Up to two-thirds of Earth's permafrost will probably disappear by 2200, say scientists, unleashing vast quantities of carbon into the atmosphere.
In 1997, an IBM computer known as Deep Blue was able to defeat human chess superstar Garry Kasparov. Today, the computer company is saying it has been able to match the gravity of that accomplishment in an achievement for the 21st century.
Geologists have been testing a technique to generate energy from magma, after molten rock unexpectedly flowed into an exploratory well they'd been drilling in Iceland.
The second night of the three-night Jeopardy "man versus machine" battle aired last night, and after a while it really stopped being interesting and felt more like a bloodbath.
A wind-powered car has just completed its first long road trip - from Perth to Sydney - at a cost of just $15.
Electric motorcycles have been gaining ground in the racing world, and Miika Mahonen, an industrial designer from San Francisco, thinks BMW should make one ASAP.
Rising sea levels could threaten an average of nine percent of the land within 180 US coastal cities by 2100.
Nearly half a decade of hard work from some of the most intelligent computer engineers in the world, many of them holding PhD's in at least one field, culminated in an event that began on Monday. The results?
We've seen New Energy Technologies announce a series of advances in its attempt to turn windows into solar panels, and now the company says it has a working, 1-square-foot see-through glass prototype capable of generating electricity.
The time has come to see if a computer can actually possess the rational thought and skill needed to beat a human in the ultimate competition of knowledge - Jeopardy.
Just how well has the American Recovery and Reinvestment Act (ARRA) done in increasing the nation's renewable energy capacity?
According to SBI Energy's new report, "ARRA Report Card: Two Years Later," the U.S. is making significant progress toward attaining the Obama administration's goal of doubling renewable generation capacity in the country over the next two years.
You think the Nevada desert, you think solar power. But that's not the case at Pahrump Valley High School, about 50 miles west of Las Vegas.
The school, scheduled to open in 2012, is being built with a geothermal heat pump (GHP).
LEDs are one of the few types of lighting that actually give you enough light to see by, while still being good for the environment... or maybe not.
President Obama's moon shot - a Kennedyesque call to have 1 million plug-in electric vehicles (EVs) on U.S. roads by 2015 - is certainly bold and welcome, but most likely out of reach.
Air Force researchers say they've managed to harness more than 99 percent of wave energy.
Net zero energy efficiency at "an unprecedented rate of affordability?" Well, that's what the first private commercial micro-grid project of its kind in California, known as 2500 R Street, promises to deliver.
A Swedish team has developed a technology that it says could halve fuel consumption by using the energy generated as a vehicle brakes.
Is it penance for all those old Chevrolet/GM gas-guzzlers still on the road? Forward-looking environmental stewardship? Basic good-neighborliness?
A combination of all three?
A diesel hybrid - now that's something kind of different. And, hey, why not make it a plug-in?
There will come a day when an electric vehicle (EV) charging station going in anywhere - save, perhaps, the moon or Mars - won't be news.
But we're obviously not there yet.
