Do a nightly energy sweep
We all have left fans, lights or appliances on at night while we sleep, but doing so wastes increasingly expensive energy.
To save money, do a nightly sweep through the house to make sure all your electric devices are turned off before you go to bed. It may be a pain, but the savings from simply turning everything off can add up quickly. For example, just leaving your cable box plugged in and not on for a year would cost you $17.83, according to the Department of Energy. Try turning off your cable box (and other devices) between uses and watch the savings climb.
