Energy Unearthed

Geothermal power generation uses the natural heat of the earth to make electricity for homes and businesses. In 2023, 4% of Berkshire Hathaway Energy’s owned renewable generation capacity came from geothermal energy.


BHE Renewables, operating as CalEnergy, owns and operates 10 facilities in California’s Imperial Valley that produce electricity solely from naturally occurring steam.


They do this with geothermal production wells that tap into superheated water reservoirs thousands of feet beneath the earth’s surface to release tremendous pressure, which rushes to the surface. Once above ground, the steam is separated and used to drive turbines that generate electricity.
4% of the renewable energy generated is provided by geothermal generators

Our Facilities


Berkshire Hathaway Energy has an interest in more than one dozen facilities across the U.S. that harness or produce geothermal power.

Geothermal Efficiency


Geothermal energy is so efficient, the only real source of energy loss comes from turbine friction.
