Journal: Thermal Engineering
Year: 2020

Geothermal heat supply occupies the second place among the renewable energy sources around the world in installed capacity (70.3 GW) and in the amount of generated thermal energy (163 (TW h)/year). It is outperformed only by solar heat supply (480 GW and 395 (TW h)/year). The use of geothermal heat involves the need to drill wells and fulfill special requirements for development of geothermal fields and construction of heat-supply systems. There are deep (more than 400-m deep) and shallow geothe
