Electricity, oil, and gas bills. All homeowners pay for one of more of these utilities, and wish they could pay less. Often times, many of us don’t really know how to control or reduce our utility bills. We resign ourselves to the high bills because we think that’s just the price we have to pay for a comfortable home. We encourage our children to turn off the lights and appliances, but may not recognize the benefits of insulating the attic.
Heating and cooling (“space conditioning”) accounts for 50-70% of the energy used in the average American home. About 20% of that energy goes towards heating water. On the other hand, lighting and other appliances accounts for for only 10-35% of the energy used in most residences. Turning the lights and appliances off makes sense if they’re not needed, but you’ll save even more on your energy costs if the amount of energy needed for heating and cooling is reduced.
Unless your home was constructed with special attention to energy efficiency, adding insulation will probably reduce your utility bills. Much of the existing housing stock in the United States is not insulated to the best level. Older homes are likely to use more energy than the newer homes, leading to extremely high heating and air-conditioning bills. Even if you own a new home, adding insulation may save you enough money in reduced utility bills to pay for itself within a few years, and will continue to save you money for as long as you own the home while increasing the resale value of your house.
