January 2026 EnergyWiseSM Tip: Insulation

January 14, 2026

By: NPPD Energy Efficiency Program Manager Cory Fuehrer

Everyone’s looking for a good deal. There’s no exception when it comes to home improvements, 

especially if you own an older home. If you find yourself in that category and are planning a 

major renovation, consider that adding insulation during your project often pays for the 

additional cost with energy savings in two to five years. According to Energy Star®, homeowners 

can save an average of 15% on heating and cooling costs by adding insulation in attics, floors 

over crawl spaces, and accessible basement rim joists.


Adding insulation can also increase the value of your home. Remodeler Magazine’s “Cost vs. 

Value Report,” which breaks down both the cost and return on investment of many home 

improvement options, noted that adding fiberglass attic insulation increased home value by an 

average of 17%. Considering the North American Insulation Manufacturers Association 

estimates that almost 90% of existing U.S. homes are under-insulated, familiarizing yourself 

with the following most-common types might be a good place to start.


Blanket Insulation

While most commonly sold in rolls or batts of spun fiberglass filaments, 

blanket insulation is also produced from cotton, cellulose and mineral wool. 

They’re made in various thicknesses, but usually in the standard widths of 15 

and 23 inches so they easily fill the cavities between joists or studs. Blanket 

insulation is also ideal for unfinished attics. Not only is it easy to cut and 

install, but more than one layer can be installed to achieve the desired level of insulation.


Loose-Fill and Blown-In Insulation

Since attics often have limited headroom and numerous obstructions, loosefill insulation is a popular choice. It can easily be blown on top of existing

insulation and other obstructions like ducting, can light fixtures and cross 

beams. Rock wool, cellulose and fiberglass are the most common materials 

used to make loose-fill insulation.


Foam Board or Rigid Foam

Foam board is a rigid panel made from polystyrene or polyisocyanurate. It 

provides a high level of thermal resistance (R-value) per inch when 

compared to other types of insulation. It can easily be installed in a variety of 

applications, including walls, roofs and floors. Because it provides a vapor 

barrier when properly sealed, it can help control moisture, reduce air leaks

and keep pests from invading your home. Because of its rigidity, it's self-supporting, doesn't sag 

and provides continuous insulation, which effectively blocks heat transfer better than batts.


Spray Foam and Foamed-In-Place Insulation

Similar to foam board, spray foam insulation and foamed-in-place insulation

is a liquid polyurethane plastic that is sprayed directly on the area being 

insulated. As the liquid is sprayed, it expands and hardens to create a dense

foam that seals gaps and forms an air-tight vapor barrier. This significantly 

improves energy efficiency since it significantly reduces heat transfer while 

stopping air leaks in walls, attics and crawlspaces at the same time. There are two main types of 

spray foam insulation: open-cell, which is less dense and good for soundproofing; and closed cell, which is denser, offers higher R-values, adds structural strength and resists moisture.


Adding insulation can be one of the most cost-effective projects you can do to make your home 

energy efficient. If you primarily use electricity to heat your home and there are six inches or less 

of insulation in your attic, your local public power provider may have an EnergyWiseSM

incentive available once installation is complete. Contact your local utility or visit 

www.energywisenebraska.com for additional details. Your local utility, in partnership with 

Nebraska Public Power District, wants to help you get the most value from the energy needed to 

keep your home comfortably warm.

If you have your expensive electronic devices plugged into surge protectors, good for you! But if you bought surge protectors, plugged everything into them and forgot all about them, you could be overlooking a potential problem: Old surge protectors wear out and need replacing every now and then. Surge protectors do not last forever. The components that absorb electrical surges can wear out over time. After enough surges, a device may continue working as a power strip while providing little or no surge protection.. Check your surge protector occasionally. Many models have an indicator light that shows whether surge protection is still active. If the light is off, consult the manufacturer's instructions. It may be time for a replacement. Inspect the device’s cord and outlets. Replace the unit if you see scorch marks, cracks, frayed wires or other damage. A power strip that feels unusually warm should also be replaced. Experts often recommend replacing surge protectors every few years, especially in areas that experience frequent storms and power fluctuations.  A quick inspection takes only a minute. A stereo system or piece of home theater equipment that gets fried during a power surge ruins that investment forever.

Ceiling fans can make a room feel cooler. But they do not actually lower the temperature in that space. According to the U.S. Department of Energy, fans create a wind-chill effect that helps people feel cooler. The room itself does not become cooler. In fact, DOE says, ceiling fans may allow homeowners to raise the thermostat setting by about 4 degrees in the summer without reducing comfort. That means a fan saves energy only when people are there to enjoy the breeze. Running a ceiling fan in an empty room does not improve comfort and uses electricity unnecessarily. Also, did you know that you need to change the direction that your fan blades spin every spring and fall?  During summer, ceiling fans should rotate counterclockwise. That pushes air downward and creates the cooling effect people feel. Running them in the wrong direction for the season won’t keep you comfortable.

