Introduction – Cooling and Energy Efficiency
An energy-efficient freezer uses less energy while maintaining the temperature to keep food safely frozen. These are typically marked with an Energy Star certification and must meet certain energy usage criteria the EPA and Department of Energy set.
We Analyzed 363 Freezers And Found The Most Energy Efficient Freezers
We obtained and used our methodology to analyze a list of the Energy Star certified refrigerators from the EPA website.
There were three types of refrigerators included: upright, chest (that lay horizontal), and compact. We included all three types in our analysis. We didn’t simply look for freezers with the lowest energy usage – we used a special metric of kWh of energy to cool each cubic foot of space.
That way you won’t just get compact freezers which naturally use less energy for the trivial reason that the volume they cool is much smaller than larger freezers.
Top 7 Most Energy Efficient Freezers
The refrigerators are given by the manufacturer and a model number. The model number contains asterixes at the end which mean that multiple models have the same starting letters and numbers but differ in ending letters and numbers. The asterixes are wild card characters to indicate that the same stats about efficiency are shared across a bunch of models.

We Use “Kilowatt Hour Per Cubic Foot” Used As The Metric Of Efficiency
This leads us to the way we define efficiency. We assess energy efficiency of a freezer by the amount of electrical energy needed to cool down a cubic foot of space.
It’s not just how much energy a freezer uses, it’s also how much you can store in them! We calculated the kilowatt hour per cubic foot of space. Because many models for a single brand was represented, we also collapsed the results so that only the best model for each brand is represented.
This increases the diversity of brands and increases our choice.
New freezers have advanced thermostat and temperature control technology, allowing for more precise management of the freezer’s internal temperature.
In addition, some models may have functions such as “vacation mode” or “quick freeze,” which temporarily adjust settings to save energy when the freezer is not in regular use.
Choosing an energy-efficient model can reduce your overall energy consumption and lower your carbon footprint.
Note that our methodology automatically eliminated all the compact freezers because they are inefficient on a kWh per cubic foot basis. And of the top 10, 3 are upright and 7 are chest freezers.
There seems to be a preference or propensity for the horizontal freezers to be better at retaining cold. Below the top 7 you can see our full analysis of all 73 freezers!
Top 73 Most Energy Efficient Freezers
Although in our analysis we ended up analyzing 73 brand models for their energy efficiency, we only have space to talk about 7 in detail and add the specs for another 10 above. Here we show you what the statistical distribution of efficiencies look like.
On the left are the very efficient freezers which include the GE, Crosley, Frigidaire models. Their efficiencies are all less than 25 kWh per year per cubic foot.
In fact, looking across, the efficiencies don’t get much worse except at the very end when we reach the compact freezers. At this point, the inefficiency rises sharply to 75 kWh per year per cubic foot and even over 175 kWh per year per cubic foot.
The simple conclusion is that most of the large size freezers are efficient, and there’s not much difference between them. Just stay away from the really bad ones that are over 40 kWh per cubic ft, which constitute about ~20 brands.
However, if you are aiming for the ultra efficient, then go with the ones that we identified, provided you’re able to use the space. If you can’t use the space, calculate what is the minimum size you need and go for that. The inefficiency will rise a bit but not much.
The Benefits Of Using An Energy Efficient Freezer
The first benefit of using an energy-efficient freezer is lowering your monthly energy bills. The U.S. Department of Energy reports that refrigerators and freezers account for about 14% of a household’s total energy usage, so switching to an energy-efficient model can notably impact your bills.
Another benefit is helping to reduce greenhouse gas emissions and lessen your carbon footprint in the fight against climate change. The production and use of energy contribute to emissions, so using an energy-efficient appliance means fewer resources are needed to power it.
Additionally, most energy-efficient models also tend to be quieter and have better temperature control, leading to improved food preservation and less waste in the long run. Investing in an energy-efficient freezer benefits your wallet and the environment.
How Does An Energy-Efficient Freezer Work?
The first step is that the refrigerator or freezer uses insulation to keep the cold air trapped inside. This helps to reduce the amount of energy needed for cooling.
Next, the appliance uses a more efficient compressor that consumes less electricity. Lastly, it may have advanced temperature controls that allow precise adjustments instead of just turning the temperature up or down.
These factors work together to make the freezer more energy efficient, saving money on electricity bills and reducing carbon emissions. It’s important to note that proper maintenance and organization can also improve a freezer’s energy efficiency.
Be sure to clean out old items regularly and organize food for proper air circulation. Less energy is needed to freeze things and we can reduce the time to freeze ice cubes for example.
Overall, energy-efficient freezers offer numerous benefits regarding reducing energy consumption and protecting the environment.
Do Energy Efficient Freezers Really Make A Difference
Many people have switched to energy-efficient appliances, but does it make a difference? Does an energy-efficient freezer save you money and reduce your carbon footprint?
The answer is yes – and energy-efficient freezers can significantly save your electricity bill and environmental impact. Their wattage range from 40W to 50W, which saves a lot of energy when you compare it to an older model that uses 100W or more.
When looking for a new refrigerator or freezer, take note of its energy efficiency rating. This rating, measured in kilowatt-hours per year, tells you how much electricity the appliance will consume.
An energy-efficient model will have a lower rating, meaning it uses less electricity. And when it comes to your electricity bill, every bit counts.
Additionally, using less electricity means fewer emissions from power plants – benefiting both your wallet and the planet. Most energy-efficient freezers are also designed with better insulation and temperature controls, helping to preserve the food properly.
Combined with regular maintenance and proper organization techniques, an energy-efficient freezer can help you save money in the long run and play a valuable role in reducing your environmental impact.
Who Should Buy An Energy Efficient Freezer?
While energy-efficient products often come with a higher price tag, the cost savings, in the long run, make them worth considering for anyone looking to reduce their utility bills. However, certain groups may see even greater benefits from investing in an energy-efficient freezer.
For example, people living in hot climates will likely experience a larger reduction in their energy usage as their freezer works harder to keep food frozen.
Large households or those who frequently entertain and have constantly-stocked freezers can also see significant savings from switching to an energy-efficient model. And those who prioritize minimizing their environmental impact can rest easy knowing they are reducing their carbon footprint by using less electricity.
These are just a few examples of individuals who may benefit greatly from purchasing an energy-efficient freezer, but any conscious consumer should consider making the switch. Not only will you save money over time, but you’ll also be doing your part to preserve resources for future generations.
