Can a geothermal reservoir be depleted?
Since the earth’s heat is continuously radiated from within, geothermal energy is classified as renewable. Geothermal energy production can be sustained for decades and potentially even centuries. A geothermal reservoir may only be depleted if the resource is poorly managed and the production rates exceed the recharge rates, or if there is no reinjection of produced fluids for recharge. In a well-managed geothermal field, the resource can be sustained almost indefinitely.
