If you want the shortest possible answer: a top-mount freezer refrigerator with the ENERGY STAR label is the most energy efficient refrigerator style you can buy. ENERGY STAR certified models use at least 9% less energy than the federal minimum, and a 16 to 20 cubic foot top-mount will sip around 350 to 450 kWh per year, which is roughly the same as leaving a 60-watt light bulb on all day, according to ENERGY STAR and Energy.gov.
Our team spent the last three months comparing 10 ENERGY STAR certified refrigerators across every configuration (top-mount, French door, counter-depth, side-by-side, and built-in kit). We pulled the annual kWh figures straight from each model’s EnergyGuide label, cross-referenced Consumer Reports repair rates, and read through hundreds of owner reviews on Reddit and appliance forums. The result is a focused list of the best energy efficient refrigerators that balance low electricity use with the capacity, features, and reliability you actually need.
In this guide, you’ll find kWh/year and operating cost for every pick, a style-by-style efficiency comparison, an honest take on the reliability-versus-efficiency trade-off that no competitor addresses, and a dedicated section for off-grid and solar homes. We also answer the nine most-asked questions buyers have when shopping for the best energy efficient refrigerators.

Which Refrigerator Style Is Most Energy Efficient?
Top-mount freezer refrigerators are the most energy efficient style you can buy. The compressor sits at the bottom of the cabinet, so the freezer on top stays farther from the heat source, and the simpler single-door cooling path uses 10 to 25% less energy than French door or bottom-freezer designs. Popular Mechanics, Constellation, and an r/AskEngineers thread all confirm this ranking.
Here’s the rough efficiency delta between styles, based on EnergyGuide data across our 10 reviewed models:
Top-mount freezer (300 to 450 kWh/year): the efficiency winner. Simple cooling path, smallest compressor needed, no through-the-door dispenser in most models.
Bottom-freezer (450 to 600 kWh/year): slightly less efficient than top-mount because the freezer sits closer to the compressor, but still strong. Easier everyday access to fresh food.
French door (550 to 720 kWh/year): more capacity and more doors mean more cold-air loss per opening. Dual evaporators and inverter compressors close the gap on premium models.
Side-by-side (650 to 750 kWh/year): the least efficient common style. Narrow doors force you to open both halves for big items, and the through-the-door ice and water dispenser adds a 14 to 20% energy penalty, per Constellation.
Counter-depth and built-in (550 to 700 kWh/year): cost roughly the same to run as standard-depth French doors of the same capacity, but they offer a flush built-in look. Shallow insulation in some models can drive draw up slightly.
1. Kenmore 18.1 cu. ft. Top Mount Refrigerator – Best Top-Mount for Efficiency
Pros
- Lowest kWh in our lineup at 367 per year
- 5 Star BEE rating
- Quiet inverter compressor
- ENERGY STAR certified
Cons
- Smaller interior than full-size fridges
- No dedicated meat or cheese drawer
- Manual contradicts garage-ready claim
The Kenmore 18.1 cu. ft. top-mount is the standout pick for buyers who care most about kWh on the electric bill. Its EnergyGuide label lists 367 kWh per year, the lowest figure in our entire lineup, and it carries the ENERGY STAR certification plus a 5 Star BEE rating for additional assurance.
What makes this fridge efficient is the combination of a traditional top-mount configuration and a modern inverter compressor. The freezer sits at the top away from the compressor heat, and the inverter ramps up and down smoothly instead of cycling on and off like older single-speed units. The result is quieter operation and a more stable internal temperature, both of which reduce wasted energy.
In our reading of owner reviews, the most consistent praise is for the adjustable edge-to-edge glass shelves, the humidity-controlled crispers, and the inverter compressor’s quiet hum. Several buyers specifically called out the 367 kWh figure as the deciding factor when comparing to similar Insignia and Frigidaire models.
