The United States of America is being the top country by geothermal electricity net generation in the world. As of 2014, geothermal electricity net generation in the United States of America was 15.88 billion kilowatthours that accounts for 21.29 % of the world's geothermal electricity net generation. The top 5 countries (others are Philippines, Indonesia, New Zealand, and Mexico) account for 66.37 % of it. The world's total geothermal electricity net generation was estimated at 74.56 billion kilowatthours in 2014.
The amount of gross generation less the electrical energy consumed at the generating station(s) for station service or auxiliaries. Electricity required for pumping at pumped-storage plants is regarded as electricity for station service and is deducted from gross generation. Geothermal plant is a plant in which the prime mover is a steam turbine. The turbine is driven either by steam produced from hot water or by natural steam that derives its energy from heat found in rock.
