A Cleaner, More Cost-Effective Resource
Studies show that approximately 70% of the energy used in geothermal systems is renewable energy from the ground. The remainder is clean electrical energy, which is used to concentrate heat and transport it from one location to another. In winter, the ground absorbs solar energy and provides a barrier to cold air. In summer, the ground heats up more slowly than the outside air.
As a result, owners of geothermal systems typically enjoy utility bills that are 25-70% lower than with conventional systems. In addition, there are lower maintenance costs.
Additional Advantages of Geothermal Energy
Owners of geothermal systems may also experience the following benefits:
- the National Association of Realtors Appraisal Journal estimates that a home’s value increases by $10-25 for every $1 reduction in the annual utility bill
- a higher year-round comfort level than with conventional systems
- peace of mind of knowing they’re being environmentally responsible
- lower greenhouse gas emissions than a conventional furnace
- elimination of a potential source of poisonous carbon monoxide
- little to no maintenance costs (no costly boiler repairs or cleaning)
