As countries failed to reach a substantive climate change pact at Copenhagen last week, action at the subnational level has emerged as one of the likeliest paths toward significant climate action.
As governments negotiate future greenhouse gas emissions in Copenhagen, a recent report from Environment America has highlighted the problem of the United States' older coal-fired power plants, which generated nearly three-quarters of U.S. carbon dioxide emissions from power plants in 2007.
Cutting governmental subsidies for fossil energy could lead to a 10 percent reduction in greenhouse gas emissions by 2050 as compared to 1990 levels, says a recent study by the Organisation for Economic Cooperation and Development.
"Energy is an instrument of power. Whoever has energy, controls the world," Cuban expert Luis Bérriz said in an address to Klimaforum, the civil society meeting being held in parallel to the UN conference on climate change in the Danish capital.
The residents of the Puna, the dry Andean highlands in northern Argentina, are cut off from everything - except the sun. Living on arid land thousands of metres above sea level, they are on their way to becoming "solar villages."
When Innovation Centre Iceland (ICI) managers began courses in farming renewable energy in October they were unprepared for the enthusiastic response from citizens.
Bill McKibben is a U.S. writer, environmentalist and the founder of 350.org, an international climate campaign. His first book, "The End of Nature", was published in 1989 and is regarded as the first book written for a general audience about climate change.
Tomorrow’s polluters are today’s emerging economies. To develop without retracing the polluting steps of the West, requires green technology, an expensive option for Africa.
Congress has given new momentum to a bill imposing unilateral sanctions on Iran - a move seen by many as an ineffective form of sanctions and potentially antagonistic against valuable U.S. allies on the U.N. Security Council. This comes ahead of the end of the year deadline set by U.S. President Barack Obama for Tehran to respond to a proposed agreement to export most of its enriched uranium for processing in Russia and France.
As Finnish energy major Neste Oil scales up production of its ‘green’ diesel NExBTL, environmental activists fear that more land will go under palm oil plantations at the expense of Southeast Asia’s threatened rainforests.
Being the world’s largest producer and exporter of ethanol it is natural for the Brazilian government and its partners to push biofuels as the only real alternative for a world trying wean itself away from fossil fuels that contribute to global warming.
For close to three decades, Jeremiah Mkhonta has earned a living by selling firewood by the roadside. It's not exactly lucrative: the father of 15 often goes for a fortnight without even selling a single four dollar bundle of firewood.
With or without a binding deal at the climate talks in Copenhagen this month, it seems the world may have to cut its oil consumption, as emerging geological and economic trends limit the availability and affordability of petroleum.
Electricity is indispensable to modern life, but its generation is responsible for 40 percent of the carbon dioxide emissions that cause global warming and climate change.
The Mexican company BioFields will begin production in 2014 of an algae-based biofuel at a site 300 kilometres from its border with the United States, which is likely to be its biggest customer.
A paper mill that runs without fossil fuels and has a neutral carbon footprint? That's the goal for Flambeau River Papers in Park Falls, Wisconsin, and the company is already on its way, thanks to a switch to biomass fuel, plus a biorefinery in the works.
As Indian Prime Minister Manmohan Singh wound down his state visit to the United States, Indian analysts say a major achievement has been ensuring that the civilian nuclear agreement between the two countries is on track.
With the flip of a switch, a light comes on or an electric toothbrush revs to power. If service is cut, either for repairs or because of a natural cause, there will most likely be much fuss about how quickly power is restored - to people who live in the developed world.
When Obed Mumba first came to the Zambian copper mining town of Ndola in search of work, it was still known reverently as "Ku kalale" - the land of the white man. In the decades since, he has witnessed his Kabushi township outgrow the limited dreams of its planners.
Whether a new internationally binding treaty to reduce greenhouse gases and forestall climate change will be signed next month remains to be seen. What is clear though, is that if there is a place in the world that deserves to be the stage where this treaty ought to be signed, it is the Danish capital of Copenhagen.
The sun is setting slowly over Dar es Salaam's Tabata Changombe neighbourhood. Ameenah and Skukulu Juma lean against the corrugated iron walls of their makeshift charcoal shop.
