The Future of Solar

A new thermochemical system is able to store energy from concentrated solar power plants indefinitely and then release it at record efficiency, in what could be an important step toward a greener energy grid.

When discussing potential ways to slow climate change, two of the ideas that are almost always presented are use of alternative energy sources and the preservat

Solar arrays are the unsung heroes of the International Space Station, drawing power from the sun to create an oasis of warmth and safety in the vast darkness of space.

The Department of Energy is urging children to dress up as solar panels and wind turbines for Halloween in a green initiative it’s dubbing “Energyween.”

A Pittsburgh project is designed to light up a disadvantaged neighborhood and show an alternative-energy future in a coal state.

And it's only going to get bigger as the solar panel industry grows.

And that's before any tax credits are accounted for.

Land Art Generator calculates the number of solar panels needed to provide renewable energy to the entire Earth. Currently, only 0.39 percent of the overall energy in the U.S. comes from solar energy.

The hotter solar cells become, the less efficient they are at converting sunlight to electricity, a problem that has long vexed the solar industry. Now, Stanford engineers have developed a transparent overlay that increases efficiency by cooling the cells even in full sunlight.
