geothermal energy

Map of the United States color-coded to show the distribution and favorability of deep enhanced geothermal systems (EGS) resources. Red and orange areas in the western states indicate the most favorable regions for geothermal energy, while yellow and light green areas in the central and eastern U.S. show less favorable or unassessed regions. Some areas are marked with gray for no data.
