If your fridge is on the fritz, buying a new one can be better than repairing. Today’s models are much more energy-efficient than older ones. Compared to a conventional refrigerator built before 2001, for example, Energy Star models are about 40 percent more efficient. Consumer Reports' tests also show that efficiency diminishes somewhat over the life of the appliance. Over their life, new units will generally save enough energy to offset their purchase price.
