Spring into savings: the benefits of window replacement for your home
If the spring season gets you excited to spruce up your home, then it’s the perfect time of year to consider window replacement. Not only can new windows give the exterior of your home a boost in curb appeal, but they can also improve your home’s energy efficiency. The more energy efficient your home is, the lower your energy bill. In fact, when single-pane windows are replaced with ENERGY STAR® rated windows, households see an average drop in their energy bill of 13%! That can really add up over a year. Plus, with more or improved natural light, it’ll feel like the interior of your home got a little beauty boost, too. So, let’s explore different energy efficient windows, materials and a few energy-focused features that can transform your home.
Types of energy efficient windows: Double-pane vs. triple-pane
Double-pane and triple-pane refer to the number of panes of glass in a window. So, double-pane windows have two panes of glass and triple-pane windows have three layers of glass. In between each layer, there is often argon gas, which provides a kind of insulation, creating more indoor comfort while taking some of the load off your heating and cooling system.
Today’s windows have come a long way, and double-pane windows are now the norm. So, while triple-pane windows are more expensive and may not be in your budget, that’s ok. You’re still going to get that added energy efficiency with double-pane options.
You can also use different pane windows in different areas of your home. For instance, triple-pane windows are going to provide better temperature control in north- or east-facing rooms. They’re also a superior choice in more extreme climates (high heat and/or frigid temps) because of their ability to decrease thermal transfer. Another benefit of triple-pane windows that might be worth the extra investment to you is their increased ability to reduce sound compared to double-pane windows.
Window feature options to improve energy efficiency
Once you’ve decided if you’re going with double-pane or triple-pane windows, then you get into some of the really fun stuff — the energy-saving features! Here are some options to consider.
ENERGY STAR certified
Look for the blue ENERGY STAR label or ask your window replacement consultant about their ENERGY STAR certified products. All ENERGY STAR products have been independently certified and verified to perform at levels that meet or exceed energy efficiency guidelines set by the U.S. Environmental Protection Agency. Not only that, ENERGY STAR also provides information on the best products for your climate zone. (Find your climate zone here.)
Low-e coating
If you’ve ever felt the blazing sun heat up a room through a nearby window, then you’ll appreciate the effects of a low-e (short for low emissivity) coating. This type of thin glass coating minimizes heat transfer by reflecting infrared heat, which keeps your home cooler in the summer and warmer in the winter.
Gas fills
We mentioned earlier that double-pane and triple-pane windows often contain argon gas in the space between the panes. You might also see krypton used. Both types of gas fills improve insulation and reduce heat transfer.
Warm edge spacers
The seams — or edges — where multiple panes of glass meet are notorious spots for air to easily enter or escape. A warm edge spacer, however, is designed to fit in the area where edges meet in order to reduce heat flow and condensation, improving energy efficiency and preventing mold buildup.
Choose the right window materials for durability and energy efficiency
Now that we’ve covered some important features of energy efficient windows, let’s take a look at window frames.
Vinyl windows
Vinyl windows are a great high-quality, affordable option. If you’re on a budget, go with vinyl. Not only are they low maintenance, but they’re also resistant to warping, fading and cracking, which is going to help you save money in the long run. Plus, they’ll give you an added energy efficiency boost because vinyl is a strong insulator.
Fiberglass windows
Fiberglass windows will definitely set you back more cost-wise than vinyl windows, but they’re also going to provide a more polished look with a healthy dose of added strength. Those extreme climates we mentioned earlier? Fiberglass is the go-to choice there (though it can be used anywhere). Because fiberglass window frames experience almost zero expansion or contraction, there is less risk for seals to fail, improving overall energy efficiency.
Wood windows
If you’re looking for the ultimate customization and aesthetic lift, look no further than wood windows. Also energy efficient and durable, the main draw to wood windows is in their design. You’ll find aluminum elements on the exterior to protect your home and windows from weather, rot and corrosion. But on the inside, go wild making all your interior design dreams come true!
Increase natural light without increasing the temperature
New windows allow you to maximize natural light penetration into your home. Whether you’re in the market for picture windows, bay windows or even sliding glass doors, the increased natural light can totally transform the look and feel of a room. And, as mentioned earlier, window glass technology and materials have advanced so much that adding more natural light doesn’t mean adding more heat from the sun. If you’re feeling extra daring, ENERGY STAR also offers energy efficient skylights.
Keep your home’s curb appeal top-notch
It’s no surprise that spring is the most popular time of year for people to buy and sell homes. New windows are a big plus for potential buyers because of the financial savings that accompany their energy efficiency. Even if there are no moves in sight, window replacement is a great way to increase the value of your home while also lowering your energy bill and reducing your carbon footprint.

14 ways to get a more energy efficient lawn, garden & home
Temperatures may be rising, but that doesn’t mean your energy bill has to go up too. There are lots of great ways to create a more energy efficient environment inside and outside your home. Keep these tips in mind for a healthier lawn, a happier garden and a cooler home.
It’s raining energy savings: how to reduce water waste
Overwatering, evaporation, runoff and water hogs (aka the flora that love to soak up as much water as they can) account for a ton of water waste during the spring and summer months. In fact, the Environmental Protection Agency estimates that as much as 50% of the household water we use outdoors is lost to these factors and others, like wind and inefficient irrigation methods.
Collect rainwater.
Don’t let a good gully washer go to waste. Set up a rain barrel outside, or even just empty watering cans and buckets, to capture those April showers for all your soon-to-arrive May flowers.
Watch how you water.
Ever driven or walked by a house where the street and driveway seem to be getting more water than the plants? That’s money down the literal drain. Whether you have a high-tech irrigation system or prefer a more old-school sprinkler, make sure you’re watering the right things at the right time and in the right amount.
Set your alarm to water o’clock.
Reduce water evaporation by watering at the coolest times of day, either first thing in the morning or after the sun has gone down.
Make mulch your best friend.
Spread mulch around the base of trees and planting beds to limit water evaporation, reduce erosion and slow the growth of notoriously thirsty weeds.
Plant, grow & mow
Even if your green thumb is more light mint than rich emerald, there are still plenty of opportunities to keep your lawn and garden energy efficient ecosystems.
Check your plant hardiness zone.
Changing weather patterns and conditions may mean that your plant hardiness zone, the regional area where perennials are most likely to thrive, has changed. By planting according to your zone, not only do your perennials stand a better chance at survival, but you’ll also be growing in a more energy efficient way. Find your zone using the U.S. Department of Agriculture plant hardiness zone map.
Try your hand at homegrown food.
What you spend in sweat equity, you make up with delicious seasonal fruits and vegetables and fewer trips to the grocery store. More people these days are also getting creative and resourceful by using their front yards for produce gardens.
Don’t mow so low.
One of the easiest ways to reduce water waste in your yard is to raise the blade of your lawn mower. When you give your yard a buzz cut or mow too often, the grass dries out more quickly, leaving your lawn longing for a drink. Taller blades of grass provide shade for each other and retain more water. If you use a landscaper, communicate this to them and adjust your mow schedule accordingly, especially as the peak summer months roll in.
Backyard bliss
What’s better than a cookout? Not much! Turn your backyard into an energy-saving springtime hangout.
Shine some light with LEDs and solar.
Take a walk around the outside of your property and look for any pathway lights, security lights or landscaping lights that you could replace with LED light bulbs or solar-powered alternatives. It’s a quick, easy and affordable way to make your home more energy efficient.
Grill and chill.
