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'...

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...

There's no doubting that the cause of renewable energy is a noble one. But, ethics aside, it also gives birth to the occasional technical marvel. Altaeros Energies, a company from Massachusetts (with MIT and Harvard blood in its veins) has created one such curiosity. The prototype is a wind-turbi...

Building and putting any sort of offshore wind turbine into place is a fairly impressive bit of engineering, but Denmark's Vestas is truly going the extra mile with its new V164-7.0 MW turbine. Not only does it promise to provide seven megawatts of power but, as you can see above, each of the blade...

Why just use solar power or wind power when you can use both? Designed by Francesco Colarossi, Giovanna Saracino and Luisa Saracino as part of an Italian design contest to re-imagine a decommissioned bridge (for which it placed second), this so-called Solar Wind concept would have solar cells embed...
