After a briefly presentation of power generation from geothermal energy, this paper presents the binary power plant at the University of Oradea as an example of geothermal low- enthalpy utilization for power generation. The total worldwide installed electric power capacity exceeds 8 GW as far as geothermal sources are concerned. This installed capacity is not equally distributed around the world. The United States is first, followed by the Philippines, Mexico and Italy. Japan, New Zealand and El Salvador are others worth mentioning as places of geothermal electricity production. Certain geological locations provide high enthalpy resources that are best adapted for power production. These are the so-called plate boundaries which take the form of subduction zones, spreading zones, or rift zones