Make memories, save energy. Fire up the grill, enjoy some cool summer sides and salads and take in the night sky under LED-powered string lights. No oven means no extra heat inside and less air conditioning for a couple of hours.
Air-dry laundry.
Doing laundry probably doesn’t count as “bliss,” but using your dryer less can lead to some blissful energy reductions! And nothing beats the drying power of midday sun. It’s better for your clothes, sheets and towels, plus you’ll get to enjoy that lovely springtime scent only Mother Nature can manufacture.

We recommend an HVAC tune-up twice a year, before winter and before summer. Knock out your HVAC tune-up now with a $50 rebate. Search our Quality Contractor Network for free to find a TVA-vetted heating and cooling pro.
Clean your filters.
If you can’t remember the last time you changed or cleaned the filter in your washing machine, dryer, dishwasher, refrigerator water dispenser, even your vacuum or pool, then now is the time. Basic maintenance leads to lower energy use (and a lower energy bill), and you’ll also extend the life of your appliances, avoid costly home repairs and enjoy a more comfortable living environment. Check your appliance manuals or find them online for cleaning instructions.
Change the direction of your ceiling fans.
Got 30 seconds? Look for a little switch on your ceiling fans and make sure it’s set to counterclockwise. This creates a downdraft to help you feel cooler without lowering the thermostat. Don’t forget to turn off the fan when you leave the room.

10 Earth Day challenges that give the planet (and your wallet) a break
We’re all about keeping sustainability simple and fun here at TVA EnergyRight. So this Earth Day, on April 22, we invite you to take the Earth Day Challenge. We’ve rounded up 10 eco-conscious actions you can take to reduce your environmental footprint. Download the Earth Day Challenge Checklist so you can mark your progress as you go. Read on to learn more about each challenge and why it matters to the planet and your bottom line.
What is Earth Day?
For over 50 years, people around the world have observed Earth Day on April 22. Today, more than a billion people recognize the day as an opportunity to practice new planet-friendly behaviors and to create global, national, state and local change. Ready to join 1,000,000,000 new friends in starting new energy-saving habits?
10 planet-friendly actions that won’t bust the budget
Reducing your impact on the environment doesn’t have to be expensive or inconvenient. Small, consistent actions over time can make a big difference — not just to the planet, but also to your home energy bill. Saving money and helping the environment — we give that two green thumbs up! Let’s jump into these challenges.
1. Complete the free DIY Home Energy Assessment.
Have you ever wondered about all the factors that make up your monthly energy bill? Your insulation, your HVAC system and even the tiny space between your walls and outlet covers play a role in your home’s total energy use.
TVA EnergyRight offers a free DIY Home Energy Assessment that lets you walk through your home at your own pace and at the time that’s most convenient for you so you can discover exactly how your home is using or losing energy. You’ll get a full customized report at the end of the assessment highlighting energy-saving improvements you can make to lower your energy bill. Plus, you’ll get a free $10 home improvement store gift card and one of our energy-saving kits in the mail.
Or, if you’d rather an expert assess your home’s savings potential, schedule a Home Energy Evaluation instead. One of our TVA-certified Home Energy Advisors will get it done.
2. Switch to bar soap.
Next time you’re running low on hand or body soap, consider switching to good ol’ fashioned bar soap. Now, before you object, remember that bar soap has come a long way — this is not your grandma’s soap! Today, there really is something for everyone.
One of the huge pros of using bar soap is that it typically uses zero plastic packaging. Since plastic is made from oil, a nonrenewable energy source, using less of it is always a good thing. That cuts back on plastic in landfills, which can take up to 400 years to break down! Plus, unlike liquid soap or body wash, bar soap is already shelf-stable, which means it contains fewer chemicals and other possible skin irritants. Now there are even shampoo and conditioner bars.
Worried about germs? Rest easy. Multiple studies have proven that bar soap is not any less hygienic than liquid soap.
3. Give your HVAC some TLC.
A well-maintained HVAC system is a happy HVAC system. Basic maintenance allows your system to run more efficiently, which will save you money on your energy bills. We recommend changing your air filter at least once every three months. And we’ll let you in on a little secret . . . basic air filters work just fine. You don’t need to dish out extra cash for the fancier ones with all the bells and whistles.
We also recommend getting your HVAC system serviced twice a year — once in the spring and once in the fall. This ensures you go into summer with a properly functioning air conditioner and into winter with your heat ready to roll. So, right now is the perfect time to schedule your spring tune-up, and when you do, you can get a $50 rebate!
If your HVAC system is 10 or more years old, struggles to keep up with your home’s demand or you experience higher-than-normal energy bills, it might be time to consider upgrading your system. TVA EnergyRight offers a wide range of money-saving rebates on HVAC system upgrades, including everything from mini-splits to geothermal heat pumps. Check out all our rebates.
4. Plug devices into a power strip, then turn the power strip off when you’re done for the day.
How often do you go around unplugging computers, TVs or phone chargers from the wall when you’re done for the day? Probably never. But those devices and electronics are still using energy, even when they’re off. We call this passive energy use “vampire energy.”
To stop vampire energy in its tracks, we recommend using a power strip. Everything gets plugged into the power strip instead of directly into the wall. Then, when you’re done for the night, all you have to do is turn off the power strip.
If you want to take the energy savings one step further, consider a smart power strip. It works just like a traditional power strip, only a smart power strip senses when devices have gone into standby mode or aren’t being used and cuts power to them automatically.
5. Enroll in TVA’s Green Switch to support solar power in our region.
For as little as $2 a month, you can support solar power in the Tennessee Valley by enrolling in Green Switch. With Green Switch, you can match some or all of your electricity use in $2 blocks (each block equals 200kWh) of solar-powered electricity. That’s enough power to run your refrigerator for six months, or the equivalent of saving the carbon emissions of 20 gallons’ worth of gasoline!
Solar power is a renewable energy source with zero carbon emissions. So, when you support Green Switch, you’re making it possible for all Valley residents to breathe cleaner, fresher air. You can enroll or unenroll in Green Switch whenever you like.
Want to know if your local power company offers Green Switch? Check the list and get in touch with your local power company to sign up.
6. Celebrate Meatless Mondays with plant-based meals.
What’s meat got to do with saving energy? A lot, actually! A whopping 75% of Earth’s agricultural land is dedicated to livestock production.1 This industry creates more carbon emissions than the plane, train and automobile industries combined.
But just skipping beef at one meal every Monday for a year reduces your carbon emissions by the equivalent of driving 348 miles.2 You could power an iPhone for six months with the same amount of energy it takes to produce just one quarter-pound burger!3 So, if you want to shake up your meals, save energy and reduce your grocery bill, give Meatless Mondays a try.
7. Opt out of junk mail.
Tired of opening the mailbox to only find credit card and car insurance offers? Now you can save trees and cut the credit card clutter by opting out of junk mail. Just like adding your phone number to a do not call registry, you can take similar action with your mail. Visit DMAchoice.org and Optoutprescreen.com to add your address.
8. Use the dishwasher instead of washing dishes by hand.
Are you ready to have one of the biggest energy myths of all time busted? Here goes: You do not save energy or water by washing your dishes by hand. Seriously! An ENERGY STAR® dishwasher uses less than four gallons of water per cycle. A running faucet? Four gallons of water every two minutes. That’s not to mention the energy it takes to heat the water and pump it to your home. You don’t need to wait until your dishwasher is full to run it either. Today’s dishwashers are so much more energy efficient that you will still use less water and energy running a half-empty load than washing by hand.
