With the average U.S. household spending around $2,000 annually on energy costs, there are lots of things you can do to cut waste and save money. While going around the house and unplugging everything is effective, it's not the most practical solution. The Department of Energy has come up with a list of 12 energy guzzlers that draw power when plugged into a socket, even if they're turned off. While things like telephones and modems may be tricky to turn off, items like computers, televisions, DVD players, toaster ovens, coffee makers, stereos, phone chargers and even lamps in rarely used rooms can help make a difference. Unplugging these items can reduce your bill by as much as 10 percent -- or $200.
