7 energy efficiency tips for renters.
Here are 7 ways to stay warm and save money on utility bills (while keeping your landlord happy).
Energy efficiency for renters — and staying warm and comfortable in colder months can be tricky. As a renter, you may not be able to control your home’s insulation, heating, or windows. However, you can save money on energy bills!
Here are 7 proven energy-saving tips that are good for renters and landlords. These budget-friendly ideas will help make your rental home feel cozy and energy efficient.
1. Start with a draft check
Before you make any changes, take a few minutes to stroll through your home and feel for drafts. Here are a few common problem areas you’ll want to investigate:
- Attics and crawlspaces (and their hatches).
- Window frames, panes and sashes.
- Door jambs, sills and windows.
- Plumbing and electrical penetrations.
- Dishwasher and refrigerator connections.
- Baseboards and where walls meet the ceiling.
- Electrical outlets and vent registers.
- Recessed lights, vents and fans.
You can either use the “damp hand” or “incense trick” to test for drafts. For the first option, run your hand under cold water and then hover it slowly around the problem areas mentioned above. Or, you can light a stick of your favorite incense and hold it near the problem areas mentioned above. If the smoke wavers or pulls, you’ll have found a leak.
2. “Seal and peel” or make your own “draft snake.”
Doors and windows are two of the biggest air leak offenders. Fortunately, they’re also pretty easy to tame.
If your landlord doesn’t want to install new windows or permanent weather stripping, you can use a removable “seal and peel” caulk. This caulk makes a temporary, airtight seal around leaky windows and doors. You can easily apply it and remove it without damaging paint or door surfaces.
And whether you’re feeling quick or crafty, you can create your own draft stopper — or “draft snake” for window sills, baseboards and doors. A rolled-up towel works great if you’re in the quick camp. If you’re the crafty type, spend a few moments searching for inspiration.
3. Seal your panes with shrink window film.
Single-pane windows are common in older rental homes and apartments. They can let a lot of warm air escape and cold air come in.
That’s where seal and shrink window film comes in. Most kits include double-sided, removable tape. To complete the job, you only need scissors and a hair dryer. These kits use clear plastic film that you tape around the window frame, cut to size and shrink tight with a hair dryer.
The film improves energy efficiency by reducing drafts. Plus the kits are easy on paint and even easier to remove in spring when you feel like flinging your windows open.
If you’re not up for installing film, thermal curtains or layered drapes can also help reduce heat loss — especially at night. Just be sure to open them during the day to let sunlight warm your space naturally.
4. Plug up outlet and switch leaks
You might be surprised, but cold air can come in through gaps around electrical outlets and light switches. This is especially true for outlets on outside walls.
You can block this airflow with foam outlet insulation gaskets or socket sealers. They’re super easy to install and cost just a few dollars per pack. Simply unscrew the outlet cover, place the gasket behind it, and screw the cover back on.

5. Put a blanket on … your floor.
If your home has hardwood flooring, a quick way to insulate (and keep your tootsies warm) is by placing area rugs in high-traffic or frequently used areas like your living room or bedroom. Think of them as a cozy blanket for your floors.
Not only do area rugs help your feet stay warm, but they can also help reduce heat loss through the floor — especially if your rental is above an unheated crawlspace or basement.
6. Take it down a degree or two.
If your home has a smart or programmable thermostat, be sure to take advantage of it. If they don’t, talk to them about installing a smart thermostat, which can help reduce energy costs even more. Some local power companies may even offer incentives on purchasing a new smart thermostat.
You can layer up and set your thermostat to 68° F. You can even set it lower when you are away or cozy under quilts in the evening. If that feels too cool, try to set your thermostat just a degree or two cooler than you might consider your ideal temperature.
If your space has room-specific heaters, close doors and heat only the rooms you use most often.
7. Take a FREE DIY home energy assessment.
Discover all the ways your rented home is using (or losing) energy with our free DIY Home Energy Assessment. Plus, you’ll receive an energy-saving kit and a $10 home improvement store gift card in the mail within four to six weeks.

