Appliance Guide Turn the Page To Turn On Energy Savings Using Appliances Efficiently, And Tips When Shopping For New Ones When talking about appliances, a big issue is how much it costs to run them. You can cut the energy usage of your appliances and save money with the tips in this booklet. All of them are practical suggestions, simple to use, and proven effective. You’ll be pleased to see how just changing little things can add up to big savings. We’ve also included some pointers for buying new appli- ances. It’s important to get a good deal, but your best buy may not be the appliance with the lowest price. The real cost of your new appliance includes purchase price and also the operating costs for as long as you own it. For example, if you’re buying a refrigerator, models of the same size can vary quite a bit in price. The cheaper refrigerator might cost $50 to $70 more each year to operate. On average, refrigera- tors have a useful life of about 15 years, so the unit that was cheaper to buy ends up costing $750 to $1,050 more to operate. In the long run, a more energy- efficient appliance can be the better value. This guide provides some useful information for getting the most efficiency out of your existing appliances and making informed decisions when choos- ing your new appliances. 1 Index 2 Understanding Electrical Usage Understanding Energy Efficiency 3 EnergyStar® Appliances Getting the Most From Your Existing Appliances, and Value-Smart Shopping Tips When Choosing New Ones 3 Refrigerators I For best efficiency from your refrigerator I Some things to consider when buying a new refrigerator 4 Air Conditioners I For best efficiency from your air conditioner I Some things to consider when buying a new air conditioner 5 Clothes Washers I For best efficiency from your clothes washer I Some things to consider when buying a new clothes washer 5 Clothes Dryers I For best efficiency from your dryer I Some things to consider when buying a new dryer 6 Dishwashers I For best efficiency from your dishwasher I Some things to consider when buying a new dishwasher 6 Small Kitchen Appliances 7 Home Entertainment 7 Lighting 8 Computers and Peripherals 9 Best Efficiency, Best Performance, Best Value Understanding Electrical Usage Use of electricity is metered and billed by kilowatt-hour, often written as kWh. Kilowatt-hour is a unit of measure for consumption of elec- tricity. It’s the amount of electrical energy needed to run a 1,000 watt device for one hour. But the same amount of electrical energy can also be used in longer or shorter periods of time. For example: I 1 kilowatt-hour = runs a typical 1,000-watt hair dryer for 1 hour I 1 kilowatt-hour = lights a typical 100-watt bulb for 10 hours I 1 kilowatt-hour = runs a typical 14-cu.-ft. refrigerator for about 10 hours The thing to remember is that one kilowatt-hour of electrical energy can be used fast or slowly, depending on the appliance. That’s also useful for understanding efficiency because electricity can be used more slowly or quickly by the same types of appliances. Again, let’s use refrigerators as an example. Comparing two 14-cu.-ft. refrigerators: I Refrigerator #1 – consumes 1 kWh every 10 hours I Refrigerator #2 – consumes 1 kWh every 11 hours The second refrigerator is more efficient because it runs for one extra hour on the same amount of energy. Understanding Energy Efficiency Energy-efficient appliances don’t look very different. This is because most of the differences are on the inside. Motors, pumps, valves, compressors, or electronic “smart” sensors that can improve efficiency don’t usually change the product’s looks. To help consumers, the govern- ment requires manufacturers to put EnergyGuide labels on refrig- erators, freezers, dishwashers, clothes washers, central air con- ditioners, room air conditioners, water heaters, and other appli- ances. Here’s how the labels look: All EnergyGuide labels show: The manufacturer, appliance type and model number Features and capacity or size, so you can compare models Estimates of the appliance’s annual energy use. The lower the number, the more efficient the appliance, and the less it will cost you to run. The range of efficiency for similar models An estimate of the annual cost to run this model. Use this for comparison purposes only, because your actual cost will vary. The efficiency claims are not just hype. Manufacturers must use standard test procedures developed by the Department of Energy to prove the energy consumption and efficiency of their products. So when you shop for an appliance, be sure to look for the EnergyGuide label. 2 A D B E C A B C E D 3 EnergyStar® Appliances Some appli- ances also feature the EnergyStar logo like the one shown here. These products have been designed to provide out- standing energy efficiency, so you cut usage and lower your energy costs. Be sure to check out whether EnergyStar appliances meet your needs.

Getting the Most From Your Existing Appliances, and Shopping Tips When Choosing New Ones When buying appliances, always check the EnergyGuide label for a comparison of energy efficiency with other models. Consider EnergyStar appliances for maximum efficiency and lowest operating costs. Refrigerators In most residences, the refrigerator uses more electricity than any other appliance. It can add up to nearly 15% of total energy usage. But some very inefficient older models may represent as much as 30% to 50% of the monthly electric bill. If your existing refrig- erator is more than 20 years old, buying a new one will save more than $100 in annual energy costs. For best efficiency from your refrigerator: I Position refrigerator away from direct sunlight, and heat sources like stoves. I Open door briefly, and close promptly to keep cold air in. I Store food in the refrigerator so air can circulate, but in the freezer, pack items tightly. I Set refrigerator temperature at 40 degrees Fahrenheit and freezer temperature at 0 degrees. I Make sure rubber gaskets on doors provide a tight seal. I Dust or vacuum condenser coils to keep them clean. Some things to consider when buying a new refrigerator: I Models with freezer compart- ment at the top use 7% to 13% less energy than side-by-side models. I Manual-defrost models use approximately half the energy of automatic-defrost refrigerators. To benefit from this superior efficiency, you must clean them manually when frost builds up to more than 1/4 inch. I Automatic ice makers and through-door dispensers increase energy use by 12% to 14%. I Models with an “anti-sweat” heater use 5% to 10% more energy. I Don’t buy a refrigerator that’s larger than you need. Air Conditioners An average air-conditioned home consumes more than 2,000 kilowatt-hours each year for cooling. High-efficiency A/C units can reduce energy consumption by 20% to 50%, and the most efficient air conditioners on the market are up to 70% more efficient than older room air conditioners. For best efficiency from your air conditioner: I Turn off your air conditioner when there’s no one home. For a cool interior when you return, buy a timer that can turn on the air conditioner half an hour before you get back. I Keep the air conditioner’s filter clean. I If you’re using only the room where your air conditioner is locat- ed, shut the doors to that room. I Keep interiors no cooler than 78 degrees. It’s an efficient setting that’s also comfortable. Moving to a colder temperature consumes more energy and costs more money. Going to 75 degrees costs 18% more, and a 72- degree setting costs 39% more! I Once a room is cool, shut off the air conditioner and use fans to keep comfortable. When the room warms up, cool it off with the air conditioner, then use fans again. Using this method can cut air-conditioner running time by 20% to 40%. Some things to consider when buying a new air conditioner: I Air conditioner capacity should be right for the room. Bigger is not better. A smaller unit running for an extended period operates more efficiently, and it’s better at dehumidifying the air than an oversized unit cycling on and off too frequently. I Measure the room you need to cool. Store personnel will help you choose the right capacity air conditioner. Here is a general guide: I Be sure that your home’s electrical system can meet the air conditioner’s requirement. Some models operate at 120 volts, but others require a 208-volt source. Check to make certain the new unit will be properly powered. I Air conditioners with built-in timers and thermostat setting features will help you trim energy usage. 4 Approximate room size 10’X15’ 16’X28’ 25’X40’ loft A/C capacity in Btu/hr 5,000 10,000 18,000 Clothes Washers Most of the energy used by clothes washers is for heating the hot water used to wash clothes.
