Like coal, gas or nuclear power facilities, a geothermal power plant converts heat to electricity. It does this using high-temperature (300°F to 700°F) heat – known as geothermal energy – from the Earth, accessed by drilling hot water or dry steam wells in a process similar to drilling for oil.

These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.

Geothermal energy is heat from the Earth. It is a renewable energy source with multiple applications including heating, drying and electricity generation.

Technically speaking, geothermal energy is regarded as a renewable source of energy which can produce energy for as long as our planet exists.

There are many advantages of geothermal energy but also some challenges that need to be overcome in order to fully exploit this natural resource.
