When it's time to get a new fridge, many people relegate the old one to the garage as a backup. Want to save about $150? Recycle it instead. Since the refrigerator is one of the biggest users of energy in the home, having an extra adds about 10 to 20 percent to your electric bill -- or about $150 annually. Recycling is pretty easy: Many electric companies offer a free service where they will come to your home and take away your old fridge. It will get recycled, and the Freon gas inside will also be safely removed.
