![]() And of the top 10, 3 are upright and 7 are chest freezers. Note that our methodology automatically eliminated all the compact freezers because they are inefficient on a kWh per cubic foot basis. 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.Ĭhoosing an energy-efficient model can reduce your overall energy consumption and lower your carbon footprint. New freezers have advanced thermostat and temperature control technology, allowing for more precise management of the freezer’s internal temperature. This increases the diversity of brands and increases our choice. 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. 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. We assess energy efficiency of a freezer by the amount of electrical energy needed to cool down a cubic foot of space. This leads us to the way we define efficiency. We Use “Kilowatt Hour Per Cubic Foot” Used As The Metric Of Efficiency These were all analyzed using the above method of energy needed to cool per cubic foot of space. To make it simpler, here we include a table that includes the 7 from above, and 3 more to make the top ten most efficient freezers. 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. 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. We included all three types in our analysis. ![]() There were three types of refrigerators included: upright, chest (that lay horizontal), and compact. We obtained data from Energy Star certified refrigerators from the EPA website. Important for those who want to understand how we got our results. Methodology: We Analyzed 363 Freezers And Found The Most Energy Efficient Freezers The calculated efficiency is 21.32 kWh per cubic ft. Beko freezers are known for their energy efficiency and have won several awards for their environmental credentials. The company produces a wide range of domestic appliances, and its freezers are available in a variety of sizes and designs. Beko freezers have been produced by the Turkish company Beko since the early 1990s – one of the largest appliance makers in Europe. It is certified by the CB to be 31% less energy use than the US Federal Standard. It has an annual energy use of 305 kWh/yr and has a US Federal Standard of 445 kWh/yr. It has a total volume of 14.3 cubic feet and an adjusted volume of 25.1 cubic feet. The Beko freezer is an upright freezer with automatic defrost. ![]() Our final entry, the 7th most efficiency freezer uses 21 kW like the 5th and 6th.
