Are geothermal power plants bad for the environment?
When geothermal power plants do emit gases, it’s mostly carbon dioxide, which isn’t a pollutant but a greenhouse gas. Still, geothermal power plants emit much less carbon dioxide than fossil fuel power plants.
What gases are emitted from geothermal power plants?
They emit little carbon dioxide, very low amounts of sulfur dioxide, and no nitrogen oxides. See Charts 1, 2, and 3 below. The small quantities of gases emitted from geothermal power plants aren’t created during power production because there’s no combustion. These gases are natural, minor constituents of all geothermal reservoirs.
Do geothermal power plants emit more carbon dioxide than fossil fuels?
Still, geothermal power plants emit much less carbon dioxide than fossil fuel power plants. Also, the common practice by geothermal power plants to inject geothermal fluids back into reservoirs to sustain resources has diminished their carbon dioxide emissions.
How does geothermal energy help the environment?
Most geothermal power plants inject the geothermal steam and water that they use back into the earth. This recycling helps to renew the geothermal resource and to reduce emissions from the geothermal power plants. Geothermal features in national parks, such as geysers and fumaroles in Yellowstone National Park, are protected by law.
