Keep a full refrigerator

This feature is only available to GreenYour members. Please sign-up.

When the door is open and warm air rushes in, the refrigerator’s motor will run to bring the temperature back down to the desired setting. If the refrigerator is well stocked, the temperature will not rise as quickly, hence reducing the demands on the motor and in turn reducing overall energy consumption.

Things to keep in mind

  • Two-thirds full is the magic ratio for top performance
  • Don't over-stuff the refrigerator. Air needs to circulate for optimal efficiency.
  • Throw out old leftovers once a week (just before garbage pick-up day) so you’ll have sufficient space for the food you want to keep.
  • If your refrigerator is low on food, fill containers with water to take up empty space.

Related refrigerator efficiency tips

  • Don't place hot food in the fridge or you will raise the air temperature and the motor will have to work harder to bring it down.
  • Cover liquids and foods. Uncovered foods release moisture, which causes the compressor to work harder.
  • Close the refrigerator door quickly. To cut down on your time in the fridge, assign foods permanent locations so you'll be able to locate them with ease.
  • Defrost your freezer. Don't allow frost to build up to more than one-quarter of an inch thick. When frost accumulates, it increases the amount of energy needed to keep the motor running.
  • Use a refrigerator that is the right size for your needs. If it's too large, it may often be empty, which wastes energy. If is IS time to purchase a new one, be sure to purchase the most energy-efficient model.

Keeping a full refrigerator helps you go green because…

  • The refrigerator operates more efficiently, using less energy and reducing greenhouse gas emissions.

Refrigerators use the most electricity of all appliances—almost five times more than the average television.[1] The production of electricity by coal-burning power plants—the most common method of electricity production in the US—releases greenhouse gases into the atmosphere. Therefore, when appliances operate efficiently, electricity use, and subsequent greenhouse gas emissions, are decreased.
