Geothermal_Potential

Geothermal potential (Enhanced Geothermal System EGS) for the U.S. based on Levelized Cost of Electricity, with CLASS 1 being most favorable, and CLASS 5 being least favorable. Shallow EGS resources located near hydrothermal sites or USGS assessment of undiscovered hydrothermal resources are not included. CLASS 999 regions have temperatures less than 150° C at 10 km depth and were not assessed for deep EGS potential. Temperature at depth data for deep EGS in Alaska and Hawaii not available.
