Geothermal Resource Information
The Hot Springs Lodge and Pool in Glenwood Springs, Colorado, uses a geothermal heat exchanger system with its hot surface spring to provide space heating, domestic hot water, and snow melting.
Access to a host of geothermal resource maps is provided by the US Department of Energy's Office of Energy Efficiency and Renewable Energy Geothermal Technologies Program. Its collection includes general resource maps as well as maps of existing geothermal projects, subterranean temperatures, and thermal springs.
