Low Maintenance
Both geothermal power plants and home heat pumps have low lifetime costs, since most of the equipment is underground and there are few moving parts. Most of any geothermal system is made up of pipes that transfer water from a heat source to power a turbine. Other than on the turbines, the wear and tear is minimal.
Low Pollution
Power plants using geothermal heat sources have zero emissions, compared with fossil fuel plants. No burning takes place during geothermal energy production and only steam is produced to power generators. Although small amounts of sulfides and other gases associated with volcanic activity may be released, they are at much lower levels, compared with traditional fossil fuels, and these emissions are easily mitigated by filtering systems.
Near Infinite Fuel Source
Areas with volcanic activity or warmer crust near the Earth's surface are constantly having their heat replenished at a rate much faster than can be exploited by geothermal power plants. As a result, they can practically never run out of fuel. The continuous decay of radioactive elements in the Earth's crust will continue to provide heat longer than fossil fuels.
