Take the jolt out of your electric bill. Replace your old, inefficient appliances with Energy Star models, which use anywhere from 10-70% less energy than their conventional counterparts. This includes refrigerators, dishwashers, clothes dryers and more. In particular, appliances purchased prior to 1990 are considered extremely inefficient. Getting rid of them will help you step into the energy-saving era and even earn back part (or all) of the cost of your new appliances in monthly savings. So when it comes to your next oven range or microwave, it's okay to be concerned about labels. Pledge to be a star for the environment today.