Think you can handle one more debunked energy myth? Hold onto your hats, pre-rinsers, this one’s for you! The most energy inefficient thing you can do when it comes to getting your dishes clean is to pre-rinse them. Not only does it take water and energy to do the pre-rinse, but then more water and energy are needed for the dishwasher. So, this Earth Day, we challenge you to take your dishes straight from the dinner table to the dishwasher!
9. Switch to garbage bags made from recovered plastic.
This might be hard to believe, but plastic garbage bags are a relatively new addition to the trash disposal scene, gaining popularity only around the 1950s. And unfortunately, the amount of plastic they use really stinks. Plastic garbage bags are typically made from virgin plastic and are single-use. Basically, they’re designed to be used one time before they head to the landfill — a place where it is pretty unlikely they’ll be recycled.
Life is a lot different than it was in the 1950s, and most of us probably aren’t giving up plastic garbage bags for good. So what’s a helpful alternative? Switch to garbage bags made from recovered plastic. A combination of recycled and reclaimed plastic, recovered plastic bags are just as strong as your average plastic garbage bags and usually come in a recyclable box made of recycled cardboard or paperboard. Plus, they’re available at your favorite grocery store or major online retailer.
10. Don’t mow so low.
Overwatering, evaporation, runoff and water hogs (aka the flora that love to soak up as much water as they can) account for a ton of water waste during the spring and summer months. In fact, the Environmental Protection Agency estimates that as much as 50% of the household water we use outdoors is lost to these factors and others, like wind and inefficient irrigation methods.
One of the easiest ways to reduce water waste in your yard is to raise the blade of your lawn mower. When you give your yard a buzz cut or mow too often, the grass dries out more quickly, leaving your lawn longing for a drink. Taller blades of grass provide shade for each other and retain more water. If you use a landscaper, communicate this to them and adjust your mow schedule accordingly, especially as the peak summer months roll in.

15 ways to save energy at home when you’re on Spring Break
Whether your spring break is taking you somewhere warm and toasty or cold and snowy, don’t miss an opportunity to save energy at home while you’re away. A little bit of quick and easy at-home prep before you leave can mean a lower energy bill when you return. And a few extra bucks in your bank account might just be the best vacation souvenir of all. We’ve rounded up 15 ways to power down your home so you can fully relax and unwind this spring break.
Give your HVAC system a break, too.
Hey, maybe your HVAC system would love a little spring break, too? Since heating and cooling your home can make up as much as 55% of your total household electricity use, it’s also a great place to find energy savings. Here are a few things you can do to let your HVAC get some R&R.
1. Set your thermostat to 55° F in the winter or 85° F in the summer.
The weather in the Southeast is unpredictable. When you leave for spring break it could be 30° F outside or it could be 70° F. It’s anybody’s guess! That being said, adjust your thermostat accordingly. When it’s warmer outside, set your thermostat to 85° F. For every degree above 72° F you can save up to 3% on your energy bill. Now if it’s cold out still, set your thermostat to 55° F. Not only will you save a ton of energy, but you can also rest easy knowing that heat will still flow and your pipes will be protected during a freeze. If you’ve got a smart thermostat, use vacation mode to set it and forget it.
Just remember, when you return home and want to recool or reheat the house, only set it to your desired temperature. Dropping the temperature as low or as high as it can go won’t make your HVAC system work faster, but it will make your system work harder for longer. Not only could that damage your system, but it will also drive up your energy bill.
2. Unplug space heaters.
If it’s still space heater season in your area by the time spring break rolls around, unplug those guys before you go. Space heaters are energy eaters, and even when they’re off, they’ll continue to use energy just by being plugged into an outlet. In general, whether you’ll be gone for eight hours or eight days, never leave a space heater on in an unoccupied home. It’s a fire hazard.
Keep your energy bill out of hot water.
3. Drop your water heater thermostat to its lowest set point.
If no one’s home, nobody needs hot water, right? Go ahead and give yourself some extra savings by turning your water heater thermostat down to its lowest setting. For older electric water heaters, look for a small plate on the front of the machine that unscrews. You’ll find the thermostat dial in there. If you have a newer, more energy efficient model, set the thermostat to vacation mode. For gas water heaters, you’ll want to check your user manual. It’s important to remember, however, that this might be a tip to skip if there’s a chance of freezing temperatures while you’re away.
Keep food fresh and frozen.
4. Set the refrigerator thermostat to 35° F–38° F and the freezer to 0° F–5° F.
If you’ve never checked your refrigerator and freezer thermostats (or if it’s been awhile), take 15 seconds to give them a quick glance. For optimal energy efficiency, set the refrigerator thermostat to 35° F–38° F and the freezer to 0° F–5° F. Maintain these temperature ranges year-round to keep food fresh, safe to consume and delicious. (Find more energy-saving tips and advice you can use all year.)
Stop vampire energy and give your electronics a breather.
While we don’t have advice on how to decrease kiddos’ screen time on spring break, we can at least tell you how to give your home a break from all the devices. Here’s the thing: If it’s plugged into an outlet, it’s using energy, even if it’s not technically “on.” We call this “vampire” energy, because it’s sucking up energy — and money — whether the device, machine, etc. is in use or not. So, before you head out of town, do a quick sweep for vampires first!
5. Unplug all small electronic devices, e.g., de/humidifiers, kitchen gadgets, printers.
6. Unplug all TVs, gaming consoles, entertainment devices, computers and laptops.
7. Unplug all power adapters and charging devices.
8. Unplug the microwave, toaster, coffee maker and appliances with an electronic clock.
Leave only necessary lights on.
9. Turn off indoor and outdoor lights.
While it’s not a bad idea to leave a light or two on when you’re away, you also don’t need to keep the house lit up like the Fourth of July! Keep a few strategic lights on but turn off the rest. If you have timers or light sensors, you can set those up, too, so that you only have certain lights on, at certain times.
Block out the sun.
10. Close all curtains, drapes and blinds.
This is another tip that only takes seconds to complete. While you’re going around the house searching for things to unplug, close curtains, drapes and blinds, too. By blocking out heat-producing sunlight, you can maintain a cooler temperature inside. If you’re traveling during warmer months, make sure to check out our tips for saving energy during the toastiest times of the year.
Don’t forget these miscellaneous items.
Keep the energy-saving shutdown going and knock out just a few more remaining things!
11. Turn off ceiling fans and personal fans.
12. Unplug the hot tub heater or drain/winterize hot tub.
13. Turn off or lower the swimming pool heater. (Leave the pump on.)
14. Unplug air conditioners if they’re not needed for humidity control.
15. Unplug landscaping water features if they’re not needed for aquatic life.

7 free and easy fixes to keep your home warmer for less this winter
Cold weather can do a number on your winter energy bills, especially when temperatures dip into the teens or lower. But it doesn’t have to. There are some simple —and free — steps you can take to help manage your energy bill during the coldest months of the year. Plus, you can access free home energy education and tips year round when you visit the TVA EnergyRight® website. We’re here to help you stay warm, save energy, and keep your energy bills under control.
1. Set your thermostat to 68°F or lower.
Skip the next battle in your home’s thermostat war by getting everyone on board with using 68° F as a baseline. Here’s why that matters: Heating and cooling your home makes up about 31% of your total electricity use. So, the more attention you focus on improving your heating system’s energy efficiency, the more energy and money you’ll save. If you leave the house for eight or more hours, move that dial back even further. It could save you upwards of 10% annually. As an added bonus, you might just also enjoy better sleep. Studies show that sleeping in cooler temperatures can improve sleep quality.
