Solar power just hit one of its biggest milestones, in more ways than one. First Solar recently finished building Topaz, a 550-megawatt plant that represents the largest active solar farm on the planet. And we do mean large -- the installation's nine million solar panels cover 9.5 square miles of

Solar power cells need to stay relatively cool for the sake of both efficiency and longevity, but active cooling (like ventilation) isn't practical; it's expensive, and may block the very rays the cells are supposed to collect. To tackle this problem, Stanford University researchers have created a

Renewable energy is getting better all the time, but no-one's yet worked out a good way to store the juice for those cloudy, windless days. Batteries do work, but given the high cost of swapping out the cells for your EV, we doubt that Duracell will start making a five-megawatt version any time so

Right now, you can install relatively cheap technology on your own roof and power your house, gadgets and even your car. For free! Sorcery? Not so much. The Earth receives more energy from our sun in about one hour than humans consume in an entire year. That's why solar power was the second leadin

Solar panels have become cheaper and more efficient in recent years, but you can't say the same for the big, costly inverters turning their energy into usable electricity. Google isn't happy with this lack of progress, so it's about to launch the Little Box Challenge, an open competition to build

Drive west on US Route 50 through a stretch of Nevada highway known as \"The Loneliest Road in America\" and you'll eventually find yourself in the rural county of Churchill. Once a solitary leg in the Pony Express route, irrigation transformed swaths of Churchill's high desert areas into thriving a
