Pull the fridge forward an inch or two.
In many kitchens, refrigerators are pushed back as close to the wall as possible in order to eke out a few more inches of floor space. Those few inches are really expensive.
If your refrigerator is pushed back as far as possible, pulling it forward one inch can reduce the energy usage of the refrigerator by as much as 40%, and you’ll barely notice the difference in your floor usage. Subsequent inches help, but aren’t quite that effective.
Stick a thermometer in your fridge.
Ideally, the temperature in your refrigerator holds pretty steady around 37 to 40 degrees Fahrenheit (3-5 C). We keep ours at almost exactly 38, and it’s almost perfect for us.
If you keep it below 37 degrees, you’re pushing up against the freezing point of water, which can affect food quality and burns a lot of extra energy. If you keep it above 40 degrees, it can affect food quality in a different way, leading towards spoilage. The range between the two is optimal – and it’s also optimal for refrigerator efficiency, since devices are designed to run in this range.
How can you be sure you’re hitting that sweet spot? Get out a thermometer, put it in a glass of water, then put that cup in your refrigerator for 24 hours. Check the temperature afterward – that’s the true temperature of your fridge. Adjust upward and downward as needed – you might be surprised how much your temperature is off.
A freezer has a different optimum temperature – 0 to 5 F (-18 to -15 C). You can get this temperature by putting your thermometer between two frozen items for 24 hours.
Chuck your refrigerated leftovers.
Ah, the refrigerated leftover. Inevitably, some of those items wind up getting pushed to the back and forgotten, left there to slowly decompose, become a potential breeding place for yeasts and molds, and potentially contaminate other foods.
So chuck ‘em. One easy way to do this is to have a handful of washable markers near your fridge. Doodle on any new item with a color for each day – say, purple for Monday, red for Tuesday, etc. Then, when you’re glancing in the fridge on Sunday, you know you can chuck anything with a red or purple mark on it without thinking at all.
Just mark on the Saran wrap, aluminum foil – even on the rim of a plate. Once you get into the routine, it works really well, makes leftover cleanup really easy, and keeps nasty things from growing in your fridge.