2. Leave air vents open and unobstructed.
Pop quiz! True or false: Closing vents in unused rooms saves money on heating. Well, if you guessed true, you’re not alone. But the answer is actually false! This is one of the most common home energy myths we hear. While it seems like shutting off the flow of heat to a room that isn’t being used would save energy and redistribute the heat to other rooms, it actually doesn’t. Here’s what could happen instead:
Damage to your HVAC system
Yikes. Not only can too many closed registers (HVAC lingo for air vents) cause damage to your compressor, but pressure can start to build in your air ducts, which can turn tiny leaks into a big problem.
Lost energy efficiency
The size of your HVAC system is designed to provide the right amount of heating and cooling to your home. So when air vents get blocked off, your system is still going to produce the same amount of air, only now it doesn’t have as many places to flow. That creates pressure and will cause your system to work harder, meaning more electricity use, and you guessed it, a higher utility bill.
Mold and mildew growth
Closed registers can cause condensation to form in the air duct, and that moisture can become the perfect breeding ground for mold and mildew.
3. Take advantage of the sun.
You know who really loves to help people save energy? Mother Nature herself! On those bright, sunny winter days, pull back the curtains, open the blinds and let the sun pour in. Enjoy the extra light and warmth with no increase to your energy bill. At night, close everything up again for a little added protection from the cold.
4. Weatherstrip doors and windows, DIY style.
A little gap here, a little gap there—if you think those drafty spots around doors and windows aren’t that big of a deal, think again. Even just a 1/8-inch gap around the entryway of a door is equivalent to drilling a five-inch hole through the outside wall! That’s a ton of space for cold air to slip in and your heat (and money) to slip out.
While caulk and weatherstripping may set you back about $20, you can also try these no-cost tips in a pinch:
- Plastic grocery bags. Flatten out a plastic garbage bag, then roll it up longways. You may need several depending on the window or draft. Open the window and fill any gaps where insulation is missing or damaged with the grocery bag rolls. Then, shut the window.
- Cotton swabs. A rattling window is not only annoying, but it’s usually a sign of a draft. Take an everyday cotton swab and fold it up slightly at the edges, forming a wide u-shape. Place the cotton swab u-shape side up in any gaps where the window meets the base.
- Old sheets or towels. Use old sheets, towels or blankets to block drafts at window sills. Roll them up longways for a quick and easy doorstop.
5. Avoid using emergency heat unless it’s a true emergency.
Emergency heat is only for emergencies! It is not for daily use. The only time you should use emergency heat is if your primary heat pump and auxiliary heat (the heat that automatically turns on if the heat pump malfunctions) go out. Emergency heat, which has to be manually turned on and off, costs significantly more than your everyday heat and will drive up your energy bill.
6. Reverse the direction of your ceiling fan.
Yes, ceiling fans can help you feel warmer! Toggle the little switch on your ceiling fans so that they rotate clockwise. This will drive warm air hovering around the ceiling back down into the room and onto your skin. (Remember, ceiling fans cool and warm people, not rooms.) Just don’t forget to set it back to rotate counterclockwise for the spring and summer!
7. Bundle up.
This one is a no-brainer, but it’s so easy to forget! Grab a hoodie, some comfy socks and your favorite blanket, and you can avoid having to crank up the heat to take off the chill. This is the perfect time to slide into your slippers so you can slide into energy savings.
Use home energy rebates when no-cost fixes don’t cut it.
Let’s face it, if your HVAC system goes belly up in the middle of an extreme winter weather event, no amount of no-cost fixes are really going to cut it. But investing in a new heating system, replacing faulty ductwork, or beefing up your home’s insulation isn’t always in the budget. TVA EnergyRight offers a range of money-saving rebates for common home energy upgrades so that improving your home’s energy efficiency can be more affordable. Plus, all rebate-eligible home energy upgrades are completed by a TVA-vetted contractor from our Quality Contractor Network, ensuring your work is backed by TVA quality standards. We’re here to help you make winter weather energy choices that keep you warm

Renters, don’t miss these no-cost tips for a lower electricity bill.
Renters, this one’s for you! Saving energy at home isn’t just for homeowners. There are lots of simple, easy and totally free things you can do to lower your household utility costs. Because, let’s face it, unless something breaks, it’s pretty unlikely your landlord will proactively invest in costly energy-saving upgrades or repairs, like ENERGY STAR appliances or a new energy efficient HVAC system. Let’s take a look at a home’s biggest electricity users and some no-cost energy-saving hacks that can put a little extra green back in your pocket.
Heating and cooling
Heating and cooling your home accounts for about 32% of your total electricity use.1 These small actions can make a big difference, though.
Keep air vents open and unobstructed.
Your HVAC system is built to provide the proper amount of heating and cooling for a home your size. So, when you close air vents and registers, your system will still produce and distribute the same amount of heat or cool air, but only now with fewer places for that air to go. That increased pressure puts a real strain on your duct work, and it forces your HVAC system to work harder. If you have floor vents, make sure nothing obstructs their air flow, like furniture, rugs or curtains.
Set your thermostat to 68° F to 70° F during the day in the winter.
The Department of Energy estimates you can save up to 10% on your annual heating expenses when you cut the heat back 7-10 degrees for eight or more hours at a stretch — perfect for a day in the office or when you’re out of town. When you’re home, aim for around 68° F to 70° F. For every one degree you lower your thermostat, you can save around 3% more energy.
Pro tip: Returning home after a day at work or a trip? Your impulse might be to set your thermostat way beyond your desired temperature to heat your home quicker. But resist the urge to surge! This does not increase the speed at which your home will warm up, but it will put extra stress on your system and use more energy.
Avoid using emergency heat unless it’s a true emergency.
Emergency heat is only for emergencies! It is not for daily use. The only time you should use emergency heat is if your primary heat pump and auxiliary heat (the heat that automatically turns on if the heat pump malfunctions) go out. Emergency heat, which has to be manually turned on and off, costs significantly more than your everyday heat and will drive up your energy bill.
Water heating
Heating water, like for showers and the dishwasher, makes up 11% of your home’s total electricity use, so anywhere you can scale back in this area is going to make a nice impact on your bill.1
Wash clothes in cold water on the high spin cycle.
Your clothes get just as clean using cold water, so give this tip a whirl. When you wash clothing in hot water, you’ll use more electricity as your water heater works to, well, heat your water! Hot water is also harsh on clothes, which can mean having to replace clothing more often. Set your washing machine to a high spin cycle. This will ensure as much water as possible is spun out of your clothing and they’ll dry faster in the dryer.
Lower your water heater temperature to 120° F.
Most households have the temperature of their electric water heater set too high. By lowering your water heater temperature to 120° F, not only will you save money on your electricity bill (because you need electricity to make hot water) but you can also avoid burning yourself with water that is too hot.
Take shorter showers.
OK, yes, for long shower lovers this might seem impossible. But if you can reduce your shower time to 5-10 minutes, it reduces the amount of energy required to heat enough hot water for a 20-minute dip. Lower your electricity bill and avoid pruney skin — a win-win!
Household appliances: washing machine, dryer, stove & dishwasher
The way you use many household appliances, including your washing machine, dryer, stove and dishwasher, can drive up your electricity bill. These appliances account for 7% of your home’s energy use, and that’s not including the refrigerator or freezer, which we’ll get to in the next section.1
Don’t overstuff the washing machine or dryer.
