Benefits and Savings
Financial:
Geothermal heat pump systems
can reduce a home's annual energy costs by up to 50%.
The pie charts below show the breakdown of a home's
energy consumption prior to making the switch to geothermal
and after making the switch to geothermal.
A home still needs the same quantity of heat to maintain thermal comfort, but with a geothermal system, most of this heat comes from a free source - the ground. Overall energy consumption of the home remains the same, but as seen below a significant portion (here it is 59%) of the energy consumed is free!

The drawback of a geothermal system is its initial investment. These systems cost more than conventional oil or gas furnaces and central air conditioners.
With the savings in energy bills, however, these systems pay for themselves easily and typically have a return on investment of 200% over their lifetime of 25 years. This return on investment is a conservative estimate and not accounting for any increases in oil prices in the next 25 years. Should the cost of oil rise, the payback period will decrease and the return on investment will increase.
Several financial incentives exist for geothermal heat
pump systems. These include incentives
from the CT Clean Energy Fund, a 30%
federal tax credit, a $500/ton rebate from CL&P
or The
United Illuminating Company, and a variety of low
interest loans. Furthermore, these systems are exempt
from both sales and property tax.
Environmental:
Over the past several decades, carbon dioxide (CO2) emissions have significantly increased, as shown in the graph below. While the specific impacts of this increase are constantly debated, its environmental ramifications are most certainly detrimental. A great benefit of a geothermal heat pump system is that it completely replaces traditional fossil-fueled systems, thus reducing a home's carbon footprint. While it is typically assumed that the transportation sector is the major CO2 emitter, buildings are responsible for 40% of all CO2 emissions in the United States. Reducing the energy consumption of homes is a critical component of the nation's CO2 emission reduction goals.

The only energy input requirement of a geothermal heat pump system is electricity. Therefore, with the addition of solar panels to a home, or a green-power purchase agreement with a utility company, a geothermal system easily becomes 100% green.
