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 as...

These days, data centers, portable USB battery chargers and all sorts of transportation are going green thanks to fuel cell technology. Now you can add submersibles to that list: Japan is developing a 33-foot-long submarine that runs off emissions-free energy. Japanese Defense Ministry officials t...

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 th...

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...
