Geothermal Energy

Harnessing the Earth's heat
eothermal energy harnesses the heat from the Earth's interior to generate electricity through steam from hot water reservoirs located deep below the Earth's surface that turn turbines and generate electricity. One of the main benefits of geothermal energy is that it is a clean and sustainable source of power that does not produce any greenhouse gas emissions.
Geothermal capacity While theoretically, geothermal energy can provide the entire energy needs of the world, the actual installed capcity worldwide stands at close to 70GWh (about 8% of eglobal energy use, covering 17% of the world's population). Geothermal energy provides a large proportion of energy for celand, El Salvador, New Zealand, Kenya, and Philippines.
Geothermal energy is generated by using heat from beneath the Earth's surface, particularly in volcanically active areas. Super-heated steam drawn from below Earth is used to drive turbines that generate electricity.