When an electric bill suddenly rises, many people assume their electric cooperative raised its rates. Sometimes that’s the case. But more often, the biggest reason is simple: You used more electricity. According to the U.S. Energy Information Administration, nearly 90% of U.S. households use air conditioning. During hot weather, cooling systems run longer and more often. Even if the price of electricity stays the same, using more electricity means a higher bill. Heat waves can have a bigger effect than you might realize. A few extra days of very hot weather may cause an air conditioner to run for hours longer each day. Refrigerators, freezers and dehumidifiers may also work harder during extreme heat. If your bill seems unusually high, compare your electricity use with the same month last year. Most utility bills show the number of kilowatt-hours used. That number can tell you whether the increase came from higher use, higher rates or a combination of both. You can also look for simple causes if you notice an unexpected jump in your energy use. A clogged air filter, a thermostat set a few degrees lower than usual or windows receiving direct afternoon sun can all increase cooling costs.  The next time your electric bill arrives, don't just look at the amount due. Check how much electricity you used. The answer to a higher bill is often hiding in that number.

By: NPPD's Energy Efficiency Program Manager Cory Fuehrer According to Consumer Reports , 2018 was the first automotive production year when more new models were equipped with light-emitting diode (LED) headlights than halogen or high-intensity discharge (HID) headlights. Today, all new electric and hybrid vehicles are equipped with LEDS, as are most internal combustion engine vehicles. However, in June of 2026, of the 297.5 million registered vehicles in the United States, more than two-thirds were manufactured before 2018. If you drive one of these earlier-model cars, you are likely to be using the older lighting technologies to see your way down the road at night. Should you upgrade your headlights? Consider these points: Brighter illumination The number of lumens a light produces is a measurement of the total perceived light emitted by a source. As an example, a standard 100-watt incandescent lightbulb produces about 1,600 lumens. LED headlights produce 3,000 to 12,000 lumens to provide impressive lighting ranges that can reach beyond 300 yards. In comparison, halogen or HID headlights only produce 1,000 to 1,500 lumens and have a shorter lighting range that only reaches up to 150 yards. Energy Efficiency Depending on which headlights are being compared, LEDs are four to ten times more efficient than halogen or HID headlights in converting electricity to light. This is one of the main reasons LEDs can produce so many more lumens on an automobile’s headlamp circuit than the older technologies. Better visual acuity and safety When describing “white” light, the term “Kelvin” (using the symbol “K”) is used to describe how “warm” or “cool” the color is; the lower the Kelvin level, the warmer and more yellowish the light is. Traditional halogen and HID headlights produce light around 3200K. LED headlights produce crisp, directional white light around 5000K to 6500K, which improves contrast and distance visibility to the human eye. Less eye fatigue Studies have shown that the sharper contrast described above allows drivers to spot road signs, lane markings and obstacles much earlier, thus reducing cognitive and visual load during extended nighttime trips. Longer lifespan and lower overall cost Drivers using halogen or HID headlights typically get about 1,000 to 2,000 hours of use before they replace them again at an average cost of $20 to $60 per pair. Even though LED headlights cost three to five times more at an average cost of $50 to $175 per pair, they will last 30,000 to 50,000 hours and save money and time through fewer future replacements.

That includes helping you safely and comfortably travel from point A to point B at night.

Smart thermostats promise to help homeowners save energy while keeping their homes comfortable. But are they worth the investment? The short answer: They’re worth it. Unlike traditional thermostats, smart models connect to home wi-fi and can be controlled through a smartphone app. Many also “learn” a household’s schedule and automatically adjust temperatures when people are asleep or away. When a smart thermostat lowers or raises the temperature for several hours a day, it can reduce heating and cooling costs. Because smart thermostats automate these adjustments, they can help households maintain energy-saving settings without anyone having to remember to change them manually. Some models also compile energy reports that show how often the system runs and offer suggestions for reducing energy use. However, smart thermostats may not be necessary for every home. If you live in an older home, you might need an electrician to install additional wiring to support yours. And smart units are pricier than basic programmable units. Plus, you need a stable internet connection for a smart model to operate consistently well. If you already have a programmable thermostat, a smart unit might not save you much additional money. And if you work at home all day and need to keep the heat or a/c at a comfortable setting, you won’t want a thermostat that automatically makes your home colder on winter days or warmer during summertime working hours.  Still, for homeowners who frequently forget to adjust the temperature or want the convenience of remote control, a smart thermostat can be a useful tool for improving comfort and managing energy use.

