In regard to geothermal energy, California is "hot." This energy source, which literally means the "earth's heat," is found throughout California on public lands. The Obama Administration's emphasis on renewable energy development has translated into an increasing interest in geothermal leasing and exploration in California as well.
BLM is currently conducting environmental reviews of proposals to consider leasing near Coso Hot Springs in Inyo County and east of the Salton Sea in Imperial County. New exploration and development projects have also been proposed in the Truckhaven Geothermal Leasing Area in Imperial County and at Mammoth Lakes Geothermal Field in Mono county.
The Geysers field in Lake and Sonoma Counties produces 46 percent of the total royalties from federal geothermal leases in California with:
Other fields in production include Heber in Imperial County, Mammoth Lakes in Mono County, and Wendel-Amedee in Lassen County.
Activities on all federal geothermal leases are authorized by the BLM field offices; activities on leases in The Geysers, for example, are reviewed and authorized by the Ukiah Field Office.
Geothermal leases generated
approximately 3.75 billion kilowatt hours
enough for 375,000 people.
Inspection and enforcement responsibilities for federal geothermal leases in California is geographically divided into two zones - North and South. All operations on federal leases located in California north of Sacramento ( North Zone ) are inspected by personnel from the Ukiah Field Office, with assistance from personnel in the Eagle Lake Field Office . For operations on federal leases located south of Sacramento ( South Zone ), inspections are coordinated through the Ridgecrest Field Office , with assistance from both the Bishop and El Centro Field Offices.
