“Many of you contact Idaho Power with questions about your bills, our services and how you can save energy in your home. The questions you ask are interesting and important. Here are answers to some questions that may be on your mind this time of year.”

Q: I’m on a limited budget. What can I do to keep my winter heating bills down?

A: These inexpensive options can help no matter how you heat your home: • Seal windows and doors with caulk or weatherstripping to reduce leaks and drafts. • Replace your most-used light bulbs with energy-efficient LEDs. • Install WaterSense® high-efficiency showerheads. • Set your thermostat as low as comfort and safety allow. • Reverse ceiling fans so they blow warm air up toward the ceilings and down the walls. • Close crawl space vents and, when not in use, fireplace dampers. • Use your oven efficiently. Bake many items at once or one right after another. • Wash full loads of laundry and dishes, and rinse in cold water.

Q: What upgrades save the most in energy costs?

A: Everyone can benefit from replacing inefficient light bulbs and showerheads. After that, each home is unique. Make a plan for your home. • According to the U.S. Department of Energy, replacing refrigerators and clothes washers more than ten years old may be worthwhile. • Sealing air leaks and adding attic insulation can be a good option for older homes. • Replacing single pane or metal-framed windows with new, efficient ones may pay off.

Finding Affordable Energy-Saving Products for Your HomeCover: Shane and India Humphreys are first- time home buyers who searched for the best energy efficient products for their new home.

“We decided to spend some money on a few things we thought would save us money in the long run,” Shane explained. That included upgraded spray foam insu lation, ENERGY STAR® appliances and LED lighting.

Shane used online cost calculators to learn how much energy LEDs would use in their new home and how long it would take to pay off the difference between the cost of LEDs and incandescent light bulbs; it was only three years. He also learned LED lights last about 25 years compared to the incandescent lights at two to three years.

“Many people probably haven’t even thought about how much en ergy their lights are using,” Shane said. “A lot of people still believe LEDs are not cost effective. It may not be the right decision for everybody, but for a lot of people, it’s a good option and will save money in the long term,” said Shane.

Questions Customers AskBy Theresa Drake, Manager of Customer Relations and Energy Efficiency

Use caution with space heaters. They use a lot of electricity, can be a fire hazard and will increase your bill unless they allow you to reduce the temperature in a large portion of your home.

Safety Tip

Building CodesSince 2002, Idaho has adopted energy codes on a three-year cycle. The first two cycles increased energy efficiency about five percent over the previous code. In 2009, code efficiency jumped by about 15 percent to where we are now. So if your home is 10 years old, it could be 20 percent less energy efficient than a new home. To increase your comfort and add value to your home, consider bringing your home up to the current standard.

Idaho Power’s online portal to your account gives you access to many resources. After you answer a few simple questions about your home (found in the Savings Center), you’ll get instant feedback on how your electricity use compares to other homes of similar size and occupancy. You’ll also see a chart showing where your electricity dollars may be going.

Have you ever wondered how your home’s energy use compares to other homes? Because there are so many variables, this can be a tough question to answer. Here are good ways to see how your home measures up.

New Lighting OptionsIf you’ve shopped for light bulbs lately, you know your options have changed. When considering which bulb is best for you, start by reading the Lighting Facts label on the package.

Idaho Power partners with retailers to offer special pricing on a variety of energy efficient bulbs. Look for the Simple+Smart logo at a retailer near you.

BrightnessFor years, people have chosen light bulbs by the watt, learning over time about how bright a typical 40-watt or 60-watt bulb is. But wattage only tells how much energy a bulb uses — not how bright it is.

With newer light bulbs designed to use less energy, wattage is no longer a reliable way to gauge a light bulb’s brightness. That takes lumens. The higher the lumens, the brighter the bulb.

Even if a package has watts (or a watt equivalent) listed on it, the brightness could vary. A bulb marked as a 60-watt equivalent could be anywhere between 750 and 850 lumens. Read the label and look at the lumens. Want a brighter bulb? Pick one with higher lumens.

Too Dim? Size and ShapeBefore you shop, look at the light fixture to get an idea of the size and shape bulb that will work best. If you like the current bulb, take it with you to the store to find a similar one.

ColorIf you’ve ever painted a room white, you know there are lots of shades of white. Just like paint, white light can vary from a warm reddish glow to a cool blue. Color is measured on the Kelvin (K) scale. Warm light, around 2700K, is similar to traditional incandescent light and is better for general lighting. Cool light, above 4100K, is brighter and provides more contrast — better for reading or work areas.

There used to be three basic choices of light bulbs — 60, 75 or 100 watts. Now, there are many choices.

Special FeaturesRead the label to make sure the bulb you buy works for your intended use. Not all bulbs work with dimmer switches, 3-way lamps, photocells, enclosed fixtures, recessed can lights or outside.

When fitting multiple fixtures of the same type, such as recessed can lights, it may be worth buying just a few bulbs at first, to ensure you find the right one for your needs.

Helpful HintBe cautious about using different bulb colors in a single fixture or room. When multiple lights are on, the difference may be distracting.

• Dimmer switches vary the light level and are easy to install. Make sure you choose a dimmable bulb that’s compatible.

• Timers can be inexpensive and keep light on for a set amount of time. Electronic versions can be programmed and adjust to daylight.

• Photocells sense changes in outdoor light levels so exterior lights turn on at dusk and off at dawn.

• Motion sensors turn lights on instantly when motion is detected and off when it isn’t. Newer models can gradually fade lights off.

