The NJ Dept. of Environmental Protection has begun a new program in which old refrigerators or freezers that are not energy-efficient can be traded in for a $50 rebate. NJ residents must meet the criteria (listed here), which includes being a customer of a commercial, not municipal, electric utility company (Most Essex County residents use PSE&G). A new, more energy-efficient fridge or freezer can save you more than $100 a year on your electric bill, and is better for the environment. This handy little calculator tells you how much your current fridge or freezer costs to operate now, and how much you could save with one that qualified for Energy Star. Trading in your fridge or freezer is better for you and better for your town, and now comes with a $50 bonus! Why not?
