what does a geothermal power plant do
Geothermal power stations are similar to other steam turbine thermal power stations â heat from a fuel source (in geothermal's case, the earth's core) is used to heat water or another working fluid. The working fluid is then used to turn a turbine of a generator, thereby producing electricity.eothermal power stations are similar to other steam turbine thermal power stations â heat from a fuel source (in geothermal's case, the earth's core) is used to heat water or another working fluid.
