 1,000 dollars, while others go for as much as 6,000 dollars.

In Cuba, the average monthly salary is equivalent to about 35 dollars according to the official exchange rate, or about 16 dollars in the informal market.

According to reports, almost 40 hybrid buses (alternating diesel and electricity) have been added to Havana’s deteriorated fleet of public buses in recent years, a technology that saves 25 to 30 percent of fuel and is less polluting.

But the severe internal economic crisis and the shortage of foreign currency are hindering actions to increase the number of 100 percent electric vehicles in order to gradually decarbonize public transportation.

Some companies and institutions have acquired electric cars, which bring reductions in maintenance costs.

Local solutions

In the case of Havana, from 2019 to 2023 the Neomovilidad project was implemented, which among its objectives aimed to strengthen the regulatory framework for an efficient transition to a low-emission urban transportation system.

In addition to prioritizing variables such as a gender approach and the inclusion of different age groups, the project provided a pilot public bicycle rental station, run by a local development project led by young people.

It also created three routes of three-wheeled electric ecotaxis driven mainly by women in outlying neighborhoods of Boyeros, one of the 15 municipalities that make up Havana.

The three-wheelers are light, motorized vehicles with a capacity for six passengers in the back, similar to the autorickshaws or tuktuks that are common in Asia. Here they are also called motocarros or mototaxis.

“I think they are a great option for getting around quickly over short distances, and at affordable prices,” retiree Gloria Almaguer, a resident of the Fontanar neighborhood in Boyeros, told IPS. “The bad thing is that there are not enough to cover demand, they can carry only a few people, and there are certain times of day when they ‘vanish’.”

The Neomovilidad project was executed by Havana’s General Directorate of Transportation, implemented by the United Nations Development Program (UNDP) office in Cuba and financed by the Global Environment Facility (GEF).

Other fleets of ecotaxis provide service in the capital’s municipalities of Old Havana, Central Havana, Guanabacoa, Playa and Plaza de la Revolución, also with UNDP support. These are all initiatives that contribute to the national commitment to mitigate climate change.

With routes ranging from two to four kilometers and low prices, a little more than a hundred of these vehicles help provide a solution for sustainable micro-mobility in urban areas.

In other Cuban cities, similar three wheelers with internal combustion engines are in service.

One challenge is that the vast majority of ecotaxis and electric vehicles depend on the national electric grid to recharge their batteries. The ecotaxis recharge during the night at their terminals in the parking lots of public entities, and privately owned vehicles do so at their owners’ homes.

This is because so far there is no infrastructure that would allow electric vehicles to be recharged in a network of service stations.

Around 95 percent of Cuba’s electricity generation relies on fossil fuels.

The government considers it a matter of national security to transform the energy mix, and aims for more than 30 percent of electricity to come from clean energies by 2030, a goal that will be difficult to achieve due to the need for a high level of investment.

New fuel prices

A majority of the Cuban population depends on the public transportation system, based mainly on buses and other fossil fuel-consuming vehicles.

In Havana, home to 2.1 million inhabitants, “less than 300 buses are working, a city that in the 1980s had 2,500 buses and only four years ago had 600,” said Transport Minister Eduardo Rodríguez Dávila during a television appearance in October 2023.

The greatest impact falls on those with the lowest purchasing power, since buses are the most affordable means of transportation.

The panorama is similar in Cuba’s other 14 provinces. Alternative transport in urban, suburban and rural settlements includes modified trucks, traditional horse-drawn carriages and bicycle cabs which carry one or two passengers and are pedaled by the driver.

In Havana, estimates place the total number of passengers who use private transport at around 25 percent, generally in old U.S.-made cars, the so-called “almendrones” – private cabs with fixed routes – which run on gasoline or diesel and are not affordable for everyone.

Together with the deterioration of the vehicle fleet, the chronic shortage of spare parts, lubricants and other supplies, and the migration of drivers to sectors with greater economic benefits, the fuel shortage has been one of the main causes of the irregular public transportation service, which has been accentuated in the last five years.

“You can spend an hour waiting, or more. A lot of times I’m late for class, even though I get up very early. I can’t afford a private car every day. It’s increasingly difficult to get anywhere,” stressed architecture student Yenia Hernández in an interview with IPS, as she waited at a bus stop with dozens of other people in the Central Havana municipality.

Energy crises have become more recurrent since 2019, in parallel with the decline of the domestic economic situation and the lack of foreign currency.

According to the authorities, this situation has multiple causes, from breach of contract by suppliers to U.S. government sanctions that hinder access to credit and services from international banks.

In 2021 Cuba imported 126,000 tons of gasoline, in 2022 some 192,000 tons, and in 2023 around 203,000 tons. Despite the increase, the figure remains below the demand of about 360,000 tons, Energy and Mines Minister Vicente de la O Levy said in a televised statement on Jan. 8.

On the other hand, this island nation needs 1.8 billion dollars to cover its annual diesel needs.

“In 2023, 609,000 tons of diesel could be imported, for about 600 million dollars (one third),” added the Energy and Mines Minister.

As of Feb. 1, an increase in the price of gasoline and diesel was planned, in order to bring the selling price in Cuban pesos in line with the official rate of the dollar, regulate sales and sell a portion only through dollar-backed cards, in order to guarantee resupply with the foreign currency, according to the government.

But the measure was postponed until further notice due to a “cybersecurity incident” caused by “a virus from abroad” that affected the system of fuel sales, which is being investigated, official information said.

The strategy to eliminate subsidies projects, as of Mar. 1, an increase in interprovincial transportation fares, with hikes of almost three times the cost of bus fares and six to seven times the cost of train tickets.

While the fares for part of the public transport service will remain unchanged, in the case of Havana, the fare for electric three wheelers will rise from four to 10 pesos (0.03 to 0.08 dollars).

The increases in fuel prices and transportation fares are in addition to the package of provisions that includes tax and tariff modifications as of Jan. 1 and which, according to government officials, are aimed at “rectifying distortions” in the economy and boosting its recovery.

“The only thing I see is that some transportation will be more expensive, but there won’t necessarily be more vehicles, or more modern vehicles with better service,” Reynaldo Martín, an electrical engineer living in Old Havana, told IPS. “Wages remain the same and that means I can’t even dream of buying a bicycle.”

The installation of photovoltaic panels to use solar energy to irrigate small farms is expanding quickly in Chile because it lowers costs and optimizes the use of scarce water resources.

This long, narrow South American country that stretches from the northern Atacama Desert to the southern Patagonia region and from the Andes Mountains to the Pacific Ocean is extremely rich in renewable energies, especially solar and wind power."Solar panels have made an immensely important contribution to our energy expenditure. Without them we would consume a lot of electricity." -- Myriam Miller

Last year, 36.6 percent of Chile’s electricity mix was made up of Non-Conventional Renewable Energies (NCREs), whose generation in May 2023 totaled 2392 gigawatt hours (GWh), including 1190 GWh of solar power.

This boom in the development of alternative energies has been mainly led by large companies that have installed solar panels throughout the country, including the desert. The phenomenon has also reached small farmers throughout this South American country who use solar energy.

