Home Energy Management ......
What you pay to operate an electric appliance depends on its wattage, the number of hours you use it and the cost of the electricity. This chart below, based on information from the Electric Energy Association, gives a rough estimate of the annual usage in kwh for most common appliances. (Time used for thermostatically controlled products that cycle on and off, such as irons and ovens is the actual "on" time.) To estimate the annual cost for any appliance you own, find out what your local kwh rate is and multiply it by the kwh used per year shown here for that appliance. For more accurate figures, multiply the wattage rating listed on the appliance by the estimated number of hours used per year, multiply the result by your kwh rate, then divide by 1,000. You have some idea now where your highest costs are and, as electric rates climb, where to try to cut down.
