Geothermal Resource Maps
Enhanced Geothermal Systems (EGS) will be able to access earth's heat throughout the United States. Technologies needed to effectively tap these resources depend on the amount of heat available at various depths from the surface. The relationship between temperature and depth is referred to as the heat gradient. On these pages, you'll find a variety of maps and data that identify geothermal resources around the world.
- Geothermal energy worldwide from the Geothermal Education Office.
- Geothermal Map of North America.
- Geothermal Resources of the United States from the DOE Energy Efficiency and Renewable Energy Office.
- Geothermal Resources of 13 Western U.S. States from the Idaho National Laboratory.
- Interactive maps and GIS regional spatial data of the geothermal energy potential of the Great Basin area from the Great Basin Center for Geothermal Energy.
- A virtual map of thermal springs developed by the National Geophysical Data Center and searchable online.
- Geothermal resources and projects suitable for low-temperature direct-use applications and potential collocated resources and communities from the Geo-Heat Center.
