Where does all this money go? The cost of heating your home can represent 40% to 60% of your total energy bill. The chart below shows the breakdown of energy use by category and starts to give you a sense of where savings can be found. Reducing energy consumption by just 15% could save you over $300 a year in energy costs. 11% Heating & Cooling – 46% Water Heating – 14% 4% Lighting – 12% Appliances – 13% 13% 46% (Includes refrigerator, dishwasher, clothes washer and dryer) Electronics – 4% (Includes computer, monitor, TV and DVD player) Other – 11% 12% (Includes external power adapters, set-top boxes, ceiling fans, vent fans and home audio) 14% Managing Your Energy Budget Having a budget is always a good idea. But developing a budget starts with understanding your resource needs. Each month, you need food, clothing, transportation and energy to run your home. Understanding your energy usage is the first step to creating that portion of your budget. Inside this booklet, you’ll find many energy saving tips to help you manage your resources. This booklet contains ideas and suggestions on how you can monitor— and better control—your energy consumption. You may already be familiar with some of our energy savings suggestions; some may surprise you though. Individual lifestyle and energy use habits, number and age of occupants, as well as the size, design, levels of insulation and heating system in your home, all combine to determine how much energy you will use for heating. The statistics in this booklet are based on national averages. The wattage or energy usage and efficiencies of your appliances, your own use habits, as well as the size of your family will vary. So, keep this in mind when you’re reviewing your own energy use. Page 3 Energy Use and Savings Guide Understanding This Guide Listed below are terms and definitions that will be used throughout this guide. All numbers and costs included are a representation based on national average use with average Avista rates. Kilowatt Hours (kWh): We measure the amount of electricity in Watt hours. One kilowatt hour equals 1,000 Watt hours. The kilowatt hours on your bill equals the rate or speed of use (kilowatts) x the length of time electricity was used. Running a 5,000-watt (5 kilowatt) clothes dryer for 1 hour uses 5 kilowatt hours of electricity. Burning a 100-watt light bulb for 10 hours uses 1 kilowatt hour. Therms: Your use of gas is billed in units called therms. Therms identify the heating value provided by gas. One therm equals the heating capacity of approximately 100,000 wooden kitchen matches. Approximate Watts: The wattage is the consumption rate of electricity a device exhibits while operating. This energy consumption may occur when a computer is turned on, when a kitchen mixer is in use or when light bulbs are turned on in a light fixture. Monthly kWh Usage: The monthly kilowatt hour usage for each device is based on an assumed typical month of operation, estimating the hours the device is operating in conjunction with its power consumption as noted in the Watt rating. Annual kWh Usage: The annual kilowatt hour usage is an estimate of the yearly energy consumption in consideration of the Watts and hours of operation assumptions. In some cases, the season often creates just a few months of use per year. Estimated Monthly Cost: The estimated monthly cost is based on the energy consumption at $0.09 per kilowatt hour for electricity or $0.84 per natural gas therm. Page 4 Benefits of Natural Gas 1. Affordability: Natural gas costs less to use in your home than electricity. On average, electricity costs more than twice as much as natural gas. 2. Convenience and Reliability: Natural gas is piped directly into your home. It’s always there when you need it. 3. Comfort: Natural gas heat warms your home quickly compared to an electric heat pump by moving a small volume of hot air versus a large volume of warm air that can feel drafty. 4. Domestic Supply: Nearly 100% of the natural gas consumed in the U.S. is produced in North America with 90% coming directly from the U.S. 5. Energy Efficiency: Natural gas is highly efficient. About 90% of the natural gas produced is delivered to customers as useful energy. In contrast, only about 30% of the energy converted to electricity from natural gas reaches consumers. Where available, natural gas is increasingly the fuel of choice in today’s homes. Natural gas compares very favorably to other fuels. Below is a current snapshot of how natural gas compares to other fuels and some benefits to consider when choosing how to heat your home. BTU: The British thermal unit (BTU) is a measure of heat. MMBtu equals 1,000,000 BTU. A typical home uses 5 to 7 MMBTU’s per month in the heating season. Heating cost per million BTU in Washington and Idaho (April 2016) Efficiency Heating Cost per Month Natural gas furnace 80% $63.75 Natural gas furnace 94% $54.26 Electric resistance furnace or baseboard 100% $158.22 Electric heat pump 175% $90.41 Electric heat pump 225% $70.32 Propane furnace 80% $177.63 Propane furnace 94% $151.18 Electric resistance costs 2.5 times more than natural gas, propane 2.8 times more than natural gas, a heat pump backed by electric resistance heat is 1.4 times more than gas.