Unless you’re one of those rare people who loves to do laundry, then you’re probably trying to knock out this chore as quickly as possible. But, if you’re overstuffing your washing machine and dryer, you’re creating more work for yourself — work that will ultimately lead to greater energy use.
Clothes need room to move around in the washing machine so that detergent can actually reach everything and your items can go through rinse cycles without trapping dirty water. The same logic applies to your dryer: If a dryer is packed full, there’s no room for warm air to move around and through your clothing. This leads to additional drying cycles, which will not only drive your electricity bill up but will also do a number on your clothing.
Match pot and pan sizes to burner sizes.
If you’re using a small saucepan, use your smaller burners. Large burners use more energy, and if there’s nothing there to heat, then you’re burning up easy savings.
Skip the dry cycle on your dishwasher.
Instead of using your dishwasher’s drying feature, opt to let your dishes air dry. Because, let’s be honest, even with the dry cycle, some of your dishes still come out wet! Once your dishwasher is done, crack the door and let evaporation work its magic.
Refrigerator & freezer
Just this one appliance makes up 7% of your total household electricity use.1 Keep your food fresh and safe and your electricity bill low with these fridge and freezer energy conservation tips.
Reset your refrigerator temperature to 35-38° F.
Got 60 seconds? Because that’s about all you’ll need to make this free and effective change. Open your refrigerator, look for the temperature gauge and then adjust the temperature to anywhere between 35° F and 38° F. This is the most energy efficient temperature to set your fridge while keeping your food safe. When you’re done with that, head over to the freezer and set its temperature to 0-5° F.
Keep your fridge full.
High food costs can get in the way of practicing this tip, but when possible, keep your fridge full. Not overstuffed or bursting at the seams, but comfortably full, even if that’s adding a couple of gallon jugs of water. Refrigerated items need enough space for cool air to move around them, but once all your food and drinks are cold, everything works together to maintain the right temperature without too much additional energy from the appliance itself.
Lighting, TVs & computers
Between lighting, TVs, gaming systems, laptops and all the other devices in our homes, it can all add up to a decent chunk of your electricity bill, about 10%, in fact.1 Fortunately, lowering energy use in this area is as simple as the flip of a switch.
Turn off the lights when you leave the room.
It really is one of the easiest behavioral changes to practice. When you leave a room, flip that light switch on your way out even if you’ll return in a few minutes. Small habit changes like this also reinforce an energy-saving mindset. Soon you’ll be looking for ways to boost your energy efficiency everywhere!
Turn off and unplug devices.
A common energy myth is that if it’s turned off, it’s not using power. But we’re here to bust that myth! Yes, turning off your TV saves more energy than keeping it on all night after you fall asleep. But it’s still using power even when it’s off. We call that kind of energy “vampire energy,” because as long as something is plugged in, it’s sucking energy and increasing your energy bill. You’ll save more energy when you power down electronics and other devices and unplug them from their outlets. Or, if you have multiple things plugged into a power strip or surge protector, flip the switch when you’re done for the day to cut power to everything.

Heating your home and keeping clean air flowing
5. Turn the thermostat down a few degrees.
Heating your home makes up a big chunk of your monthly energy bill. According to the Department of Energy, you can save as much as 10% a year on heating and cooling by turning your thermostat down 7°F – 10°F for 8 hours a day in the fall and winter. So, find your favorite blanket and some cozy socks to start saving energy today!
6. Get your duct system professionally cleaned.
Keep clean air flowing, uncover cracks or holes in ductwork and increase the efficiency of your HVAC system when you get a professional duct system deep clean. Don’t know who to hire? Try a TVA-vetted contractor from our Quality Contractor Network. Find your next contractor.
7. Schedule an HVAC system tune-up.
Is your heating system electric? Don’t get stuck in a chilly (or even life-threatening) emergency situation this winter. Knock out your HVAC tune-up now with a $50 rebate. (Gas heat? Get your $50 rebate in the spring with an air conditioner tune-up.) Explore rebates.
8. Uncover any blocked air vents.
If there’s anything blocking your air vents — a couch, a bed, rugs, drapes, an entertainment center — it’s going to make your HVAC system work harder to keep a controlled temperature. You want unobstructed vents for maximum airflow and maximum energy savings.
9. Weatherstrip doors and windows.
A little gap here, a little gap there — those spots around doors and windows where air sneaks in and out are a bigger deal than you might think. Even a 1/8-inch gap around the entryway of a door is equivalent to drilling a 5-inch hole through the outside wall! Seal everything up with caulk and weatherstripping.
10. Kick dust bunnies to the curb.
Ductwork, bathroom exhaust fans, the back of your refrigerator — these not-so-obvious spots can be a haven for dust bunnies. All that dust makes your appliances work harder, increasing your energy bill and adding unnecessary extra wear and tear.
Saving in the kitchen
11. Use the dishwasher instead of washing dishes by hand.
An ENERGY STAR® dishwasher uses less than 4 gallons of water total per cycle compared to washing dishes by hand, which uses 4 gallons every 2 minutes! If you have an energy efficient dishwasher, then it doesn’t need to be full before you run it.
12. Skip the pre-rinse.
The energy efficiency of dishwashers has come a long way, and so has the cleaning power of dishwashing detergents. In fact, quality dish detergents can’t effectively do their job if they don’t have anything to cling to. Food scraps still need to go into the garbage or compost, but skip the pre-rinse and you’ll save water and electricity.
13. Clean the refrigerator grill and coils.
A buildup of dust and debris behind and under your refrigerator will make it less energy efficient. Vacuum and wipe down your refrigerator grill (the slatted piece below the doors or freezer drawer). Carefully remove the grill and vacuum under the refrigerator. Then, head to the back of the appliance and look for a metal panel. Unscrew it and gently vacuum the coils before reattaching the panel.
14. Pull the refrigerator slightly away from the wall.
Your refrigerator needs room in the back so air can circulate and the heat it generates has space to dissipate. Make sure there are about 2 inches between the refrigerator and the back wall.
15. Keep your freezer full and avoid overfilling your refrigerator.
A full freezer traps cold air, and a full, but not-too-full, refrigerator means air can flow and your items will stay cold.
16. Clean the oven and stovetop.
A dirty stove has to work harder to heat itself, and that’s going to drive up your energy costs. Grab some inexpensive oven degreaser spray and give the inside of your oven a good wipe down, including the bottom where grease and food can collect. Don’t forget the cooktop, especially if your appliance has burner drip pans.
17. Match pot and pan sizes to burner sizes.
Large burners use more energy. A too-small pot or pan on a large burner means you’re heating space with nothing on it and burning up easy savings.
Saving on technology
18. Unplug small appliances when they’re not in use.
Curling irons, electric razors, the air fryer and coffee pot — if you’re only using an item for a brief period of time each day, power it all the way down when you’re done and unplug it from the outlet.
19. Buy a smart power strip.
A device in standby mode is still using energy. A smart power strip detects when a device has gone into standby mode and cuts power to the device.
20. Take time off from tech.
Pick one night a week to go screen-free. Substitute TV, tablets and video games with activities that use less energy (and are maybe just as fun?) like board games, puzzles and books.
Saving on laundry
21. Air-dry laundry.
If the idea of a backyard clothesline seems like a stretch, take a quick spin around some of your favorite online stores and you’ll find dozens of stylish and affordable indoor clothes drying racks.
22. Clean the dryer vent.
A full lint trap makes your dryer work harder, and it’s also a fire hazard. Empty the lint trap after every dryer use. Twice a year, clean the full dryer vent, the part that extends from the back of your dryer to the outside of your home. This is especially important if your dryer stays in heavy rotation and/or you have furry pets.
