Geothermal electricity generated from geothermal energy. Technologies in use include; dry steam power plants, flash steam power plants, and binary cycle power plants. Geothermal power plants do not burn fuel to generate electricity, therefore their emission levels are very low. They release less than 1% of the carbon dioxide emissions of a fossil fuel plant. Geothermal plants use scrubber systems to clean the air of hydrogen sulfide that is naturally found in the steam and hot water. Geothermal plants emit 97% less acid rain-causing sulfur compounds than are emitted by fossil fuel plants. After the steam and water from a geothermal reservoir have been used, they are injected back into the Earth.
