Top 21 Energy Efficient Full Sized Refrigerators

When you’re talking about the most efficient refrigerators, it can be difficult to determine which are best due to the inefficiency of the standard metrics used to depict efficiency.

First there is the Energy Star compliancy, which means almost nothing now for comparison purposes given that almost all new refrigerators will be Energy Star compliant. Then you have the posted killowatt hours (kWh) and operating costs that are shown on the black and yellow labels. The problem with this is it doesn’t account for the size of the fridge. Using 400 kWh per year to cool a 20 cubic foot fridge without a freezer isn’t as efficient as using the same 400 kWh per year to cool a 32 cubic foot fridge with a freezer.

So for this comparison we are using a different metric derived from the capacity of the refrigerators and the yearly operating costs. This Yearly Operating Cost / Cubic Foot ratio (YOP/CuF) gives an idea of how much it will cost to cool one cubic foot for a year. This helps to make it more clear which refrigerators are using the most efficient designs. YOP/CuF isn’t perfect of course, as it doesn’t account for how much of that space is freezer (more energy intensive) and how much is fridge. It also doesn’t account for ice makers and water dipensers, or other accessories that might impact the overall electric usage. But it’s still far more relevent than just looking at Yearly Operating Cost.

21. Samsung RFG297AABP/XAA, RFG297AAPN/XAA, and RFG297AARS/XAA

Capacity: 29.0 cubic feet (Freezer: 9.0 cubic feet, Refrigerator: 19.5 cubic feet)
Energy Use: 445 kWh
Yearly Operating Cost: $47
YOP/CuF: 1.62
Configuration: Side-by-Side
Ice Maker: Door
Water Dispenser: Door

The most expensive refrigerators to run on this list are the Samsung RFG297AABP/XAA, RFG297AAPN/XAA, and RFG297AARS/XAA. These refrigerators come in at $47 Yearly Operating Cost, but are still relatively efficient to most fridges out there due to their 1.62 YOP/CuF rating. To put that in perspective, the average full sized refrigerator comes in with a YOP/CuF ratio of 2.41 and the least efficient modern refrigerators sport a hefty 4.90 YOP/CuF! So even these refrigerators at #21 should be considered efficient ones in comparison.

Energy Use: 383 kWh
Yearly Operating Cost: $41
YOP/CuF: 1.61
Configuration: French Door
Ice Maker: Door
Water Dispenser: Door

Maytag’s sole entry on this list is the french door MFI2670XEB fridge model which comes in at just #19. This isn’t a very good showing, but still puts it ahead of several other well known fridge manufacturers who didn’t make the list at all. The MFI2670XEB does include an ice maker and water dispenser in the door, but the freezer isn’t very large at all. While Maytag has hung it’s hat (and reputation) on reliability, perhaps the Maytag repair man should be spending his spare time designing more efficient refrigerators instead of napping.

Yearly Operating Cost: $30
YOP/CuF: 1.46
Configuration: Top Freezer (Right Hinge)
Ice Maker: Optional
Water Dispenser: No

The first of 2 traditional looking top freezer (right hinge) refrigerators on this list, the Frigidaire FGHT2146KF is one of the few choices you have if you are looking for an energy efficient fridge in that configuration. It has an optional ice maker (no door access) but no water dispenser. Door access for ice makers and water dispensers are of course much more common on french door and side-by-side models.

The YOP/CuF of 1.46 makes this a respectably energy efficient fridge regardless of door configuration.

Yearly Operating Cost: $43
YOP/CuF: 1.41
Configuration: French Door
Ice Maker: Door
Water Dispenser: Door

These french door bottom freezer models from Kenmore are somewhat expensive to run at $43 Yearly Operating Cost, but given their rather large 30.5 cubic feet capacity (10.0 cubic feet of which is freezer space) along with the standard water dispenser and ice maker in the door mean these fridges have a respectible 1.41 YOP/CuF without having to skimp on features.

Kenmore’s 5th (but certainly not last … ) entry on this list already, the 51374 is a side-by-side fridge with a decent sized freezer compartment at 10.2 cubic feet. Matched with an ice maker and water dispenser in the door, Kenmore has a feature rich, efficient refrigerator here.

YOP/CuF: 1.36
Configuration: Top Freezer (Left Hinge)
Ice Maker: Optional
Water Dispenser: No

The most efficient top freezer fridge on this list, the Frigidaire FFHT2126LS is also the fridge with the lowest overall Energy Use and Yearly Operating Cost. It’s lower capacity means with a YOP/CuF rating of 1.36 it doesn’t quite compete with the most efficient refrigerators though. It also has a relatively small freezer as well as no standard ice maker or water dispenser. Still, if you are looking for a top freezer configuration, or aren’t so worried about space as you are operating costs, the FFHT2126LS deserves a close look.

Frigidaire’s final entry on this list reaches the #5 spot on the back of a 1.33 YOP/CuF rating. The second best side-by-side configuration and including a water dispenser and ice maker in the door makes this a well-rounded fridge that proves Frigidaire designs can compete with the most efficient refrigerators out there.

It’s worth noting that the 72062 comes with the largest freezer capacity of any of the french door refrigerators on this list (tied with the Samsung RSG309AARS overall at 11.5 cubic feet). This makes it’s ranking at #3 even more impressive. The 72062 comes with an ice maker and water dispenser to boot.

Perhaps the most impressive refrigerator on this list is the Kenmore 51373. This side by side fridge comes with a water dispenser and ice maker in the door. That means it’s 1.25 YOP/CuF rating the best for refrigerators with those features. It’s 10.2 cubic feet of freezer space is also the 3rd largest on the list. All-in-all, the Kenmore 51373 is a fridge to be reckoned with.

Kenmore closes out it’s domination of the top 3 of this list with 4 very similar models of french door refrigerators. These sport a relatively small bottom freezer of 7.2 cubic feet, which keeps them from setting themselves truly apart from the #2, #3, and #4 entries on this list. Still, with a YOP/CuF of 1.22, while still including an ice maker and water dispenser in the door, and having the largest capacities of any of the fridges on this list, the Kenmore 71032, 71033, 71039, and 71054 deserve to be recognized as the most efficient refrigerators on the market today!
