|A source of renewable energy.||Gases are released into the atmosphere during digging.|
What are 2 disadvantages bad things of geothermal energy?
Geothermal Energy Disadvantages
- Potential emissions – Greenhouse gas below Earth’s surface can potentially migrate to the surface and into the atmosphere. …
- Surface Instability – Construction of geothermal power plants can affect the stability of land.
Is geothermal really worth it?
Due to their high price point, geothermal systems often take many years to recover the initial cost, but they are a worthwhile investment for environmentally-conscious and homeowners who plan to be in their homes for many years.
What is better solar or geothermal?
