The U.S. Geological Survey released the first national geothermal resource estimate in more than 30 years.
The results of this assessment show that the United States has an estimated 9,057 Megawatts-electric (MWe) of power generation potential from domestic, conventional, identified geothermal systems, 30,033 MWe of power generation potential from conventional, undiscovered geothermal resources, and 517,800 MWe of power generation potential from unconventional (high temperature, low permeability) Enhanced Geothermal Systems (EGS) resources.
Arizona is shown as having only 0.29% of the currently identified geothermal assessments, 3.47% of the unknown resources, and 10.56% of the enhanced geothermal resource potential identified.
