The geothermal resources are reservoirs of hot water on different depths below the Earth's surface. The deep wells are drilled into underground reservoirs for bringing the hot steam to the surface for the use of electricity generation. Residual heat can be used for heating greenhouses, houses, schools, business premises, etc.
Geothermal power plants produce electricity consistently, running 24 hours per day / 7 days per week, regardless of weather conditions. No need for importing LNG, coal or diesel, if you produce your own energy. The footprint of a geothermal power plant is very small, using less land per GWh than wind, solar PV with centre station or coal.
Uses of geothermal
Geothermal energy can be used for electricity production or for commercial, industrial and residential direct heating purposes. In fact, the Romans used geothermal water to treat eye and skin diseases, at Pompeii, and to heat buildings. They were true pioneers.
