The most energy-efficient models are typically 16-20 cubic feet. Generally, the larger the refrigerator, the greater the energy consumption. Models with the freezer on top tend to use less energy than those with freezers on the bottom or side-by-sides. Refrigerators with fewer doors reduce the air leakage.
Models with the freezer on top tend to use the least energy (versus bottom freezers or side-by-sides). Consider buying a refrigerator with fewer doors. Fewer doors reduce the air leakage. To maximize your savings, minimize the number of doors and pay attention to cool air you can feel when you shut the doors.
In the energy efficiency battle of bottom-mount freezer vs. side-by-side fridges or top-mount freezer vs. side-by-side fridges — yes, it does matter where that freezer sits: The most energy efficient refrigerator style is a top-mount freezer refrigerator.
A 4-star refrigerator consumes less power and is more energy-efficient than a 2-star model, resulting in lower electricity bills and reduced environmental impact.
Modern refrigerators are designed to use up to 40% less energy than models made just 10-15 years ago, thanks to advancements in insulation, compressors, and cooling technologies.
Which refrigerator brand is most reliable? All three of the appliance experts we spoke to for this roundup said Whirlpool and LG were the most reliable refrigerator brands due to their durability, reliability and ease of repairs. Samsung and GE were also mentioned by our experts as high-quality fridges.
A home refrigerator's power consumption is typically between 300 to 800 watts of electricity, or between 3 and 6 amps and about 120 volts. Importantly, refrigerators generally have a much lower "running" wattage than their stated average wattage – this is because they cycle on and off throughout the day.
An upright freezer has a front-mounted door like a refrigerator and shelves that allow for easy organization. While a chest freezer typically requires more floor space, it's usually more energy efficient, since the door opens from the top and allows less cold air to escape.
Our Top Pick: LG produces excellent refrigerators that perform well in our tests and receive high satisfaction ratings from consumers, including our survey participants. The Smart French Door Refrigerator with Dual Ice Maker stands out for its simple, user-friendly design and customizable features.
In 24 hours, a refrigerator can use between 1 to 2 kWh (units) of electricity. Energy consumption depends on factors such as the fridge's size, energy rating, and how frequently the door is opened.
Hair dryers, ovens, and space heaters use very few kilowatt hours and even refrigerators are energy friendly. This is especially true of newer refrigerators, which consume only 30 kilowatt hours per month.
For example, overloading the fridge with too much food can put extra strain on the motor, which will cause it to work harder and potentially fail sooner. Similarly, frequently opening and closing the fridge door can also lead to premature wear and tear.
Energy ratings run from A-G, with A being the most energy efficient and G being the least. And the more energy efficient your fridge, the less power it uses. Good for the planet and for cutting your energy bills.
Small, mini-fridges require less power than full-sized kitchen refrigerators.
Your fridge should run from around 35% of the day to around 85% of the day.
Generally, the larger the refrigerator, the greater the energy consumption. The most energy-efficient models are typically 16-20 cubic feet. Consider purchasing a refrigerator with a top freezer. Models with the freezer on top tend to use the least energy (versus bottom freezers or side-by-sides).
The truth is that older appliances were often built with sturdier materials, like good ol' fashioned metal, instead of flimsy plastic. This means that they can withstand wear and tear much better than modern appliances.
The national average price of electricity hovered around $0.14 per kWh (it shot up to $0.16 in late 2022) and the average home's total consumption is 10,632 kWh a year, which totals $1,452.12 yearly. So, in other words, your fridge accounts for a bit more than 10% of the average home's total electric bill.
Multiply the number of amps listed on the fridge's nameplate by the voltage (usually around 120). Then, because the compressor only runs about 30% of the time, divide the total wattage by 3. This number gives you the average running wattage of your refrigerator per hour.
Your usage
Frequent or prolonged door opening can place added pressure on the compressor because it lets more warm air in when you open the door. This means your fridge and freezer will need to use extra energy to replace the cold air that flows out every time the door is opened.
