Dec 11, 2013 — California plans to get 33 percent of its electricity from wind and solar power by 2020. But that will only work if the state can economically store some of the energy for release on cloudy, windless days.
Dec 5, 2013 — Under the new plan, each federal agency would have until 2020 to get 20 percent of its power from renewable sources such as solar and wind.
Nov 30, 2013 — Renewable energy has become a $220 billion a year industry. But to significantly slow climate change, the power of wind, solar and other renewable sources must vastly expand. Some say the tech breakthroughs needed are on the horizon, though a top economist sees a tougher road ahead.
