geothermal maps

There are a number of excellent sites for obtaining maps of geothermal resources for your state and community.  These maps can help you understand the potential for using geothermal heating in your area.  All of the U.S. can make use of low temperature approaches to geothermal energy using geothermal heat pumps.  But some areas, particularly in the west and southwest, have as yet untapped potential for high temperature geothermal energy. 

Links to Geothermal Maps

Listed below are links to a variety of geothermal resource maps.  Many of these are provided by the U.S. government and can also be found at the U.S. Geothermal Technologies Program web site:
