Do you have a second refrigerator in your garage or basement? If so, it's got plenty of company. About 34% of American households have a second refrigerator, according to the U.S. Department of Energy, a number that's more than doubled over the last 20 years.
That's not cool when you consider that many of these devices are 10 years old or older, and very inefficient by today's standards. While technology advances have made today's refrigerators more efficient than ever, the growing trend of homeowners buying a new model and keeping the old is negating those efficiency gains.
