Abstract

Geothermal energy is the natural heat of the ground and involves accumulated heat in fluids and granite rocks. Geothermal energy can be used to generate electric and heat energy. In the first case it is a marginal source of energy, which can be used only in limited number of locations. In the second case, it is a geothermal energy with low enthalpy values, which is based on the use of the natural heat of the ground using the heat pumps. Process of acceptance the technologies that use the geothermal energy is very slow and the main problem is high price of installation the new plant. This paper presents some of technologies, based on the use of geothermal energy, as well as the investment and exploitation costs of plants whose operation is based on the use this form of energy.

Keywords

geothermal energy; geothermal power plant; heat pump; costs