Page 5 Energy Use and Savings Guide Direct Use of Natural Gas You probably know about the comforts of natural gas—warm, even heat; precise temperature control when cooking; consistent hot water; and the cozy ambience of a natural gas fireplace. But did you know natural gas is the cleanest burning fossil fuel? As such, it plays a central role in emerging initiatives to help protect our environment. And while natural gas can be burned in turbines to produce electricity for our region (about 40% efficient), delivering it directly to your home for heating and cooking is the most efficient use of this resource (about 90 to 92% efficient). Information is based on national numbers and figures. Data source: Gas Technology Institute MMBtu: MMBtu describes a defined volume of natural gas as a commodity, essentially 1,000 cubic feet of the fuel in the pipe. Another common term for natural gas usage is the therm, the unit used in residential billing. Ten therms are equivalent to a single MMBtu of natural gas. For a typical home that uses natural gas for space and water heat, about 50 to 70 therms, or 5 to 7 MMBtus of natural gas would be consumed in one month. Page 6 Heating and Cooling Energy Saving Tips • On sunny winter days, open your draperies to get full benefit of sun shining through the windows. In summer, close the draperies to help keep out unwanted heat. • Fireplace dampers should be kept closed when you’re not using the fireplace. A chimney can draw off as much as 25% of the heated air in your house if the damper is left open. Safely block off unused fireplaces when possible. • When selecting an air conditioning unit, both room or central, check its Seasonal Energy Efficiency Ratio (SEER). The SEER indicates a unit’s relative energy efficiency. Most units are tagged with this information, or your dealer can help you determine the SEER. The higher the SEER, the better. A SEER of 13 or above is preferred, 18 or above is exceptional. • When selecting a heat pump, check its Heating Seasonal Performance Factor (HSPF). The HSPF indicates a heat pump’s relative annual heating efficiency. A higher HSPF of 8.5 and above will provide lower operating costs for heating. • Turn down the heat in winter. Keep your thermostat at or below 68° F; setting your thermostat three degrees lower in the winter can reduce your bill by about 10%. Reading Your Meter Electric and natural gas meters are not difficult to read and they can provide you with information about your energy consumption. Visit myavista.com/readyourmeter to learn more about how to read your meter. Page 7 Energy Use and Savings Guide Heating and Cooling Energy Saving Checklist FF Block drafts. Check caulking and weather stripping around windows and doors. If you see cracks, light, or feel a draft, make repairs where needed. FF Seal leaks. Ductwork exposed to outside air or in unconditioned spaces should be wrapped securely with insulation; joints and connections should be sealed with insulation tape. FF Check furnace filter. Check filters at least once a month; clean or replace them when dirty. FF Bring in a professional. A qualified serviceman should check heating and cooling equipment at the beginning of each season to ensure efficient operation. FF Use drapes or shade. Window coverings are one of the easiest ways to help insulate your house. Keep them closed on cold days and open on sunny ones. FF Use fans in the summer. Try using fans in the summer before switching on the air conditioning. Old A/C equipment can be equivalent to using 30 or more fans. If you must use your air conditioner, set it at 78° F; each degree over 78° in the summer will save you approximately 3% on your cooling bill. FF Program your thermostat. Adjust temperature settings according to a preset schedule. This way you can warm up or cool down your rooms when you know you’ll be awake or at home. Consider a Wi-Fi enabled smart thermostat that learns your settings.

If you have a dishwasher, check the manufacturer’s instructions for suggested temperature setting. Generally, residential water heaters should not exceed 140° F or be below 115° F. • Turn off electricity at your circuit breaker/fuse box before adjusting thermostats on the water heater for safety, or when you are going away from home for three days or more to save energy. • Turn gas water heater to pilot only if you are going away from home for a week or more. • Once every three months, drain a pail or two of water from the drain at the bottom of your water heater. This removes sediment and mineral deposits, which make your water heater less efficient. • Always use a sink stopper or dishpan rather than washing or rinsing dishes under running hot water. • Showers generally take less hot water than baths and dishwashers generally take less water than hand washing. • Buy ENERGY STAR appliances. • Consider a tankless natural gas water heater that reduces standby losses. Energy Saving Checklist FF Keep showers short. Try to keep your shower to no longer than five minutes. FF Adjust your temperature settings. Set your water heater at 120° F. FF Replace washers on faucets that drip. A leaky faucet can waste 2,500 gallons of hot water per year at a rate of one drip per second. FF Install a low-flow shower head. It can reduce your home water consumption as much as 50%, and reduce your energy cost of heating the water also by as much as 50%. No more than 1.5 gallons per minute.

