Wind power in the United States
Wind power in California has doubled in capacity since 2002. With a total of nearly 4,000 megawatts installed, as of the end of 2011, wind energy now supplies about 5% of California’s total electric power needs, or enough to power more than 400,000 households. The amount varies greatly from day to day. In 2011, 921.3 megawatts were installed. Most of that activity occurred in the Tehachapi area of Kern County, with some big projects in Solano, Contra Costa and Riverside counties as well. After 2014, California ranked second nationwide in terms of capacity, behind Texas with a capacity of 5,917 MW.
