Question

How is geo thermal energy converted into useful work? ​

Answer 1

Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity

Answer 2

Geothermal energy is converted into useful work by using a heat exchanger to capture the heat energy from the Earth's core and convert it into steam. The steam is then used to drive a turbine, which in turn produces electricity. In some cases, the steam is used to directly heat buildings or water, bypassing the electricity-generating process. In either case, the thermal energy is converted into useful work.
