Start by unplugging that older extra refrigerator in the garage or basement. Older-model refrigerators cost you an average of $150 per year to run. Make sure your kitchen refrigerator is in a cool place, away from direct sunlight and heat-generating appliances that can make it work harder. Keep it no colder than about 35 to 38°F, with plenty of air circulation behind it. Don’t stand with the door open; grab what you need quickly and shut the door. Make sure the door seals fit tightly against the doorframe.
