General Information 3 Definition of Electrical Terms A watt (W) is a unit of electrical power. Its abbreviation is W. It represents the amount of electricity required to power a light bulb, an appliance, or other electrical equipment. Watt is a product of volts multiplied by amps. Watts = volts x amps A kilowatt (kw) is 1,000 watts. It is commonly abbreviated as kw. The prefix kilo is the Greek word for thousand. A kilowatt-hour (kwh) is a unit of electrical energy equal to one kilowatt used for one hour. Its abbreviation is kwh. For example, a 1,000 watt appliance running continually at full load for one hour will consume one kwh of energy. Also, a 100 watt light bulb left on for ten hours will consume one kwh of energy. An ampere (amp) is a unit for measuring the strength of an electric current. Its abbreviation is amp. Circuit breaker panels contain breakers of different capacities. Electric ranges usually require 50 amp breakers, electric water heaters and clothes dryers require 30 amp breakers, and convenience outlets and lighting circuits require 15 to 20 amp breakers. The maximum wattage that a 15 amp breaker should carry is 1,380 watts (80% of its rating). The maximum wattage a 20 amp breaker should carry is 1,840 watts (80% of its rating). 15 amps x 115 volts = 1,725 watts 80% of 1,725 = 1,380 watts A volt is a unit of electrical pressure. Pressure is the force at which electrical charges move through conductors. In most homes, 120-volt service is supplied to all wall outlets and lights. Large appliances (electric ranges, water heaters, clothes dryers and air conditioners) are supplied 240-volt service. Some apartment buildings or condominiums are supplied with 120/208 volt service. If you are purchasing a new range, clothes dryer or large air conditioner, be sure to check the voltage supplied to your home so you can match the appliance voltage with your service voltage. An Energy Efficiency Ratio (EER) is the ratio of the net cooling capacity output, in Btu/h, to the total rate of electric input, in watts, under designated operating conditions EER is commonly used for room air conditioners and small split systems. A Seasonal Energy Efficiency Ratio (SEER) is the total cooling output of an air conditioner during its normal annual usage period for cooling in Btu/h divided by the total electric energy input during the same period in watt-hours. SEER is commonly used for large split systems, central and packaged air conditioners. An Energy Factor (EF) is a measurement of overall efficiency in terms of energy output compared to energy consumption over a 24-hour usage cycle. The efficiency of an electric water heater is indicated by its energy factor. Energy factor is always greater than zero, but less than one. The higher the energy factor, the more efficient the appliance.
General Information 4 Understanding Your Electric Bill Why Electric Bills Vary Monthly Billing Periods Electric bills may vary due to the length of the billing period, which can range from 30 to 33 days. Be sure to look at this figure and not just the total dollar amount when comparing monthly bills. Lifestyle Changes and Activities Your use of electricity will fluctuate monthly even if the number of days in the billing period is the same. A new appliance, a change in lifestyle, a new baby, or visiting family or guests can all affect your monthly bill. Overnight guests may contribute to high energy use through increased meal preparation, loads of laundry, and bathing. Weather On cloudy days, you can expect to use more electricity due to increased lighting. On warmer days you may use more electricity with extra use of air conditioners and fans and more trips to the refrigerator/freezer for cold drinks and ice. Vacation Your bill may be lower after taking a vacation. If it is not, check the dates of the billing period. Do they coincide with the days you were away? Many electric appliances continue to work even when you are on vacation. Fuel Cost Fuel cost fluctuates. Any increase or decrease in cost will be reflected in your power bill. Why Your Electric Bill Is Not the Same as Your Neighbor s Each family has its own unique needs for electricity. Neighbors with similar electric bills are not very common even if the homes, family size and number of appliances are about the same. The interests and life style of each family is different. Their use of electricity will vary according to habits and activities. Some families cook more, use more hot water, and operate appliances more often than others. Other families may use energy more efficiently. Electricity use also varies according to the age, type, size and efficiency of appliances. These differences are reflected in each household s monthly electric bills. Your bill will rarely, if ever, be the same as your neighbor s.