In family farming, solar energy converted into electricity is installed with the help of resources from the government’s Agricultural Development Institute (Indap), which promotes sustainable production of healthy food among small farmers, incorporating new irrigation techniques.

In 2020 alone, the last year for which the institute provides data, Indap promoted 206 new irrigation projects that incorporated NCREs with an investment of more than 2.1 million dollars.

That year, of the projects financed and implemented, 182 formed part of the Intra-predial Irrigation Program, 17 of the Minor Works Irrigation Program and seven of the Associative Irrigation Program. The investment includes solar panels for irrigation systems.

Within this framework, 2025 photovoltaic panels with an installed capacity of 668 kilowatts were installed, producing 1002 megawatt hours and preventing the emission of 234 tons of carbon dioxide.

The six solar panels installed on the small farm of Myriam Miller and Freddy Vargas, in the municipality of Mostazal, south of Santiago, Chile, allow them to pump water to their three greenhouses with thousands of tomato plants and to their vegetable garden. They also drastically reduced their electric energy expenditure. CREDIT: Orlando Milesi / IPS

An experience in Mostazal

“Solar panels have made an immensely important contribution to our energy expenditure. Without them we would consume a lot of electricity,” 50-year-old farmer Myriam Miller told IPS at her farm in the municipality of Mostazal, 66 km south of Santiago, where some 54,000 people live in different communities.

Miller has half a hectare of land, with a small portion set aside for three greenhouses with nearly 1,500 tomato plants. Other tomato plants grow in rows outdoors, including heirloom varieties whose seeds she works to preserve, such as oxheart and pink tomatoes.

Indap provided 7780 dollars in financing to install the solar panels on her land. Meanwhile, she and her husband, Freddy Vargas, 51, who run their farm together, contributed 10 percent of the total cost.

In 2023, Miller and Vargas built a third greenhouse to increase their production, which they sell on their own land.

“We’re producing around 8,000 kilos of tomatoes per season. This year we will exceed that goal. We’re happy because we’re moving ahead little by little and improving our production year,” Miller said as she picked tomatoes.

On the land next to the tomato plants, the couple grows vegetables, mainly lettuce, some 7,000 heads a year. They also have fruit trees.

Vargas told IPS that they needed electricity to irrigate the greenhouses because “it’s not easy to do it by hand.”

The farm has two wells that hold about 30,000 liters of water that arrives once a week from a dam located two kilometers away. This is the water they use to power the pumps to irrigate the greenhouses.

“We have water rights and Indap provided us with solar panels and tools to automate irrigation. They gave us four panels and we made an additional investment, with our own funds, and installed six,” Vargas explained.

The couple consumes between 250 and 300 kilowatts per month and the surplus energy they generate is injected into the household grid.

“We don’t have storage batteries, which are more expensive. Every month the electric company sends us a bill detailing the total we have injected into the grid and what we have consumed. They calculate it and we pay the difference,” Vargas said.

The average savings in the cost of consumption is 80 percent.

“I haven’t paid anything in the (southern hemisphere) summer for years. In the winter I spend 30,000 to 40,000 pesos (between 33 and 44 dollars) but I only pay between 5,000 and 10,000 pesos a month (5.5 to 11 dollars) thanks to the energy I generate,” the farmer said.

Above and beyond the savings, Miller stressed the “personal growth and social contribution we make with our products that go to households that need healthier food. We feel good about contributing to the environment.”

“We have a network, still small, of agroecological producers. There is a lack of information among the public about what people eat,” she added.

Their tomatoes are highly prized. “People come to buy them because of their flavor and because they are very juicy. Once people taste them, they come back and recommend them by word of mouth,” Miller said.

She is optimistic and believes that in the municipalities of Mostazal and nearby Codegua, young people are more and more interested in contributing to the planet, producing their own food and selling the surplus.

“We just need a little support and more interest in youth projects in agriculture to raise awareness that just as we take care of the land, it also gives to us,” she said.

A pesticide-free new generation

Valentina Martínez, 32, is an environmental engineer. Together with her father, Simón, 75, they work as small farmers in the municipality of María Pinto, 60 kilometers north of Santiago. She has a 0.45 hectare plot and her father has a 0.35 hectare plot.

Both have just obtained funding from the Transition to Sustainable Agriculture (TAS) project, which operates within Indap, and they are excited about production without chemical fertilizers and are trying to meet the goal of securing another larger loan that would enable them to build a greenhouse and expand fruit and vegetable production on the two farms.

“It’s a two-year program. In the first year you apply and they give you an incentive of 450,000 pesos (500 dollars) focused on buying technology. I’ve invested in plants, fruit trees, worms, and containers for making preserves,” Valentina told IPS.

In the second year, depending on the results of the first year, they will apply for a fund of 3900 dollars for each plot, to invest in their production.

“This year my father and I will apply for solar panels to improve irrigation,” said Valentina, who is currently dedicated to producing seedlings.

“My father liked the idea of producing without agrochemicals to combat pests,” she said about Simón, who has a fruit tree orchard and also grows vegetables.

In María Pinto there are 380 small farmers on the census, but the real number is estimated at about 500. Another 300 are medium-sized farmers.

The rest of the area is monopolized by large agricultural companies dedicated to monocultures for export. Most of them have citrus, avocado, cherry and peach trees, as well as some walnut trees, and they all make intensive use of chemical fertilizers.

Chile exports mainly copper, followed by iron. But it also stands out for its sales of fish, cellulose pulp and fruit. In 2023, it exported 2.3 million tons of fruit, produced by large farms and bringing in 5.04 billion dollars. Agriculture represents 4.3 percent of the country’s GDP.

Family farming consists of some 260,000 small farms, which account for 98 percent of the country’s farms, according to the government’s Office of Agrarian Studies and Policies (Odepa).

Family farms produce 40 percent of annual crops and 22 percent of total agricultural production, which is key to feeding the country’s 19.7 million people.

Valentina is excited about TAS and the meetings she has had with other young farmers.

“It’s fun. We’re all on the same page and interested in what each other is doing. We start in December and January and it lasts all year. The young people are learning about sustainable agriculture and that there are more projects to apply for,” she explained.

She said that 15 young people in María Pinto have projects with pistachio trees, fruit trees, greenhouse gardens, outdoor gardens, animal husbandry and orchards. They are all different and receive group and individual training.

The training is provided by Indap and the Local Development Program (Prodesal), its regional representatives and the Foundation for the Promotion and Development of Women (Prodemu).

“The idea is that more people can learn about and realize the benefits of sustainable agriculture for their own health and for their land, which in a few years will be impossible due to the spraying of monocultures,” Valentina said.

It targets large entrepreneurs who produce avocado and broccoli in up to four harvests a year, both water-intensive crops, even on high hillsides.

“We need to come together, do things properly and recruit more people to create a legal group to reach other places and be able to organize projects. When you exist as an organization, you can also reach other places and say I am no longer one person, we are 15, we are 20, 100 and we need this,” she said.

CARACAS, Mar 21 2023 (IPS)

The installation of solar panels in a remote village in ​​the Andes highlands in late February marked a second incursion by the Venezuelan government into the field of solar energy, previously uncharted territory in this country that for a century was a leading global oil producer.

