Currently, geothermal power plants operate in dozens of countries. The dominant position is that geothermal power plants are environmentally safe, but some environmental aspects need to be carefully considered in the future when designing new geothermal facilities. Brief information about geothermal power generation technologies is presented. The main ecological aspects of geothermal energy are studied: chemical pollution, thermal pollution, noise, geological processes. An important point is the discharge of geothermal coolant into water bodies and on the earth's surface. The geothermal coolant contains such chemical elements and compounds as Na, Ca, Li, As, Pb, CO, РќBO, HS.
