Geothermal heating systems take heat from the ground and transfer it to your St. Maries home. But how does this heat get into the ground in the first place? Conventional heating systems like furnaces use energy sources like oil or natural gas to generate heat. These energy sources are not renewable, and neither is electricity which is typically generated by burning coal or another non-renewable resource.
The renewable resources we usually think of first are solar and wind power. The sun, of course, will continue to shine and provide heat year in and year out whether we make use of it or not. Similarly, we cannot use up the wind. It will continue to blow no matter how many times it has blown before.
But what category does geothermal energy fit into exactly? Well, it is actually a renewable resource just like solar or wind energy. In fact, geothermal energy is a direct result of the sun’s heat relentlessly pounding the ground. The ground actually absorbs a considerable amount of the heat from the sun that reaches the earth every day, and that is the heat that your geothermal heating system is using to heat your home.
Of course, a geothermal heating system cannot run on geothermal energy alone. The indoor components of this heating system that keep the air flowing throughout your house must be powered by electricity. But the amount of energy needed to do this is much less than what you would need to use to run a furnace or other type of more conventional home heating system.
Over all, geothermal energy is an excellent and renewable source of energy. And once you have the heating system in place, you will need to spend very little to keep it up and running. It is an excellent option for many people, and can help to keep your home cool in the summer as well.
