Fast Facts about California Wind Energy

Wind energy projects totaling at least 5,454 megawatts (MW) of capacity are operating in California today,1 providing enough electricity to power more than 2 million California households.2 This represents more than a tripling of wind energy capacity since California's Renewables Portfolio Standard (RPS) law was adopted in 2002.

In 2017, California wind projects generated 13,500 gigawatt-hours (GWh) of electricity – 6.8% of all power generated within California.3 In 2016, out-of-state wind projects generated 12,822 GWh of electricity for California, representing  almost 14.0% of total power imports.3 Combined, wind projects supplied over 9% of California’s total system power,3 enough to power all homes in Sacramento, Santa Clara, and San Diego Counties combined.2

Wind energy accounted for 31% of California’s renewable energy production for the RPS as of 2017.4 (See figure below.)

Generating wind power creates no emissions and uses virtually no water:

  • The water consumption savings from wind projects in California total more than 3.4 billion gallons of water per year1
  • The wind power installed in California will avoid over 7.8 million metric tons of carbon dioxide emissions annually, the equivalent of taking 1.7 million cars off the road1
