What is Geothermal Energy?

There are two types of geothermal energy: high grade and low-grade. High-grade geothermal energy is the heat of the earth’s pressure that turns water into stream. Old Faithful at Yellow Stone National Park is an excellent example. Low-grade geothermal energy is the heat within the earth’s crust. This heat is actually stored solar energy. S&B Geothermal sells and installs ground source heat pump systems that tap into this low-grade geothermal energy to deliver significant energy savings when heating, cooling and making hot water.
