Consumer Reports warns that “keeping your old fridge when you buy a new one is a costly mistake.” http://www.consumerreports.org/cro/news/2015/07/that-extra-refrigerator-is-running-up-your-utility-bill/index.htm
If your refrigerator or freezer is more than 10 years old, it could be using as much as four times the electricity newer models consume. In 2001, refrigerators accounted for about 14% of all electricity usage in American homes.
Through the Energy Star program, the U.S. Department of Energy certifies new appliances that are especially energy-efficient. The website lists specific models and helps you calculate savings:

PECO will pick up an old, working fridge, pay you $40 for getting rid of it, and even grant a rebate on a new Energy Star model. Check the PECO website for details:
