The amount of watts of electricity that a refrigerator uses varies depending on size, age and whether or not the refrigerator is a standard or Energy Star model.

Larger refrigerators use more electricity than smaller refrigerators, because there is more area to cool. Age is also a significant factor when comparing electricity usage of refrigerators. Refrigerator models manufactured during the years 1993 to 2000 may use twice the electricity of newer models. Lastly, Energy Star models are at least 20 percent more efficient than standard models.

The refrigerator is the second-largest user of electricity in most homes. Air conditioners typically use the most electricity in a home.
