The U.S. Geological Survey estimates that, in the United States alone, 30 gigawatts of undiscovered hydrothermal resource capacity and more than 100 gigawatts of EGS potential lie deep in the subsurface—equivalent to 10% of today's energy needs.

Geothermal Technologies Office

The Geothermal Technologies Office (GTO) supports research and development in innovative technologies that reduce the risk and costs of bringing geothermal power online, in partnership with industry, academia, and DOE's national laboratories. GTO invests in projects that establish geothermal energy as a core component and an economically competitive contributor to the U.S. energy supply.