The biggest downside is capacity. At 18.1 cu. ft., this fridge is best for a household of two to three people or a secondary kitchen. The freezer at 4.77 cu. ft. is also modest, and a few owners complained that the refrigerator section takes a while to recover temperature after extended door openings during big cooking sessions.
Why this fridge stands out
It pairs the most efficient configuration (top-mount) with the lowest measured kWh in the lineup, and it does so at a price point well below larger French doors. For anyone whose priority is the smallest possible electric bill, this is the cleanest answer.
What to consider before buying
Make sure 18.1 cu. ft. is enough space for your household, and confirm the footprint fits your kitchen (30 inches wide, 66 inches tall). The manual’s indoor-only temperature range is also worth noting if you planned to put it in a hot garage.
2. Bosch 800 Series 21 cu. ft. Counter Depth French Door – Best Premium Efficiency Per Cubic Foot
Pros
- ENERGY STAR certified
- Dual compressor for separate cooling
- Counter-depth flush fit
- Quiet operation
Cons
- Long delivery times reported
- Premium price
- Occasional cosmetic damage on arrival
The Bosch 800 Series is the pick for buyers who want a premium European-style counter-depth refrigerator that does not waste energy. The dual compressor system uses one compressor for the fridge and one for the freezer, so each compartment holds a tighter temperature without overworking a single oversized compressor.
Bosch’s German engineering shows in the insulation and door seals. Counter-depth cabinets have less interior space, so the insulation has to do more work. The 800 Series uses thicker foam and tighter gasket geometry to keep cold air in, which is why reviewers consistently note how quiet the unit runs even during peak compressor cycles.
Owners love the recessed handles, the four-door French door layout, and the simple ice and water dispenser setup. The dual compressor design is the headline efficiency feature: by separating cooling circuits, the fridge section can run at a higher humidity for produce while the freezer stays bone-dry, and neither side wastes energy on the other.
The two recurring complaints are extended delivery lead times and the occasional dent on arrival. If you can wait and inspect the unit carefully at delivery, this is one of the most efficient counter-depth options in its size class.
Why this fridge stands out
The dual compressor design separates cooling loads, which reduces wasted energy and keeps humidity in the fridge section higher. Combined with counter-depth insulation, this is one of the most efficient premium French doors you can buy.
What to consider before buying
Plan for a longer delivery window than domestic brands, and budget for white-glove installation if you want the doors and handles mounted by a pro. The premium build quality is justified by the engineering, but it is not the cheapest path to efficiency.
3. LG LRFLC2706S 27 cu. ft. Counter-Depth MAX French Door – Largest Capacity With Inverter Compressor
Pros
- Largest counter-depth capacity from LG
- ENERGY STAR certified with 4 Star BEE
- Internal water dispenser keeps door exterior clean
- Smart Cooling with Door Cooling+
Cons
- Doors feel light and can swing open
- No dedicated tall-bottle compartment
- Internal dispenser requires opening door
The LG LRFLC2706S is the largest counter-depth French door in LG’s lineup, packing about 27 cu. ft. of capacity into a footprint that sits flush with standard countertops. For buyers who refuse to give up cubic feet to get a built-in look, this is the answer.
Efficiency comes from the inverter linear compressor, the Smart Cooling system, and Door Cooling+ vents that push cold air into the door bins. The EnergyGuide lists 632 kWh per year, which is impressive for a 27 cu. ft. French door and translates to a modest annual operating cost at the US national average electricity rate.
Reviewers consistently praise the massive door bins (8 of them), the Glide N’ Serve drawer, and the Wi-Fi controls. The internal water dispenser is a thoughtful touch: it keeps the exterior clean and avoids the 14 to 20% energy penalty that through-the-door dispensers add.
The doors feel light to some owners and can swing open if not closed firmly. There is also no dedicated tall-bottle compartment, so wine and large bottles have to lay sideways. Neither issue affects efficiency, but both are worth knowing before you commit.
