Solar farms need three things: sunlight, photovoltaic panels and a huge expanse of land.

Let it not be said that public parks are anti-technology. Over in Boston, city officials are more than happy to try new things in green spaces, including the use of solar-powered smart benches, aka "soofas." These look a lot like regular benches, except they're equipped with big, steel-encased blo...

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...

When I showed Sol to my family, they all got a bit confused. My dad asked why I was testing a toolbox for Engadget, while my sister took one look at it and said "Bumblebee." If you peek at the images below, you'll understand why: This solar-powered laptop does resemble a hardware tool case. And ye...