The governor of the Andean state of Mérida, Jehyson Guzmán, inaugurated the 135 solar panels that will initially serve 17 families in the El Anís village near the town of Lagunillas, 600 kilometers southwest of Caracas, and will later provide electricity to a total of 2,500 people, in neighboring communities as well.

“They’re presenting it as something new, but they probably brought materials from a facility they had in the area around PDVSA (the state-owned oil company), where an industrial-scale project failed and was abandoned,” alternative energy expert Alejandro López-González told IPS."Compared to an average cost of 0.20 dollars per kilowatt-hour in other Latin American countries, in Venezuela people pay 0.002 dollars….and a cultural issue is that Venezuelans are not used to saving energy and many people, between 30 and 40 percent of users, simply do not pay for electricity." -- Luis Ramírez

López-González also pointed out that the government program “Sembrando Luz”, developed by Venezuelan and Cuban engineers, installed close to 2,300 small solar power systems, mainly in rural and indigenous communities, between 2005 and 2012.

Venezuela was then governed by the late Hugo Chávez (1999-2013). During his time in office the country went through a cycle of oil wealth, followed by the collapse of the oil industry and numerous infrastructure and service projects, such as alternative electricity, most of which were abandoned half-complete.

There are also wind farms on the peninsulas of Paraguaná and Guajira, in the northwest – where the trade winds are constant, strong and fast – and adding more than 100 wind turbines could contribute up to 150 Mwh to the local grid in one of the areas hardest-hit by blackouts so far this century.

Wind turbines began to be installed starting in 2006 in Paraguaná and 2011 in La Guajira, and more than 400 million dollars were invested, with the idea of ​​supplying numerous indigenous communities mainly of the Wayúu people.

But the installation of more wind turbines and equipment was delayed, the project fell by the wayside, many materials were stolen to be sold as scrap, and by 2018 the then minister of electric power, Luis Motta, gave it up for lost.

A similar fate befell hundreds of small solar energy projects – in some cases accompanied by wind power – in peasant and indigenous communities, which would have “benefited up to 200,000 people throughout the country but were put out of service due to lack of maintenance and attention,” lamented López-González.

Actually, before “Sembrando luz”, there were specific and especially rural initiatives for solar and wind energy – for example, to dig water wells in the plains of the Orinoco – organized by individuals, universities and some public entities.

The universities’ turn

Now the initiatives are reaching urban areas, among individuals in cities hard-hit by long power cuts, such as the hot city of Maracaibo in the northwest, the country’s oil capital, commercial establishments, health centers, and an exemplary installation in the private Andrés Bello Catholic University (UCAB), in Caracas.

UCAB “decided to incorporate ecology and sustainability into programs, practices, the management of its 32-hectare campus where there are some 5,000 students in various disciplines, as an experiment and contribution to environmental science in the country,” Joaquín Benítez, director of Environmental Sustainability, told IPS.

Thus, since 2019, the roof of the postgraduate studies building has been transformed into a green roof, with an 800-square-meter garden of low-lying succulent plants that store water.

Several classrooms under that roof, where temperatures at 3:00 p.m. local time reached 31 degrees Celsius for most of the year in 2013, now have an average temperature of 25 degrees, Benítez said.

The garden was followed by the installation of 30 solar panels along the edge of the roof, plus a backup wind generator, to support research and study projects, provide energy to part of the building and feed the watering device for the plants.

Enough energy is generated to serve a house for five people, with three bedrooms on two floors, two bathrooms and a small garden, Benítez said.

Learning from failures

But a panel installation in a home, farm or small business, even if it is only complementary to the national electrical grid or used to power only a few appliances, costs from 4,000 dollars up to five times that amount. This is a huge sum in a country where the majority of the population is living in poverty and the monthly minimum wage is less than six dollars.

However, hundreds of private solar power installations have sprung up, often in combination with diesel-fired plants – and also small wind turbines – in areas of the west and the central and eastern plains, with a handful of companies dedicated to installation and maintenance.

The electricity crisis has been part of an economic depression and social and political crisis that has pushed more than seven million Venezuelans to leave the country in the last decade under President Nicolás Maduro, reducing the population to an estimated 28 million inhabitants.

The northwestern oil and ranching state of Zulia alone, covering 63,000 square kilometers and home to five million people, suffered 37,000 power failures last year, according to the Committee of People Affected by Blackouts.

Outages across the country totaled 233,000 last year and 196,000 in 2021. Four years ago, in March 2019, a blackout left almost all of Venezuela, including much of Caracas, without power for between 72 and 100 continuous hours.

The country is supplied by the Guri hydroelectric complex in the southeast, with an installed capacity of 12,000 Mwh in three dams, and which covers two thirds of the national demand. Another 30 percent comes from thermal plants, and the rest from small distributed generation plants.

In total, the country’s installed capacity, which should have reached 34,000 Mwh according to the investments made over decades, barely reaches 24,000 Mwh, since much of the infrastructure is rundown, as are the distribution networks.

The supply deficit would be even worse were it not for the collapse of the economy, as the country’s GDP plunged by up to 80 percent between 2013 and 2021, and demand, which stood at around 19,000 Mwh in 2013, had dropped to 11,000 Mwh in 2019.

Paying little or nothing

Renewable energy expert Luis Ramírez reminded IPS that electricity in Venezuela, in the hands of the State, is subsidized up to 99 percent.

“Compared to an average cost of 0.20 dollars per kilowatt-hour in other Latin American countries, in Venezuela people pay 0.002 dollars,” said Ramírez, who is also director of the graduate program in quality systems at UCAB.

However, since 2022 the rates for public services, such as water, electricity, cooking gas, gasoline, highway use and garbage collection have begun to rise in different regions of the country.

In addition, “a cultural issue is that Venezuelans are not used to saving energy and many people, between 30 and 40 percent of users, simply do not pay for electricity,” Ramírez explained.

The inhabitants of poor neighborhoods and shantytowns in Caracas and other cities connect themselves to the grid freely, and in small towns in the interior small business establishments often do the same.

This discourages investments in the sector and in particular in renewable energies, which often have higher installation and start-up costs than plants powered by fossil energy.

Pending policies, laws, initiatives and financing to establish solar or wind farms, hydroelectric power generated in the gigantic complex of Lake Guri, which feeds the Caroní River in the southeast of the country, remains the source that sustains two thirds of electricity consumption in Venezuela.

From law to potential

Publications from the Ministry of Electric Power indicate that an additional 500 Mwh are expected to be installed in the west of the country, mainly from renewable energies, but without specifying a timeframe, amounts to be invested or sources of financing.

In the legislature, controlled by the ruling United Socialist Party of Venezuela, the drafting of a renewable energy law was proposed since 2021, to stimulate and organize the sector, but the question has not been given priority by parliament or the government.

The experts consulted by IPS agree that the drafts of that law mainly repeat provisions already present in the current Organic Law on Electricity Service, without adding new aspects such as establishing a renewable energy research institute to help develop the industry, Ramírez said.

According to López-González, the fact that the electricity law enacted in 2010 still lacks regulations to specify policies in measures and technical and operational decisions shows the State’s disdain for ensuring compliance and promoting the development of the sector.

