http://www.bloomberg.com/news/articles/2015-05-26/solar-as-fastest-growing-u-s-power-source-rivals-shale-boomMove over, shale. The sun is now the fastest-growing source of U.S. electricity. Solar power capacity in the U.S. has jumped 20-fold since 2008 as companies including Apple Inc. use it to reduce their carbon footprints. Rooftop panels are sprouting on homes from suburban New York to Phoenix, driven by suppliers such as SolarCity Corp. and NRG Energy Inc. Giant farms of photovoltaic panels, including Warren Buffett’s Topaz array in California, are changing power flows in the electrical grid, challenging hydro and conventional generators and creating negative prices on sunny days. The surge comes after shale drilling opened new supplies of natural gas, contributing to the 47 percent drop in oil since June. “Solar is the new shale,” Michael Blaha, principal analyst of North American power at Wood Mackenzie Ltd. in Houston, said April 8. “Shale has lowered cost and enabled lower natural gas prices. Solar will lower costs for electricity.”
Solar capacity surged 30 percent in 2014 to more than 20 gigawatts and will more than double by the end of 2016, according to the Washington-based Solar Energy Industries Association. That’s enough to power 7.6 million U.S. homes, up from 360,000 in 2009. The biggest gains will be in California, Arizona, Texas, Georgia, New York and New Jersey. In Germany, Europe’s biggest power market, solar power output gained 14 percent last year.
