March 2022 EnergyWiseSM Tip: Smart Thermostats

The days are getting longer, and that means you don’t need your home’s outdoor lights to automatically turn on quite as early. Take a few minutes this weekend to reset outdoor motion sensors and timers to avoid wasting electricity when natural daylight is available. Walk around your property and adjust timers to match sunrise and sunset schedules. Photocell sensors should trigger lights only when it’s actually dark. Motion-activated floodlights should be properly aimed to illuminate paths without lighting empty spaces. While you’re at it, replace any old bulbs with LED alternatives, which can reduce energy use. Consider smart lighting controls that allow scheduling from your phone or tablet.

The month or two between cold and warm weather gives you the perfect opportunity to save energy. Milder temperatures mean heating season is winding down, but it’s not warm enough for air conditioning. Some call this a “shoulder season.” Take advantage of the moderate weather by keeping both the heat and the air conditioning turned off. Instead, open windows to draw in fresh air and turn on ceiling fans. Inspect and seal air leaks and clean AC filters. Open blinds, curtains and shades during daylight hours to reduce the need for electric lighting. The shoulder season is brief, so forming smart habits now can keep energy bills lower while the outdoor weather keeps your home naturally comfortable.

April is a great time to plant a tree. Arbor Day is April 24 this year, and people all over the world will plant trees in their yards and communities. The day is a reminder that spring is the season to think long term about your home’s energy use. Planting trees, shrubs or climbing vines now can provide natural cooling in the summer and save energy on air conditioning. Deciduous trees—the ones that shed their leaves in the fall—are particularly effective for energy efficiency because their lush leaves shade your home and yard in the summer and then allow sunlight to shine through your windows in the winter after their leaves fall. Position trees on the south and west sides of your house to block harsh afternoon sun. Fast-growing trees, like maples or lindens, offer benefits within a few years, while slower-growing species add long-term value and curb appeal. Shrubs and vines can shade walls and windows while enhancing landscaping. A trellis with vines near sunny windows can reduce heat gain, lowering cooling costs. Beyond energy savings, planting trees improves air quality, supports wildlife and adds value to your property. When selecting plants, consider native species that require minimal water and maintenance. By planting shade this spring, you’ll enjoy cooler indoor temperatures, and you could lower your heating and cooling bills.

Spring rain is good for flowers. It is not good for extension cords. Water and electricity, as you know, are a risky mix. April is a smart time to check your outdoor setup before yard work and storm season begin. • Start with your cords. If a cord is cracked, frayed or warm when in use, replace it. Do not tape it. Do not run it through puddles. Keep connections off the ground and out of wet grass. • Plug outdoor tools only into outlets protected by a ground fault circuit interrupter, or GFCI. These are designed to shut off power fast if something goes wrong. Test them each month. Push the “test” button. Then reset. • Using power tools in a damp garage or driveway? Dry your hands. Wear shoes. Keep cords away from metal and standing water. • Never pull a plug by the cord. Grab the plug itself. Yanking the cord can loosen wires and create a shock hazard later. • Store cords indoors when you’re finished using them outdoors. Sun and rain break them down over time. • If you use a generator during storms, keep it outside and far from doors or windows. Never plug it directly into a wall outlet. Small steps matter. A quick check now can prevent injuries later.

Lightning, high winds and torrential downpours can put your home and neighborhood at risk of power surges and outages. And those can damage your expensive household electronics. So, prepare for spring storms to protect yourself and your electronics from harm. · First, install surge protectors as a first line of defense. Use them for computers, televisions, exercise equipment and other sensitive devices. Look for protectors with indicator lights that show when protection is active. · During severe storms, unplug electronics and turn them off—excluding things like the refrigerator and medical oxygen tanks. Even the best surge protectors cannot block a direct lightning strike. · If your home experiences frequent outages, consider installing whole-house surge protection, which is installed at the electrical panel. An electrician can explain whether this option makes sense. · Backup power options, such as battery packs or portable generators, can help keep essential devices running in case the power goes out. Portable generators should only be used outdoors and far from windows and doors to prevent carbon monoxide poisoning. · After an outage, wait a few minutes before turning electronics back on. This helps protect devices from voltage spikes as power is restored.

