Why do some freezers with a better star rating use more electricity?
It’s important to remember that the Energy Star Rating is not actually based on the amount of electricity a freezer uses. Instead, it lets you know how efficient a freezer is at using electricity – this allows the rating system to take different freezer shapes and sizes into account. Obviously, a big freezer will use more electricity than a small freezer, but if it converts this energy more efficiently, it will receive a better rating.
