The Geysers is the world's largest geothermal field, containing a complex of 18 geothermal power plants, drawing steam from more than 350 wells, located in the Mayacamas Mountains approximately 72 miles (116 km) north of San Francisco, California. Geysers produced about 20% of California's renewable energy in 2019. Calpine, the largest generator of electricity from natural gas and geothermal resources in the US, generates power at the site.
