Nebraska Public Power District (NPPD) is committed to working in partnership with local utility customers to maximize the value of their energy purchases in a cost-effective manner. To understand its importance in our future, we need to examine where energy efficiency began.

As intelligence evolved, energy efficiency included finding easier ways to get work done. For example, the invention of the wheel was an early advance in energy efficiency. Fire is the oldest major source of energy controlled by humans. Its earliest uses began with and grew from cooking to heating of dwellings, clearing land, baking pottery and casting metal. Controlled fires required a considerable amount of effort for gathering fuel, so efficiency arose in the use of fuel.

Around the start of the 18th century, fire powered the first steam engine. Its development was revolutionary since, for the first time, fire could produce mechanical work. It also gave rise to searching for ways to achieve higher efficiency. This scientific discipline eventually evolved into what we now call mechanical engineering.

Only a few decades later, practical use of electrical power emerged, and by the end of the 19th century, humans began to produce more and more electricity to power incandescent lights and motors. Shortly thereafter, the invention of innumerable small machines and labor-saving devices made electricity a ubiquitous commodity. By the beginning of the 20th century, energy consumption per capita was accelerating.

The 1973 "energy crisis" brought the realization that energy sources might not keep pace with mankind's ability to use energy. Energy efficiency as we know it today began and was called “conservation” with the concept of “Just Use Less.” Congress established the Department of Energy in 1977 to diversify energy resources and promote conservation. The electric industry began to see efficiency as an energy resource whose avoided cost is less than building another power plant or procuring in the wholesale market to meet customer demand.

Efficiency programs began to yield market impacts beyond cost-effective energy savings. On March 15, 1992, the U.S. Environmental Protection Agency launched the ENERGY STAR® brand to help customers recognize high efficiency options. Around the same time, performance contracting began to provide access to needed capital and services for building energy performance improvements.

Recognizing that efficiency provided benefits beyond just saving energy, utilities began ramping up programs shortly after the start of the current millennium. Non-energy benefits such as managing electrical demand, increasing electric grid resilience and reliability, creating jobs, advancing technology and reducing greenhouse gas emissions became apparent.

Electrification is also a form of energy efficiency. As cited in Forbes, on Nov. 9, 2023, “Transitioning from a fossil energy system to a fully electrified one could cut up to 40% of final energy consumption. In buildings, for example, Artificial intelligence-driven technologies can save up to 20% in a building’s energy costs by combining building, weather, and user data to predict heating and ventilation demand. Load-shifting can also be automated to cool supermarket freezers down to a much lower temperature than required outside the peak demand hours. When peak demand periods occur, refrigeration is switched off and the freezers effectively operate like a battery storing energy.” In homes, air-conditioning systems can be operated in a similar way to provide energy demand reductions during peak periods while still maintaining indoor comfort.

Going forward, efficiency will be increasingly recognized for its financial and strategic value. There is a renewed focus on getting the most economic value from each unit of energy. Renewable generation will continue to grow, as well as energy storage, demand management and re-using waste heat.

For years, Southwest Public Power District, in partnership with Nebraska Public Power District, has been dedicated to safely generating and delivering reliable, low-cost, sustainable energy and related services, while providing outstanding customer service.

Now that April showers have passed, it’s a good time to check your home’s electrical system. The ground fault circuit interrupters—or GFCIs—that prevent electrocution could be damaged by power surges during storms. A GFCI, which can be part of an electrical receptacle or circuit breaker, trips the circuit when it detects ground faults or leaky currents. It protects the user of electrical equipment from electrocution by shutting off the electric path to that appliance. Nearly 50 percent of the 400 electrocutions that occur each year could be prevented by using GFCIs, according to the Electrical Safety Foundation International. Even when homes do have GFCIs, the foundation says, most homeowners don’t know how often to test them. You should test yours every month, and again after power surges, to check for damage. Here’s how to test your GFCIs: Push the “reset” button on the GFCI receptacle to prepare the unit for testing. Plug a lamp into the GFCI and turn it on. The lamp’s bulb should light up. Push the GFCI’s “test” button. The lamp should turn itself off. Push the “reset” button again. The lamp should turn on again. If the lamp doesn’t turn itself off when you push the “test” button, that means your GFCI is on the fritz. To fix it, call a licensed electrician.

When water gets into your laundry room—whether it’s from a broken washing machine hose or a late spring storm—your best bet is to treat it like an electrical emergency. If you know a storm is coming, it’s a good idea to unplug your washing machine, dryer and other major appliances. If a lightning strike causes a power surge, your appliances could get damaged or even ruined. If you haven’t unplugged your appliances and stormwater gets indoors, minimize your risk of electrocution by waiting for the water to recede and then shutting off the power supply. Do not do this while standing in water. Do not touch your power cords during a surge or if your appliances are sitting in water. Also, shut off the hot and cold-water supply lines. Don’t touch anything until you do that; as you know, water and electricity absolutely do not mix. Next, call an appliance repair professional, an electrician or a plumber to assess the damage to your washer and dryer. Don’t turn on your washer and dryer after they get wet, even if they have air-dried. According to Consumer Reports, turning on appliances too soon could shock or electrocute you if their interior components are still wet. It can also ruin your appliances.

It doesn’t make sense to put an air conditioning system in a garage because the cool air will leak right through the door, ceiling and walls. But you can keep the space a bit more comfortable this summer by adding insulation. Insulated walls, ceilings and doors can block the heat so it doesn’t penetrate to the inside of the garage, and they can keep the cool, conditioned air indoors where it belongs. In the winter, it can help keep the cold air out. If you need a new garage door, choose an energy-efficient model, which can reduce energy loss through the garage door by up to 71 percent, according to manufacturer Clopay.

