Geothermal Maps

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.

Maps by Energy Type or Measurement

• Direct-use projects in the United States – Geo-Heat Center, Oregon Institute of Technology
• 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
• Temperature and depth of U.S. geothermal resources – Google.org, using Google Earth
• Temperature at depth with sediment thickness for continental United States, produced by Idaho National Laboratory in conjunction with GTO with data from Southern Methodist University Geothermal Laboratory
• Thermal springs in the United States – National Geophysical Data Center
