The Largest Geothermal Power Stations in the World
Geothermal power stations are similar to other steam turbine thermal power stations in that heat from a fuel source is used to heat water. The water then rotates a generator’s turbine to produce electricity.
It uses hydrothermal resources that have water (hydro) and heat (thermal). Geothermal power plants require high temperature (300°F to 700°F) hydrothermal resources from either dry steam wells or hot water wells.
Geothermal energy is renewable energy taken from the Earth’s core. It comes from the heat generated during the planet’s initial formation and materials’ radioactive decay.
This thermal energy is kept in rocks and fluids in the Earth’s center.
