All Geothermal Applications
Maintained by the Geo-Heat Center, this interactive map and database provides summary information on geothermal power plants and direct use projects, which are divided into the following categories: space heating, district heating, industrial, greenhouses, aquaculture, spas and pools, agricultural drying, and snow melting. Information can be viewed by state or by application.
Provided by the Geothermal Energy Association, this site has a comprehensive list of geothermal plants by state and includes data, contact information, and a small photograph of each plant. The information is more detailed than that provided by the Geo-Heat Center map and database, above.
