If you’re one of the more than 4,600 Nebraskans with an electric vehicle (EV) registered in Nebraska this year, congratulations! According to www.fueleconomy.gov, your vehicle converts more than 77% of the electrical energy from the grid to power at the wheels. Conventional vehicles only convert about 12% to 30% of the energy stored in gasoline and diesel-fueled vehicles only fare a little better, falling short of 40%. When you’re driving an EV, you’re driving the “top-of-class” for energy efficiency!

To garner even more efficiency, consider these practices for EV charging:

Do not fully charge the battery - To maximize battery life, daily charging should be to approximately 80% of battery capacity. For occasional use and long trips, charging to 100% is fine, but everyday charging to full capacity can lead to decreased battery life. Another issue with charging to 100% is the vehicle regenerative braking will not engage, meaning the EV is not running at maximum efficiency.

Avoid extreme heat while charging - If possible, avoid charging in extreme heat. Although battery packs are designed for extreme conditions, it is better to charge during the coolest times of day, so the battery thermal management system doesn’t get overworked.

Pre-heat during cold weather - For a fully electric vehicle (not a plug-in hybrid) the battery – rather than the hot gas engine – becomes the primary source of heat. When an EV’s heater is engaged in sub-freezing temperatures, the battery capacity will be greatly reduced and will not achieve full range. Pre-condition the vehicle by turning on the heater while the car is still plugged in and wait several minutes prior to driving while the vehicle is still connected to the charger to maximize range in cold weather.

Charge at the right time of day - Night-time charging is best since the strain on the electric grid is often the lowest. Consequently, some local electric utilities provide special rates for off-peak charging. Many EV chargers have smartphone apps and network capabilities that allow users to program charging for certain times of day to get the most economical power.

Use an ENERGY STAR®-certified charger - With more than 240 unique models from more than 17 manufacturers, using a certified ENERGY STAR® EV Charger assures:

o Energy Savings - EV chargers are typically in standby mode (i.e., not actively charging a vehicle) for about 85% of the time. During this time, certified chargers provide the same functionality as non-certified products but use 40% less energy in standby mode.

o Safety - Not all EV chargers are safety certified, including some from large online and storefront retailers. All ENERGY STAR-certified chargers are tested for safety by a nationally recognized testing laboratory.

o Smart Technology - Most ENERGY STAR certified EV charger models are networked, allowing for remote power monitoring and control of the charging state of the connected vehicle. These smart grid-ready products allow some households and property managers to participate in special energy programs offered by some local electric utilities.

Along with Southwest Public Power District, Nebraska Public Power District wants to help you efficiently and safely get from point A to point B on the road. They may also provide EnergyWiseSM or other incentives to optimize charging your EV.

Buying products that bear the Energy Star label is a surefire way to save electricity around the house. But the government doesn’t require energy-efficiency labels for ovens. So it’s up to you to conserve energy as you prepare your meals. Here’s how: · Use the microwave rather than the conventional oven whenever you can. Microwaves use half as much energy as the oven and cook food faster. · Preparing a small meal? Cook it in a portable appliance like an electric frying pan, grill or toaster oven. These small appliances eat up about two-thirds less electricity than an oven’s broiler. · Cook as much of an oven-baked meal at once as possible. Variations in heat of 25 degrees in either direction will still brown your food nicely. · Skip the preheating, especially when broiling or roasting. · If you need to rearrange your oven shelves, do it before you turn the oven on. That helps you waste less heat by opening the door of a heated oven—and it can prevent burns. · Avoid opening the door while your food is cooking. · Wipe up minor oven spills with a damp cloth and use the oven’s self-cleaning cycle only for major messes. And when you need the self-cleaner, run it right after you prepare a meal when the oven is already hot. · And, of course, never use an electric oven as a room heater or to dry damp clothes.

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.
