Some geothermal wells are as much as two miles deep. The hot water or steam powers a turbine that generates electricity.

People use these resources by drilling wells into the earth and then piping steam or hot water to the surface. Geothermal power plants require high-temperature (300Â☏ to 700Â☏) hydrothermal resources that come from either dry steam wells or from hot water wells.

Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal).

The global Geothermal Power market size was valued at USD 9756.38 million in 2022 and is expected to expand at a CAGR of 8.59% during the forecast period, reaching USD 15993.03 million by 2028.
