Geothermal Maps

Map of the United States, with color bands indicating favorability of deep EGS and dots indicating identified hydrothermal sites.

Resource potential for United States, including identified hydrothermal sites and favorability of deep enhanced geothermal systems (EGS), produced by National Renewable Energy Laboratory in conjunction with GTO.

The Geothermal Technologies Office (GTO) carries out R&D and demonstration efforts to deploy 12 GWe of clean geothermal energy by 2020 and expand geothermal into new U.S. regions.

Locating and developing resources is an important part of that mission. GTO works with national laboratories to develop maps and data that identify renewable, geothermal resources, possible locations for implementation of various geothermal technologies, and actual and potential geothermal power generation sites.

The maps below were developed by National Laboratories, universities and other organizations.
