May 2022 EnergyWiseSM Tip: Under Pressure

By: NPPD Energy Efficiency Program Manager Cory Fuehrer Have you heard what the latest gossip around the water cooler is about? The water cooler, itself! Business experts have long debated whether there is value to the chat that occurs when office employees meet during their venture to the device to obtain hot water for tea, coffee or a refreshing glass of cold water. Water cooler conversations tend to revolve around weekend plans, popular TV shows, movies, sports, or office-related, non-work-specific news. While traditional management approaches ranged from discouraging to prohibiting these interactions, research from the University of California, Santa Cruz reveals these interactions are crucial for boosting company culture, improving employee collaboration, fostering social support, and reducing stress. So where did this common office fixture come from? In 1906, Halsey Willard Taylor and Luther Haws were exploring ways to further reduce the deadly impact of typhoid in schoolchildren. Research during the middle of the previous century determined it primarily spread though drinking contaminated water. Observing that schoolchildren were drinking from communal tin cups of water, Hawley invented and placed the water fountains (or bubblers) into schools. In 1909, Haws created the Haws Sanitary Drinking Faucet company and patented his water cooler in 1911. The early water coolers stored water in a sealed glass container and used large blocks of ice to chill it. Shortly before the 1920s, the first five gallon water bottles began to appear and the iconic “upside-down bottle on a cooler” design often associated with 20th-century office life was launched. By 1938, the world’s first ‘self-contained electric water cooler’ was patented that provided internal refrigeration and eliminated the need for ice deliveries. The 1950s and ‘60s saw the introduction of hot and cold-water dispensers, which remain the standard design today. Today’s water coolers also have features such as touchless dispensing sensors, temperature controls, UV sterilization and machine usage tracking. Since sustainability and optimizing employee health have become major business interests with concerns of plastic waste skyrocketing and microplastics entering our bodies, most businesses have or are switching to plumbed and internally filtered water coolers. While these features can significantly add to the unit’s energy use, water coolers that have earned an Energy Star® certification save 22% or more of the energy that an uncertified, conventional model would use. In fact, if all water coolers sold in the U.S. were Energy Star®-certified, the energy cost savings would equate to more than $250 million each year. With the average commercial water cooler typically lasting five to 10 years, total savings would be between $1.25 and $2.5 billion. Your local public power provider, in partnership with Nebraska Public Power District, has additional ideas of how to efficiently use the electricity they provide. In addition, they may offer EnergyWiseSM incentives to reduce the initial costs of efficiency improvements. Contact your local utility or visit www.energywisenebraska.com for additional details.

Laundry can be a bigger winter energy user than people expect, but small adjustments save money without sacrificing cleanliness. Some rules of thumb: · Modern detergents work well in cold water, and many loads come out just as clean. · Wash full loads and select the right water level. For lightly soiled items, choose a quick or eco cycle. · Use high-spin settings to remove more water and shorten drying time. Dryer balls help separate clothing so warm air circulates better. · Clean the lint trap every cycle and check the vent hose for buildup. A clogged vent extends dryer run time and raises fire risk. · Time laundry for mid-day when the home may already be warmer or when off-peak electricity rates apply.

An electrical outlet that’s slightly warm to the touch is not uncommon during heavy use, but it can also be a sign of danger. · Start by unplugging any devices that are using it, and then feel the outlet again. If the warmth disappears, the problem may be the appliance or a loose plug. Test the device on another outlet. · If the outlet remains warm with nothing plugged in, do not use it. That suggests loose wiring, a failing receptacle or an overloaded circuit. Call an electrician to diagnose the trouble. · Never use extension cords or ungrounded adapters as a long-term fix. Limit high-draw appliances to dedicated circuits and never run space heaters from a power strip. · If you see discoloration, smell burning or notice sparks, shut off power to the circuit and call a licensed electrician.