Wattage measures only the amount of energy needed to light the bulb. Light actually given off is measured in lumens. The law now requires that manufacturers list the wattage, the lumen output and the approximate life span of each bulb on the package. The most energy efficient bulb is the one that gives off the most lumens per Watt. Compare bulb ratings by dividing lumens by Watts. • A 23-watt compact fluorescent lamp (CFL) will produce more light than a 100-watt incandescent bulb and can be used in kitchens, baths, laundry and work areas. • ENERGY STAR qualified CFL bulbs use 75% less energy than incandescents. • Light-emitting diode (LED) bulbs use up to 90% less electricity to produce the same amount of light as their traditional incandescent counterparts. • Only use dimming CFLs or LEDs in dimming sockets. • Light-colored ceilings reflect the light downward for better lighting efficiency. • Security lights are a wise precaution. Outside post lights and floodlights can be controlled by a photoelectric cell for automatic dusk-to-dawn lighting. • Automatic timers to turn lights on or off when you’re not at home are available at a reasonable cost. Energy Saving Checklist FF Turn it off. Turn off lights when you are not using them. FF Make the switch. Change out all regular incandescent lamps with ENERGY STAR qualified LED bulbs if they are used more than two hours per day. FF Keep bulbs clean. Dust can cut light output by as much as 25%. FF Dispose of your used bulbs properly. Recycle your old CFLs at a participating recycling center near you.

Energy Use and Savings Guide Major Appliances Refrigeration Energy Saving Tips • Choose a well-insulated, energy-efficient refrigerator with a separate door for the freezer compartment (that way, when removing an item from the freezer, you avoid opening the refrigerator door unnecessarily). • Don’t put warm foods directly into the refrigerator. Allow hot foods to cool, then refrigerate. Cooked meats, however, should be refrigerated immediately. • Cover all foods and liquids. In frost-free models, evaporation of the liquid will force the unit to work harder to remove the moisture. • Do not locate the unit near a heat source. • Check the tightness of your refrigerator door gasket by shutting a piece of paper in the door. If the paper slides out without resistance, your refrigerator may be leaking cold air. Consider replacing the door seals. • Every three months vacuum the condenser coils located at the bottom or rear of the refrigerator to remove accumulated dust. • Both the refrigerator and the freezer operate most efficiently when they are full, but not overcrowded. It takes more energy to keep air cold than it does to keep food or liquid cold. Be sure to allow enough space between foods and containers for air to circulate freely. Refrigeration Energy Saving Checklist FF Adjust the temperature. Set your refrigerator between 37 to 40° F and your freezer between 0 to 5° F. FF Keep fridge door closed. Know what you want out of the refrigerator before you open the door. An open door is wasted energy. FF Defrost freezer. Defrost when ice is ¼" thick. FF Clean refrigerator coils. Keep coils clean to keep your refrigerator in peak operating condition. They may be behind or below the fridge. FF Cover and wrap food. Uncovered foods and liquid release moisture, which makes the fridge work harder. FF Fill it up. A full fridge or freezer uses less energy. Fill with jugs of water to take up space.

If you must look, do so through the oven window. Or rely on your own thermostat and timer. (This will cut down on baking failures, too!) • The oven is a very inefficient toaster. It costs three times as much to toast bread in the oven as in a pop-up toaster. • Match the size of your cooking pans to the size of the surface units on your range so you won’t waste heat. Flat-bottomed pans receive heat directly and conserve energy. • When boiling water, bring the water to a boil on high heat, then reduce the heat to your cooking temperature. • Instead of heating water in an open pan, use a teakettle or microwave. • Food should always be cooked on the lowest possible setting. • Leave at least two inches between pans in the oven for proper heat circulation. Pans should not touch each other, the oven doors or walls. • If the kitchen is chilly, don’t use the electric range for heat. A small electric heater will do a much better job. • Thaw frozen foods before placing them in the oven. Putting a frozen roast directly in the oven requires one-third additional cooking time (microwave ovens can be used for quick thawing). • When using glass or ceramic dishes, you can lower the oven setting 25° F. • If your electric or gas range has a self-cleaning feature, clean it while the oven is still hot after removing a meal. Since a self-cleaning oven must be well insulated, it uses less energy for baking or roasting. Using the self-cleaning feature costs about 15 cents per use. Page 16 Major Appliances Range / Oven Energy Saving Checklist FF Keep racks clear. It’s tempting to line oven racks with foil to keep things clean, but don’t do it. The hot air needs to be able to circulate to cook food efficiently. FF Use lids. When cooking, lids keep heat and steam in and help food cook more quickly, which saves energy. FF Clean the burner pans on your stove. When clean, burner pans will reflect heat back up to pots and pans. FF Don’t peek. You lose heat every time you open the door or lift the lid. FF Use the smallest pans possible. It takes less energy to heat smaller pans.

