Geothermal power implies electricity. We use geothermal in three ways depending on the temperature of the geothermal resource (which is usually fluids or water). So the highest temperature is what we call geothermal power, which is used to make electricity. The second level is what we call direct use, which is intermediate temperatures where we use the resource directly for heat. Then the third level would be a low temperature, which is for heat pumps. Geothermal heat pumps are efficient because we take usually one unit of electricity to make about 3-4 units of heat. So they work like a refrigerator.
