The food-versus-fuel debate has typically been used in reference to farmers in industrialized countries growing food crops, such as corn, to sell to biofuels producers.
Leading experts on climate change science and technology are calling on the federal government to launch a coordinated investigation of the potential effectiveness, feasibility, and consequences of so-called geoengineering.
The US is unlikely to meet some specific biofuel mandates under the current Renewable Fuel Standard by 2022 unless new technologies are developed or policies change.
The inventor who gave the world the Segway - you know, that upright-riding, personal-transportation thing - is now seeking a patent for an inflatable wind turbine.
The large increase in atmospheric carbon dioxide at the end of the last ice age wasn't released by the oceans, scientists have concluded.
The key to saving vast amounts of energy? It's right there on your kitchen counter, say scientists at Oregon State University.
The global uptake of carbon by land plants could be much higher than previously thought, meaning that the carbon cycle models used to predict climate change could be wrong.
Democratic Arkansas Senator Mark Pryor recently announced the Clean Energy Technology Manufacturing and Export Assistance Act of 2011.
A new, "ultra-green" genomics research center is taking shape at the University of California San Diego (UCSD).
A new consortium that could put billions of dollars of clean-energy and energy-efficiency investment into commercial developments in the United States is getting off the ground.
Since its May launch, wind power developers have committed a total of $2.7 billion - and placed more than 2 gigawatts (GW) in orders - for the 1.6-100 wind turbine from General Electric (GE).
GE is trying to figure out how to make larger generators and the Obama administration is funding an R&D center in Maine that will make and test giant turbines.
Optofluidics - now that's something we haven't really seen before on our virtual pages.
Bowhead whales have navigated the Northwest Passage between the Atlantic and Pacific oceans for what could be the first time in nearly 10,000 years.
What do Amazon, Netflix, Google and Facebook have in common?
Automobile designer Gordon Murray Design and chemical company Toray recently announced the development of a new prototype electric sports car dubbed the Teewave AR.1.
Subway systems consume enormous amounts of energy. To further complicate things, they usually require energy in short, intense jolts.
Tar balls washed up on the shore of the Gulf of Mexico earlier this month by Tropical Storm Lee show that oil from last year's Deepwater Horizon spill isn't degrading as quickly as expected.
Internal combustion engines are terribly inefficient machines.
About 60 percent of the energy generated by an internal combustion engine is lost - half from exhaust heat.
There's been a sharp rise in global CO2 emissions over the last ten years, despite reductions by industrialized countries.
