- Water is pumped into the earth and then gets pumped out causing the water to turn into steam. The steam rotates a turbine that activates a generator, which produces electricity. Many power plants still use fossil fuels to boil water for steam. Geothermal power plants, however, use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface.
- Geothermal heating system price varies depending on the type of loop system, usually either vertical or horizontal. On average, a typical home of 2500 square feet, with a heating load of 60,000 BTU and a cooling load of 60,000 BTU will cost between$20,000 to $25,000 to install.
- Benefits of this system are
- it cost less than a lot of other sources
- it is renewable.
- the effects are reversible
- it can be in any place that has geothermal potential.
- Faults in the system
- geothermal energy sources can be unstable
- it can poison water near it
- The cost is the same as a new car
