The development of fuel cell technology has been hamstrung by the need for expensive and difficult-to-manufacture catalysts like platinum, rhodium or palladium. But a team of researchers from the University of Wisconsin-Madison believe they've found an ingenious alternative that employs a molecula...

It's no longer safe to say that the Solar Impulse 2 aircraft will make it around the world before 2015 draws to a close. The crew is now warning that its sun-powered machine won't fly the next leg of its journey (from Hawaii to Arizona) for at least two to three weeks due to severe heat-related ba...

Sure, you can make solar-powered devices that store their excess energy in a battery, but what about the battery itself? Unfortunately, it's still behind the times -- the lithium-ion cells you see today have to be connected to another device to charge, and they're occasionally very dangerous than...

In the future, there's a good chance you'll see fewer wind farms being erected in the British countryside. That's because the UK government is killing a subsidy scheme that gives onshore wind farms a helping hand when they sell their electricity to energy suppliers. Under the Renewables Obligation...

Used to be that the only time your lithium-ion batteries changed their shape was when they were about to explode in an airliner cargo hold. But thanks to the ingenuity of an Arizona State University research team, future power packs could not only bend but stretch up to 150 percent of their origin...

Mercedes and Tesla aren't the only electric car makers giving their batteries something to do besides getting you from A to B. Nissan is teaming up with Green Charge Networks to repurpose "second-life" (read: used) batteries from Leaf EVs as commercial energy storage. Much like the batteries you...

Amazon has a reputation problem. While fellow tech giants like Apple and Yahoo are considered champions of clean energy, Greenpeace and other advocacy groups regularly knock Amazon for running its servers on dirty power (like coal) and saying little about its renewable energy plans. The company...

Guess what, Tesla: you're not the only car maker getting into the home battery game. Mercedes-Benz has unveiled a personal energy cell that, like Tesla's Powerwall, uses giant batteries to store surplus power from your home's solar panels and keep you off the conventional energy grid. The German f...

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'...

Scientists have long talked about black silicon (that is, silicon with nano-sized structures) having the potential to trump conventional solar power, and there's now some proof that this is happening. Aalto University researchers have developed black silicon solar cells that achieve a record 22.1...

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...