Buying Appliances 5 Shop and Compare: Life-Cycle In the world of appliances, the best buy is not necessarily the least expensive model or the one with the highest efficiency. Calculating and comparing the life-cycle cost of different models can help identify the best buy for your money. The life-cycle cost of an appliance is the combination of its purchase price and the annual operating cost over its useful lifetime. To determine Life-Cycle Cost for an appliance, you ll need to know: The purchase cost (the price you paid from the store plus any finance charges). Any rebates or tax incentives that may be available. Average cost per kwh for residential customers. (GPA s Average residential rate as of September 2013 was 29 cents per kwh). The yearly energy cost to operate the appliance. (Check the EnergyGuide label or see pages 16 for Calculating Operating Cost). The estimated life of the appliance in years (see table below). The discount factor, a number that adjust for inflation and for the fact that a dollar spent today does not have the same value as a dollar spent in the future. See the table below for the discount factor, then use this formula to determine life-cycle cost. (Purchase Price Rebate) + (Annual Energy Cost x Estimated Lifetime x Discount Factor) = Life-Cycle Cost DISCOUNT FACTORS FOR LARGE APPLIANCES Appliance Estimated Life (Years) Discount Factor Electric Water Heater 13.83 Gas Water Heater 13.83 Refrigerator-freezer 20.76 Freezer 20.76 Central Air Conditioner 12.84 Room Air Conditioner 15.81 Range-Oven 18.78 Clothes Washer 13.84 Clothes Dryer 18.78 Dishwasher 12.84
Energy Guide Labels Buying Appliances Understanding EnergyGuide Labels 6 The EnergyGuide label is required to be placed on all appliances by the manufacturers. The label provides information about energy consumption, and shows you how much energy an appliance uses compared with similar models. Keep in mind that the numbers are averages: actual costs will differ somewhat depending on how you use them. The EnergyGuide label shows: 11. Maker, model number, and size of the appliance. 22. Estimated yearly operating cost (based on the national average cost of electricity), and the range of operating costs for similar models. 33. The ENERGY STAR logo indicates that this model meets strict criteria for energy efficiency. 44. Estimated yearly electricity consumption. 55. Key features of the appliance and the similar models that make up the cost comparison range. You ll find this label on refrigerators/freezers, water heaters, dishwashers and clothes washers. It is not used for clothes dryers or ranges/ovens. 4 5 1 3 2 EnergyGuide Label: Air Conditioning Here is a sample of an Energy Efficiency Rating EnergyGuide for air conditioning. Labels with EER ratings are used on room air conditioners and those with SEER Ratings are used on central air conditioning systems. This type of EnergyGuide label shows: 11. The type of appliance and its description and size. 22. Manufacturer, the model number and the capacity. 1 2 33. Energy efficiency range. 3
Energy Guide Labels 7 EnergyGuide: Lighting Facts Label You ll find a new label on light bulb packages: the Lighting Facts label. The Federal Trade Commission is requiring the label on all light bulb packages to help consumers easily compare energy-efficient light bulbs. The FTC now requires online retailers to post the label for any product with an EnergyGuide or Lighting Facts label. The EnergyGuide and Lighting Facts labels help you understand both the purchase price and the operating cost when shopping for new appliances or lighting. The FTC now requires online retailers to post the label for any product with an EnergyGuide or Lighting Facts the label. The label includes: 1 Brightness, measured in lumens 2 Estimated yearly energy cost (similar to the EnergyGuide label) 3 Lifespan 4 Light appearance (from warm to cool) 5 Energy used, measured in watts You can use the information on these labels to help estimate how much of your energy bill is going to lighting. Estimate your family s lighting use by figuring the total wattage of lights in each room and the length of time the lights are on each day. (See page 15 to learn more about lumens ). 1 Note: GPA s Average residential rate as of September 2013 was 29 cents per kwh. 2 3 4 5
ABCs of Air Conditioners 8 Selecting the Right Unit The air conditioning load is one of the largest contributors to a household s electric bills, but it has the potential for big energy savings. The energy consumption of an air conditioner depends on several factors: hours of use size, type, efficiency, and condition of the equipment. Three types of air conditioners used in homes: Room. Cools a single room. The unit is mounted in a window or through the wall. Split System. Cools one or more rooms. The compressor is placed outdoors and the (evaporator) fan coil unit is placed indoors. The two are connected by refrigerant lines. These units are quieter than room air conditioners and do not take up window space. Split air conditioners are mounted on the ceiling, floor, or wall. Central. Cools the entire house. An air distribution system carries cool air to all rooms in the house. A properly-sized air conditioner is important. An air conditioner that is too big for the space wastes energy and may not dehumidify the room(s) properly. The result is a cold and clammy feeling in the house. An undersized air conditioner will not cool adequately. There are a number of factors to consider when selecting the correct size air conditioner for your home. Factors include square footage of the rooms(s) to be cooled, height of ceiling, insulation of roof/walls, window area, direct sun, occupants in the area, outside temperature and humidity. Check with your air conditioning retailer or contractor to select the proper size. Tips for buying an air conditioner: Select a high efficiency air conditioner. An air conditioner s operating efficiency is measured by its Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER). They can be found on their EnergyGuide labels. To see if the unit you re choosing is the best buy, perform the life-cycle cost calculation (on page 5) and compare. Shop for a multiple-speed air conditioner. Compressors with more than one speed can match the cooling load required and maximize energy efficiency. Consider an energy-saver setting to cycle the fan on and off in conjunction with the compressor, rather than having the fan running constantly.
