Frequently asked questions
How many models does this cover?
9421 ENERGY STAR certified models across 9 appliance categories, of which 8602 carry a computed operating-cost estimate.
Are the operating costs real prices?
No — every operating cost is computed from a model's measured energy use at the EIA U.S. national-average residential electricity rate. It's a comparison estimate, not a quote; your real cost depends on your local rate and usage.
