What is the principle of geothermal energy production?

They all use the thermal energy of the steam to convert it into mechanical energy in the steam turbine, and then drive the generator to produce electricity. The difference is that geothermal power generation does not require huge boilers like thermal power generation, nor does it require fuel consumption. The energy it uses is geothermal energy. Energy experts believe that environmentally friendly geothermal energy production will have strong development prospects in the future. Some experts even estimate that geothermal energy production will represent 10% of total global electricity production in 20 years. China is rich in geothermal resources and has broad prospects in geothermal energy production.
