By law manufacturers must disclose the energy efficiency of their appliances, rated A to G. These are usually displayed prominently in showrooms. The better the rating, the more energy efficient the appliance is - good for both the environment and your pocket.

Added features such as ice making and drinks dispensers can all add to the appeal of certain models. Ice making is an option on many American style fridge-freezers, sometimes available without opening the door, as are cold water dispensers. Zoned models offer several storage areas, all at different temperatures, designed to keep a variety of foods fresh for longer. Most manufacturers now offer adjustable shelf heights and storage units which simplify food storage.

When you do have to shop for a new appliance, look for the Energy Star label. Energy Star appliances have been identified by the U.S. Environmental Protection Agency and DOE as being the most energy-efficient products in their classes. They usually exceed minimum federal standards by a substantial amount.