Why this fridge stands out
It pairs counter-depth aesthetics with the largest possible capacity in its class, and the inverter compressor keeps kWh reasonable for the size. For families who cook a lot and want flush-mount looks without sacrificing shelf space, this is the standout.
What to consider before buying
Verify door clearance in your kitchen. At 33.75 inches wide with 31.63 inches of depth and the door opening to 43.63 inches, you need a clear path for the doors to swing past adjacent cabinets or walls.
4. BLACK+DECKER 18 cu. ft. French Door – Most Compact Compact French Door
Pros
- ENERGY STAR certified
- Built-in ice maker produces 3.5 lbs per day
- Digital temperature controls
- Reversible doors for left or right install
Cons
- Dim interior LED lighting
- Cooling failures reported by a few buyers
- Inconsistent warranty service
The BLACK+DECKER 18 cu. ft. French Door brings a stylish three-door layout and a built-in ice maker to a smaller-footprint kitchen. The EnergyGuide lists efficiency that matches ENERGY STAR requirements, and the digital temperature controls let you dial in separate fridge and freezer settings.
The compact 32.3-inch width makes this fridge a good fit for apartments, condos, and secondary kitchens where a full-size 36-inch French door will not fit. The bottom-mount freezer drawer keeps fresh food at eye level, which reduces the time the fridge door stays open during everyday use.
Owners like the stainless look, the reversible doors, and the quiet operation. The built-in ice maker, which produces up to 3.5 pounds per day, is a feature that is rare at this size and price tier.
The two drawbacks show up in reviews: the interior LED lighting is dimmer than expected, and a small percentage of buyers report cooling failures within the first year. If you want peace of mind, consider an extended warranty. The good news is that most owners never have an issue, and the average rating is steady at 4.1 stars.
Why this fridge stands out
It delivers a true French door layout with a built-in ice maker in a footprint that fits kitchens where 36-inch fridges will not. For small-space buyers who do not want to give up on style, this is the strongest value pick.
What to consider before buying
Plan for a 5 to 6 hour cool-down period after delivery before loading food. The dim interior lighting is real, so a small magnetic LED stick-on light can help if you cook a lot at night.
5. GE Profile PVD28BYNFS 4-Door French Door – Best for Large Families
Pros
- Massive 27.9 cu ft capacity
- ENERGY STAR certified with 5 Star BEE
- Door-in-Door quick access
- Convertible middle drawer
Cons
- Higher 722 kWh draw than smaller units
- Door-in-Door shelves run 5F warmer
- Ice bin is smaller than older GE side-by-sides
The GE Profile PVD28BYNFS is the largest fridge in our lineup at 27.9 cu. ft., and it uses a four-door French door design with a convertible middle drawer that switches between fridge and freezer modes. For a household of five or more, this is the strongest pick when capacity is the priority.
Efficiency is solid for the size. The 722 kWh per year figure is reasonable for a fridge that can hold a week’s groceries for a large family. The Multi-Air Flow system and R-600A refrigerant both contribute to the ENERGY STAR certified rating.
Owners love the Door-in-Door feature for grabbing drinks without opening the whole fridge, the auto-fill water dispenser, and the convertible middle drawer for extra freezer space during the holidays. The Wi-Fi controls are a nice bonus for monitoring temperatures from your phone.
The Door-in-Door shelves run about 5F warmer than the main compartment, which is normal but worth knowing if you store delicate produce there. The ice bin is also smaller than older GE side-by-side units, so big-party hosts may need to top it off manually.
Why this fridge stands out
It combines the largest capacity in our roundup with the four-door flexibility that lets you convert a section between fridge and freezer on demand. For large families or anyone who entertains often, this is the most efficient big-capacity French door.
What to consider before buying
Make sure your kitchen doorways and hallways are wide enough for a 36.75-inch wide, 388-pound unit. Delivery and installation typically requires two people and careful leveling of the four doors.