He said the new steps such as the small installation in the Andes and the announcements that a new law is being prepared are “an effort to publicize what is nothing more than a residual development, no more than zombies of abandoned projects.”

Venezuela’s solar potential is one of the highest in Latin America, with an average of 5.35 kilowatt hours per square meter per day (5.35 Kwh/m2), close to the highest in Chile (5.75) and Bolivia (5.42), according to studies by the Department of Sciences of the Universitiy de Los Andes, in the southwest of the country.

In the northern coastal region along the Caribbean Sea, the information collected in meteorological stations shows an even greater potential: between 5.8 and 7.3 Kwh/m2.

In the north, where the most populated and industrialized centers of the country are located, the potential of 12,000 Mwh awaits better times, López-González said. “We can have a wind Guri,” he said, making a comparison with the largest of the dams in the southeastern hydroelectric complex.

Venezuela, a leading oil producer for a century, which still has the largest reserves in the world (300 billion barrels, mostly unconventional), also has the potential to belong to the club of countries that are self-sufficient in renewable energy.

But this membership is still just a spot on the distant horizon.

DÜSSELDORF, Germany, Aug 1 2016 (IPS)

Germany has been undergoing an energy transition for over 20 years, and it can offer valuable lessons to Latin America with regard to promoting renewable energy and moving towards a low-carbon economy.

Germany’s transformation formally began in 2011, based on six laws that foment alternative energies through a surcharge for suppliers, the expansion of the power grid to boost the incorporation of renewables, and cogeneration, to use energy that goes to waste in power plants that run on fossil fuels.

There are twice as many laws that bolster the generation and consumption of renewable sources worldwide as there were at the start of the century, and Latin America is no exception to this trend.

“Other countries, including those of Latin America, should probably look at Germany’s experiences and learn from both the good and the bad,” Sascha Samadi, an analyst with the German Wuppertal Institute for Climate, Environment and Energy, which carries out research on the energy transformation, told IPS.

The expert said that “at the start of the energy transition, everything was about how to rise up against the big energy companies that so many people hated,” while now the main driver of support for the transition is concern about climate change.

To move towards a low-carbon energy mix, “in the countries of Latin America, other aspects can be more important on the agenda, such as reducing dependence on imports or making supplies more stable,” he said.

In Germany, renewables accounted for 30 percent of the electricity produced in 2015 and this European nation is the third-largest producer of renewable energy – not including hydropower. It is third in wind energy and biodiesel and fifth in geothermal.

It is also a leader in per capita solar power, despite its relatively low amount of sunlight.

In the last decade, strides have been made in developing renewable energies in Latin America, a region highly dependent on fossil fuels, either because the countries are major producers of them, such as Argentina, Brazil, Colombia, Ecuador, Mexico, Peru and Venezuela, or because they depend on imports, like the nations of Central America or Chile.

Most countries in the region have included plans to foment the energy transition, policies to make production and consumption more efficient, and targets for the generation of renewable energy.

Reaching Germany’s goal, a low-carbon economy, requires social change and modifications in consumption patterns and industrial policies, and will force plants like the ThyssenKrupp steel mill in the city of Duisburg to replace coal with cleaner sources. Credit: Emilio Godoy/IPS

For example, Mexico passed in December an energy transition law, Chile has its 2050 energy plan, and Uruguay has a 2005-2030 energy policy. This legislation includes medium to long-term goals for the generation of renewable energy, tax incentives, and other actions aimed at a cleaner energy mix.

In 2015, Brazil drew more than 7.1 billion dollars in investment in renewables – 10 percent less than the previous year; Mexico drew 4.0 billion – double the 2014 level; and Chile, 3.4 billion – an increase of 150 percent, according to the report “Global Trends in Renewable Energy Investment 2016”.

Nations like Honduras and Uruguay also received over 500 million dollars in investment in renewables in 2015, according to the study produced by the United Nations Environment Programme Collaborating Centre for Climate and Sustainable Energy Finance at the Frankfurt School of Finance & Management.

The study reports that investment in Brazil climbed from 800 million dollars in 2004 to 7.1 billion in 2015.

Without counting the region’s leading producer, Latin America captured 1.7 billion in investment in 2004, rising to 12.8 billion in 2015. But last year’s capital flows fell from 2014 levels, due to factors such as political instability in some countries and low oil prices.

The region generates 209,419 MW of renewable energy, of which hydropower represents 171,960.

To promote a low-carbon energy mix, there is an element in which Latin America should try to emulate Germany, Sophia Schönborn, an analyst with the German multisectoral organisation on energy KlimaDiskurs.NRW e.V, told IPS.

“Germany’s transition shows the importance of bottom-up decision-making and listening to the public’s concerns. It was not imposed; society pushed for changes in the energy model,” said the expert.

In the hands of the market

Germany has reached the point where it is producing excess renewable energy. As a result, parliament revoked fixed rates for renewables as of January 2017, and created auctions for all sources of clean energy.

The reform of the renewable energy law that will go into effect at that time rewards suppliers that have the lowest prices, sets caps on energy generation, and leaves fixed rates in place only for cooperatives and small-scale producers.

Under the German model, citizens can generate their own electricity, and can even sell it to the grid, as part of the construction of what experts and organisations are referring to as the “energy citizenship”. But that is far from being the reality in Latin America.

The fixed rates, which included a surcharge to support suppliers of renewables, helped fuel the expansion of alternative sources in Germany.

In Latin America, countries such as Ecuador, Honduras, Panama, Peru and Uruguay use surcharges or mix them with net metering, which allows consumers who produce their own electricity to use it at any time, rather than when it is generated. The consumers only pay the difference between what they consume and what they generate.

And countries like Chile, Mexico and Peru have put in place renewable energy auctions since 2015, which have led to a drop in prices per kilowatt-hour, partly due to their vast renewable sources, according to the Global Status Report 2016 released in June by REN21, the Renewable Energy Policy Network for the 21st Century.

According to experts, the recent swings are a signal to Latin America with respect to the handling of the renewable energy market, to avoid risks of over-production or excessive payments to suppliers.

Samadi stressed that “the costs of the expansion of renewables are paid by consumers in Germany.”

“This might not be a good mechanism for the countries of Latin America, where low energy prices could be important for social development and cohesion,” he said. With this in mind, he suggested taxes or special funds.

There is another lesson too. “If the huge growth in renewables was just starting now in Germany, with today’s low technological costs our overruns for generation would be lower than what we pay now.”

In his view, “the countries that start to invest heavily today in wind and solar energies will not face the same high costs as Germany, especially when the solar potential in most of Latin America is taken into account.”

Schönborn concurred, stressing the competitive costs of renewable sources. But she warned of the risk of “social division” for those who cannot generate their own energy and must buy it from the grid.

This inequality “requires intervention by the state to guarantee access,” she said.

In Germany, wind and solar energy coexist with energy generated by burning fossil fuels in the Western state of North Rhine-Westphalia.

COLOGNE, Germany, Jul 19 2016 (IPS)

Immerath, 90 km away from the German city of Cologne, has become a ghost town. The local church bells no longer ring and no children are seen in the streets riding their bicycles. Its former residents have even carried off their dead from its cemetery.