Summer heat can be tough on people. It can also be tough on batteries. Many of the devices we use every day contain lithium-ion batteries. That includes phones, laptops, tablets, power tools, e-bikes and e-scooters. These batteries work best when they stay within a moderate temperature range. Excessive heat can shorten battery life and, in rare cases, create safety risks. One of the worst places for a battery-powered device is a parked car. On a sunny day, temperatures inside a vehicle can climb quickly. Leaving a phone or laptop in a hot car can damage the battery and reduce its ability to hold a charge. Watch for warning signs. If a battery becomes unusually hot, starts swelling, leaks fluid or gives off a burning smell, stop using the device immediately. Damaged lithium-ion batteries can become dangerous. A few simple steps can help: • Keep devices out of direct sunlight. • Do not leave them in hot vehicles. • Use the charger recommended by the manufacturer. • If a battery-powered device becomes very hot while charging, unplug it and let it cool.  A little heat awareness can help your devices last longer and operate more safely.

By: NPPD's Energy Efficiency Program Manager Cory Fuehrer If you have traveled from Nebraska’s panhandle towards the southeast in the middle of summer, you likely know it can be a long and hot road trip. However, the further south and east you travel, you will probably notice that it is not only the temperature that is rising: humidity. High humidity can make those summer days feel even sweltering. While air-conditioning systems are tasked with removing most of this excess indoor humidity, many homes and businesses in the eastern half of the state also require stand-alone dehumidifiers to achieve acceptable levels. The Consumer Product Safety Commission and the U.S. Environmental Protection Agency recommend a humidity levels between 40 and 50% for most indoor environments. In addition to eliminating the muggy, clammy feeling, additional dehumidification can: Improve air quality Lessen allergy and asthma symptoms Inhibit mold growth Diminish musty odors Reduce airborne dust Suppress dust mites Protect a home or building’s structural integrity However, operating dehumidifiers can have a dramatic impact on summer utility bills. Even a medium-sized portable unit (50 pints per day) can add an additional $100 per month if the unit is set to operate continuously on its highest setting. If your home or business requires a separate dehumidifier to manage humidity level, here are some ideas of how to do it most efficiently. When shopping for a dehumidifier, purchase an ENERGY STAR®-certified model. Dehumidifiers that earn this certification use more efficient refrigeration coils, compressors and fans to remove the same amount of moisture as a similarly sized conventional unit but use about 15% less energy. Dehumidifier efficiency is measured with an Integrated Energy Factor (IEF), which is in the amount of electricity (kilowatt hours (kWh)) the unit consumes for each liter (L) of moisture removed from the air. To be eligible for certification, minimum IEF values are: Units rated up to 25 pints/day – IEF of =.70 L/kWh or greater. Units rated at 25.01 to 50 pints/day – IEF = 2.01 L/kWh or greater. Units at over 50 pints/day – IEF = 3.30 L/kWh or greater. Set the humidistat so the dehumidifier does not run continuously. For basements in the summertime, 50% relative humidity is recommended. In colder weather, relative humidity levels between 25 and 40% are advised to reduce condensation on windows. Tightly close all windows and doors to the area being conditioned to minimize humidity coming from outside air. Place the dehumidifier in the area with the highest humidity but avoid creating a safety hazard by placing it in or near water. Dehumidifiers are not the solution to standing water (or running water) in basements. Make sure the dehumidifier is connected to a properly grounded outlet. Position the dehumidifier away from the wall or furniture so air can freely circulate through the unit. Hook up a drain hose to the dehumidifier to eliminate the need to continuously empty the tank. Keep the dehumidifier clean. Wipe or vacuum dust and dirt from the coils and fan. If you have a choice of fan speeds, higher speeds are more efficient, though lower speeds are quieter. Reduce energy use during peak electric use periods. Put your dehumidifier on a timer to turn it on at 9 p.m. and off at 10 a.m. In partnership with Nebraska Public Power District, your local utility wants to help you stay cool, comfortable and healthy this summer.

During the summer, attic temperatures can climb far above outdoor levels, allowing heat to radiate down into living spaces. This hidden source of heat can make your air conditioning system work harder than necessary. Start by checking attic ventilation. Soffit and ridge vents should be clear and unobstructed to allow hot air to escape. Blocked vents can trap heat and increase indoor temperatures. Gaps around attic access points, such as pull-down stairs or hatches, can also allow hot air to enter the home. Sealing these areas with weatherstripping or insulation can help reduce heat transfer. In some cases, attic fans may improve airflow, but they should be used carefully to avoid disrupting the balance of the home’s ventilation system. Still, addressing attic heat does not require a full renovation. Even small improvements in insulation can make a difference by slowing the movement of heat into living areas.
