My husband and I are determined to do our part in protecting our environment. We take every opportunity to minimize our carbon footprint. Whenever possible, we either walk or ride our bicycles to our destinations. For longer distances, we take public transportation. We recycle all glass, metal, and plastic, and compost organic waste. The compost works well to fertilize the vegetable garden. My husband designed a system to catch rainwater in order to water the garden. Our home is equipped with solar panels on the roof, which provide sufficient power for all of our appliances. For temperature control, we invested a great deal of money into a geothermal heat pump. Geothermal temperature control is recommended by the Environmental Protection Agency as the most environmentally responsible means of temperature control. For every one unit of energy required to run the system, it generate four units of energy. The geothermal heat pump takes advantage of the relatively stable temperature found underground, drawing from this free energy source to provide both heating and cooling. During the winter months, it draws heat from the ground and transfers it into the home. In the summer, the heat pump simply reverses the operation, extracting warmth from the indoor air and pumping it outside. The heat pump is exceptionally clean, quiet and safe. Because the equipment doesn’t burn fossil fuels to generate heat, there’s no greenhouse gas emissions. There’s no combustion byproducts such as carbon monoxide, formaldehyde or carbon dioxide. While the underground loops system was extremely costly to purchase and implement, we are able to heat and cool our home for approximately a dollar a day.