Expansion of Garzweiler, an open-pit lignite mine, has led to the town’s remaining residents being relocated to New Immerath, several kilometres away from the original town site, in North Rhine-Westphalia, whose biggest city is Cologne.

The fate of this small village, which in 2015 was home to 70 people, reflects the advances, retreats and contradictions of the world-renowned transition to renewable energy in Germany.

Since 2011, Germany has implemented a comprehensive energy transition policy, backed by a broad political consensus, seeking to make steps towards a low-carbon economy. This has encouraged the generation and consumption of alternative energy sources.

But so far these policies have not facilitated the release from the country’s industry based on coal and lignite, a highly polluting fossil fuel.

“The initial phases of the energy transition have been successful so far, with strong growth in renewables, broad public support for the idea of the transition and major medium and long term goals for government,” told IPS analyst Sascha Samadi of the non-governmental Wuppertal Institute, devoted to studies on energy transformation.

Renewable electricity generation accounted for 30 percent of the total of Germany’s electrical power in 2015, while lignite fuelled 24 percent, coal 18 percent, nuclear energy 14 percent, gas 8.8 percent and other sources the rest.

This European country is the third world power in renewable energies – excluding hydropower – and holds third place in wind power and biodiesel and fifth place in geothermal power.

Germany is also renowned for having the highest solar power capacity per capita in photovoltaic technology, even though its climate is not the most suitable for that purpose.

But the persistence of fossil fuels casts a shadow on this green energy matrix.

“The successful phasing out of fossil fuels entails a great deal of planning and organisation. If we do not promote renewables, we will have to import energy at some point,” Johannes Remmel, the minister for climate protection and the environment for North Rhine-Westphalia, told IPS.

Germany has nine lignite mines operating in three regions. Combined, the mines employ 16,000 people, produce 170 million tonnes of lignite a year and have combined reserves of three billion tonnes. China, Greece and Poland are other large world producers of lignite.

Garzweiler, which is owned by the private company RWE, produces 35 million tonnes of lignite a year. From a distance it is possible to see its cut-out terraces and blackened soil, waiting for giant steel jaws to devour it and start to separate the lignite.

Lignite from this mine fuels nearby electricity generators at Frimmersdorf, Neurath, Niederaussen and Weisweiller, some of the most polluting power plants in Germany.

RWE is one of the four main power generation companies in Germany, together with E.ON, EnBW and Swedish-based Vattenfall.

Coal has an expiry date

The fate of coal is different. The government has already decided that its demise will be in 2018, when the two mines that are still currently active will cease to operate.

The Rhine watershed, comprising North Rhine-Westphalia together with other states, has traditionally been the hub of Germany’s industry. Mining and its consumers are an aftermath of that world, whose rattling is interspersed with the emergence of a decarbonized economy.

A tour of the mine and the adjoining power plant of  Ibberbüren in North Rhine-Westphalia shows the struggle between two models that still coexist.

In the mine compound, underground mouths splutter the coal that feeds the hungry plant at a pace of 157 kilowatt-hour per tonne.

In 2015 the mine produced 6.2 million tonnes of extracted coal, an amount projected to be reduced to 3.6 million tonnes this year and next, and to further drop to 2.9 million in 2018.

The mine employs 1,600 people and has a 300,000 tonne inventory which needs to be sold by 2018.

“I am a miner, and I am very much attached to my job. I speak on behalf of my co-workers. It is hard to close it down. There is a feeling of sadness, we are attending our own funeral”, told IPS the manager of the mine operator, Hubert Hüls.

Before the energy transition policy was in place, laws that promoted renewable energies had been passed in 1991 and 2000, with measures such as a special royalty fee included in electricity tariffs paid to generators that are fuelled by renewable energy sources.

The renewable energy sector invests some 20 billion dollars yearly and employs around 370.000 people.

Another measure, adopted in 2015 by the government in Berlin, sets out an auction plan for the purchase of photovoltaic solar power, but opponents have argued that large generation companies are being favoured over small ones as the successful bidder will be the one offering the lowest price.

Energy transition and climate change

Energy transition also seeks to meet Germany’s global warming mitigation commitments.

Germany has undertaken to reduce its greenhouse gas emissions by 40 per cent in 2020 and by 95 per cent in 2015. Moreover, it has set itself the goal of increasing the share of renewable energies in the end-use power market from the current figure of 12 per cent to 60 per cent in 2050.

In the second half of the year, the German government will analyse the drafting of the 2050 Climate Action Plan, which envisages actions towards reducing by half the amount of emissions from the power sector and a fossil fuel phase-out programme.

In 2014, Germany reduced its emissions by 346 million tonnes of carbon dioxide, equivalent to 27.7 per cent of the 1990 total. However, the German Federal Agency for Environment warned that in 2015 emissions went up by six million tonnes, amounting to 0.7 per cent, reaching a total of 908 million tonnes.

Polluting gases are derived mainly from the generation and use of energy, transport and agriculture.

In 2019, the government will review the current incentives for the development of renewable energies and will seek to make adjustments aimed at fostering the sector.

Meanwhile, Germany’s last three nuclear power plants will cease operation in 2022. However, Garzweiler mine will continue to operate until 2045.

“There are technological, infrastructure, investment, political, social and innovation challenges to overcome. Recent decisions taken by the government are indicative of a lack of political will to undertake the tough decisions that are required for deep decarbonisation”, pointed out Samadi.

Companies “now try to mitigate the damage and leave the search for solutions in the hands of the (central) government. There will be fierce debate over how to expand renewable energies. The process may be slowed but not halted”, pointed out academic Heinz-J Bontrup, of the state University of Applied Sciences Gelsenkirchen.

Meanwhile, the regional government has opted to reduce the Garzweiler mine extension plan, leaving 400 million tonnes of lignite underground.

ST. AUGUSTINE, Florida, May 23 2014 (IPS)

Japanese Buddhist and president of Soka Gakkai International (SGI) Daisaku Ikeda’s Peace Proposal 2014 elevated my focus from the daily news to my longer term concerns for more peaceful, equitable and sustainable human societies to assure our common future. These broader concerns are now shared by millions of humans who have transcended purely personal, local and nationalistic goals and become prototypical global citizens.

Hazel Henderson

Breakdowns in our current institutions now cause daily crises and are, as always, driving new breakthroughs as humans seek new solutions.  Stress has always been a tool of evolution – as recorded in the 3.8 billion years of life forms on our home planet.

Today’s crises are all consequences of our former myopic technological and social innovations addressing short-term problems without anticipating their system-wide longer-term effects.  This is how I became concerned about how human burning of fossil fuels and digging in the Earth for our energy which led me to join the World Future Society in the 1960s.  I was then leading an effort to clean New York City’s polluted air, living close by a huge coal-burning power plant pumping smoke and soot into the play park where I and other mothers watched our infants.

Fast forward to 2014, and I’m still a card-carrying futurist and on the Planning Committee of the Millennium Project which tracks our human family’s 15 Global Challenges.  Our latest State of the Future Report 2014 tracks where we are progressing and where we are falling short in addressing these challenges: sustainable development and climate change; water; population and resources; democratisation; long-term policy making; globalisation of information technology; rich-poor gap; health; decision-making capacities; conflict resolution; improving the status of women; transnational organised crime; energy; science and technology, and global ethics.  This Millennium Project has participants from academia, government, civic society and businesses in fifty countries.