ABCs of Air Conditioners 9 Tips for Energy Efficient Air Conditioners Set the thermostat to the highest comfortable temperature (78 F). If you re going to be away for several hours or more, close the windows, doors, and draperies, and set the air conditioner s thermostat higher or turn the unit off. Install the outdoor compressor unit in a shady area to keep the condensing coil cooler and running more efficiently. If possible, place it where maximum circulation is available. Avoid unshaded locations on the west side of the home because the sun will strike the unit when it needs to work the most in the late afternoon. Maintain your air conditioner by cleaning the filter regularly and by keeping the outdoor unit free of dirt, grease, and debris. Replace filters that look worn. Insulate and weatherstrip windows and doors in the area to be cooled for maximum energy savings. Block out the sun s rays with curtains, drapes or blinds, and close off unused rooms. Shade windows with trees, shrubbery or awnings. Landscaping also improves the beauty of a home. Consider buying a programmable thermostat for your air conditioning system. You can program the thermostat to automatically adjust the cooling temperatures according to your schedule. Of course, you can adjust a manual thermostat yourself, but the convenience, comfort and energy savings of a programmable unit may be worth the cost. Use ceiling fans or regular fans rather than air conditioners when possible. Fans do not remove heat from the room, but they can provide a cooling effect by circulating air. They are less expensive to operate than air conditioners. Remember to turn the fan off if no one is in the room.
ABCs of Water Heaters 10 Electric and solar water heaters, insulation wraps Electric water heating is one of the largest energy users in the average home electric bill. For a family of four to five, the estimated energy use for an electric water heater is about kwh a month (up to 64 gallons of hot water a day). Your water heater energy use may be more or less than this. Your family s monthly kwh consumption is dependent on your family s size, the frequency of hot water use, and the water heater s efficiency, size and type. Types of Water Heating Systems Electric The most commonly used in Guam, electric water heaters contains one or two electric heating elements which heats the water in the storage tank. When the water in the storage tank reaches a preset temperature, the heating element turns off. Because heat escapes through the walls of the storage tank, the heating element periodically turns on to maintain the temperature. Solar Using the sun s energy to heat water, solar water heaters cost more to purchase than electrical units, but the operating cost is significantly lower because the sun s energy is free. Electricity may be used to operate pumps and provide backup had during long periods of cloudy weather. A well-designed and properly sized solar water heater can reduce water heating costs by 80% to 90%. Heat Pump A heat pump works the same way as an air conditioner. It takes heat out of the surrounding air, but instead of throwing the heat away outside, it pumps it into the water tank. A heat pump can be mounted on its own water tank or to your present tank. Heat pumps are about 50% more efficient than conventional electric water heaters. Buy the Right Water Heater by Matching First Hour Rating to Needs Select a water heater with the right size tank for your family. If the tank is too large, you ll be paying for heating extra water. If it is too small, you may regularly run out of hot water. To select a properly-sized water heater, choose a unit with a first hour rating equal to the gallons of hot water used during the peak period when your family s hot water requirements are high. The first hour rating shows how much hot water a heater can provide in one hour starting with a full tank of cold water. The water heater s first hour rating can be found on its EnergyGuide label. Check the Energy Factor Compare different models by using the EnergyGuide labels before buying to get a high efficiency unit. The efficiency of a water heater is indicated by its Energy Factor (EF). The higher the EF, the more efficient the water heater.
ABCs of Water Heaters 11 Tips to wisely use and save energy Repair leaking faucets. A leak of one drop per second can waste about 2,000 gallons of water a year. A leaking hot water faucet wastes both water and up to 400 kwh a year. Cover the water heater tank with an insulation blanket if the surface feels warm. The added insulation will retain the heat and save on your energy costs. Install low-flow shower heads if you have a standard shower head that allows water to flow at 4-6 gallons per minute. Low-flow shower heads reduce the flow rate to 2.5 gallons per minute. This will reduce your use of hot water and your energy cost in water heating. You will barely notice the difference if you buy a good quality, well-designed low flow shower head that mixes air and water at high pressure. Lower the setting of your water heater to 120 F, unless you have a dishwasher without a booster heater. Take short, 5 minute showers to reduce the use of hot water. Avoid taking tub baths. Tub baths use over 25 gallons of hot water. Cover or close the drain and fill the basin and sink, rather than let water run while shaving or doing dishes by hand. Turn the water heater circuit breaker off if no one will be home for more than two days in a row. Install a water heater timer. It can reduce and control your electric water heating costs.
