- Geothermal energy is generated by drilling wells into high-temperature water or “hot rock” reservoirs and using the hot water or steam to turn a turbine.
- Geothermal energy has the smallest land surface footprint of any renewable energy source, aside from nuclear power emissions.
- Electricity generation by geothermal energy does not produce significant carbon dioxide.
- Potential environmental threats from heavy metal contamination must be considered and mitigated.
