(continued ...) Before I end this article about temperature, I want to mention a wild card. Refrigerators that have an egg shelf integral to the top of the door are a bad idea. Do you have one? If so, first that tells me your refrigerator is old enough that it likely needs replaced regardless of the energy measures we've talked about. Eggs spoil easily and even though the egg shelf is convenient, it exposes eggs to warm air each time the door is opened. Eggs should be in a tray on a lower shelf and they will last safely for weeks.
