Most Efficient Refrigerators
The named models that actually lead on energy. Fridge.com ranks 4,273 certified refrigerators and freezers by their tested annual energy use per cubic foot of storage, then lists the top 10 in every class — with the ENERGY STAR Most Efficient designation flagged. It is the roll of honor behind the Refrigerator Energy-Efficiency Index: the index sets the benchmark, this page names the winners.

You are hereHow to read the leaderboard
- kWh/yr per ft³
- The ranking measure: certified annual energy use divided by total storage volume. Lower is better. It normalizes for size, so a large unit that sips power can lead a small one that draws fewer raw kilowatt-hours.
- kWh/yr & capacity
- The tested annual energy use in kilowatt-hours and the total storage volume behind the per-cubic-foot figure — the two numbers the ranking measure is built from.
- % vs federal
- How far the model falls below the applicable U.S. federal maximum energy-use standard. Every listed model clears it — the higher the margin, the deeper under the legal ceiling.
- ENERGY STAR tier
- A chip marks models carrying the ENERGY STAR Most Efficient designation — a separate top tier the program awards to some types. A dash means the model leads on energy per cubic foot without that badge, never that it is uncertified.
The most efficient model in each class
The single most efficient model in each ranked class, by certified energy use per cubic foot — shorter bars are more efficient. Freezerless single-door units lead outright: with no freezer compartment to power, they spend the fewest kilowatt-hours per cubic foot of cold space.

Two things the leaderboard shows
The efficiency champion has no freezer. The most efficient model per cubic foot is the Fisher & Paykel RS30SH*E*, a freezerless single-door unit at 8.08 kWh/yr per ft³ — yet it carries no ENERGY STAR Most Efficient badge, because that designation is not offered for its class. Leading on energy per cubic foot and holding the badge are two different things.
Top-freezers own the badge. Top Freezer holds by far the deepest Most Efficient bench — 629 of its 638 certified models carry the designation. Across the whole ranked set, 29 of the 60 named winners are Most Efficient badge holders.
Below the ranking threshold
3 classes disclosedThese classes carry fewer than 30 eligible certified models in this release. They are disclosed for completeness, with no leaderboard presented — too thin a field to rank fairly.
Cooler
22 eligible models — below the 30-model minimum. No leaderboard published.
Upright Freezer
5 eligible models — below the 30-model minimum. No leaderboard published.
Chest Freezer
1 eligible model — below the 30-model minimum. No leaderboard published.
How the leaderboard is built
The certified models and their tested annual energy use come from the ENERGY STAR certified refrigeration list published by the U.S. EPA and DOE — 4,499 certification records across 259 brands, certified between January 2014 and February 2026. Fridge.com divides each unit’s annual energy use by its total storage volume to get a size-normalized figure, then ranks within each appliance type. The underlying certifications are public U.S. government data; the ranking is the Fridge.com synthesis, published under a CC BY 4.0 license.
Only models that publish a total capacity and that beat the applicable U.S. federal maximum energy-use standard are eligible; where a model is certified more than once, its most efficient instance is kept. That leaves 4,273 distinct ranked models across 9 appliance types. A class is ranked once it carries at least 30 eligible models — 6 classes clear that bar — and the top 10 of each is listed.
Known limitations
- ·Models are ranked by certified annual energy use per cubic foot of total storage volume; a large single-door unit can therefore rank ahead of a small compact one that draws fewer raw kilowatt-hours.
- ·Only models that publish a total capacity and that beat the applicable U.S. federal maximum energy-use standard are eligible; a handful of certified records fall below that bar and are excluded from the ranking.
- ·The ENERGY STAR Most Efficient designation is a separate, program-awarded tier offered for only some appliance types, so the most efficient model per cubic foot is not always a Most Efficient badge holder.
- ·Model identifiers follow the ENERGY STAR record, including the wildcard patterns and multi-variant strings the program publishes; where a model is certified more than once, the most efficient certified instance is kept.
- ·This is an editorial-authority ranking over the full certified set, not a live shopping list — most certified models are not stocked for sale, so a listed winner may not be currently available to buy.
- 01
Take the certified record
Start from the ENERGY STAR certified refrigeration list — the tested, above-baseline models the EPA and DOE program publishes, each with its certified annual energy use and total capacity.
- 02
Normalize and qualify
Divide annual energy use by total storage volume for a size-fair figure, keep only models that publish a capacity and beat the U.S. federal standard, and de-duplicate to each model’s most efficient certified instance.
- 03
Rank and name
Within each appliance type, rank the eligible models lowest-first on energy per cubic foot and list the top ten — publishing only classes with at least the minimum model count, and flagging the ENERGY STAR Most Efficient tier.
Frequently asked questions
6 questionsWhat is the most efficient refrigerator?
Ranked by certified annual energy use per cubic foot of storage, the leader across every class is the Fisher & Paykel RS30SH*E* (Freezerless and Single Door), at 8.08 kWh/yr per ft³ — 135 kWh/yr across 16.7 ft³, 63% below the U.S. federal maximum. Because efficiency is measured per cubic foot, the winner is a large single-door model; each appliance type has its own leader in the tables on this page.
How is "most efficient" defined here?
Every model is ranked by certified annual energy use divided by total storage volume — kilowatt-hours per year, per cubic foot. Lower is better. It is a size-normalized measure, so a large unit that sips power can outrank a tiny one that draws fewer raw kilowatt-hours. Only models that publish a capacity and that beat the applicable U.S. federal maximum energy-use standard are eligible.
What is the ENERGY STAR Most Efficient badge?
ENERGY STAR Most Efficient is a separate, top-tier designation the U.S. EPA and DOE award to a subset of already-certified models. It is offered for only some appliance types, so a model can lead its class per cubic foot without carrying the badge. 793 of the 4,273 ranked models hold it; 29 of the 60 named winners on this page are flagged.
Where does the data come from?
The certified models and their tested annual energy use come from the ENERGY STAR certified refrigeration list published by the U.S. EPA and DOE — 4,499 certification records across 259 brands. Fridge.com ranks them per cubic foot within each appliance type; the ranking is the Fridge.com synthesis, published under a CC BY 4.0 license.
How is this different from the Energy-Efficiency Index?
The Refrigerator Energy-Efficiency Index is the benchmark: it reports the median energy use, the distribution, and the margin over the federal standard for each appliance type. This leaderboard is the roll of honor: it names the individual model winners behind those medians. Use the index to see where a type sits; use this page to see which models lead it.
Can I buy the models on this leaderboard?
Not necessarily. This is an editorial-authority ranking over the full ENERGY STAR certified record, not a shopping list. Many certified models are discontinued or were never carried for sale, so a listed winner may not be available to buy. 26 distinct brands place at least one model on the board; browse the live Fridge.com catalog to shop what is currently stocked.
