U.S. Department of Energy - Energy Efficiency and Renewable Energy
Geothermal Technologies Office
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.
