If you're looking to shave money off your electric bill, the first thing you should do is sit down with an online electric bill calculator. Your local power company may have a bill calculator or estimator available on their Web site, or you can go with a generic electric bill calculator. Using one of these calculators to break down your electric bill can make you aware of which devices in your home are eating the most power, and what alternatives can save you money. For example, if your power company offers reduced rates for off-peak usage, you can arrange to use heavy electricity consuming devices, such as clothes dryers, in those off-peak hours.
by pressing the on/off button
press the reset button on the back of the calculator that worked for me
