Energy Efficient Refrigerators

With recent improvements in insulation and compressors, refrigerators in general are much energy efficient. Consumers can realize further savings in energy consumption and costs with the purchase of an ENERGY STAR qualified refrigerator:

• Per U.S. Department of Energy requirements, to receive the ENERGY STAR label all refrigerators and freezers must be at least 20 percent more efficient than the federal standard (NAECA).
• In choosing ENERGY STAR qualified models over ones sold in the 1980s, a consumer’s energy bill will be reduced, on average, by $100 per year.
• ENERGY STAR refrigerators use less energy and aid in reducing the release of greenhouse gasses.

The National Energy Conservation Act (NAECA) dictates minimum standards for energy consumption in refrigerators and freezers, the specifics of which vary by configuration, automatic vs. manual defrost, and type of ice service.

Other Considerations in Purchasing Energy Efficient Refrigerators

Independent of the decision to buy on not to buy ENERGY STAR refrigerators, the following items should be considered in making a purchase decision:

• Review the Energy Guide label to determine and compare energy use and estimated annual operating costs with similar models.
• Seriously consider the top-mounted freezer option as these models typically use 10 to 25 percent less energy than the side-by-side models at a comparable size.
• Ensure an appropriately sized refrigerator recognizing that the most energy-efficient models range between 16 and 20 cubic feet.
• Recognize that automatic ice-makers and through-the-door dispensers increase energy use by 14 to 20 percent and typically raise the purchase price by $75 to $250.

Best Practices

There are a number of practices that can further reduce the amount of energy a refrigerator uses. These include:

• Keep the temperature of the refrigerator between 35 and 38 degrees Fahrenheit.
• Place the refrigerator away from major heat sources (e.g. oven, dishwasher, and direct sunlight)
• Allow sufficient room (a few inches) between the wall and the refrigerator to maintain air circulation.
• Routinely inspect the door seals to ensure they are airtight and replace them as necessary.
• Minimize the amount of time the refrigerator door is open.
