Despite their giant blades, most wind turbines waste a lot of energy -- gusts around the rotor don't really generate electricity at all. GE thinks it can do better, however. Its experimental ecoROTR turbine touts a big, rotating aluminum nose that sends wind directly toward the blades, where it'...

It may be tough to satisfy the US' seemingly never-ending thirst for energy, but clean power sources are at least helping to soften the impact. Researchers at the Lawrence Livermore National Laboratory have determined that Americans' energy use climbed 1 percent year-over-year in 2014, but its car...

Sunset Park in Brooklyn is home to New York City's first commercial-scale wind turbine, and it's already flexing its green muscle. In under a month, the 160-foot-tall power source produced enough juice to power two homes for more than 12 months. It's not being used to supplement regular energy use...

For the most part, portable energy generators are intended for modest uses. They can charge your phone, but they won't drive high-powered laptops or small appliances. That might change if Omni3D gets its crowdfunded AirEnergy 3D off the ground. The 3D-printed wind turbine should fit into a backpac...

Many green energy sources only generate power in a narrow range of conditions. Solar panels won't work when it's dark, for instance, and wind turbines are useless when everything is still. If Solar Wind Energy Tower has its way, though, we'll soon get clean electricity around the clock. It recentl...

Google's goal of meeting its electrical needs with renewable sources got another big boost today. The Happy Hereford wind farm in Texas will produce 240 megawatts of juice, and all of that output has been bought by Big G. That power won't flow directly from the turbines into Google's data centers,...