ABCs of Refrigerators/Freezers 12 New Refrigerators are Easier on Energy Bills The cost of the energy needed to operate refrigerators, freezers, and refrigerator-freezer combinations is one of the largest of any home appliances. The operating cost of refrigeratorfreezers varies considerably depending on the size, type of defrost system, door style and age. Today s refrigerators and freezers use less energy and are significantly more energy efficient than older units. New units often use less kwh per year than older units. Newer models have improved insulation, compressors, motors, door seals, and larger condenser coil surface areas. The different types of defrost systems Manual Frost must be removed manually from the refrigerator/freezer when it becomes ¼-inch thick. Turn the setting dial to off or defrost to allow the frost to melt and loosen so that ice and water can be removed by hand. Generally, manual systems are found on refrigerator/freezers of less than 15 cubic feet in capacity with only one door. Designed for storage of fresh food, this type of unit has a small compartment for freezing ice cubes and short-time storage of already frozen food. Since it does not have a 0 F freezer section, it should not be used to store anything but ice cubes for any length of time. It cannot keep ice cream, frozen meat or other foods frozen solid. Partial Frost is removed automatically from the refrigerator section, but must be removed manually from the freezer section. A partial automatic defrost refrigerator-freezer usually has two doors with separate refrigerator and freezer sections. Automatic Frost is removed automatically in both the refrigerator and freezer sections. A fan circulates cold air to help maintain a more uniform interior temperature. The automatic defrost refrigerator-freezer has two or more doors and the freezer section may be on top, the bottom, or alongside the refrigerator section. Buying Refrigerators and Freezers Select the right size refrigerator-freezer that meets your family needs. An oversized refrigeratorfreezer will result in wasted space and energy. Undersized models have inadequate food storage and may lead to extra trips to the store. Compare different brands of refrigerator-freezers by using the EnergyGuide labels. These labels are your guide to savings, but keep in mind that the units must have the same type of defrost system, overall cubic foot capacity, and freezer section capacity for a good comparison. A manual defrost refrigerator is slightly more efficient, but since as little as ¼-inch thick ice will impair its efficiency, you are probably better off with an automatic defrost. Refrigerators with a top and bottom door are more efficient than the side-by-side door model. This is because top and bottom refrigerators have less are to insulate. Chest Freezers (top loading) are usually more efficient and cost less to operate than the upright (front loading) models. Air does not spill out when the door is opened.
ABCs of Refrigerators/Freezers Tips for Energy Efficient Refrigerators/Freezers 13 It often pays to replace a refrigerator near the end of its expected life with a new, more efficient model simply on the basis of energy savings. If you buy a new refrigerator, get rid of the old one. Plugging it in just in case can cost you several hundred dollars a year in electric bills. Clean refrigerator coils regularly. Located on the back or underside of the refrigerator, the coils can be cleaned by using a specifically designed brush or vacuum cleaner nozzle. To reach the bottom-mounted coils, snap off the front grill at the base then reach under with a brush or vacuum cleaner nozzle. Remember to unplug the refrigerator before you begin cleaning coils. Give your refrigerator room to breathe. Allow at least three inches of space between your refrigerator and the wall. The circulation of air helps the coils radiate heat better. Keep our refrigerator away from heat sources. Locate your refrigerator well away from stoves, windows with direct sunlight, dishwashers, and hot water heaters. Warm air from a heat source makes your refrigerator work harder and increases its energy use. Defrost manual and partial defrost freezers when frost/ice builds to 1/4-inch thick. A buildup of ice on the coil inside the unit makes the compressor run longer to maintain a cold temperature. Allow hot food to cool before placing in the refrigerator. Hot food will raise the temperature in the unit and increase its energy use. Thaw frozen food in the refrigerator. While thawing it helps keep the refrigerator cool. Open the refrigerator-freezer door only as often and only for as long as necessary. Replace worn seals. Leakage of cold air wastes energy. Cover or seal all liquids and moist foods before placing them in the refrigerator. Moisture from uncovered food can cause an automatic defrost refrigerator-freezer to use more energy.
