Appliances account for about 20% of your household's energy consumption with refrigerators, clothes washers, and clothes dryers at the top of the consumption list. The first step in energy efficiency is using these appliances efficiently. Start the dishwasher when you have a full load. Set washing machine cycles to match the load. Use power strips on computers, TV's & stereos that consume electricty even when not in use, then turn off the power strip until you need the appliance. When you're shopping for appliances, think of two price tags. The first one covers the purchase price—think of it as a down payment. The second price tag is the cost of operating the appliance during its lifetime. You'll be paying on that second price tag every month with your utility bill for the next 10 to 20 years, depending on the appliance. Refrigerators last an average of 13 years; room air conditioners and dishwashers, about 11 years each; clothes washers, about 9 years. When you do have to shop for a new appliance, look for the ENERGY STAR label. ENERGY STAR products usually exceed minimum federal standards by a substantial amount. An ENERGY STAR qualified clothes washer can save you $550 in operating costs over its lifetime compared to a regular clothes washer. ENERGY STAR qualified washers are also better for the environment because lowering energy and water use means less air pollution from power plants and less water going to waste. To help you figure out whether an appliance is energy efficient, the federal government requires most appliances to display the bright yellow and black EnergyGuide label. Although these labels will not tell you which appliance is the most efficient, they will tell you the annual energy consumption and operating cost for each appliance so you can compare them yourself.
