What is Geothermal Energy, and What are the Benefits?

Geothermal energy is a natural energy that comes from the hot rocks inside the earth, deep below the surface. To harness this energy, two holes are dug into the ground, one for water to be pumped through. As the water passes the hot rocks, it is transformed to steam, which comes out of the second hole and aids in producing electricity. The heat exchanger only uses electricity to move the heat, not produce it.

In Michigan, the temperature in the earth just a few feet below the surface remains at a 50-55 degrees Fahrenheit. So in winter, geothermal energy can be used to heat as tCapturehe earth temperature is warmer than the air, and in the summer geothermal energy can be used to cool as the earth temperature is colder than the air. To switch from heating to cooling, all you have to do is reverse the flow and temperature compression.

Benefits of Utilizing Geothermal Energy

  • The energy is renewable and sustainable, replenishing itself naturally. Plus, it’s not going to run out in any foreseeable future.
  • Reduce your footprint. Using geothermal energy is a clean and environmentally-friendly process. It does not create pollution.
  • According to the US Environment Protection Agency, the systems are “the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available today.”
  • Save money on heating and cooling bills as geothermal energy is extremely efficient. Customers have reported saving about 80% on utility bills after installing a geothermal energy system.

Depending on your land, there are a few different options for geothermal energy systems. The traditional system is a horizontal loop which resides in trenches three to six feet deep and is a closed loop system. This system requires more space, however, so in limited spaces you would need a vertical loop: pipes are inserted in small holes 150 to 400 feet deep. For this, you will need a well-drilling rig. The third type of loop is a pond loop, where sealed spiral piping is actually submerged into the pond water instead of into the ground. And finally, if you have adequate quantity and quality, you can use a well water system which uses the supply of well water.

The only foreseeable downsides to choosing the geothermal energy system are that it may not be suitable for all locations and it can be more expensive for the initial cost than other heating and cooling systems—but in the long run it will save on costs.
