How do Energy Star appliances work?

Energy Star appliances work like any other appliance. Unfortunately, products that shouldn't be classified as Energy Star are all over the market. There was a Consumer Reports article a few years ago showing things like mops and brooms having Energy Star ratings. Until there is more direct rating from within the Industry instead of the Government regulations, the energy star rating is anyone's best guess. ANY manufacturer that make ANY product can apply for an energy star rating.
