Geothermal: Sustainability & Issues
Renewable Energy

Geothermal energy is a clean, safe, and an environmentally friendly energy source. As long as the earth surface is hot it is renewable. This creates a steady amount of energy from that area. However, studies have shown that these hot areas do cool down, making long term sustainablity questionable.

Geothermal cannot be used on a large energy production scale outside of the Western United States. Construction can adverse affects on land stability. Enhanced Geothermal systems work by putting water into the ground where water was not located before. The effects of doing this is unknown. Geothermal is clean but does produce 5 percent of what fossil fuel plants do.