As you get to the business of spring cleaning, inspect your tools—vacuum cleaners, pressure washers, carpet cleaners and power tools—to make sure they are in shape for another season. · Before starting any project, inspect cords and plugs for cracks, fraying or exposed wires. Damaged equipment should be repaired or replaced. Using tools with ground-fault circuit interrupter protection is especially important in garages, basements and outdoors. · Follow manufacturer instructions and avoid overloading outlets or power strips. High-powered tools should be plugged directly into a wall outlet, not extension cords, unless the cord is rated for the tool’s electrical load. · When cleaning or repairing appliances, unplug them first. Water and electricity are a dangerous combination, so keep tools dry and avoid using them with wet hands or on damp surfaces. · For outdoor projects, use extension cords labeled for outdoor use and keep connections off the ground. Wear appropriate protective gear, including gloves and eye protection, and keep tools away from children and pets. Taking a few extra minutes to check equipment and follow basic precautions can prevent injuries and electrical hazards while tackling spring projects.

By: Energy Efficiency Program NPPD Manager Cory Fuehrer Have you ever gone over to a friend’s place for a fish dinner and left smelling like fried carp? If so, it could be that their kitchen exhaust hood was not working properly. While commercial kitchens use exhaust systems that are fairly complex, exhaust hoods in most homes are relatively simple. They capture polluted air by drawing it in with a single fan and venting it outside or filtering it before recirculating the air back into the kitchen. In doing so, they reduce the amount of airborne grease, smoke and odors to help protect your walls cabinetry and ceilings. Many kitchen exhaust hoods even assist in removing excess heat or providing additional light over a cooktop or range. Whether you are building a new home, remodeling a kitchen, replacing an old hood or are simply wanting to make the most of your current one, the following factors impact a hood’s effectiveness and efficiency while clearing the air: Types Under-cabinet – Most common type. The fan is usually located in cabinetry above. Wall-mount/Chimney – In addition to the hood, the ducting and often the fan housing are visible. Often matched with high-performance options. Island/Canopy – Ducting extends down from the ceiling over a cooktop. The fan is in the ducting or mounted outside the home. This type requires higher fan capacity due to lack of a wall for smoke containment. Downdraft – Unit is built-in behind or next to the cooktop. This type also requires higher fan capacity due to fumes being drawn downward. Built into microwave – With an overhead microwave, this type is a popular space saver. However, fan capacity is limited. Ducted, Ductless and Convertible Ducted range hoods vent externally, which means they draw kitchen air out of the house through ductwork in the wall, ceiling or floor. External venting is available in all types of range hoods but is particularly common in wall-mount, island, canopy and downdraft types. Ducted range hoods are often labeled as “vented” in product names and specifications. If reducing heat in the kitchen or removing odors is a significant concern, a ducted range hood is recommended. Ductless range hoods filter kitchen air then recirculates it back into the kitchen. Under-cabinet and microwave hoods are most commonly ductless. Ductless range hoods are most common in the under-cabinet and built-in microwave styles. Product specifications will most likely say “recirculation”, indicating it is ductless. As the name implies, a convertible range hood can vent externally or recirculate the kitchen air. Under-cabinet and canopy hoods are the most likely types to be convertible, but keep in mind that kits are available for non-convertible models that make them convertible. Rated CFM The Cubic Feet per Minute (CFM or cfm) rating is a measurement of fan capacity. Hoods over electric ranges or cooktops should have a minimum capacity of 100 CFM per linear foot of appliance. Fan capacity for gas appliances should be a minimum of 1 CFM per 100 British Thermal Units (BTUs) that the stove or cooktop is rated at. (e.g., a 40,000 BTU stove needs 400+ CFM). Note that residential building codes in the state of Nebraska require installation of a makeup air units for kitchen exhaust systems capable of moving 400 CFM or more. Width and Mounting Height The hood must be at least as wide as the stove or cooktop beneath it, if not six inches wider. A 30-inch stove should ideally have a 36-inch hood to capture peripheral smoke and grease, especially for island or canopy installations. For optimal performance, hoods should be mounted 20 to 24 inches above electric ranges and 24 to 30 inches above gas ranges.

Spring is a good time to give your home’s electrical system a basic safety check before heavier summer use begins. Start by testing smoke detectors and carbon monoxide alarms and replacing batteries if needed. Check outlets and switches for warmth, buzzing sounds or discoloration, which can indicate wiring problems. Inspect power strips and extension cords and replace any that are damaged or overloaded. Power strips should never be daisy-chained together. Make sure cords are not pinched under furniture or stretched across walkways where they can be damaged. In kitchens and bathrooms, confirm that outlets near sinks are protected by ground-fault circuit interrupters. These outlets help prevent shocks and should be tested monthly. Spring is also a good time to clear clutter away from electrical panels and make sure breakers are clearly labeled. Never block access to the panel. If you notice flickering lights, frequently tripped breakers or burning smells, contact a qualified electrician. Addressing small issues early can prevent fires and costly repairs later.
