Your son may also be right about your fridge being an energy hog. Typically, a 10-year-old refrigerator can use as much as twice the energy that a new Energy Star qualified fridge uses. That translates to an extra $40 or more on electric bills each year. However before replacing your refrigerator, you can find out how much power it uses with a simple plug-in meter. Efficiency Vermont loans these meters at no cost and can help you to interpret your results. This will enable you to know how much lower your electric bills could be with a new fridge.
