ENERGY STAR is the U.S. Environmental Protection Agency's voluntary efficiency label for appliances, heating and cooling equipment, and other products. A product earns the blue ENERGY STAR mark through independent testing showing it meets an efficiency specification stricter than the federal minimum standard for its category. Specifications are revised as technology improves.
Why it matters to you
Refrigerators, dishwashers, and laundry machines run for years, so an ENERGY STAR model that uses less electricity or water for the same work reduces energy use on every cycle of its life. For heating and cooling equipment, the label sits on top of the SEER2, HSPF2, and AFUE ratings rather than replacing them.
Practical guidance
When shopping, look for the ENERGY STAR mark and then compare the yellow EnergyGuide label, which estimates yearly energy use for that specific model. Check the ENERGY STAR product finder to confirm a model is currently certified, since older listings can fall out of date.
ENERGY STAR vs. the EnergyGuide label
| ENERGY STAR | EnergyGuide label | |
|---|---|---|
| Who runs it | U.S. Environmental Protection Agency, with the Department of Energy | Federal Trade Commission |
| Required or voluntary | Voluntary | Required on many major appliances |
| What it tells you | The model meets an efficiency specification above the federal minimum | Estimated yearly energy use and a cost range for that model |
| How to use it | Shortlist efficient models | Compare shortlisted models with each other |
| Look | Blue mark | Yellow label |
What does an ENERGY STAR label actually mean?
It means the model was tested and met the ENERGY STAR efficiency specification for its product category at the time it was certified. The specification is set above the federal minimum, so the model does the same job with less energy than a minimum-standard unit.
What is the difference between ENERGY STAR and the EnergyGuide label?
ENERGY STAR is a pass-or-fail mark: a model either meets the specification or it does not. The yellow EnergyGuide label, required by the Federal Trade Commission on many major appliances, shows estimated yearly energy use and a cost range so you can compare models against each other.
Is ENERGY STAR the same as a SEER2 or AFUE rating?
No. SEER2, HSPF2, and AFUE are efficiency ratings measured for every air conditioner, heat pump, or furnace. ENERGY STAR sets a minimum on those ratings, so a certified unit is one whose rating clears the program threshold for its type.
Does an ENERGY STAR appliance need different repairs?
Not usually. ENERGY STAR models use the same basic parts as other models, such as compressors, pumps, heating elements, and door gaskets. Keeping those parts in good condition, like a tight refrigerator door seal or a clear dryer vent, is what keeps an efficient appliance efficient.
