What are 3 disadvantages of geothermal energy?

Disadvantages of Geothermal Energy

  • Geothermal energy has high initial capital costs.
  • May release harmful gases.
  • Suited to a particular region.
  • Geothermal heat pumps have to be powered.
  • Geothermal sites may experience a dry spell.
  • Sustainability issues.
  • Can cause surface instability.
  • Extremely high temperatures required.

Why is my electric bill so high with geothermal?

The system could be much more expensive if it’s colder outside and the heating set point is set much higher than it was with the propane system. Increasing the set point with geothermal is common. When dealing with propane, an expensive fuel source, homeowners will often set their homes to 65°F or less to save money.

What can go wrong with geothermal?
