Yes, like all the other sources of green energy. Geothermal plants don’t produce greenhouse gases, unlike conventional power plants that use fossil fuels like coal, oil, or gas. Even though there might be some gas emissions from the ground (95% of which is carbon dioxide mixed into geothermal fluids), today’s technology makes it possible to contain the vast majority of these substances, preventing them from being released in the atmosphere. According to a European Union report, every kilowatt-hour of geothermal energy saves 260 grams of CO2 compared to a gas-fired plant, 705 grams compared to an oil plant, and 860 grams compared to a coal-fired plant. The International Energy Agency (IEA) calculated that 92 terawatt-hours of geothermal energy were produced worldwide in 2019; moreover, in the United States alone, geothermal plants are estimated to avoid the emission of greenhouse gases equal to 4.1 million tons of carbon dioxide a year.