Even if you had a tech come to your home for a pre-season heating check, you should keep on top of simple HVAC maintenance to up your chances of making it through the winter without any emergency repairs. Cold snaps in February put heavy demand on heating systems, and small issues can quickly become big emergencies. Following a brief maintenance checklist can save money and prevent expensive, late-night calls.  · Begin with filters. Replace disposable filters or clean reusable ones. A clean filter reduces strain and improves airflow. · Check vents and registers to make sure furniture or curtains aren’t blocking airflow. Restricted airflow makes the system run longer and increases wear. · Inspect visible ductwork where you can access it. Seal loose connections with foil HVAC tape or mastic. Leaky ducts waste heated air and force the furnace to run more to maintain temperature. · Clear any snow or ice from outdoor heat-pump units and keep a three-foot clearance around them. Unusual noises or persistent burning smells are early signs of trouble. Call a licensed HVAC technician before a minor issue becomes a failure.

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.

This Valentine’s season, show your appliances a little love and they’ll return the favor in lower bills and fewer surprises. Start with the refrigerator: Vacuum the coils every six months, check door gaskets for tight seals, set the fridge at 37 to 40 degrees, and then lower the freezer to 0 degrees. This will help the appliance run more efficiently and use less power. Next, turn your attention to your clothes dryer. Clean the lint trap after every load and inspect the vent and duct for buildup; restricted airflow makes dryers run longer and raises fire risk. Consider having a technician clean the exhaust duct annually. Don’t forget the water heater. Lowering the thermostat to 120 degrees and flushing a few gallons annually to remove sediment improves efficiency and extends life. Your heating system has been keeping you warm all winter; give it some TLC by replacing HVAC filters regularly. A clogged filter forces the system to work harder. Finally, make some small fixes; they add up. Tighten loose electrical connections, replace cracked power cords and run a quick check for unusual noises or smells. These are easy tasks that prevent breakdowns and save energy. They can also keep your home safe and comfortable. Think of it as home self-care that pays dividends.

By: NPPD Energy Efficiency Program Manager Cory Fuehrer Is this the winter you finally have had enough of shoveling now? Data analyzed by the Center for Injury Research and Policy found that annually, snow shoveling leads to about 100 deaths and 11,500 emergency room visits in the U.S. Of those treated for injuries, about 15% resulted from the shovel itself. Maybe it’s time to consider an electric snowblower? Cordless, battery-electric blowers can clear paths up to 24 inches wide through as much as 20 inches of snow. Unlike their gas-powered counterparts, they require very little maintenance, run relatively quietly, are usually lighter and start with just a push of a button. When it comes to one of the quickest, least labor-intensive ways to dig out after a big snowstorm, they are hard to beat. Also, consider the following additional advantages: Single-Stage and Two-Stage Electric snowblowers are available in both single-stage and two-stage models. Single-stage units are lighter and easy to maneuver. They use a single auger to both scoop and discharge snow and are best suited for light to moderate snowfalls. Two-stage snowblowers have an additional impeller, which helps throw the snow further while handling heavier snow more effectively. Power Source Unlike their underpowered, corded predecessors, most electric snowblowers today run off rechargeable batteries for about 30 to 45 minutes on a single charge, which is about how long a tank of gasoline powers a gas snowblower. Operating time can be extended with multiple batteries. Compact and Easy to Store Electric snowblowers take up significantly less space, making them ideal for garages with limited storage space. Maintenance Unlike gas-powered units that require oil changes, tune-ups and gasoline stabilization or draining for extended periods of storage, electric units require almost no maintenance. To keep an electric snowblower running season after season, simply store the charger and batteries indoors when they aren’t being charged or used. Since batteries do not hold the same amount of charge when the temperature drops below freezing, storing and charging them indoors ensures the greatest run time. Both electric and gas snowblowers last around 10 years with proper care and maintenance. However, electric snowblowers require much less effort to maintain. Cost Gasoline-powered snowblowers usually have a higher purchase price, as well as fuel and maintenance costs when compared to electric snowblowers. This is especially true when evaluating smaller or single-stage units.  Your local public power provider, in partnership with Nebraska Public Power District, also offers EnergyWiseSM incentives to their customers who purchase an electric snowblower.