You’ll use less hot water and save energy. • According to ENERGY STAR, you can save 5,000 gallons of water each year and $40 in energy costs using a dishwasher instead of washing dishes by hand. • One dishwasher load usually uses less hot water than three washings by hand. Dishwasher Energy Saving Checklist FF Fill it up. It costs exactly the same to wash one dish as it does to wash a full load of dishes. FF Scrape dishes instead of pre-rinsing them. Dishwashers made in the past five to ten years can clean even heavily soiled dishes without prerinsing. FF Use air-dry options. Keep your machine from using a heating element to bake your dishes dry and opt to air dry your dishes instead.

If your washer doesn’t have a partial load setting, let the machine fill to the desired water level, then turn the dial manually to begin the wash cycle. • When possible, wash and rinse clothes in cold water. However, hot water may be necessary for some types of wash loads, like baby clothes. • For heavily soiled clothes, use the soak cycle, or prepare the load for washing and then let stand in the water for 10 to 15 minutes before starting the wash cycle. • Keep your dryer exhaust vent clean. If clogged, it can lengthen drying time and increase energy consumption. • Select the correct drying temperature and time. Don’t over dry; in addition to wasting energy, over drying gives clothes a harsh feel and causes wrinkling. • Sort clothes by thinness to avoid running an additional cycle for only one or two slow drying items. • Vent your clothes dryer to the outside to reduce buildup of excess heat, moisture, and laundry chemicals. • Don’t overload dryer because clothes will take longer to dry. • Since an iron heats faster than it cools, first iron the fabrics that require lower temperatures, then work up to fabrics requiring a hotter setting. Laundry Energy Saving Checklist FF Select cold water. Hot water only needs to be used for very dirty loads. FF Only run full loads. The machine uses about the same amount of water whether you wash a full load or just one item. FF Hang it up. Instead of using the dryer, dry clothes outside in good weather—sunlight is free. FF Clean the lint filter after every load. Clogged filters drive up drying time and costs.

Use your big oven to bake complete meals, or to bake in quantity (perhaps to freeze for later). • A pressure cooker and a microwave oven can cut down on cooking time and, in many cases, on energy usage. • Keeping the inside of your microwave clean allows your food to cook more efficiently. Kitchen Electronics Energy Saving Checklist FF Smaller is better. For small meals, utilize the microwave, toaster oven, electric pans or other kitchen gadgets to avoid heating up the whole oven for one toasted cheese sandwich. FF Skip the oven.

These products use less energy without sacrificing quality or performance. • Electronics may continue to use power even when they appear to be off. The little glowing light means they are using energy—up to 10% of your annual electricity usage. You can make sure you’re cutting use by switching everything off with one power strip switch. • Don’t overload circuits by plugging too many electronics into one outlet. Family Room / Living Room Electronics Energy Saving Checklist FF Unplug it. Battery chargers or power adapters for devices like cell phones, eBooks and more may pull juice even when they’re not in use—don’t let them. FF Use power strips. Plug your video game consoles, stereo, DVD players and any other home electronics into a single power strip so you can switch it off and cut all power to items at once. FF Try “smart” power strips. They can help reduce your power usage by shutting down power to products that are not in use or that go into standby mode. Check Out Your Energy Use by Checking Out a Kill-A-Watt™ Meter Avista has teamed up with local libraries to make Kill-A-Watt™ meters available for checkout.

The energy used by one traditional C9 light bulb could power 140 LED bulbs. • LED lights function just as well outdoors as they do indoors. They are constructed in such a way that they are impervious to moisture, heat and cold. • Energy efficient holiday LED lights only add about two cents a day to your energy bill. • In addition to saving energy, ENERGY STAR qualified LED lights contain up to 50,000 hours of use, are cool to the touch which reduces the risk of fire, and are more durable than glass incandescent lights which means less risk of electrical exposure from broken bulbs. • Popular fan-driven inflatable lawn decorations ranging in size from 4' to 12' can add from $1.11 to $1.68 to your monthly bill if run for eight hours a day, or when used for 24 hours a day, the additional monthly cost would be from $3.34 to $5.05 per inflatable. • Be aware and watch for overhead power lines when installing outdoor lights. Seasonal Outdoor Energy Saving Checklist FF Check decorations. Before decorating, check all light sets for frayed wires, damaged sockets, or cracked insulation. If you find any defects, replace the entire set. FF Upgrade to LEDs. Replace your old holiday lights with LED light strings. Although they cost more initially, LEDs use a fraction of the energy of traditional holiday lights. Plus, they contain up to 50,000 hours of use. FF Use a timer. Plug your indoor and outdoor lighting displays into a timer set to run during the earlier evening hours. If you don’t use timers, unplug your lights when you go to sleep or leave home. FF Safety first. Unplug lights before watering the tree and keep cords and light sets away from the water.
