Help conserve some energy by raising the temperature in your refrigerator. Instead of 35 degrees (F), adjust the setting to 37-38 degrees (F). If your refrigerator doesn't have a thermometer, buy one at the hardware store for a couple dollars. You know your refrigerator setting is too low when the stuff toward the back of the unit starts to freeze.
Raise the temperature of your freezer from -3 degrees (F) to 0 degrees (F).
