Geothermal power station, illustration. Geothermal power systems harness the energy in water and steam that have been heated naturally within the Earth's crust. The power is used to generate electricity, as here, with cold water pumped down into the Earth (centre right, blue) and back up again (lower left, red) as hot water or steam. The heated water is used to drive the turbines (centre) that generate electricity that is distributed through wires on pylons (upper left). | |
