How is geothermal energy typically harnessed for electricity generation?

  • Geothermal energy is used to heat water, which is then stored in a reservoir to generate electricity through thermal storage

  • Heat from the Earth is utilised to produce steam, which drives turbines connected to generators in geothermal power plants

  • Geothermal reservoirs are combined with wind turbines to generate hybrid electricity by converting both heat and wind energy

  • Water from geothermal reservoirs is pumped into hydroelectric dams to enhance electricity generation efficiency by using combined water flow