ABCs of Lighting 14 (Illustration: US Department of Energy) Choices in Energy-Efficient Lighting The US Department of Energy estimates that the average household dedicates about 10% of its budget to lighting. Switching to energy-efficient lighting is one of the easiest and fastest ways to cut your energy bills. The most popular light bulbs available are energy saving incandescent (Halogen), compact fluorescent lamp (CFL), and light-emitting diodes (LED). Although the cost more to purchase than traditional incandescent bulbs, over their lifetime energy-efficient lights will save you money because they use less electricity. LED Lighting LED bulbs are rapidly expanding in household use. ENERGY STAR-qualified LEDs use only about 20%-25% of the energy and last up to 25 times longer than traditional incandescent bulbs. They come in a variety of colors. Some are dimmable or offer convenient features such as daylight and motion sensors. In addition to standard screw-in bulbs, you ll find LEDs in desk lamps, kitchen under-cabinet lighting, and even strings of holiday lights. CFL Lighting CFL bulbs last about 10 times longer and use about 25% of the energy of traditional incandescent bulbs. A typical CFL can pay for itself in energy savings in less than 9 months and will continue to save you money each month. You can buy CFLs that offer the same brightness and colors as traditional incandescent bulbs. Some CFLs are encased in a cover to further diffuse the light and provide a similar shape to traditional incandescent bulbs. Note: CFLs contain a very small amount of mercury and require special handling if they are broken. CFLs should be recycled at the end of their lifespan. Many retailers recycle CFLs for free. Visit epa.gov/cfl for cleanup and safe disposal steps. Halogen Incandescent Halogen or Energy-Saving Incandescent light bulbs are simply energy-efficient incandescent bulbs. They can last up to three times longer than traditional incandescent light bulbs. Halogen incandescent come in a wide range of shapes and colors and can be used with dimmers.
ABCs of Lighting 15 Tips for Energy Efficient Lighting Turn lights off when you leave the room. Turning a light off and on will NOT use more electricity, but can reduce bulb life. Dust all light bulbs, lamps and other fixtures regularly. A layer of dust affects your lighting. Replace inefficient incandescent bulbs in your home with Halogen, CFL or LED bulbs. When replacing incandescent bulbs from recessed light fixtures, use energy-efficient bulbs that are rated for that purpose. For example, the heat buildup in downlights will significantly shorten the life of spiral CFLs. ENERGY STAR-qualified fixtures are available in many styles, distribute light more efficiently and evenly than standard fixtures, and some offer convenient features such as dimming. Controls such as timers and photocells save electricity by turning lights off when not in use. Be sure to select products that are compatible with the energy-efficient bulbs you want to use. Dimmers save electricity when used to lower light levels. Be sure to select products that are compatible with the energy-efficient bulbs you want to use. Keep your curtains or shades open to use daylight instead of turning on lights and decorate with lighter colors that reflect natural and artificial light. A New Way to Shop for Light: Lumens In the past, we bought light bulbs based on how much energy, or watts, they used. Wouldn t it make more sense to buy lights based on how much light they provide? When you re shopping for energy saving light bulbs, you can choose the brightness you want by comparing lumens instead of watts. A lumen is a measure of the amount of brightness of a light bulb. The higher the number of lumens, the brighter the light bulb. If you re replacing an inefficient 100 watt bulb, look for an energy-saving bulb that puts out about 1600 lumens. To replace a 60 watt bulb, look for an energy-saving bulb with about 800 lumens. Traditional Bulbs Energy-Saving Bulbs 100 W 1600 Lumens 60 W 800 Lumens
Cost of Running Appliances 16 Calculating Operating Cost You can estimate how much it costs to run your appliances by performing the following: Step 1 Convert the appliance wattage to kilowatts. Divide the wattage by 1,000. kw = watts 1000 Step 2 Multiply the kilowatts by the number of hours the appliance is on per day. kwh per day = kw x number of hours per day Step 3 Next, multiply the kwh used per day by 30 days: kwh per month = kwh per day x 30 days This will give you the kwh/month use for the appliance. Step 4 To calculate the appliance s operating cost, multiply the kwh/month by GPA s Average residential. GPA s Average residential rate as of September 2013 was 29 cents per kwh. Operating cost of appliance per month = kwh/month x.29 per kwh The Energy Use Guide on the following pages provides the wattage for various home appliances. Use the typical wattages from the chart or check your appliance s operating manual or labeling to estimate the running cost.
Cost of Running Appliances 17 Energy Use Guide The following chart lists appliances and their estimated monthly kwh use for a household of four. Use this chart as a guideline only. The typical wattage listed in this chart is a representative figure that may differ from the appliances you have in your home. The frequency of use is an estimate that may also differ from your family s use due to differences in lifestyle and family size. To create an estimate of how much an appliance is costing to operate it in your home, multiple the Estimated Monthly kwh time by the local average residential rate. GPA s Average residential rate as of September 2013 was 29 cents per kwh.
