Nine Tips for a More Efficient, Less Wasteful Refrigerator

From the Genius House Hacks archive.

It's easy to overload a refrigerator, which often leads to spoiled food. Between rising grocery costs, the amount the average family wastes each year on spoiled food, and the fact that fridges account for a meaningful share of household power use, there's a good case for a more sustainable approach to refrigeration. Here are some tips that help.

Choose an Energy-Efficient Refrigerator

A top or bottom freezer model uses less energy than a side-by-side, and a smaller fridge generally uses less energy overall.

Plan Shopping and Meals

Sticking to a shopping list helps avoid impulse purchases and unnecessary waste.

Arrange by Lifespan

Place items with shorter lifespans at the front and top shelf so they get used promptly, and regularly review freezer contents to prioritize older items.

Understand Expiration Dates

Most foods are still safe after their expiration or best-by date. If it looks, smells, feels, and tastes fine, it's likely still good.

Focus on Produce

Prep and store vegetables properly to extend freshness, and repurpose aging produce in soups, casseroles, stir-fries, or baked goods rather than tossing it.

Store Foods in Optimal Locations

Keep meats and seafood on the colder bottom shelves, and reserve warmer spots like the door for items such as milk. Adjust humidity settings in veggie drawers based on what's stored there.

Avoid Overloading

Overcrowding the fridge or freezer hampers efficiency, and packing in bulk items inefficiently can strain the appliance.

Plan for Leftovers

Store leftovers in transparent containers, ideally glass over plastic, to increase visibility and reduce the chance they get forgotten. Freeze leftovers after a few days, using ice cube trays for small amounts like tomato paste or lemon juice.

Close the Door and Maintain the Appliance

Minimize how often the door opens, since excessive openings make the fridge work harder. It also helps to vacuum the coils twice a year, check door seals regularly, keep the fridge between 37 and 39 degrees and the freezer at 0 degrees using a thermometer, and keep the unit away from direct sunlight and the stove.
