"Flammable ice" or methane hydrates, could be the world's last great source of carbon-based fuel - assuming the methane can be mined from the crystal lattices of ice that trap it beneath ocean beds and permafrost.
A lick of solar-power paint could see the roofs and walls of warehouses and other buildings generate electricity from the sun, if research by UK researchers pays off. The scientists are developing a way to paint solar cells onto the steel sheets commonly used to clad large buildings.
International databases to share information about nuclear and radioactive materials are urgently needed to help deter potential nuclear threats, according to a team of scientific and policy experts.
A scientist who mapped his genome and the genetic diversity of the oceans said he is creating a life form that feeds on climate-ruining carbon dioxide to produce fuel.
Companies are racing to provide radioactive fuel for America's nuclear renaissance, and are powering debate along the way. Even as the government continues to oppose Iran's efforts to enrich uranium for power plants, projects to do just that are under way in the U.S.
Converting corn to ethanol in Iowa not only leads to clearing more of the Amazonian rainforest, researchers report, but also would do little to slow global warming.
Europe is considering plans to spend more than 5 billion pounds on a string of giant solar power stations along the Mediterranean desert shores of northern Africa and the Middle East.
Google will spend hundreds of millions of dollars to develop and help stimulate the creation of renewable energy technologies that are cheaper than coal-generated power.
A new study has concluded that space solar power is feasible, but leaves unanswered who should proceed and how. Taylor Dinerman argues that China, with its voracious appetite for energy, can play a role as both a customer and co-developer.
A new Pentagon study lays out the roadmap for a multibillion-dollar push to the final frontier of energy: a satellite system that collects gigawatts' worth of solar power and beams it down to Earth. The military itself could become the "anchor tenant" for such a power source, due to the current high cost of fueling combat operations abroad, the study says.
