A Mexican solar energy cooperative, Onergia, seeks to promote decent employment, apply technological knowledge and promote alternatives that are less polluting than fossil fuels, in one of the alternative initiatives with which Mexico is seeking to move towards an energy transition.
Solar energy has continued to expand in Brazil during the COVID-19 pandemic and should contribute to the economic recovery in the wake of the health crisis.
"The idea came to a group of schoolmates and me in 2014, but we never thought it could become a reality," says Sebastián Ieraci, 23, as he points to a multitude of photovoltaic solar panels shining on the roof of the Antonio Devoto High School in the Argentine capital.
The intense white brightness of the salt flats interrupts the arid monotony of the Puna in northwest Argentina, resembling postcards from the moon. Beneath its surface are concealed the world's largest reserves of lithium, the key mineral in the transition to clean energy, the mining of which has triggered controversy.
"On moonless nights it was very difficult to walk around this town," says Celia Vilte, a teacher from San Francisco, a highlands village of just 54 people in the extreme northwest of Argentina whose centre is not a town square but 40 solar panels, which provide one hundred percent of its electricity.
"Biogas is the best energy, it has no contraindications," and if you combine it with solar it becomes "the best energy business," at least in Brazil, says Anélio Thomazzoni.
A large steel wheel, 14 meters in diameter and 1.3 meters wide, could be the energy solution of the near future, generating 3.5 megawatts - enough to supply a city of 30,000 people, according to a company in the capital city of the state of Amazonas in northwest Brazil.
A school in the capital of Easter Island (Rapa Nui, in the local indigenous tongue) gives an example of clean management with the use of solar energy, rainwater recovery and an organic vegetable garden, as well as rooms and spaces built with waste materials.
Social organisations in the central Mexican municipality of Yecapixtla managed to halt the construction of a large thermoelectric plant in the town and are now designing a project to convert the installation into a solar panel factory, which would bring the area socioeconomic and environmental dividends.
“We can’t work just to pay the electric bill,” complained José Hilario dos Santos, president of the Residents Association of Morro de Santa Marta, a favela or shantytown embedded in Botafogo, a traditional middle-class neighborhood in Rio de Janeiro.
"Solar energy makes my happiness complete," said Divina Cardoso dos Santos, owner of one of 740 houses with photovoltaic panels on the rooftops in a settlement on the outskirts of this central Brazilian city.
"We can't work just to pay the electric bill," complained José Hilario dos Santos, president of the Residents Association of Morro de Santa Marta, a favela or shantytown embedded in Botafogo, a traditional middle-class neighborhood in Rio de Janeiro.
Young Peruvians plan to take advantage of the knowledge acquired in Brazil's semi-arid Northeast to bring water to segments of the population who suffer from shortages, after sharing experiences in that ecoregion on the multiple uses of renewable energies in communities affected by climatic phenomena.
“We want to make history," agreed the teachers at the Chiquinho Cartaxo Comprehensive Technical Citizen School. They are the first to teach adolescents about generating power from bad weather in the semi-arid Northeast region of Brazil.
Sousa, a municipality of 70,000 people in the west of Paraíba, the state in Brazil most threatened by desertification, has become the country's capital of solar energy, with a Catholic church, various businesses, households and even a cemetery generating solar power.
“Our main challenge is to get the project back on track," agreed the administrators of two affordable housing complexes, where a small solar power plant was installed for social purposes in Juazeiro, a city in northeast Brazil.
The West African nation of Guinea may be a signatory of the Paris Agreement, a global undertaking by countries around the world to reduce climate change, but as it tries to provide electricity to some three quarters of its 12 million people who are without, the commitment is proving a struggle.
Chile has become a model country for its advances in non-conventional energy, and is now debating whether citizens who individually or as a group generate electricity can profit from the sale of the surplus from their self-consumption - a factor that will be decisive when it comes to encouraging their contribution to the energy supply.
Promoting the widespread use of innovative technologies will be critical to combat the hostile effects of climate change and reduce greenhouse gas emissions, and many African countries are already leading the way with science-based solutions.
Every year, Amos Chandiringa, 43, a farmer in Nemaire village in Makoni district in northeastern Zimbabwe, laboriously waters his tobacco nursery with a watering can. The toil of the job often leaves him without the energy or time to do other household chores.
With India’s citizens clamouring for breathable air and efficient energy options, the country’s planners are more receptive than ever to explore sustainable development options, says Frank Rijsberman, Director-General of the Global Green Growth Institute (GGGI).
