Appliance Energy Use
Running the appliances needed for the comforts and conveniences of everyday life comes with not just one cost, but two: the cost of purchase and the cost to operate. When you replace older appliances with newer, more efficient models you not only save money but energy. To help determine appliance efficiencies, most appliances display a bright yellow and black “Energy Guide” label.
Knowing how much energy your appliances consume can help you make smart energy choices. There are online appliance energy calculators that can be used to get an estimate of usage. For a better idea of your appliance use and operating costs, you can use the formula below. But remember that factors such as family size, lifestyle, amount of usage and wattage ratings affect consumption.
- Determine the number of hours per day an appliance runs
- Check the wattage of the appliance (usually stamped on the bottom, back or nameplate)
- Find the daily kWh consumption: (wattage x hours used/day) divided by 1,000
- Estimate monthly usage: (daily kWh consumption x hours used/month x kWh rate*)
