What is geothermal energy all about?
A geothermal system is a heating and cooling unit designed to extract the natural heat stored in the ground during the winter and discharge heat from air conditioning to the relatively cool ground in the summer. A geothermal system can also heat water. The sun shining on the earth warms the ground to maintain a relatively constant temperature of about 52 degrees Fahrenheit year round in northeast Ohio at a depth of 4 to 6 feet.