• Occupancy sensors turn lights on when someone is in the room and turn the lights off when the room is empty.

• Vacancy switches require you to turn the lights on, but turn them off automatically if you forget.

Specialty Switches Make Saving EasyTired of reminding people to “turn off the lights?” Let technology do some of the work for you. It can even help save energy while the lights are still on. Here are some options:

Three types of lighting work together to light your home. They are ambient, task and accent lighting. Combining all three types (layering) creates a functional, beautifully lit room.

Ambient lighting refers to general lighting. Ambient light include sunlight, overhead lighting and lamps. Using natural daylight from south-facing windows has the added bonus of providing winter warmth.

Task lighting helps you perform specific tasks. A reading lamp at a desk or pendant lamps hanging over a kitchen island are examples.Task lighting should be free of distracting glare but bright enough to prevent eyestrain.

Accent lighting draws attention to a particular object. As a rule, it should be brighter than the ambient light to help draw attention to the area of interest.

Why Choose LEDs?LEDs may cost more upfront, but the benefits and long-term savings can pay off.

Lighter paint colors and glossy paints reflect more light and increase brightness in a room without using energy.

Helpful Hint

Layer Your Light

BESTBETTERGOOD

Outdoor lighting is a great way to help make your home safe and secure, especially as nights get longer. But outdoor lights use energy and are often left on for long periods. To stay safe and save energy, assess your lighting needs, limit the hours your lights are on and choose ENERGY STAR® bulbs.

Assess Your Lighting Needs• Trim trees and shrubs to get rid of

hiding places and reduce the need for extra lights.

• Evaluate dark areas around your home, garage or yard to decide where lights are needed.

• Select Dark Sky/neighbor-friendly lights. These direct light down where it is needed without lighting up the sky or shining in your neighbor’s window.

• Make sure your house number is well lit so in an emergency, first responders can find your house quickly.

Choose ENERGY STAR Bulbs• Purchase ENERGY STAR bulbs. They save

energy and meet stricter performance standards.

• Know your bulbs. Learn to look at the lumens rather than the watts. Lumens are the key to brightness; the more lumens the brighter the light.

• Use compact fluorescent lights (CFLs) or light emitting diodes (LEDs). These lights use up to 75 percent less energy and last longer than traditional bulbs.

• Read the label. Not all bulbs are rated for use outdoors or with specific sensors.

Limit the Hours of OperationUse automatic controls to make turning the lights off easy.

• Motion sensors are triggered by movement and turn lights on for a limited time.

• Photocells sense light levels and turn the lights on at dusk and off at dawn.

• Some new fixtures come with built-in sensors or photocells.

OUTDOOR LIGHTING: Stay Safe as It

Gets Dark Earlier

CFLs and LEDs require additional considerations to ensure a long life. If a bulb burns out earlier than you expect, ask yourself these questions.

• Was it an ENERGY STAR® certified bulb? ENERGY STAR bulbs must meet specific quality standards to earn the label.

• Was the bulb in an enclosed fixture? Light bulbs emit heat, warming the air around them. If a CFL is in a glass enclosure, a recessed can, or a lamp with a tight shade, hot air can affect the sensitive electronics. Look for a bulb rated for enclosed fixtures.

• Was the bulb compatible with the use? Not all bulbs are rated for outdoor use, or use with a dimmer or photocell.

If the burned-out bulb was a CFL, be sure to dispose of it properly. Some communities have hazardous-waste collection programs. The Idaho Department of Environmental Quality (IDEQ) has a recycling directory to help you find programs in your area. You can find it online at deq.idaho.gov/recycling. In Oregon, call your trash collector, city public works department or county landfill. Some retailers offer light bulb recycling as well.

My Bulb Burned Out!

Did You Know?Light fixtures are rated for use with incandescent bulbs. Since CFLs and LEDs use just a fraction of the electricity, you won’t exceed the safety threshold even if you choose a bulb with higher lumens.

Attic insulation reduces air flow around ceiling fixtures, like some recessed cans. This can create a fire hazard or cause bulbs to burn out early. Be sure these fixtures are installed correctly and are Insulated Contact (IC) rated.

Safety Tip

1. Replace old light bulbs with more efficient CFL or LED bulbs. In many cases, you will save more money in one year than what you spent on the new bulbs. This can translate to a one-year return on investment (ROI) of over 100 percent. Plus, savings will continue over the life of the bulb (25+ years for some). Is your savings account earning you this much?

2. Seal air leaks. Reduce drafts and keep bugs out by sealing leaks with caulk, spray foam or weatherstripping — a cheap fix that can have a big impact.

3. Set or program your thermostat. The U.S. Department of Energy suggests setting your thermo- stat to 68° in the winter and even lower while you’re asleep or away. If you have a heat pump, limit overnight reductions to 2 to 3 degrees.

4. Add insulation to your attic. This is usually the easiest and best place to add insulation. New homes in most of Idaho require an R-value of at least R-38. A contractor will check your insulation level and give you a bid for free.

INCREASED VALUE

MORE COMFORT+=

Current building code specifies 50 percent of bulbs installed in new homes in Idaho, and 75 percent in Oregon, must be CFLs or LEDs.

To invest in your home’s efficiency and make you more comfortable this winter, we suggest making five changes. Here are our top five suggestions:

When you take control of your energy use and invest in your home’s efficiency, you can increase its value, reduce monthly energy use and have a more comfortable home to live in.

5. Seal ducts. If your ducts are not sealed well, you may be paying to heat your attic or crawl space. A contractor can check your ducts and run an air leakage test.
