geothermal power stations
A geothermal power plant uses it's geothermal activity to generate power. To harness the energy, deep holes are drilled into the earth (much like when drilling for oil) until a significant geothermal hot spot is found. When the heat source has been discovered, a pipe is attached deep down inside the hole, which allows hot steam from deep within the earths crust to rise up to the surface. The pressurized steam is then channeled into a turbine, which begins to turn under the large force of the steam. This turbine is linked to the generator and so the generator begins to also turn, generating electricity.
