U.S. Geological Survey (USGS) maintains resourceful website with geothermal data
The U.S. Geological Survey maintains a website with great resources on geothermal energy potential in the United States, including data, maps, publications and more.
The U.S. Geological Survey under its Energy Resources programm has the mission to characterize and assess geothermal resources in the U.S. and work with the Department of Energy and other partners to advance the technologies applied to discover, characterize and utilize those resources.
Geothermal energy is a significant source of renewable electric power in the western United States and, with advances in exploration and development technologies, a potential source of a large fraction of baseload electric power for the entire country. The USGS Geothermal Resource Investigations Project is focused on advancing geothermal research through a better understanding of geothermal resources and the impacts of geothermal development. This is achieved by applying a wide range of research methods to characterize resource occurrences, perform monitoring, and develop resource assessments. The project team works closely with a number of external collaborators from federal and state agencies, academia and industry on projects throughout the US and internationally (provide link to map of field study areas).
On its website it provides a good overview on its activities, and research highlights.
Furthermore the website provides a large number of publications on various regions, resources etc., various geothermal data points, e.g. maps etc.
