Cooling and heating account for 47% of energy use in a U.S. household. If you have an air conditioning unit, a simple way to practice energy conservation is to install ceiling fans throughout your home's living spaces to help your air conditioner and furnace work more efficiently. This addition can lower your electricity use and, in turn, could save you money on your utility bills.
Ceiling fans use substantially less energy than your air conditioner, allowing you to increase your thermostat's setting during the warm months by four degrees Fahrenheit without experiencing a reduction in comfort. The U.S. Department of Energy estimates that you can save as much as one percent per degree on your utility bill, which will add up over time.