6. KoolMore 30-Inch Counter Depth French Door – Quietest Inverter in a Compact Footprint
Pros
- Whisper-quiet inverter compressor
- ENERGY STAR with 4 Star BEE
- Counter-depth flush fit
- Door alarm for efficiency
Cons
- No cheese or meat drawer
- Recessed handle shows fingerprints
- No built-in ice maker
The KoolMore 30-Inch Counter Depth French Door earned the highest average rating in our entire lineup at 4.6 stars, and the most consistent praise in owner reviews is for how quiet it runs. The inverter compressor ramps up and down so smoothly that several buyers mentioned they had to check the display to confirm the fridge was actually on.
The 465 kWh per year figure is strong for a French door, and the ENERGY STAR certification plus 4 Star BEE rating confirm it. The 18.5 cu. ft. interior is split between 6 door bins, adjustable glass shelving, and two humidity-controlled crispers.
The counter-depth 30-inch footprint fits flush with standard cabinetry, which is rare at this price tier. The door-open alarm is a small but useful feature: it prevents the energy waste that comes from leaving a fridge open while unloading groceries.
The two minor complaints are the lack of a dedicated cheese or meat drawer and the absence of a built-in ice maker. If you entertain often, plan to add a countertop ice maker. The recessed handle indentation also shows fingerprints, so keep a microfiber cloth handy.
Why this fridge stands out
It pairs the highest owner rating in our roundup with one of the quietest inverter compressors we saw in a counter-depth French door. For open-plan apartments where fridge noise travels, this is the pick.
What to consider before buying
There is no factory ice maker, so factor in a portable unit if you use a lot of ice. The fingerprint-prone handle is also worth knowing if you have small kids who like to touch the front of the fridge.
7. Antarctic Star 20.3 cu. ft. French Door – Best for RVs and Office Break Rooms
Pros
- ENERGY STAR certified with inverter compressor
- Multi-Air Flow even cooling
- Built-in ice maker and water filter
- Door-open alarm saves energy
- 90 degree door opening for tight spaces
Cons
- Smaller capacity than full-size units
- Limited color options (Silver/Grey only)
- Actual width slightly larger than listed
The Antarctic Star 20.3 cu. ft. French Door is the standout pick for off-grid and solar homes. The inverter compressor and Multi-Air Flow system keep the average draw low, and the built-in ice maker, water filter, and door-open alarm all help reduce wasted energy in a setting where every watt matters.
The 90-degree door opening is a thoughtful feature for tight spaces: it lets you place the fridge near a wall without the door blocking access to the shelves. The spill-proof LED lighting is also a small upgrade that makes cleaning easier.
Owners highlight the fast cooling, the quiet inverter operation, and the door alarm as the most useful features. Several buyers mentioned using this fridge in RVs and tiny homes where the lower draw makes a real difference on solar battery banks.
Color options are limited to Silver and Grey, and a few buyers noted that the actual unit is slightly wider than the listed dimensions. Measure your space carefully before ordering.
Why this fridge stands out
The combination of an inverter compressor, Multi-Air Flow, and door-open alarm gives you tighter control over energy use, which matters when every watt on your solar battery bank counts. For off-grid and solar homes, this is the most efficient mid-size French door.
What to consider before buying
Confirm the actual width fits your space, and verify your inverter and battery bank can handle the startup surge of the compressor. Most 2000W pure sine wave inverters handle it without issue, but it is worth checking.
8. GE GYE22GYNFS Counter Depth French Door – Best Counter-Depth Value From GE
Pros
- Counter-depth flush fit
- ENERGY STAR qualified
- Showcase LED lighting
- Fingerprint-resistant stainless finish
Cons
- Some reports of cooling failures at 1-2 years
- Ice maker can be tricky to operate
- Display above dispenser hard to read
The GE GYE22GYNFS brings a 22.1 cu. ft. counter-depth French door to the mid-tier price tier, with a fingerprint-resistant stainless finish and Showcase LED lighting that makes everything inside easy to find. The EnergyGuide lists 665 kWh per year, which translates to a moderate annual operating cost at the national average rate.
