Fast Facts About Wind Energy

map showing wind resource areas of california

Existing utility-scale wind power generation facilities can be found in five major resource areas in California:

Three of these primary regions (Altamont, Tehachapi and San Gorgonio) account for nearly 95 percent of all commercial wind power generation in California and approximately 11 percent of the world's wind-generated electricity (Source: Energy Commission, WPRS 2001-2002). With an average California household using 6,500 kWh of electricity per year, 3.5 billion kilowatt-hours (kWh) of annual electricity generation from wind resource in the state provides electricity sufficient to power over 530,000 homes.
