Is geothermal cooling technology new?
Actually, the basic "modern" technology has been around for more than 50 years and improved upon ever since. To date, over one million installations in the United States alone have allowed a significant amount of homeowners and businesses to enjoy the benefits of geothermal systems. In fact, consumers rank their comfort and satisfaction with geothermal systems higher than any other type of systems.
How much can I really save by installing a geothermal system?
Your exact savings will be determined by many variables such as thermostat settings and
electric rate amongst others. Most homeowners will see a reduction of 30 to 50% in
their cooling costs. In the Cayman Islands, where cooling costs make up 80% this represents
a signficant savings on your electrical bills!
A study by the U.S. Environmental Protection Agency showed that geothermal
systems have the lowest life-cycle costs of all cooling systems currently on the market.
Lower maintenace costs and longer life expectancy of geothermal units should certainly be taken into consideration when determining true savings.
What is the real environmental impact?
According to data supplied by the U.S. Department of Energy (DOE) Office of Geothermal Technologies, nearly 40% of all U.S. emissions of carbon dioxide (CO2) are the result of using energy to heat, cool and provide hot water for buildings. This is about the same amount of CO2 contributed by the transportation sector.
A typical 3-ton residential GeoComfort system produces an average of about one pound less Carbon Dioxide (CO2) per hour of use than a conventional system. To put that in perspective, over an average 20-year lifespan, 100,000 units of nominally sized residential GeoComfort systems will reduce greenhouse gas emissions by almost 1.1 million metric tons of carbon equivalents.
That would be the equivalent of converting about 58,700 cars to zero-emission vehicles, or planting more than 120,000 acres of trees.
