Geothermal energy is a renewable source since the Earth endlessly generates heat at its
core through radioactive decay. Even though geothermal power generation usually depends on
a reservoir of hot water or steam (i.e., geothermal fluid), the volume extracted can be reinjected,
making its exploitation sustainable when appropriately managed.
CON |
In some individual reservoirs, pressure has dropped (or resources have become depleted)
due to an unsustainably high withdrawal rate and/or failure to reinject the used geothermal fluid.
Addressing problems associated with inadequate reinjection practices can be complex and costly.

Utilization of geothermal power instead of fossil fuels, such as oil, gas, coal, etc., can
reduce emissions of CO
2
and local air pollutants to low, often negligible levels per unit of energy
produced.
