Are freezers energy efficient?

Depending on the size, independent energy rating, and amount of contents stored in the freezer, each model will vary in regards to individual energy rating. By exercising a number of these tips, your freezing habits can become more energy and cost-effective: Avoid putting your freezer next to a heat source, such as a cooker or in direct sunlight, as this will cause your appliance to work harder to stay cool. Clean your freezer regularly, as this can eliminate any accumulation of dust which can also increase energy consumption. Don’t overload your freezer. Overloading your freezer prevents air from circulating freely throughout your appliance which, in turn, makes it work harder and use up more energy. By keeping it stocked, but not overloaded, you can freeze your food in a cost and energy-efficient manner.
