ENERGY STAR and EnergyGuide labels can both help you compare refrigerators, but they do not mean the same thing.
The blue ENERGY STAR mark identifies refrigerators that meet the program’s efficiency requirements. The yellow EnergyGuide label shows how much electricity a particular model is expected to use and how its energy consumption compares with similar appliances.
Quick answer: Use ENERGY STAR to identify efficient models, then use the EnergyGuide label to compare annual kilowatt-hour consumption among refrigerators of a similar size and configuration. The model with the ENERGY STAR logo is not automatically the cheapest one to operate if it is larger or has more energy-consuming features.
What Does ENERGY STAR Mean on a Refrigerator?
ENERGY STAR is a voluntary energy-efficiency program administered by the U.S. Environmental Protection Agency. A refrigerator must meet the program’s current technical requirements before it can carry the ENERGY STAR label.
According to ENERGY STAR, certified residential refrigerators are currently about 9% more energy-efficient than models that meet the federal minimum energy-efficiency standard.
That percentage compares a certified refrigerator with the applicable minimum standard. It does not mean every ENERGY STAR refrigerator uses 9% less electricity than every non-certified refrigerator on the market.
Size, freezer position, number of doors, ice-making features, installation type, and other design differences can substantially affect annual energy consumption.
ENERGY STAR and EnergyGuide Are Different
Appliance listings sometimes display the blue ENERGY STAR mark beside a yellow EnergyGuide label. Each gives you different information.
| Label | What It Tells You | How to Use It |
|---|---|---|
| ENERGY STAR | The model meets the program’s energy-efficiency requirements | Use it to identify certified efficient models |
| EnergyGuide | Estimated annual electricity use, operating cost, and comparison range | Use it to compare similar refrigerators using actual kWh figures |
The ENERGY STAR label is a qualification mark. The EnergyGuide label gives you model-specific numbers.
For most buying decisions, the best approach is to use both rather than relying on either label alone.
How to Read a Refrigerator EnergyGuide Label
The yellow EnergyGuide label is designed to help shoppers compare the energy use of similar appliances. Refrigerator labels generally include several important pieces of information.
Estimated Yearly Electricity Use
This figure is shown in kilowatt-hours per year, usually written as kWh/year. It is the most useful number on the label because you can multiply it by your own electricity rate.
For example, a refrigerator rated at 400 kWh per year would have the following estimated annual cost at an electricity rate of $0.15 per kWh:
400 kWh × $0.15 = $60 per yearYou can find more examples in our guide explaining how much a refrigerator costs to run.
Estimated Yearly Operating Cost
The label also provides an estimated annual operating cost. This figure is calculated using standardized assumptions and a national average electricity price.
Your actual cost may be different. Electricity prices vary by location, and refrigerator use changes with room temperature, door openings, temperature settings, maintenance, and household habits.
Use the annual kWh figure with the rate from your electricity bill when you want a more relevant estimate.
Comparison Range
The EnergyGuide label places the model within a range of estimated energy costs or energy use for similar appliances.
Pay attention to the word similar. A compact top-freezer refrigerator should not be compared directly with a large French-door model simply because both store refrigerated food.
The comparison range is useful only when the appliances have reasonably similar capacities and configurations.
Model and Capacity Information
Check the model number and product category shown on the label. Confirm that it matches the exact refrigerator you are considering, especially when a retailer offers several capacities, finishes, or closely related model variations.
Does ENERGY STAR Mean the Refrigerator Uses the Least Electricity?
Not necessarily.
A large ENERGY STAR-certified French-door refrigerator may use more electricity each year than a smaller non-certified top-freezer model. The certified appliance may be efficient for its size and product class while still consuming more total energy.
This is why annual kWh matters. Compare refrigerators that meet the same practical requirements rather than selecting the largest certified model within your budget.
Start by deciding how much capacity you need, which configuration fits your kitchen, and which features are genuinely useful. Our guide to refrigerator types explains the practical differences among top-freezer, bottom-freezer, side-by-side, and French-door designs.
What Affects Refrigerator Energy Consumption?
Certification is only one part of refrigerator efficiency. The appliance’s physical design and features also affect its annual energy use.
Overall Size
Larger refrigerators generally consume more electricity because they have more interior space to cool.
A household that needs 18 cubic feet of storage is unlikely to save money by buying a 28-cubic-foot refrigerator merely because the larger model has an ENERGY STAR logo.
Choose enough capacity for normal food storage without paying to cool large areas that remain unused.
Freezer Position
ENERGY STAR advises that refrigerators with top freezers tend to use less energy than comparable bottom-freezer and side-by-side models.
That does not make a top-freezer model the best choice for every household. Accessibility, organization, kitchen layout, and storage habits still matter.
Number of Doors
More doors can mean more seams where cold air may escape. Multi-door designs can also include separate compartments and controls that add complexity.
Compare the EnergyGuide figures instead of assuming that one door configuration is always more efficient.
Ice Makers and Water Dispensers
Automatic ice makers, through-the-door dispensers, heaters that prevent condensation, pumps, and water-filtration systems can increase electricity use or ongoing ownership costs.
These features may still be worthwhile if your household uses them regularly. The important question is whether their convenience justifies the higher purchase price, reduced interior space, and possible increase in energy consumption.
Built-In and Counter-Depth Designs
Built-in and counter-depth refrigerators are often purchased for appearance and kitchen integration rather than the lowest possible operating cost.
Pay close attention to installation clearance and ventilation requirements. Poor ventilation can make even an efficient refrigerator work harder than intended.
Ambient Room Temperature
A refrigerator installed beside an oven, in direct sunlight, or in a hot garage may consume more electricity than its standardized label estimate suggests.
