If you cook a pot of rice for 1 hour, you use 1,000 watthours of electricity 1,000 watt-hours = 1 kilowatt-hour (kWh) How Much Electricity Do Appliances Use? Dishwashers Energy used is mainly for water heating Dishwasher Tips Long-Term Savings Tip When shopping for a new dishwasher, look for the ENERGY STAR label to find a dishwasher that uses less water and 41% less energy than required by federal standards. Refrigerators A new refrigerator with an ENERGY STAR label uses at least 20% less energy than required by current federal standards and 40% less energy than the conventional models sold in 2001. Refrigerator/Freezer Energy Tips Refrigerator/Freezer Energy Tips Refrigerator: 37°F to 40°F Freezer: 0°F to 5°F Refrigerator/Freezer Energy Tips Check freezer and refrigerator temperature with an appliance thermometer Refrigerator/Freezer Energy Tips Regularly defrost manual-defrost refrigerators and freezers Refrigerator/Freezer Energy Tips •Have tight door seals •Place a dollar bill in the door; you should be able to pull the bill out easily Refrigerator/Freezer Energy Tips Uncovered foods release moisture and make the compressor work harder Long-Term Savings Tip Other Energy-Saving Kitchen Tips 8 easy low-cost and no-cost ways to save energy in the kitchen Kitchen Tips Use cold water when using small amounts of water Kitchen Tips • If you need to purchase a natural gas oven or range, look for one with an automatic, electric ignition system. An electric ignition saves natural gas because a pilot light is not burning continuously. Kitchen Tips Gas appliances • Look for blue flames; yellow flames indicate that the gas is burning inefficiently Kitchen Tips Keep range-top burners and reflectors clean • Better heat reflection • Saves energy Kitchen Tips • Use a covered kettle to boil water • Match the size of the pan to the heating element Kitchen Tips •Use small appliances when possible •Use pressure cookers and microwave ovens when convenient Laundry 90% of the energy used for washing clothes in a topload washer is for • Ways to reduce the amount of energy used for washing clothes 1. Use less water 2. Use cooler water Laundry Tips • Wash in cold water using cold-water detergents whenever possible • Wash and dry full loads Laundry Tips Dry towels and heavier cottons in a separate load from lighter-weight clothes Laundry Tips • Use moisture sensors, if possible • Clean the lint filter after every load Laundry Tips • Periodically inspect your dryer vent to save energy and prevent fires – Use rigid venting material • Use cool-down dryer cycle to use residual heat Laundry Tips Consider air-drying Long-Term Savings Tips ENERGY STAR clothes washers Clean clothes using 50% less energy than standard washers Use 15 gallons of water per load, compared to the 32.5 gallons used by a new standard machine Spin the clothes better Long-Term Savings Tips Look for a moisture sensor when shopping for a new clothes dryer – Automatically shuts off the machine when your clothes are dry Clothes dryers do not have ENERGY STAR labels – Most use similar amounts of energy Major Appliance Shopping Guide Appliance Rating Natural Gas and Oil Systems Look for the FTC EnergyGuide label with an AFUE (Annual Fuel Utilization Efficiency) rating for natural gas- and oilfired furnaces and boilers. The AFUE measures the seasonal or annual efficiency. ENERGY STAR furnaces have a 90 AFUE or higher. Special Considerations Bigger is not always better! Too large a system costs more and operates inefficiently. Have a professional assess your needs and recommend the type and size of system you should purchase. Major Appliance Shopping Guide Appliance Rating Special Considerations Air-Source Heat Pumps Look for the EnergyGuide label that lists the SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) for heat pumps. The SEER measures the energy efficiency during the cooling season and HSPF measures the efficiency during the heating season. The ENERGY STAR minimum efficiency level is 13 SEER or higher. If you live in a cool climate, look for a heat pump with a high HSPF. ENERGY STAR heat pumps are about 20% more efficient than standard models. Contact a professional for advice on purchasing a heat pump. Major Appliance Shopping Guide Appliance Rating Special Considerations Central Air Conditioners Look for the EnergyGuide label with a SEER for central air conditioners. The ENERGY STAR minimum efficiency level is 13 SEER. Air conditioners that bear the ENERGY STAR label may be 25% more efficient than standard models. Contact a professional for advice on sizing a central air system. Major Appliance Shopping Guide Appliance Rating Special Considerations Room Air Conditioners Look for the What size to buy? EnergyGuide label Area (sq ft) Btu/hour with an EER (Energy Efficiency Ratio) for 100 to 150 5,000 room air 150 to 250 6,000 conditioners. The 250 to 350 7,000 higher the EER, the 350 to 450 9,000 more efficient the 400 to 450 10,000 unit is. ENERGY STAR 450 to 550 12,000 units are among the 550 to 700 14,000 most energy700 to 1,000 18,000 efficient products. Two major factors should guide your purchase: correct size and energy efficiency. If the room is very sunny, increase capacity by 10%. If the unit is for a kitchen, increase the capacity by 4,000 Btu per hour. Major Appliance Shopping Guide Appliance Rating Special Considerations Programmable Thermostats For minimum ENERGY STAR efficiency, thermostats should have at least two programs, four temperature settings each, a hold feature that allows users to temporarily override settings, and the ability to maintain room temperature within 2°F of desired temperature. Look for a the ENERGY STAR label and a thermostat that allows you to easily use two separate programs, one that can be programmed to reach the desired temperature at a specific time, and a hold feature that temporarily overrides the setting without deleting the preset programs. Major Appliance Shopping Guide Appliance Rating Special Considerations Water Heaters Look for the EnergyGuide label that tells how much energy the water heater uses in one year. Also, look for the FHR (first hour rating) of the water heater, which measures the maximum hot water the heater will deliver in the first hour of use. If you typically need a lot of hot water at once, the FHR will be important to you. Sizing is important—call your local utility for advice. Major Appliance Shopping Guide Appliance Rating Special Considerations Windows Look for the NFRC (National Fenestration Rating Council) label that provides U-values and SHGC (solar heat gain coefficient) values. The lower the U-value, the better the insulation. Look at the Climate Region Map on the ENERGY STAR label to be sure that the window, door, or skylight you have selected is appropriate for where you live. Major Appliance Shopping Guide Appliance Rating Special Considerations Refrigerators and Freezers Look for the EnergyGuide label that tells how much electricity, in kWh, the refrigerator will use in one year. The smaller the number, the less energy it uses. ENERGY STAR refrigerators use at least 20% less energy than required by federal standards. Look for energy-efficient refrigerators and freezers. Refrigerators with freezers on top are more efficient than those with freezers on the side. Also look for heavy door hinges that create a good door seal. Major Appliance Shopping Guide Appliance Rating Special Considerations Dishwashers Look for the EnergyGuide label that tells how much electricity, in kWh, the dishwasher will use in one year. The smaller the number, the less energy it uses. ENERGY STAR dishwashers use at least 41% less energy than required by federal standards. Look for features that will reduce water use, such as booster heaters and smart controls. Ask how many gallons of water the dishwasher uses during different cycles. Dishwashers that use the least amount of water will cost the least to operate. Major Appliance Shopping Guide Appliance Rating Special Considerations Clothes Washers Look for the EnergyGuide label that tells how much electricity, in kWh, the clothes washer will use in one year. The smaller the number, the less energy it uses. ENERGY STAR clothes washers use less than 50% of the energy used by standard washers. Look for the following design features that help clothes washers cut water usage: water level controls, “suds-saver” features, spin cycle adjustments, and large capacity. For double the efficiency, buy an ENERGY STAR unit. Summary