Air sealing and insulation tips to get your house knitted up for sweater weather.
As the golden days of summer give way to crisp autumn mornings and icy winter evenings, now is the perfect time to prepare your home for cool weather days. One of the most effective, affordable — and often overlooked — ways to stay cozy and reduce your energy bills is DIY weatherization, insulation and air sealing.
If you’d like to learn more about DIY air sealing and insulation, read on! If you’ve done all the DIY you can do, and you’re ready for the pros to roll out the insulation, you’re in the right place. You can learn more about our Quality Contractor Network right here. Or, you can use our “Find a Contractor” search tool to take the guesswork out of finding a vetted, licensed and insured contractor for air sealing and attic and wall insulation rebate projects.
What Is Air Sealing?
If you’ve ever felt a chilly draft sneak under your door or watched your heating bills climb as the temperatures plummet, your home might be telling you it’s time to seal the gaps. The good news? Not only are air sealing and insulation rebates available from TVA EnergyRight® and your local power company but there’s plenty of time to take action now.
Air sealing is the process of closing up the small cracks, gaps, and holes in your home’s building envelope — the physical barrier between the indoors and outdoors. Even if you made the air sealing rounds last fall, we recommend making this an annual event. Homes — especially older ones — may settle and shift as seasons change.
What are common “problem areas” for air leaks?
As you consider air sealing your home, pay close attention to:
- Attics and crawlspaces (and their hatches).
- Window frames, panes and sashes.
- Door jambs, sills and windows.
- Plumbing and electrical penetrations.
- Dishwasher and refrigerator connections.
- Baseboards and where walls meet the ceiling.
- Electrical outlets and vent registers.
- Recessed lights, vents and fans.
Individually, these air leaks may seem minor but together, they can add up. And in the winter, they allow your precious warm air to escape while inviting cold air to seep in. Effective insulation and air sealing can help stop energy loss in its tracks.
What’s the best way to detect air leaks?
Professional home energy auditors use a device known as a blower door to determine the amount of air entering or escaping your home. A blower door is essentially a powerful fan that pulls air out of your home, lowering the air pressure inside. This allows higher pressure outside air to flow inside. The analyst will then use infrared cameras or nontoxic smoke to visualize the air leaks in your home.
If you’d rather take a low-cost DIY approach, you can conduct a low-tech building pressurization test yourself. It won’t be as precise and a blower door test, but it’ll put you on the right path.
- Check the forecast and time your test for a windy day — this makes it easier to feel the drafts.
- Turn off combustion appliances such as gas ranges, ovens, furnaces and water heaters.
- Close all your windows, exterior doors, vents, and flues.
- Turn on exhaust fans — like bathroom exhaust fans and range hoods — or use a tight-fitting window exhaust fan to suck air out of your home.
- Light an incense stick and pass it around the edges of common “problem areas.” (See above for a full list.) Not a fan of incense? Dampen your hand and slowly move it around these areas — drafts will feel cool to your hand.
Why does air sealing matter?
Lower energy bills
When your home leaks air, your heating system has to work harder to maintain a consistent temperature. That means higher energy consumption — and higher utility bills. According to the U.S. Department of Energy, air sealing and insulation can reduce heating and cooling costs by an average of 15%, and in some cases even more.
In the Tennessee Valley, where temperatures can swing dramatically between seasons, a well-sealed home helps your HVAC system operate more efficiently and last longer.
Improved comfort
A drafty home isn’t just inefficient — it’s uncomfortable. Air leaks can lead to cold spots in certain rooms, inconsistent temperatures between floors, and the frustration that comes with being both uncomfortable and tired of spending more on heating.
When you seal air leaks and add the right amount of insulation, your home maintains a more consistent temperature year-round.
Better indoor air quality
Air sealing also helps protect your indoor air. Gaps in your building envelope don’t just let conditioned air escape — they can let in dust, pollen, mold spores — and even unwanted pests and houseguests (of the critter variety). In some cases, leaks from crawlspaces or attics can allow moisture to accumulate, resulting in a musty odor or mold growth.
Air sealing and insulation can be a big win for allergy sufferers and families with young children or older adults.
How can I fix air leaks?
You don’t have to do everything at once. Focus on key areas that can make the biggest difference:
Seal doors and windows.
- Use weatherstripping around doors and movable window sashes.
- Apply caulk to seal cracks around stationary window frames and exterior trim.
- Install door sweeps to block drafts at the bottom of exterior doors.
Address the attic and crawlspace.
- Look for gaps around plumbing vents, electrical wiring, and chimneys in your attic.
- Use expanding foam or caulk to seal small holes, and install covers or gaskets where needed.
- In crawlspaces, sealing gaps between the foundation and framing can stop cold air from entering your floors.
Add or upgrade insulation.
If you want to level up, consider adding or upgrading your insulation. In the South, many homes are under-insulated — especially in older houses. If the floor joists are exposed in your attic, for example, that’s a strong indication that you need additional insulation. Fortunately, rebates are available. Here are key areas to consider:
- Attic insulation: Consider blown-in cellulose or fiberglass batt insulation to reach the recommended R-values for your region.
- Crawlspace insulation: Insulating the floor above the crawlspace can help maintain warmth on the first floor.
- Wall insulation: Harder to retrofit, but sometimes possible with dense-pack cellulose or foam injection.
You don’t always need a full insulation overhaul. Even topping off attic insulation or insulating around rim joists can make a big difference.
Not sure where to start? We’re here to help.
With the right support and incentives, making your home more efficient doesn’t have to be complicated. Start by exploring rebates available for insulation, air sealing, heat pumps, mini splits, and other energy upgrades.

