Geothermal Energy

Geothermal energy is heat from the earth. Its clean. Geothermal sources range from shallow ground and hot water to hot rock a few miles below the earths surface and even farther down to the magma.

A geothermal pump system pumps the heat into the air delivery system during the winter and does the reverse in the summer. Geothermal is used to heat and cool things such as buildings or machines and generate electricity.

  • Available everywhere


  • Can release hydrogen sulfide
  • Disposal of geothermal fluids which may contain low levels of toxic materials
  • In extreme cases can cause earthquakes
  • Very costly: $3000-$5000
