5. Why is geothermal energy not always a renewable energy source?

—·Geothermal energy isn't always a renewable energy source because reservoirs can be depleted of the fluid is removed faster than replaced and will take a lot of effort on injecting the fluid back to the reservoir after the thermal energy has been utilized.
