Map of geothermal power generation in each state

Screenshot of NREL's map of installed geothermal power capacity in each U.S. state as of February 2015

The National Renewable Energy Laboratory's (NREL) map of current and planned geothermal power production by state shows the nameplate capacity, the maximum manufacturer-rated output of a generator in megawatts, for geothermal energy in each state as of February 2015 (for more detailed and up-to-date information on geothermal energy development in the U.S., visit NREL's Geothermal Prospector web app). The numbers in white show the current installed capacity, while the numbers in yellow show the planned additions.