If the air inside your house is dusty, it might mean your air conditioning ducts have sprung leaks. If you’re changing your air conditioner filter regularly, it will trap dust and pollutants that get into the indoor air so they never make their way into the duct system—or back into the air. But if the ducts have tiny holes or cracks or joints that aren’t well-sealed, dust can bypass the filter and sneak directly into the ducts. Once dust gets in there, the duct system will blow it all over the house. Dust in the ducts and in the air can raise the temperature in your home and force your air conditioning system to operate inefficiently and struggle to keep your home cool during the summer. It's well worth it to have the ducts of your air conditioning system sealed at the joints. Not only will it prevent dust from flying around your house, it could reduce your air conditioning bills this summer. The average house loses about 20 percent of its conditioned air through ducts that are improperly installed or are leaking at the joints.

A springtime tune-up can prevent your air conditioning system from going on the fritz later, when the weather is so hot that you won’t want to be without the a/c for even a few hours. It typically costs less than $150 to have a professional inspection of your system, and it’s well worth the money. Some contractors offer an annual preventive maintenance agreement, which will cost a few hundred dollars a year and typically includes a fall and spring inspection of your HVAC system and discounts on repairs and equipment. A better deal most often is to pay as you go for individual inspections. Either way, your cooling system will get attention from a qualified, licensed service technician who is trained to spot problems that most homeowners overlook. The tech might even alert you if a small repair now will prevent your family from sweltering this summer during an a/c breakdown.

Nothing spoils a fun day of Easter egg hunting like an accident involving electricity. Here are eight tips for hiding eggs safely: · If you’re hiding some of the eggs indoors, steer clear of electrical outlets, plugs, light sockets and extension cords. · Outdoors, avoid placing eggs near air conditioning units, low-hanging overhead wires or in trees near electric lines. · Pick up anything on the ground that the children could trip on. They’ll be focusing on finding eggs, not their footing. · Same goes for holes and uneven patches of ground in your yard. · Place eggs well within the boundaries of your lawn. Don’t put them close to the street or driveways. · Bushes are great hiding places for eggs—and also for bees, snakes and other critters that you won’t want your children near. · Avoid bushes that are thorny or have recently been sprayed with pesticides. · Hide your eggs no more than two hours before the hunt so they don’t spoil.

Spring is a great time to save energy at home when most days are neither cold nor hot, so you don’t need to turn on either the heat or air conditioning. Take advantage of the nice weather to use less energy now and prepare your home to be more efficient this summer. Some tips: 1. Open the windows—all of them—to create a cross-breeze all over the house. This keeps the home cool without air conditioning. 2. Call an HVAC service tech to inspect your air conditioning system. A springtime check will give you a chance to repair any problems before the weather gets hot and a poorly maintained system leaves you without cool indoor air. 3. Switch your ceiling fan blades so they rotate counterclockwise. This will create a downward breeze, which will keep anyone in the room comfortable. 4. Use a caulk gun to seal cracks and openings on the indoor side of exterior walls—like around cable and phone lines and electrical outlets. 5. If you don’t have a programmable thermostat, now is a great time to install one. This device can save you 5% to 15% on heating and cooling bills, according to the U.S. Department of Energy, because it adjusts the temperature for times when the family is sleeping or away from the house.

By: NPPD Energy Efficiency Program Manager Cory Fuehrer First introduced in the 1950s, recessed lighting or “can lighting” is still a popular choice for residential and commercial lighting. Traditionally, these fixtures consist of a cylindrical or square-shaped metal housing that extends above the ceiling so only the trim or baffle is visible on the ceiling surface. A lamp or bulb is screwed into a socket mounted inside the top of the housing. When switched on, the fixture provides a streamlined and unobtrusive appearance that complements various interior design styles. Despite these benefits, recessed can lights have a reputation for being inefficient. Though they can be fitted with an energy-efficient LED bulb, many still use less-efficient incandescent bulbs. Recessed fixtures with housing that is not sealed can also lose costly heated or cooled air from the space below. According to the U.S. Department of Energy, these energy losses can account for up to 50% of a ceiling’s total thermal loss. Though customers can install a more expensive, sealed can light or retrofit existing fixtures with seals, they now have another choice: canless recessed lights. Canless recessed lighting refers to a type of fixture installed directly into the ceiling. They do not have a recessed can or housing that extends above. Moreover, canless recessed lights are self-contained units that integrate the housing, trim, and light source into a single fixture. They are an ideal option for existing homes and facilities as they do not require any large holes in the ceiling and can be easily retrofitted to existing can lights. Compared to traditional recessed lights, canless recessed lights are generally more compact, allowing for quick and easy installation. This makes them suitable for installations in areas with limited space between the ceiling and other structures, like ductwork or pipes. They also have better energy efficiency since they eliminate the need for separate housing that is prone to air leakage and heat loss while utilizing solid-state LED lighting technology which produces the most amount of light per watt of electricity. Since LEDs produce very little heat compared to other bulb options, customers also save on cooling costs. Much like their predecessors, canless recessed lights offer multiple trim options, like baffle, pinhole or eyeball trim, to suit different design preferences. Perhaps the best surprise customers find is that canless fixtures typically cost 25% to 50% less when compared to their canned cousins. Like many other high-performing lighting products, manufacturers can submit their canless recessed fixture products for ENERGY STAR® recognition. Those displaying the ENERGY STAR® label on their packaging are the easiest way customers can assure they are selecting a quality, energy-efficient light. In partnership with Nebraska Public Power District, Southwest Public Power District wants to help their customers gain the most benefit from the electricity they provide.
