Did you know one of the biggest energy hogs in your home might be lurking in the basement -- and it's something you're not even aware you have? It's called a furnace fan, and it's designed to circulate air through the ductwork system and into individual rooms throughout your house. It's such a big energy hog, it uses about 10 percent of your average household energy every year. If you're looking to make one money-saving change, look into installing an energy-efficient motor, which can cut the usage by as much as 60 percent.
