One chart shows how solar energy growth is skyrocketing compared to predictions
In early 2016, the International Energy Agency (IEA) projected that, starting that year, the world would add just 50 gigawatts of added solar energy capacity per year. And in 2017, solar's growth rate would level out and start to decline. But as one clean energy researcher points out, the Read More...
The top 10 states leading the renewable energy revolution in the U.S.
California remains the U.S.’ renewable energy leader, but energy efficiency and renewables are gaining major ground across the country, a new ranking of states and cities shows. Six states now get at least a fifth of their power from non-hydro renewable sources such as wind and solar. The Read More...
