Energy Use of Some Typical Home Appliances

Energy Use of Some Typical Home Appliances Knowing how much electricity each of your appliances uses will also give you a clearer picture of where your energy dollar is going. Powered with this knowledge, you can use energy more efficiently and trim your energy budget.

If you want an estimate of how much electricity your home appliances consume, refer to the Household Appliances list below. If you want a more exact estimate, you can generally find the wattage stamped on the bottom or back of the appliance, or on its "nameplate." The wattage listed is the maximum power drawn by the appliance. Since many appliances have a range of settings (for example, the volume on a radio), the actual amount of power consumed depends on the setting used at any one time.

Use the following formula to estimate the amount of energy a specific appliance consumes:

Wattage x Hours Used Per Day = Daily Kilowatt-hour (kWh) consumption (1 kilowatt (kW) = 1,000 Watts) Multiply this by the number of days you use the appliance during the year for the annual consumption. You can then calculate the annual cost to run an appliance by multiplying the kWh per year by the cost per kWh consumed. Refer to your most recent energy bill for the latest kilowatt-hour rate.
