This surprises me. See: http://www.renewableenergyworld.com/rea/news/article/2013/02/us-solar-projects-will-eclipse-wind-this-year-says-duke
Quote: "The U.S. may install 3 gigawatts to 4 gigawatts of wind turbines this year, and solar projects will probably exceed that, said Gregory Wolf, president of Duke Energy Renewables. The U.S. added 13.1 gigawatts of wind power last year, beating natural gas for the first time. U.S. wind projects have come to a near-standstill this year on uncertainty over the fate of a federal tax credit that was set to expire Dec. 31. . . ." - Jed