“Political will in many countries is still hostage to special interests, lobbying and money from these legacy sectors and their perverse subsidies”
At the same time, Daisaku Ikeda, also my esteemed co-author of Planetary Citizenship, leader of SGI’s 12 million members, outlines his annual Peace Proposal for 2014, as he has done since 1983. Ikeda, born in 1928, is one of the world’s most distinguished global citizens.

Ikeda’s Peace Proposal 2014 – Value Creation for Global Change: Building Resilient and Sustainable Societies – engages  United Nation issues: moving beyond the 2000 Millennium Development Goals (MDGs) to the Agenda of 191 countries in Rio+20 in Brazil in 2012, as Sustainable Development Goals (SDGs).  These now embrace the transition from fossil and nuclear energy to the more decentralised, cleaner, greener, knowledge-richer, green economies now under way.  I came to similar conclusions in my Mapping the Global Transition to the Solar Age (2014). Retiring human uses of fossil fuels, uranium and nuclear power plants and weapons is now feasible with current technologies as outlined in many reports covered in the 2014 Green Transition Scoreboard®.

Political will in many countries is still hostage to special interests, lobbying and money from these legacy sectors and their perverse subsidies. Civic movements worldwide are pressuring pension funds and university endowments to divest from fossilised sectors and shift to cleaner, greener, more sustainable investments.  Veteran financial experts, including Jeremy Grantham and Robert A. G. Monks, now join these critics, along with asset managers offering “fossil-free” portfolios which often outperform dirtier assets. As nuclear power plants are being decommissioned in the United States and Europe due to cheaper wind, solar and efficiency alternatives, many in Asia are still planned, even in China which now leads the world in solar energy.

Huge conceptual breakthroughs are needed to shift old paradigms and theory-induced blindness. One such is the rapidly developing proposal “Iran Goes Solar” by the Planck Foundation for Iran to end run the entire political debate about its right to develop civilian nuclear power. This could bypass all sanctions, Israel’s concerns about another nuclear weapons state in the Middle East and “electrify” the upcoming United Nation Conference on the Nuclear Non-Proliferation Treaty (NPT).

While Ikeda rightly calls for a “non-use” agreement under NPT, the Planck Foundation’s plan is a paradigm shifter. Iran could accelerate its transition from both nuclear and fossil fuels by immediately acquiring blocks of shares in China’s solar energy companies and then purchasing as many of their solar panels as possible. This is already a much cheaper alternative to building nuclear reactors or fossil fuel power plants.

Iran’s bountiful oil reserves would stay underground as valuable feedstocks for industrial use rather than burning them, a plan I proposed in the NBC-TV Today Show in 1965!  Details of the Planck “Iran Goes Solar” plan also call for expanding rail services on the Silk Road to China, greening desert lands with salt-loving plants as in their DesertCorp plan for expanding seawater-based agriculture in many desert regions.

Today’s breakdowns are indeed producing the new systemic plans and breakthroughs long-proposed by futurists and planetary citizens. All these plans for our common future and green economies are covered by Ethical Markets Media(United States and Brazil), but often overlooked in mainstream media. (END/COPYRIGHT IPS)

Excerpt:

Whenever hot water from the kitchen tap or the bathroom shower goes down the plughole, a substantial amount of heat energy goes with it. In some German buildings this is being recovered and used to heat buildings in the winter and run air conditioning systems in the summer, representing a real energy-saver.

The energy, recovery of which allows reduction of fossil fuel consumption and greenhouse gas emissions, flows in the drains. That is precisely where the city government of Fürth, in the southeastern German state of Bavaria, went to find it.

For the past two years, the city government has been using energy from wastewater in pipes close to the town hall to help heat the building during the winter. Recovering it is inexpensive and only requires simple heat-exchange and heat transmission methods.

“Drain pipes in the vicinity carry at least 150 litres of water per second, at a temperature of between 12 and 16 degrees Celsius, enough to provide heating for the town hall,” Katrin Egyptiadis-Wendler, the engineer in charge of buildings administration in the city of Fürth, told IPS.

“In the winter of 2010, in the framework of the German law promoting renewable energy, we changed the old heating system and installed a new, very efficient gas-fired system, and a heat-exchange and transmission mechanism for the drains,” Egyptiadis-Wendler said.

The essential requirements for recovering energy from wastewater are a constant flow of water through the pipes — at least 15 litres per second — and a minimum temperature of 12 degrees. “The wastewater must not be mixed with rainwater, which is too cold to use,” the engineer stressed.

In Fürth, the city government installed a series of heat-exchangers along a 70-metre length of drain pipes, where they absorb heat from used water. By means of a heat pump, the temperature is raised to 50 degrees and then injected into the heating system for the town hall, built over 170 years ago.

“The only additional energy we need is the electricity for the pump,” said Egyptiadis-Werner. “The system provides 70 percent of the heating for the building. Only when the weather is extremely cold do we need to use the gas-fired system we installed in 2010.”

The energy savings mean that each year, 130 fewer tonnes of carbon dioxide (CO2, a major greenhouse gas) are emitted, and 14 fewer tonnes of fine particles. Moreover, 65 percent of the annual 85,000 cubic metres of gas used before the system was installed is now saved.

The total investment in the new town hall heating system, amounting to 550,000 euros (733,000 dollars) will be completely amortised by 2018.

So far only some 30 buildings in Germany, particularly large shopping malls and hotels, are using similar systems to recover energy from drain pipes, or from the heat generated within the facilities.

But according to the German Association for Water, Wastewater and Waste (DWA), they could be installed at many more sites, because the requirements for good results are relatively simple to satisfy: a heat source nearby, to avoid heat losses over distance, a constant volume of warm water, and a reasonable minimum temperature.

“It’s very easy to absorb heat from pipes, whether they are for wastewater or for air circulation. However, one must assess whether the energy gain justifies the investment required,” Johannes Lohaus, the manager of DWA, told IPS.

The method can be reversed in the summer. Heat absorbed by used water in drain pipes, or from the buildings themselves, can be used to feed air conditioning systems and cool the buildings.

A furniture and decoration store in Berlin belonging to the IKEA chain, which covers an area of 43,000 square metres, uses a system identical to that employed by the Fürth town hall in winter, absorbing heat from wastewater pipes. And in summer it applies the reverse process, extracting heat from the building and transforming it into cold water to feed the air conditioning system.

“This way, we don’t need conventional air conditioning and we reduce our CO2 emissions by 700 tonnes a year,” Simone Setterberg, an IKEA spokeswoman, told IPS.

However, there is a negative aspect to heat recycling: cooling the drain pipes endangers the bacteria that provide a natural filter for the elimination of impurities from wastewater.

“Bacterial metabolism is more efficient when the temperature of the wastewater is higher,” Lohaus, of DWA, explained.

“If the wastewater is cooled too much by the process of heat exchange, the bacteria do not survive, and aeration of the wastewater must be carried out in order to achieve the same level of cleansing as the bacteria provided, which implies higher energy consumption,” he said.

