Geothermal Heating and Cooling Versus Conventional Heating and Cooling

In the 21st century, alternative energy is a big topic. Some forms include solar energy, wind turbines and nuclear power. A different form of alternative energy is geothermal energy. According to Green Building Advisor, geothermal energy is "hot water or steam extracted from reservoirs beneath the Earth's surface" (green). This paper will benefit the Pennsylvania Builders Association (PBA) and educate the organization on the advantages of geothermal energy. The PBA is associated with the National Association of Home Builders and it is a non-profit statewide trade organization that was chartered in 1952. The Pennsylvania Builders Association should encourage the use of geothermal energy sources throughout the state and local levels because this source of energy will prove to be more economically and environmentally friendly.

According to Green Comfort, "The Ground Source Heat Pump (GSHP) is one of the most efficient residential heating and cooling systems available today, with heating efficiencies 50 to 70% higher than other heating systems and cooling efficiencies 20 to 40% higher than available air conditioners.

That directly translates into savings for you on your utility bills. " (Frequently)

This paper will compare both geothermal and conventional heating and cooling systems and determine which is better. A brief history of both systems will be discussed along with a conversation about how they work. The advantages and disadvantages of both systems will also be stated. Specifically the costs involved and the sources of power will be discussed. The conclusion will end finding that geothermal power proves to prevail.

History: Geothermal Energy

Up until the 1800s, hot springs were the primary source of hot water for bathing and cooking. Some hot springs also heated buildings, but this use was limited.
