The freezer part of the refrigerator is actually the biggest user of energy of all kitchen appliances since it's on 24 hours a day, seven days a week. One easy way to help your freezer be as energy-efficient as possible includes keeping it as packed as possible with frozen foods. The residual chill from already-frozen food will keep the interior temperature cold, allowing the freezer to use less energy to stay cold. Common sense tips help, too: Only open the freezer to get exactly what you need -- so no idling in front trying to make up your mind -- and keep it set between zero and 5 degrees for maximum efficiency.