RAMALLAH, Occupied West Bank, Dec 16 2012 (IPS)

Afnan Hamad stands proudly in front of a booth at the Ramallah Cultural Palace exhibition hall, three plastic bottles filled with discoloured liquid on the table in front of her.

“We designed a device to convert plastic waste into gasoline, kerosene and diesel fuel,” explains the 23-year-old chemical engineering graduate from An-Najah National University in Nablus, pointing to one of the bottles. “We hope to see a real factory built, and be the first supplier of alternative fuel in Palestine.”

Hamad and her colleagues – Marah Jamous, Mohammad Manasrah and Rahal Rashed – displayed their machine to convert waste into reusable fuel as part of the ‘Made in Palestine 2012’ fair held last week in Ramallah, an annual event that aims to promote skills and innovations that often get buried beneath the hardships of daily life in Occupied Palestine.

While it started off as a miniature experiment, Hamad’s machine can now hold ten kilogrammes of plastic waste and produce nine litres of fuel, she explained, adding that the invention was designed to address economic and environmental problems prevalent in the area.

“Using our device, we can get rid of a huge amount of waste, which is difficult to do in Palestine,” she told IPS. “Also since we don’t have petrol here, we can produce fuel at a lower cost. One litre of fuel will cost five shekels (about 1.30 dollars).”

Now in its seventh year, the ‘Made in Palestine’ event was co-sponsored by the local Palestinian organisation Al Nayzak and the Swedish NGO Diakonia. Two exhibitions were held, one in Ramallah and one in the Gaza Strip, showcasing over 20 innovations in the fields of engineering, IT, biology and other sciences.

“It doesn’t only tackle science, innovation and technology; (the event) also addresses the idea of business entrepreneurship. We aim to create scientific entrepreneurs who are able to make and found businesses on those innovations that they’ve thought about and put into action,” explained Maha Thaher, international relations officer at Al Nayzak.

With offices in Gaza, Jerusalem and Ramallah, Al Nayzak aims to build a more vibrant scientific culture in Palestine, and encourage critical thinking and science education among Palestinian youth.

“We don’t want students to just avoid these subjects (until) they disappear from our community,” Thaher told IPS, adding that Palestinian students are endowed with a range of talents, which deserve to be nurtured, rather than ignored, by the education system.

“This is the one thing that occupation fails to seize and severely damage: we can (always) count on our minds, our intellect and our people,” she added.

Other innovations on display in Ramallah included a multi-tasking robot equipped with special wheels that allow it to move from left to right without turning, a cell phone application that helps users reserve library books in advance, and an onion planting machine.

Planting onion bulbs can be a tricky exercise, but this machine “plants the bulbs in exactly the right way”, explained inventor and local farmer Ibrahim Da’abes, who owns 100 dunams (nine square kilometres) of farmland in the Jordan Valley area of the West Bank and believes his machine will cut farming costs in half.

“The cost is much lower than employing workers to do it by hand. Bigger farmers would need this machine,” he told IPS.

At another booth, 20-year-old computer engineering student Rasha Saffarini, and her colleagues Isra’ Al-Qatow and Abdullah Al-Qatow, showcased their cell phone application that helps people reach a healthy weight.

Called ‘Healthy Gate’, the application asks users for various inputs – including current and ideal weight, age and food preferences – and sets alarms to alert them when, and what, they should eat throughout the day.

“Because of the difficulty of going to the gym, we make it easy for people to be their ideal weight,” said Saffarini, who is in her last year at the Palestine Technical University in Tulkarm, a city in the western West Bank.

Many of the participants of the ‘Made in Palestine’ fair were women. This, according to Thaher, highlights a growing acceptance within the Palestinian community of science education as a legitimate pursuit.

Families have generally been sceptical of the idea of their daughters pursuing dreams of making an important scientific invention or discovery, since this strays so far from the traditional path women are expected to walk.

“At times we had to go door-to-door and talk to parents about how they should let their daughters be involved in such programmes and build on their ideas,” Thaher said.

“But once the parents see their children so involved in this system that cares for their scientific approaches, they start to think differently themselves.”

According to Hamad, “Our families are very proud and so are we. We invented something new for Palestine.”

A joint project by the energy and agriculture authorities in Argentina is seeking to boost electricity generation from forestry waste and other rural products which have enormous potential, according to experts.

The Probiomasa programme, launched this year, is planning to increase energy supply from burning organic waste, from 3.5 percent of the current energy mix to 10 percent in 2015.

“The goal is to raise biomass participation in electricity generation by means of a platform for private projects in need of promotion,” said Miguel Almada, head of the agroenergy area of the Ministry of Agriculture, Livestock and Fisheries.

“Many projects are already under way, or are negotiating tariffs,” he told IPS.

The idea is to save money that now goes to importing fossil fuels for thermal power stations, help improve living conditions in isolated rural areas, and reduce pollution.

When biomass is processed for energy it emits less global warming-causing greenhouse gases than fossil fuels. In addition, efficient use of biomass contributes to the conservation of soil and water.

Claudia Peirano of the Argentine Forestry Association told IPS that biomass is already a key element in this industry for producing energy, for its own use and for sale of surplus products.

For example, the timber company Alto Paraná and the pulp and paper company Papel Misionero, both located in the northeastern province of Misiones, have their own electricity generation plants based on sawdust from their forestry plantations, she said.

“The excess supplies the boilers of hotels (at the Iguazú Falls) for hot water and for heating swimming pools,” she said. It also contributes to the national electricity grid, she added.

Peirano said that wood chips could be used to make cellulose or paper, with a higher added value than biomass, but the investments required would be greater and would take longer to yield returns.

According to a study carried out with the support of the U.N. Food and Agriculture Organisation (FAO), Argentina has the potential to generate half the country’s total energy supply by burning biomass.

The assessment by the FAO and government and technical bodies in Argentina mapped the biomass resources in each province to determine the available potential.

The study’s methodology made it possible to identify, quantify and locate production and consumption of biomass throughout the country.

The study, “Análisis del Balance de Energía Derivada de Biomasa en Argentina” (Analysis of the Energy Derived from Biomass in Argentina) concludes that biomass production today is “significantly higher” than official estimates and that the country has “an enormous potential of available biomass” over and above what is already used.

The report’s authors indicate that biomass production could increase from the 7.9 million tonnes produced at present to 148 million tonnes. The province with the most resources is Misiones in the northeast, but they point out that there are others.

Based on different waste products, the northern provinces of Santiago del Estero, Tucumán, Salta, Chaco and Formosa would be good producers, as well as the central province of La Pampa, and Tierra del Fuego in the far south.

Unlike biofuels, which are manufactured from specific energy-rich crops, biomass is made out of organic waste from other activities.

The waste comes from the forestry industry, wine-making, rice mills, sugarcane plantations and sugar mills, yerba mate plantations, the cotton, oil, peanut and fruit industries, and others.

Despite its potential, the FAO considers that biomass has so far been the “Cinderella” of energy sources, without political visibility or recognition in development planning in many countries, including Argentina.

