Superhot Rock Geothermal in California

The document highlights superhot rock geothermal as a high-density, zero-emission energy source that could significantly exceed California's current electricity needs while utilizing existing oil and gas sector expertise.

• Preliminary modeling indicates that just 1% of California's superhot rock geothermal resource could provide 379 GW of energy capacity, generating over 3,158,010 GWh of electricity, which is 13 times the state's 2023 electricity consumption of 239,480 GWh.
• Superhot rock geothermal is characterized as an energy-dense resource with significantly lower land requirements than other energy sources; producing 1 GW requires approximately 12 sq mi of land, compared to 160 sq mi for natural gas, 180 sq mi for solar, 520 sq mi for offshore wind, and 14,000 sq mi for biomass.
