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

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

One of the biggest challenges of switching to clean energy sources is finding a place to store excess power. That's relatively easy on a small scale, but it's much more daunting for your utility company. Southern California Edison is apparently ready to take on that challenge, however. It just lau

The United Arab Emirates' pre-planned Masdar City is supposed to be a shining beacon of technology between its clean energy and automated cars. However, it has hit a few roadblocks, including the financial crisis from the last decade -- and the result is less of a Utopia and more of a ghost town.

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

Forget lab-made materials like graphene -- natural, old-fashioned hemp may be the ticket to our energy future. Researchers have demonstrated that you can make very efficient carbon electrodes simply by heating hemp bast fibers in a two-stage process. The resulting substance holds as much energy

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

Cyberwarfare campaigns against Western energy grids aren't just the stuff of action movies these days -- they're very, very real. Symantec has discovered a likely state-sponsored hacking group, nicknamed Dragonfly, that has been using phishing sites and trojans to compromise energy suppliers in t