The space-saving ice maker is built into the door to free up interior shelf space, and the anti-bacterial filter helps keep the air inside cleaner. The adjustable shelving supports tall items like wine bottles, which is a small but useful detail.
Owners appreciate the built-in look at a price well below premium brands like Sub-Zero or Thermador. The fingerprint-resistant finish holds up well over time, and the LED lighting is one of the brightest in this price range.
The most consistent complaint in reviews is reliability: a small percentage of buyers report complete cooling system failure within the first two years. The display above the water dispenser is also hard to read in low light. Both are minor for buyers who get a working unit, but worth knowing.
Why this fridge stands out
It delivers the counter-depth built-in look at a price point well below premium European brands, with strong LED lighting and a fingerprint-resistant finish that holds up to daily use.
What to consider before buying
Check GE’s warranty terms and consider an extended warranty if you want peace of mind. Also confirm your kitchen can accommodate the 345-pound unit and 31.25-inch depth with the door open to 43.37 inches.
9. LG LF30S8210S 4-Door French Door – Best Large-Capacity Convertible Drawer
Pros
- 29.6 cu ft cavernous capacity
- ENERGY STAR certified
- Middle drawer converts between fridge and freezer
- Smart features with Multi-Air Flow
Cons
- Bottom freezer drawer feels flimsy
- Non-inverter compressor
- Door seals may wear before 2 years
The LG LF30S8210S is the largest fridge in our roundup at 29.6 cu. ft., and it uses a four-door French door design with a middle drawer that converts between fridge and freezer modes. For holiday cooking and big-party hosting, the convertible drawer is a real convenience.
The EnergyGuide lists 709 kWh per year, which sits on the higher end for our lineup but is reasonable for nearly 30 cu. ft. of capacity. The Multi-Air Flow cooling system keeps temperatures even across the large interior.
Owners love the cavernous interior, the convertible middle drawer, and the bright LED lighting. Many cite a smooth delivery experience and appreciate the Wi-Fi controls.
The two recurring concerns in reviews are the bottom freezer drawer, which feels flimsy and can wiggle side-to-side, and the door seals, which some buyers report deteriorate before the two-year mark. The non-inverter compressor is also worth noting if you want the smoothest efficiency curve.
Why this fridge stands out
The convertible middle drawer is a unique feature that lets you add freezer space temporarily during the holidays and convert it back to fridge space for everyday use. For buyers who cook for big gatherings, this is the most flexible large-capacity pick.
What to consider before buying
Inspect the door seals on arrival and check the freezer drawer mechanics before the return window closes. LG’s warranty covers parts and labor for one year, so report any issues early.
10. Summit 48-Inch French Door Kit – Best Built-In Alternative to Sub-Zero
Pros
- ENERGY STAR certified at 380 kWh/year
- Counter-depth 23.75-inch profile
- Significant savings vs Sub-Zero
- Two humidity crispers plus two meat drawers
Cons
- Composed of two 24-inch units joined by grill
- Glass shelves can bow under heavy loads
- Very tall 83.75-inch height
The Summit 48-Inch French Door Kit is the most efficient built-in-style refrigerator in our roundup, with an EnergyGuide figure of just 380 kWh per year. That is lower than several standard-depth French doors with bigger interiors, thanks to the efficient bottom-freezer pair design.
The kit combines two 24-inch bottom-freezer refrigerators with a decorative top grill to create a 48-inch built-in look that mimics premium brands like Sub-Zero at a fraction of the cost. The counter-depth 23.75-inch profile fits shallow kitchens where standard-depth units will not.
Owners value the energy efficiency, the counter-depth fit, and the two humidity-controlled crispers plus two meat drawers. The touch control system and Super Freeze setting are nice premium touches, and the absence of a built-in ice maker is a plus for buyers who prefer long-term reliability over convenience features.
