Wave power is the oft-forgotten cousin of solar and wind power. It has huge potential, but it is not quite as far along as the better known sources of clean power, so it tends to be overlooked. But it shouldn't! To clean up our power grid we'll need all the help we can get. Granted, in many places where wave power would work, offshore wind power would also work, but that might not be the case everywhere (ie. very deep water), and if wave power's cost can be brought down enough, that might not even matter.

Eager for jobs and tax money, Mojave Desert counties welcomed big solar projects. But they may have been too optimistic.

A unique airplane has just completed a 4,000-mile journey, making the first solar-powered intercontinental round-trip air journey. Traveling between Europe and Africa, the Solar Impulse experimental solar airplane landed in Payerne, Switzerland at 8:30 p.m. local time (2:30 p.m. ET) on Tuesday. The odyssey began two months ago, on May 24. This wasn't a test to see how fast the plane could make the trip, but to assess its endurance and reliability.

Solar panels prices have kept marching lower this year, extending steep declines seen in 2011 and keeping pressure on hard-hit manufacturers who have struggled to eke out profits, industry experts said.

Industry analysts and government auditors say the administration failed to take note of trouble already evident in the solar energy marketplace.

Leaders of a House subcommittee want to make the Obama administration answer for putting taxpayers on the hook for a half-billion-dollar loan to a now-bankrupt solar panel manufacturer. A hearing Wednesday will examine what went wrong ...

A California solar-panel manufacturer once touted by President Barack Obama as a beneficiary of his administration's economic policies -- and the recipient of a $535 million federal loan -- is laying off 1,100 workers and filing for bankruptcy.

NASA's upcoming mission to Jupiter can't get much greener than this: a solar-powered, windmill-shaped spacecraft....

General Electric says it's going to build the nation's largest solar panel factory, part of a $600 million dollar bet on the future of solar power in the United States.