Hitting the road
23. Rent or buy an e-bike.
Put some power behind the pedals! E-bikes give you all the fun of a traditional bicycle with less physical effort thanks to the added boost of battery power. Leave the car at home, save on fuel and head out for an adventure.
24. Try out mass transit.
Next time you’re headed to a concert, sporting event or even just a trip to the mall, hop on your area’s local public transportation. You’ll beat the traffic, save on the pricey parking and likely get to your destination for less than it would cost to drive there.
Whether you try one energy-saving tip, try all 24 or come up with more on your own, TVA EnergyRight and your local power company are here to help you take the next steps toward a more energy efficient home. Find even more resources at EnergyRight.com/Residential. Happy New Year!
Hittin’ the road for the holidays? Save energy at home even while you’re away
15 ways to save energy at home even when you’re traveling for the holidays
If you’re heading out of town this holiday season, it’s the perfect time to save some extra energy at home. Fewer people in the house = less energy used. It’s Home Alone, but without the elaborate schemes to stop the Wet Bandits. Take advantage of all the ways you can save energy and money at home even while you’re away. Check out these 15 quick and easy tips to power down your home before you board your sleigh and hit the road.
Find energy savings hiding in your HVAC.
Did you know that heating and cooling your home can account for as much as 55% of your household electricity use? That’s… a lot. But that also means just a few small things can make a big difference. Let’s check them out.
1. Set your thermostat to 55° F in the winter.
First things first: If you’ve left Grandma, Fido, or your award-winning exotic plants at home while you hop a flight to Honolulu, please leave everyone at a comfortable temperature. But if your home is unoccupied, it’s time to turn that thermostat down!
Set your thermostat to 55° F. For every degree below 72° F, you can save up to 3% on your energy bill. Not only will you save a ton of energy, but you’re also ensuring heat will still flow and your pipes will be protected should temperatures go below freezing. If you’ve got a smart thermostat, use vacation mode to set it and forget it.
Just remember, when you return home and want to reheat the house, only set it to your desired temperature. Bumping up the temperature as high as it can go won’t make your HVAC system work faster, but it will make your system work harder for longer.
2. Unplug space heaters.
Space heaters are energy eaters. Whether you’ll be gone for eight hours or eight days, never leave a space heater on when no one is home. It’s a fire hazard. But if you’re planning to be away, even for a night or two, don’t just turn your space heaters off. Unplug them. Even when off, they’ll continue to use energy just by being plugged into an outlet.
Keep your energy bill out of hot water.
3. Drop your water heater thermostat to its lowest set point.
If no one’s home, nobody needs hot water, right? So go ahead and give yourself some extra savings by turning your water heater thermostat down to its lowest setting. For older electric water heaters, look for a small plate on the front of the machine that unscrews. You’ll find the thermostat dial in there. If you have a newer, more energy efficient model, set the thermostat to vacation mode. For gas water heaters, you’ll want to check your user manual. It’s important to remember, however, that this might be a tip to skip if there’s any chance of freezing temperatures while you’re away.
Keep food fresh and frozen.
4. Set the refrigerator thermostat to 35° F–38° F and the freezer to 0° F–5° F.
If you’ve never checked your refrigerator and freezer thermostats (or if it’s been awhile), take 15 seconds to give them a quick glance. For optimal energy efficiency, set the refrigerator thermostat to 35° F–38° F and the freezer to 0° F–5° F. Maintain these temperature ranges year-round to keep food fresh, safe to consume, and delicious. (Find more energy-saving tips and advice you can use all year.)
Stop vampire energy and give your electronics a breather.
Everything that’s plugged into an outlet in your home is using energy, even if it’s not technically “on.” We call this “vampire” energy, because it’s sucking up energy — and money — whether the device, machine, etc. is in use or not. So, before you leave for vacation, do a little vampire hunting around your home! Your printer, the air fryer, the gaming system your kids aren’t allowed to take? Unplug it all!
5. Unplug all small electronic devices, e.g., de/humidifiers, kitchen gadgets, printers.
6. Unplug all TVs, gaming consoles, entertainment devices, computers and laptops.
7. Unplug all power adapters and charging devices.
8. Unplug the microwave, toaster, coffee maker and appliances with an electronic clock.
Leave only necessary lights on.
9. Turn off indoor and outdoor lights.
While it’s not a bad idea to leave a light or two on when you’re away, you also don’t need to keep the house lit up like, well, a Christmas tree! Keep a few strategic lights on but turn off the rest. If you have timers or light sensors, set those up so that you only have certain lights on at certain times. Don’t forget to unplug any outdoor decorations like inflatables and holiday lights.
Let in some sun.
10. Open curtains, drapes and blinds in sunny rooms.
This is another quick and easy tip that only takes seconds to complete. While you’re going around the house searching for things to unplug, open curtains, drapes and blinds in rooms that get a lot of sun. By allowing heat-producing sunlight in during the day, you can maintain a warmer temperature inside. This will help prevent your heating system from kicking on unnecessarily.
Don’t forget these miscellaneous items.
Keep the energy-saving shutdown going and knock out just a few more remaining things!
11. Turn off ceiling fans and personal fans.
12. Unplug the hot tub heater or drain/winterize hot tub.
13. Turn off or lower the swimming pool heater. (Leave the pump on.)
14. Unplug air conditioners if they’re not needed for humidity control.
15. Unplug landscaping water features if they’re not needed for aquatic life.

Make the holidays merry and bright while keeping your energy bill in check
Make the holidays merry and bright while keeping your energy bill in check.
The holidays, and winter specifically, can mean higher energy bills. Maybe you’re hosting fun gatherings or welcoming out-of-town guests. Maybe the kids are home from school. Or maybe dropping temperatures have you reaching for the thermostat more than usual. It can be hard to keep your energy bill under control this time of year, but we’re here to help keep things jolly without costing you more jingle.
The host with the most (energy savings).
‘Tis the season for at-home socializing, especially if family or friends plan on staying with you. More people means more showers, more laundry, more dishes and, of course, more opinions about the “right” temperature to set the thermostat. While you may not be able to get away with using less energy while hosting overnight guests, you can at least take some measures to reduce the impact of additional energy-users.
Try the “set it and forget it” thermostat approach.
Everyone’s preferred indoor temperature is different. Rather than drive yourself crazy adjusting the thermostat all day (which makes your HVAC system work harder), take a “set it and forget it” approach, aiming for 68° F or cooler. Body heat goes a long way, and with more people in the house, you can probably go a few degrees lower than your normal setting. For every degree below 72° F, you can save up to 3% on your energy bill.
Unplug space heaters.
Space heaters are energy eaters. But they’re also a game changer in older homes with drafty rooms or spotty insulation. If you have space heaters, make sure someone is always home when they’re on. Unattended space heaters are a big-time fire hazard. Make sure you remind your guests to turn them off or unplug them when they’re not in use. Even when a space heater is off, it will still continue to use energy because it is plugged into an outlet.
Wash clothes in cold water, and don’t overstuff the dryer.
Your washer and dryer may be working overtime, but a gentle request to guests can help manage energy use. It takes electricity to create hot water, so encouraging guests to wash on cold will not only keep more hot water available for showers and hand washing, but it’ll also get clothes just as clean.