The kit is two separate 24-inch refrigerators joined by a grill, not a single welded unit, so the two halves can slide apart on smooth floors. Summit does not include a mechanical joining mechanism. Glass shelves can also bow under heavy loads like multiple gallon jugs.
Why this fridge stands out
It delivers the look and feel of a premium built-in refrigerator at a much lower price point, and it does so with one of the lowest kWh figures in our entire roundup. For shallow kitchens and premium kitchen remodels, this is the most efficient built-in option.
What to consider before buying
Confirm your ceiling height can accommodate the 83.75-inch tall unit, and plan to secure the two halves to each other and to the wall to prevent sliding. The lack of an ice maker is intentional for reliability, but factor in a separate ice source if you entertain often.
Buying Guide: How to Choose the Best Energy Efficient Refrigerator?
This section covers everything you need to pick the right fridge and avoid the trade-offs nobody talks about. We will start with the configuration question, then walk through efficiency metrics, features, and reliability.
Match the Style to Your Household
Top-mount freezers are the most efficient style and the lowest kWh per cubic foot. Choose one if your priority is the smallest possible electric bill and you live in a household of one to three people.
Bottom-freezers and French doors are slightly less efficient but offer better everyday ergonomics, since fresh food sits at eye level. Pick one of these for families of three or more who cook frequently.
Side-by-sides are the least efficient common style. The narrow doors force you to open both halves for large items, and through-the-door dispensers add a 14 to 20% energy penalty. Only choose side-by-side if narrow door clearance is a must.
The 16 to 20 Cubic Foot Sweet Spot
According to Constellation, the most energy efficient refrigerators are usually 16 to 20 cu. ft. Smaller fridges use less total energy but have less insulation per cubic foot. Larger fridges use more total energy but spread that draw over more capacity. The 16 to 20 cu. ft. range hits the efficiency sweet spot for most households.
If you live alone or with one other person, an 18 cu. ft. top-mount is the cleanest answer. If you have a family of four or more, jump to a 22 to 28 cu. ft. French door with an inverter compressor to keep the per-cubic-foot efficiency reasonable.
Read the EnergyGuide Label Correctly
Every new refrigerator sold in the US has a yellow EnergyGuide label showing estimated yearly electricity use in kWh and the estimated annual operating cost. The kWh figure is the number to compare across models, since electricity rates vary by state.
At the national average electricity rate of about 16 cents per kWh, a 400 kWh/year fridge costs a moderate sum annually to run, while a 700 kWh/year fridge costs about 50% more. That difference adds up substantially over a 10-year lifespan.
The Reliability vs Efficiency Trade-Off
An appliance repair professional quoted on Reddit claimed that Energy Star compressors are “half the size, run continuously, have less power to maintain temp, and will break down sooner.” It is a real concern echoed across r/Appliances threads, and it is worth a candid response.
Modern ENERGY STAR compressors are smaller than older single-speed units because inverter technology lets them ramp up and down smoothly instead of running at full power and shutting off. The total energy delivered is similar or lower, and the wear pattern is gentler because there are no hard on/off cycles. Consumer Reports repair rate data shows that ENERGY STAR certified refrigerators do not have higher failure rates than non-certified models overall.
What the Reddit observation captures is real for a specific failure mode: undersized compressors in some budget models that struggle to maintain temperature under heavy load. The fix is to choose a fridge with a higher-rated compressor than your typical usage demands, especially if you live in a hot climate or open the door frequently.
Skip the Dispenser to Save Energy
Through-the-door ice and water dispensers add 14 to 20% to annual energy use, per Constellation. The heating element that prevents the dispenser from freezing, the extra insulation cuts in the door, and the increased cold-air loss every time the dispenser is used all add up.
If efficiency is your top priority, choose a fridge without a dispenser, or one with an internal dispenser like the LG LRFLC2706S that does not require a heated door panel.