FAO, which published its study in 2009 at the request of the Argentine government as a step towards the official launch of the Probiomasa programme, says the use of biomass resources is not just an environmentally-friendly option.

As well as reducing the contribution to global warming, biomass energy promotes rural development, adds value to agricultural production, bolsters the growth of regional economies and creates quality jobs in the countryside.

In an interview with IPS, Jorge Hilbert, an engineer and the coordinator of the National Bioenergy Programme at the National Institute of Agricultural Technology (INTA), said the government wishes to advance in this kind of development through the Probiomasa programme.

“The FAO study (in which Hilbert collaborated) shows the productivity and quantity of waste generated by the agricultural and forestry industries at the national level, but now more precise work is being done for each province and the municipalities,” he said.

In any case, the expert said, potential is one thing and economic feasibility another. “The resource is available, but if the price paid for the energy is lower than what it costs to produce, it is not viable,” he said.

Tariffs are a key issue, as the other sources who spoke to IPS also pointed out. “If the prices aren’t right, there won’t be any business,” Hilbert said.

However, he was confident this debate would be settled now that the programme depends not only on the Agriculture Ministry but also on the Ministry of Federal Planning, which includes the area of energy and sets tariffs.

Jeepney drivers and operators are using Eway54's Ecodiesel made from used cooking oil. Credit: Kara Santos/IPS

MANILA, Jun 22 2012 (IPS)

For the past three months, a transport group in the Philippines has been making use of biodiesel processed from used cooking oil for their jeepneys.

Jeepneys, public transport vehicles originally made from U.S. military jeeps left over from World War II, are one of the most popular means of transport in the country.

Pasang Masda, a national association of jeepney drivers and operators, has partnered with EWay 54, a company dealing in the propagation and education of alternative fuels for the benefit of the environment.

Eway54 Ecodiesel is made from used cooking oil gathered from hundreds of fast food restaurants throughout Metro Manila.

According to Pasang Masda President, Roberto Martin, the biodiesel has proven good for health and the environment as well as their livelihood.

“The biodiesel from used cooking oil has been a big help to the drivers. We tried this for three months, and we haven’t encountered any problems with our vehicles yet,” Martin told IPS.

“Drivers save as much as two pesos per liter. The drivers who have short routes and consume up to 15-20 liters a day save as much as 40 pesos (0.94 dollars) per day while those plying longer routes can save roughly 80 pesos (1.89 dollars) a day. The extra money they save can help them buy more rice to feed their families,” said Martin.

Aside from helping drivers increase their savings due to lower fuel costs, Martin added that the group has documents showing positive developments in the biodiesel cleaning the vehicles’ engines.

“Before we started using the biodiesel, many jeeps used to fail smoke emissions test, but with biodiesel, the engines run smoothly and smoke belching is no longer a problem,” said Martin.

Studies from the Department of Environment and Natural Resources (DENR) analysing Metro Manila’s air quality reveal that 65 percent of the total air pollution in the capital comes from motor vehicles.

Drivers of public utility vehicles like jeepneys can be slapped with penalties and fines for violating Republic Act 8749 or the Clean Air Act.

“The fine for smoke belching can range from 23-71 dollars depending on the number of offenses. Our drivers have been able to avoid these heavy fines by using the biodiesel,” added Martin.

According to EWay 54’s plant supervisor Glenn Cabrera, this is because biodiesel is much cleaner than regular fuel.

“The emissions that come from biodiesel-powered engines are very clean. Biodiesel removes the carbon deposits from the engine and reduces smoke-belching from vehicles, so it’s more environmentally-friendly,” Cabrera told IPS during a visit to EWay’s manufacturing plant.

The biodiesel from used cooking oil is also cheaper compared to biodiesel sold in gasoline stations. EWay 54 sells the biodiesel in bulk to Pasang Masda at 38.50 pesos per liter, which is three to four pesos cheaper than the current market value. The transport group redistributes the biodiesel among its members in their different stations around the Metro.

EWay 54 claims that the use of alternative fuels like biodiesel can contribute to clean air, is more environmentally and scientifically safe, and is a cheaper and cleaner alternative to fossil fuels.

According to Ricky Cuenca, managing director of Eway54, the demand for biodiesel is very high.

“Demand has been extremely high because Pasang Masda will take any volume we produce, but we are only producing one to two percent of their total requirement,” Cuenca told IPS.

Pasang Masda has over 17,000 jeepneys in its membership, and EWay currently delivers biodiesel to six of the transport group’s 176 stations.

Aside from the transport group, EWay 54 is also working with four private companies that are using biodiesel for their transport, logistics and warehouse operations.

However, Cuenca says that getting enough supply of raw materials is a major challenge due to the high demand for used cooking oil. EWay 54 sources the bulk of its used cooking oil from fast food restaurants, but they are constantly on the lookout for other possible sources.

“It has been very difficult, knowing that used cooking oil is a commodity that is being used as an additive for animal feeds and also in the illegal trade of refiltering used oil to be resold in the markets,” said Cuenca.

A new bill prohibits the practice of using recycled cooking oil, except for industrial purposes, due to potential health hazards.

“We started out making 50 gallons a day but now, we are up to 3,000 -4,000 gallons a week,” said Cuenca.

Collection of used cooking oil also remains a logistical challenge. Every day, the company collects as many as 150-200 tins of used cooking oil from their suppliers. The manufacturing plant has the ability to process a minimum of 1,000 liters a day, depending on the availability of the raw materials.

The process includes pre-filtration to remove the food particles and other solid materials from the oil. Then the conversion process, which can take five hours, transforms the used cooking oil to biodiesel by removing the glycerin. The oil undergoes three stages of washing to remove excess glycerin, then the oil is heated to a certain temperature so the excess water evaporates. The oil is cooled down and re-filtered before the final product is ready to be sold to clients.

According to Henry Palacios, EWay’s director for Business Development, there is a movement towards using renewable energy in the country because of the environmental benefits.

Aside from giving off cleaner emissions, biodiesel is nontoxic and comes from renewable biological materials such as vegetable oils or animal fats, making it more sustainable than fossil resources used to make diesel fuel. EWay is currently exploring other possible clients.

“Other companies that could benefit from biodiesel include private companies that need fuel for forklifts or transport trucks, condominiums or establishments that use generators, and even boats and shipping companies,” Palacios told IPS.

According to Cuenca, at 20 percent blend, the biodiesel can lower CO2 and sulfur emissions by 15 and 30 percent respectively. Pollutants can be further lessened the higher the percentage blend of the biodiesel.

Cuenca stressed that having clients in the public transport groups that consumes four billion litres of diesel every year in the Philippines has made a large impact.

EWay claims that since they started their journey in April 2011, they have “mitigated over 1.7 million pounds of carbon dioxide. That’s 765 tons of pollutants in the air we breathe, roughly equal to the work of 35,000 mature trees, every year.”

Cuenca added that they need to step up their efforts to educate restaurants, oil suppliers, new users and the public in general.  According to Cuenca, any vehicle with a diesel engine can immediately use the biodiesel without having to convert anything in their engines.

“Many people ask us if there are any modifications or changes they need to do with their engines, we say no. The only thing we need to change is our mindset and perceptions of renewable fuel,” said Cuenca.
