November 2024 EnergyWiseSM Tip: Night Lights

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.

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.
