Appliance Energy Consumption Chart

Use the chart below to estimate the Average Daily Watts consumed by each appliance/device.

To calculate the Average Daily Watts for a given appliance/device:

  1. Lookup the Estimated Energy Usage per Hour
  2. Multiply Estimated Energy Usage per Hour times the estimated hours of operation per day, for the device.