A too-full dryer requires a longer drying cycle, which means more electricity is used. Clothes need to have enough room to tumble so that warm air can get between them. Break up larger wash loads into smaller drying loads, and separate heavier items, like blankets, sheets and bath towels, from clothing. (Don’t forget to clean the lint trap. Your guests may forget or feel uncomfortable tinkering with your machine. A full lint trap not only makes your dryer work harder, but it’s also a fire hazard.)
Don’t pre-rinse dishes before putting them in the dishwasher.
This might become a hotter debate than politics over pot roast, but the truth is, the energy efficiency of dishwashers has come a long way, and so has the cleaning power of dishwashing detergents. In fact, quality dish detergents can’t effectively do their job if they don’t have anything to cling to. Food scraps still need to go into the garbage or compost, but skip the pre-rinse and you’ll not only save a ton of water but you’ll also save the energy that would have been used to heat your rinse water.
This might also sound crazy, but it’s true. If you have an energy efficient dishwasher, then it doesn’t need to be full before you run it. An ENERGY STAR® dishwasher uses less than 4 gallons of water total per cycle compared to washing dishes by hand, which uses 4 gallons every 2 minutes!
It’s the holidays and the kids are home from school.
If you don’t have out-of-town guests, but your permanent residents (ahem, your kids) are out of school, at home and using energy like it’s going out of style, we can help… at least for a few minutes.
Try a holiday-lights-only night.
Tap into the magic of the holidays while also saving some energy. Turn off all the lights in the house except for any indoor holiday lighting. Eat a picnic dinner, read bedtime stories or make shadow puppets under the sparkly glow.
Bored teenagers? Send them on an energy-saving mission.
TVA EnergyRight offers a free, online DIY Home Energy Assessment. During the assessment, your kids will move through the house (avoiding any places you deem off limits) to find out how your home uses and loses energy. At the end of the assessment, you’ll get an easy-to-read report with customized energy improvement recommendations specific to your home, plus an energy-saving kit and a $10 home improvement store gift card. Often, these reports include easy DIY home energy upgrades that older kids could tackle, like putting LED light bulbs in lamps and adjusting the temperatures of the refrigerator and freezer.
Create greener, cleaner challenges.
For a lot of kids, the holidays mean gifts. With more physical goods coming into the home, it’s a great time to challenge everyone in the house, not just children, to practice some simple sustainability skills. Try the “One In, One Out” game where for every new gift someone receives, they find a gently used toy, game, article of clothing or accessory to donate. Research as a family where you want to donate everything you’ve collected.
Gifts also usually mean lots of shipping boxes and packaging. Find creative uses for the boxes, like building a box fort or a doll house. Make a game out of breaking down the boxes and work together to make sure they get recycled.
Energy-saving seasonal hacks.
Give yourself the gift of a less stressful holiday season with a few basic energy-saving winter hacks. After all, an ounce of prevention is worth a pound of cure.
Leave air vents open and unobstructed.
Shutting off the flow of heat to a room that isn’t being used might seem like it would save energy by redistributing the heat to other rooms, but that’s not quite how it works. Too many closed registers (HVAC lingo for air vents) can cause damage to your HVAC compressor, allowing pressure to build in your air ducts, which can turn tiny leaks into a big, big problem.
Plus, the size of your HVAC system is designed to provide the right amount of heating and cooling to your home. So when air vents get blocked off, your system is still going to produce the same amount of air, only now there are fewer places for it to flow. That creates pressure and will cause your system to work harder, meaning more electricity, and you guessed it, a higher utility bill.
Finally, holiday decorations can often mean furniture and rugs get temporarily rearranged. Double check that you don’t have anything blocking your air vent — like a couch, drapes, an entertainment center or Christmas tree skirt — to ensure maximum air flow and maximum energy efficiency.
Weatherstrip doors and windows.
A little gap here, a little gap there — if you think those drafty spots around doors and windows aren’t that big of a deal, think again. Even just a 1/8-inch gap around the entryway of a door is equivalent to drilling a five-inch hole through the outside wall! That’s a ton of space for cold air to slip in and your heat (and money) to slip out. Fortunately, weatherstripping is a super simple and affordable DIY project you can knock out quickly. Most home improvement stores carry door sweeps for larger gaps at the bottom of doors and weatherstripping to seal windows and the sides of doors.
Find a contractor before there’s a home energy emergency.
Most people only find out they have an issue with their water heater or HVAC system when it breaks. Combine that emergency situation with the stress of the holidays or house guests and you might find yourself in a real-life nightmare before Christmas.
Get ahead of any unplanned seasonal snafus and find a contractor now that you can have on speed dial in case of emergency. TVA EnergyRight and local power companies provide customers with free access to the Quality Contractor Network, where you can find licensed and insured contractors vetted by TVA to perform home energy upgrades, like repairing or replacing an HVAC system or water heater. Plus, every Quality Contractor Network contractor can help identify any home energy rebates you may be eligible for through our rebates program and connect you to the affordable financing options we offer.

From Amps to ZEV: Electric Vehicle terms you need to know.
TVA EnergyRight presents your Ultimate Electric Vehicle Glossary: Electric Vehicle terms and lingo defined.
Keeping up with the latest electric vehicle terms, topics and trends can seem like a pretty daunting task. Luckily for you, we’re plugged into the electric transportation scene and we’re amped to share our Ultimate Electric Vehicle Glossary with you.
If electricity moves it, we’re ready to fuel it.
Our EV team has been on the road a lot over the past few months, visiting with people from all over our seven-state Valley region and sharing information about EVs.
We’ve chatted with drivers who are thinking about buying an electric car because they want to save money on gas. Others want to reduce their carbon footprint with a zero-emissions vehicle. Many enjoy the cool tech while plenty of others appreciate how quick they are.
We’ve also met commuters who want to get a little more exercise on their way to work and are considering an electric bicycle. We’ve even chatted about electric forklifts with business owners looking to provide a quieter, safer work environment for their employees while lowering emissions.
The Ultimate Electric Vehicle Glossary
This glossary is dedicated to all the great people we’ve met and all of the wonderful questions they asked about EV terms, technology and breaking news.
All-electric range (AER): The driving range of a vehicle using only power from its battery pack. Also known as range per charge.
Alternating current (AC): A term that describes the flow of electricity. In the U.S. the direction of the current changes (alternates) direction every 60 seconds (energy.gov). AC powers Level 1 and Level 2 EV chargers. (See “Battery Basics.”)
Amps (A): Also known as amperes, is a unit of measure for electrical current flow. An EV’s amp rating (or the charging station’s amp rating) is one factor that determines the maximum amount of power that can be delivered to your car’s battery. If voltage is to electricity as pressure at the gas pump is to gasoline, then amps x volts = watts all work together to measure how quickly you can fill up your battery with power.
Battery cell: The smallest unit in an EV’s battery pack. Think of it like a gallon of gas.
Battery electric vehicle (BEV): An EV that relies entirely on electric power stored in its battery pack. (See “The EV alphabet.”)
Battery module: A group of battery cells bundled together. Think of it as a few gallons of gas.
Battery management system: This system makes sure that the battery pack is operating at ideal temperatures. This helps prolong battery life and improve charging speed.
Battery pack: An EV’s battery is where the electricity that powers your car is stored. Think of it as the fuel in your EV’s “tank.”
Bidirectional charging: A technology that allows energy to flow two ways: from the electricity grid to your EV, and from your bidirectional EV charger to the grid. See vehicle to grid (V2G) (future state) and vehicle to home (V2H) (select EVs and charger stations).
Capacitor: A temporary power storage module in an electrical circuit that helps regulate spikes in power.