Before installing a refrigerator in a garage, outdoor kitchen, or unconditioned space, confirm that the model is approved for the expected ambient-temperature range.
How to Compare Two Refrigerators Properly
Follow this process when comparing refrigerator efficiency.
- Measure your available space. Include door clearance, ventilation space, cabinet depth, and the path needed to deliver the appliance.
- Choose a suitable capacity range. Avoid comparing a compact model with a much larger family refrigerator.
- Compare similar configurations. Place top-freezer models against other top-freezer models and French-door models against comparable French-door models.
- Record annual kWh. Use the EnergyGuide label for each exact model.
- Calculate local operating cost. Multiply annual kWh by your electricity rate in dollars per kWh.
- Compare purchase price and annual savings. A more efficient refrigerator may not recover a large price premium quickly.
- Review reliability and warranty coverage. A small energy saving may not offset repeated repair costs.
- Check for rebates. ENERGY STAR and local utilities may list regional incentives, but availability changes by location and date.
Example Refrigerator Comparison
Suppose two similarly sized refrigerators meet your storage and installation requirements.
| Feature | Model A | Model B |
|---|---|---|
| ENERGY STAR certified | Yes | No |
| Annual energy use | 380 kWh | 450 kWh |
| Purchase price | $1,150 | $1,000 |
| Annual cost at $0.15/kWh | $57.00 | $67.50 |
Model A saves 70 kWh per year:
450 kWh − 380 kWh = 70 kWh saved per yearAt $0.15 per kWh, the estimated annual dollar saving is:
70 × $0.15 = $10.50 per yearThe efficient model costs $150 more upfront. Based only on electricity savings, the simple payback would be:
$150 ÷ $10.50 = approximately 14.3 yearsThis does not automatically make Model A a poor choice. It may have better construction, quieter operation, a longer warranty, improved storage, or a rebate. It does show why you should calculate the difference rather than assuming that an efficiency label guarantees immediate financial savings.
How Much Can an ENERGY STAR Refrigerator Save?
ENERGY STAR currently estimates that properly recycling an old refrigerator and replacing it with a new certified model can save about $150 over a 12-year product lifetime.
Treat that figure as a broad program estimate rather than a promise for every household. Your savings depend on:
- The energy use of the refrigerator being replaced
- The annual kWh rating of the new model
- Your local electricity rate
- Whether the old refrigerator is removed or kept as a second appliance
- How the new refrigerator is installed and used
An older second refrigerator operating in a hot garage may offer a larger savings opportunity than replacing a reasonably efficient primary refrigerator.
The ENERGY STAR Flip Your Fridge calculator can provide an estimate based on the age and type of the existing appliance.
What the Labels Do Not Tell You
Energy labels are useful, but they do not provide a complete refrigerator review.
They do not tell you:
- How noisy the refrigerator sounds in a quiet kitchen
- How conveniently the shelves and drawers are arranged
- Whether the doors fit your kitchen layout
- How well the model maintains temperature in real household conditions
- How reliable its ice maker, compressor, electronics, or door seals may be
- How much replacement filters and repairs could cost
- Whether the manufacturer provides strong service support in your area
Use efficiency information alongside dimensions, capacity, ownership costs, warranty terms, and recurring customer complaint patterns.
How to Keep an Efficient Refrigerator Running Efficiently
The EnergyGuide estimate is based on standardized testing. Installation and maintenance can affect what happens in your home.
- Set the refrigerator to a safe temperature without making it unnecessarily cold.
- Keep the freezer at 0°F.
- Maintain the installation clearances listed in the manual.
- Keep exterior ventilation openings clear.
- Inspect and clean door seals.
- Clean accessible condenser coils only when the manufacturer recommends it.
- Avoid placing the appliance beside strong heat sources.
- Do not block the refrigerator’s internal air vents.

Frequently Asked Questions
Are all new refrigerators ENERGY STAR certified?
No. New refrigerators must comply with applicable federal efficiency standards, but only models that satisfy the ENERGY STAR program’s additional requirements can carry its certification mark.
Is ENERGY STAR the same as the yellow EnergyGuide label?
No. ENERGY STAR identifies certified efficient products. EnergyGuide provides estimated energy-use and operating-cost information for the individual appliance and compares it with similar models.
Should I choose the refrigerator with the lowest annual kWh?
Choose the lowest practical energy use among refrigerators that meet your capacity, installation, configuration, and feature requirements. A very small refrigerator may use less energy but still be unsuitable for your household.
Is the operating cost on the EnergyGuide label exact?
No. It is an estimate based on standardized use and an assumed energy price. Multiply the annual kWh by your own electricity rate for a more relevant calculation.
Do ENERGY STAR refrigerators qualify for rebates?
Some certified refrigerators may qualify for utility, retailer, local, or manufacturer incentives. Programs vary by location and can change, so verify current eligibility before making a purchase.
Should I replace a working refrigerator solely for energy savings?
Calculate the likely savings first. Consider the old refrigerator’s annual energy use, repair history, temperature stability, replacement price, and expected service life. A small difference in annual electricity cost may not justify immediate replacement.
Final Takeaway
ENERGY STAR certification is a useful starting point, but it should not be the only factor in your refrigerator decision.
First identify the size, configuration, and features your household needs. Then compare the annual kWh figures on the EnergyGuide labels of similar models. Calculate operating costs using your local electricity rate and weigh the savings against purchase price, reliability, warranty coverage, and practical usability.
This method provides a clearer buying decision than relying on a certification logo or a broad lifetime-savings estimate alone.