Off-Grid and Solar Pairing
For off-grid homes, the fridge is the single largest 24/7 load on the battery bank. Choosing a low-draw model matters more than any other appliance decision. Our top picks for solar homes are the Kenmore 18.1 cu. ft. top-mount at 367 kWh/year and the Summit 48-Inch kit at 380 kWh/year. Both sip less than 1 kWh per day on average.
If you need a French door for capacity, the KoolMore 30-Inch at 465 kWh/year and the Antarctic Star 20.3 cu. ft. with its inverter compressor are the strongest solar-friendly picks. See our beverage refrigerator guide for secondary cooling that helps reduce door openings on the main fridge, and our portable car refrigerator guide for travel and RV options that run on 12V.
2026 Rebates and Tax Credits
ENERGY STAR certified refrigerators may qualify for rebates from your local utility, and some states offer additional incentives for high-efficiency appliances. The federal Energy Efficient Home Improvement Credit covers 30% of the cost of qualified ENERGY STAR appliances, up to a generous annual cap. Check ENERGY STAR Rebate Finder for state-specific offers before you buy.
Frequently Asked Questions
What brand of refrigerator is the most energy efficient?
ENERGY STAR certified models from Samsung, LG, and GE consistently lead efficiency rankings, with models like the LG LTCS20020S and top-mount Kenmore 4661342 typically consuming 350 to 550 kWh annually, which is less than running a 60-watt light bulb constantly. Among the 10 models we reviewed, the Kenmore 18.1 cu. ft. top-mount at 367 kWh/year was the lowest.
Which fridge is the most energy efficient?
The most energy efficient refrigerator is any ENERGY STAR certified top-mount freezer in the 16 to 20 cu. ft. range. The Kenmore 18.1 cu. ft. top-mount uses about 367 kWh/year at the national average electricity rate. For buyers who need French door capacity, the KoolMore 30-Inch at 465 kWh/year is the next-best option.
Which type of refrigerator is the most energy efficient?
Top-mount freezer refrigerators are the most energy efficient style, using 10 to 25% less energy than French door or bottom-freezer models. The compressor sits at the bottom of the cabinet, so the freezer on top stays farther from the heat source, and the simpler single-door cooling path wastes less cold air. Popular Mechanics, Constellation, and r/AskEngineers threads all confirm this ranking.
What fridge uses the least electricity?
ENERGY STAR certified top-mount freezers in the 16 to 20 cu. ft. range use the least electricity, typically 350 to 450 kWh per year. The Kenmore 18.1 cu. ft. top-mount at 367 kWh/year is one of the lowest in our roundup. The Summit 48-Inch kit at 380 kWh/year is the most efficient built-in-style option we reviewed.
Is an ENERGY STAR certified refrigerator worth it?
Yes. ENERGY STAR certified refrigerators are at least 9% more efficient than the federal minimum, and they can save roughly 50 to 120 dollars per year on electricity, especially in high-cost states like California, New York, and Hawaii. Over a typical 10-year lifespan, that adds up to 500 to 1,200 dollars in savings, which more than covers the typical 30 to 150 dollar price premium for the certified model.
Final Verdict: Which Energy Efficient Refrigerator Should You Buy?
After comparing 10 ENERGY STAR certified refrigerators across every configuration, our top recommendation is the Kenmore 18.1 cu. ft. Top Mount Refrigerator. It has the lowest kWh figure in our roundup at 367 per year, the strongest configuration for efficiency, and a 4.1-star average rating from 263 owners.
For buyers who need a premium French door, the Bosch 800 Series delivers dual compressor efficiency in a counter-depth package. For off-grid and solar homes, the Antarctic Star 20.3 cu. ft. French Door with its inverter compressor and door-open alarm is the smartest pick. Whatever style fits your kitchen, choosing an ENERGY STAR certified model is the single best way to cut your refrigerator’s share of the household electric bill, which sits at about 13.7% of total use.
