Scientific American: “The amount of solar photovoltaics harnessing electricity from sunshine in the U.S. will more than double by 2013, thanks to plans to build 800 megawatts worth in California. The two vast solar farms—covering more than 12 square miles—will be among the largest ever built in the world and dwarf the current U.S. record holder: Nellis Air Force Base in Nevada with 14 megawatts. In fact, the total amount of solar photovoltaics connected to the grid in the entire U.S. is just 473 megawatts at present.”
