A:Answer I don't think it uses much energy at all. The yellow "Energy Guide" tag that comes with it says "Estimated Yearly Cost = $33" in the "Models with similar features" category, which ranges from $18/year to $39/year. So it's towards the top of that range but not that much. The tag ALSO says "All Models" (whatever that means) range from $18/year to $70/year. Finally, the tag says "Estimated Yearly Electricity Use = 272kWh." I also took a picture of the Specs on the back of the unit, which I will post here. That's all I can tell you about "energy usage" for this 48-can beverage refrigerator-cooler.
