Freezing food is an essential, easy kitchen function but it's not quite foolproof. Next time you think "Oh, I'll just toss this in the freezer," remember these missteps. Setting the temperature too high. Zero degrees or even lower is the best temp for long-term frozen food storage, so set your freezer as low as it will go. And if you find that your ice cream gets too hard to scoop, store it on the door where the temperature will be the highest. Keeping the freezer nearly empty.

If you leave the door open a very long time the refrigerator will run full-speed all the time. Your empty-jug idea would work well both for normal use and for the rare case of doors being open for a long time. The heat capacity will scarcely be affected by the foam peanuts, since they're mostly air. They will slow down heat exchange with the outside, which could marginally reduce enrgy use if the refrigerator is opened often. Follow-up on this answer.

Given that everything else is equal model of fridge, temperature settings, external temperature, altitude , over a given duration of having the door closed, does it require more electricity to cool an empty refrigerator AND maintain that temperature, than a full one? In real-world cases there can be a difference though. The difference depends on when the refrigerator decides to cycle on and cool. If the fridge cycles on a timer or based on heat energy then there will be a difference due to the added heat capacity.
