The United States has so many viable spots for producing geothermal energy — i.e. tapping into the heat of the Earth’s core to generate power — that the country's geothermal potential is equivalent to "10 times the amount of coal capacity in place today," according to Climate Progress.
Southern Methodist University developed this geothermal map in partnership with Google. The western half of the country has the greatest potential for geothermal development, but there are hot spots elsewhere — check out that orange spot in the Northeast. That's in coal country and provides a way to keep jobs while shutting down dirty coal mines and power plants.
