Blazing The Trail For New Geothermal Production
The Energy Department helps develop and deploy geothermal energy technologies that advance hydrothermal power production (pictured) -- where fluid flow and hot rock occur naturally -- and enhanced geothermal systems (EGS) technologies -- where fluid is injected into deep, hot rock formations to create a geothermal reservoir. The U.S. Geological Survey estimates there’s 30 gigawatts of undiscovered hydrothermal resource capacity and more than 100 gigawatts of enhanced geothermal potential, equivalent to 10 percent of today's energy needs.
