Geothermal energy in the u.s.
Geothermal energy currently provides more than 2,700 megawatts of electricity nationwide - the equivalent of three nuclear power plants, or enough to power more than 3.5 million homes.
A geothermal power plant emits no nitrogen oxides, very few sulfur dioxides and 1,000 to 2,000 times less carbon dioxide than a fossil fuel plant.
