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

There are certainly clothes and wires that can transmit electricity, but wouldn't it make sense if they could hold on to it as well? Researchers at the University of Central Florida certainly think so, since they've just developed technology that lets wires and threads store energy. Their approach

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

Many green energy sources only generate power in a narrow range of conditions. Solar panels won't work when it's dark, for instance, and wind turbines are useless when everything is still. If Solar Wind Energy Tower has its way, though, we'll soon get clean electricity around the clock. It recentl

If there's one thing you should know about Engadget, it's that we absolutely love lasers. And thanks to the University of Arizona and University of Central Florida, our favorite pulsating form of light might soon find a much less destructive purpose, than say on Navy ships, anti-missile airliners

In many ways, plants are ideal technology hosts -- they're outdoor-friendly, self-healing and pollution-free. It only makes sense, then, that MIT scientists want to harness that potential by augmenting our leafy friends with nanotechnology. The researchers have found that injecting nanoparticles

Pacemakers and other electronic implants are a pain to keep running -- patients need surgery to replace batteries, and body-powered generators aren't currently strong enough to charge these devices. They may be far more practical in the future, though, as American and Chinese researchers have deve

Google's goal of meeting its electrical needs with renewable sources got another big boost today. The Happy Hereford wind farm in Texas will produce 240 megawatts of juice, and all of that output has been bought by Big G. That power won't flow directly from the turbines into Google's data centers,

Compressed air batteries have long promised truly clean energy storage, but they haven't scaled large enough in recent years to be viable companions to renewable power sources. That changes now that SustainX has switched on the first modern air battery large enough to join an electrical grid. The

As clever as the Nest Learning Thermostat can be, its intelligence only extends as far as the front door: it hasn't really been aware of how neighbors or the seasons affect our power bills. Nest Labs is improving that connection to the outside world through Nest Energy Services, a new program that
