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 thank...

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 c...

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 is...

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's ...

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 ...

Back in November, SolaRoad launched a test bike path that generates energy through solar cells embedded in the concrete. It sounds like an outlandish idea, but it's apparently paying off very quickly. The company has revealed that its road has generated much more energy than expected -- it produce...

You don't have to wonder any longer as to what Tesla will unveil at its April 30th event -- the company just spoiled things in advance. In an email to investors, the company states that its shindig will reveal both a previously-teased battery for your home and a "very large," utility-oriented batt...

It's a fundamental principle of physics that when you use energy, say to run an electric car, some of it is lost. Companies have tried to overcome this by installing hardware that harvests this lost heat, most famously in regenerative braking. Goodyear is hoping to do a similar thing with tyres, d...

Pornhub thinks it has a sexier solution for the age old problem of a gadget running out of juice prematurely, and the secret is in the (hairy) palm of your hand. Say hello to the Wankband: a wearable that straps on to your forearm, capturing the energy from a spot of self-love and using it to char...

Apple makes much ado about using clean energy sources to power its buildings these days, and it just put its money where its mouth is... a lot of money. The company is investing a whopping $848 million in a First Solar plant in California's Monterey County that, according to Apple chief Tim Cook, ...

Scientists have spent a lot of time trying to lengthen battery life, but safety and thickness matter, too. Just ask Boeing about that first problem -- its 787 Dreamliner was grounded for months thanks to battery fires. However, a group of University of Michigan researchers may have found a way to ...

The deep frying process isn't just useful for livening up your food -- it might also be the ticket to better batteries in your mobile devices. South Korean researchers have created highly conductive, stable electrode materials by spraying graphene oxide droplets into a very hot blend of acid and o...

Don't be too quick to toss out the battery from that ancient laptop -- it might just be the key to powering homes in developing countries, and helping the environment in the process. IBM researchers have revealed UrJar, a device that turns old lithium-ion battery packs into rechargeable energy sou...