Charging: Fueling your EV with electricity.
Charging station: See electric vehicle supply equipment (EVSE).
Combined charging system (CCS): A standard for charging electric vehicles that can accommodate Type 1 and Type 2 AC charging and DC fast charging because it also includes a J1772 outlet. (See “Charging 101.”)
Connector: A general EV term that includes a variety of standardized plugs used to charge electric vehicles. It may include the Type 1 J1772, CCS and NACS connections.
Direct current (DC): A current that provides constant voltage and the current flows in one direction. It doesn’t change or vary over time. DC powers EV fast chargers because the direct flow of current – delivered directly to the battery – can charge more quickly. (See “Battery Basics.”)
Drag coefficient (Cd): A measurement of a vehicle’s wind resistance. The higher the drag coefficient, the harder the motor has to work to push your EV through the air. The lower the drag coefficient, the better!
Dynamic electric vehicle charging (DEVC): This future-state method of wireless charging is being tested and would enable EVs to recharge while driving on public roads (MotorTrend).
Electric vehicle (EV): Any vehicle, whether it’s a car, bicycle, boat, forklift, or scooter, that’s powered by electricity stored in batteries.
Electric vehicle supply equipment (EVSE): What you’ll need to safely charge your EV at home. It includes the cables, connectors and charging points. (See “Charging 101.”)
Fast Charge Network: TVA EnergyRight is collaborating with state agencies, local power companies and third-party charging developers to develop the Fast Charge Network, which will place fast charging stations at least every 50 miles along major travel corridors in the seven-state region.
Fast charging: Also known as Level 3 charging, it refers to the number of watts (W) that are delivered to an EV’s battery. Most fast chargers are direct current (DC) and deliver over 19 kilowatts (kW). These chargers and superchargers are most commonly found at shopping centers, travel centers, dealerships and other public locations.
Frunk: It’s that space in the front where the engine lives in gas-powered vehicles. We recommend putting your junk in it.
Fuel cell electric vehicle (FCEV): A vehicle that uses a fuel cell, usually hydrogen-based, to generate electricity that runs an onboard motor. (See “The EV alphabet.”)
Home charging: Approximately 80% of EV charging is done at home. Home charging systems – EVSEs – enable EV owners to charge up at home. It’s just as convenient as plugging in your cell phone overnight (Energy.gov).
Hybrid electric vehicle (HEV): Also known as “conventional,” “self-charging” or “mild” hybrids, these EVs use gas-fueled ICE engines and electricity-fueled motors. Hybrid vehicles — like the Toyota Prius or Honda CRV — use regenerative braking to store energy and typically have a smaller all-electric range (see “The EV alphabet”).
Incentives: You may be eligible for federal tax credits on qualified plug-in electric vehicles. Learn more about credits for clean vehicles purchased in 2023 or after at IRS.gov.
Internal combustion engine (ICE): A heat engine that converts energy from the heat of burning gasoline into torque that powers the vehicle (Car and Driver).
Inverter: An electrical device that converts electricity from a DC source to AC.
J1172: Also known as a J plug or SAE J1772, a North American standard for electrical connectors for EVs.
Kilowatt (kW): Equivalent to 1,000 watts, a unit of measure for power. Power tells us how fast energy is moving at any moment in time. (See “Battery Basics.”)
Kilowatt-hour (kWh): How many watts are consumed in an hour. (See “Battery Basics.”)
Level 1 Charging: Also known as “slow chargers” or “trickle chargers,” Level 1 chargers can plug into any standard 120-volt home wall outlet, the very same type of outlet you use to plug in your cell phone or coffee pot.
Level 2 Charging: These 240-volt chargers are just like the ones your dryer plugs into and can charge a BEV in 4-10 hours, which makes them perfect for overnight home charging.
Level 3 Charging: See fast charging.
Lithium-ion: A rechargeable battery that uses lithium ions to store energy (MIT.edu).
Miles per gallon equivalent (MPGe): An energy-efficiency metric introduced by the Environmental Protection Agency (EPA) to compare the amount of energy consumed by alternative fuel vehicles to gas-powered cars (U.S. News & World Report).
Miles per kilowatt hour (mpkWh): A measurement of an EV’s efficiency that demonstrates how an EV’s power output translates into real distance traveled.
North American Charging Standard (NACS): Previously known as the Tesla charging connector, this charging standard is used in Tesla’s Supercharger network. Ford and General Motors announced in June 2023 that their drivers will be able to charge their cars (with an adapter) at Tesla charging stations across the country. Less than a month later, seven of the world’s largest automakers announced that they’re building a new nationwide network of 30,000 electric vehicle charging stations (CBS News).
Off-peak charging: Charging your EV at times when demand for electricity is lower (typically overnight) helps maintain a healthy grid and keeps rates low for everyone.
On-board charger (OBC): A device that converts AC to DC to charge an EV’s batteries. Fast chargers bypass an EV’s OBC because they’re already DC.
Parallel hybrid: Vehicles with a parallel hybrid drive enable the engine and electric motor to work together to generate power to drive the wheels.
Plug-in hybrid electric vehicle (PHEV): A plug-in vehicle featuring a rechargeable battery, electric propulsion and regenerative braking. PHEVs also rely on a gas-powered internal combustion engine (ICE) for propulsion once the battery is depleted. (See “The EV alphabet.”)
Regenerative braking: Also known as “regen braking,” these systems are unique to EVs. They turn a vehicle’s kinetic energy (energy that relates to motion) back into electric energy. Regenerative braking helps improve fuel efficiency, reduce total tailpipe emissions and minimizes wear and tear on brakes. (See “Battery Basics.”)
Renewable energy: Energy that is generated by natural resources that are replenished faster than they are consumed such as solar, hydroelectric, and wind. Nearly 60% of TVA’s electricity comes from carbon-free sources (TVA.com).
Residential charging: See home charging.
Solid-state battery: Like lithium-ion batteries, solid-state batteries store energy; however, instead of an organic liquid electrolyte solution sandwiched between the cathodes and anodes, solid-state batteries use solid electrolytes. Some manufacturers are planning to roll them out as early as 2027. Solid-state batteries offer higher energy density, greatly extended range and faster charging times.
State of charge (SOC): The level of charge an EV battery contains compared to its capacity. 0% SOC = empty; 100% SOC = full.
Supercharger: A kind of EV charger developed by Tesla designed for fast charging.
Torque: A force that produces rotation. Motors deliver torque to the drive shaft (Merriam-Webster). Electric cars achieve maximum torque immediately and deliver instant torque to the vehicle’s wheels, which leads to excellent acceleration off the line (or from a red light).
Vehicle to grid (V2G): Power that flows from your vehicle back to the grid. This future-state capability has the potential to support the power grid during peak demand hours. (See Bidirectional charging.)
Vehicle to home (V2H): Power that flows from your EV to your home, essentially acting as a generator during weather-related power outages. (See Bidirectional charging.)
Volts (V): A unit of electrical force that measures the amount of effort required to move an ampere between two points. A higher voltage rating on a charging station equals a higher charging speed for your EV. Volts x Amps = Watts (See Amps).
Watts (W): A unit of measure for power. Power tells us how fast energy is moving at any moment in time. A kWh tells you how many of those units are consumed in an hour. Volts x Amps = Watts (See Amps).
Zero emission vehicle (ZEV): A vehicle that emits no tailpipe pollutants during operation. Battery electric cars, bicycles, motorcycles and hydrogen fuel cell vehicles are examples of ZEVs.
