Unplug it!

One simple thing that everyone can do, at absolutley no cost is to unplug certain things when they are not in use. I'm not saying unplug your alarm clock or coffeemaker with a clock (it would save a small amount of energy, but not practical to reset your clock all the time) but if you unplug simple items like cellphone chargers or other battery chargers, printers and anything else with a transformer. Eliminating this "leaking" electricity can save you anywhere from 6 to 26 percent of your household electricity use.