Heating your home and keeping clean air flowing.
6. Sign up for Smart Thermostat Rewards
ENERGY STAR® and the U.S. Department of Energy report that you can save an average of 8%-10% on your heating and cooling costs using a smart thermostat. Find out if your local power company is participating in Smart Thermostat Reward and you can save even more!
7. 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!
8. 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.
9. 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.
10. 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.
11. 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.
12. 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 energy in the kitchen.
13. 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.
14. 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. (Tip: If you forgo the pre-rise, you may need to clean out your dishwasher’s filter a little more often. Consider setting a reminder to clean the filter once a month.)
15. 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.
16. 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.
17. 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.
18. 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.
19. 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 energy on technology
20. 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.
21. 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.
22. 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 energy on laundry
23. 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.
24. 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.
Two for the road.
25. 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.
26. 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 26 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!
How to beat the heat this summer: Smart energy-saving tips for your business.
When the temperatures rise, so can your energy bills — but they don’t have to. With a few smart upgrades and efficiency moves, your business can stay cool without overheating your budget. Here are some energy-saving tips to reduce business energy use.
1. Tune up your HVAC system.
Your HVAC system works harder in the summer, which means small issues can turn into big energy drains. Schedule a seasonal inspection to check refrigerant levels, clean coils and replace filters. It’s one of the easiest ways to boost performance and cut unnecessary costs. Or check out our HVAC incentives, which can help you replace aging units while improving comfort and efficiency year-round.
2. Upgrade to smart thermostats.
Smart or programmable thermostats help you avoid cooling empty spaces. Set temperature schedules based on work hours and occupancy zones to ensure you’re only using energy when and where you need it.
3. Switch to energy efficient lighting.
Still using outdated bulbs? LED lighting uses up to 75% less energy and generates less heat than traditional lighting. That means your cooling system doesn’t have to work as hard either — a win-win in the summer months.
Check out our LED lighting incentives to learn more.
4. Take advantage of TVA EnergyRight® incentives.
From high-efficiency HVAC systems to lighting retrofits, TVA EnergyRight offers incentives to help businesses make smart upgrades.
5. Seal air leaks and improve insulation.
Warm air creeping in and cool air leaking out can quietly drive up your summer energy bills. Inspect doors, windows and ductwork for leaks and add weather stripping or insulation where needed. Sealing up your space keeps cool air in, hot air out and your HVAC system from working overtime.

Energy efficiency for business: the overlooked growth strategy you can’t afford to ignore.
When you think about growing your business, energy efficiency probably isn’t the first thing that comes to mind. But what if it should be?
Whether you’re running a boutique, a print shop, a restaurant or a commercial office space — every dollar counts. Energy efficiency isn’t just about cutting costs. It’s a smart strategy that frees up resources, improves your space and sets your business up for long-term success. Here’s how thinking differently about your energy use could fuel your next big move.
1. Every dollar saved is a dollar to reinvest.
Let’s start with the obvious: trimming energy waste cuts costs. But the real opportunity is what you can do with those savings.
Lower utility bills mean more budget flexibility to reinvest in things that drive growth, like marketing, staffing, equipment, or expanding your product line. And thanks to TVA EnergyRight®, those upgrades don’t have to wait. With cash incentives for things like LED lighting and HVAC improvements, your payback period gets even shorter.
For example, a retail shop that replaces outdated lighting with LEDs could reduce energy use by up to 75%. Combine that with TVA incentives, and those savings could help cover a new POS system, signage or digital advertising campaign.
Explore TVA lighting and HVAC incentives.

2. Energy efficiency for business builds resilience.
The past few years have shown how quickly things can change—utility costs rise, supply chains strain and margins shrink.
Recent data from the report, “From Insight to Implementation: Business Perspectives on Energy Efficiency Investments,” shows that energy accounts for up to 24% of annual operating costs for many businesses, and the percentage is continuing to climb.
Businesses that run more efficiently are better positioned to weather those storms. Reducing your energy consumption now can help you maintain stability, even when operating costs or external factors become unpredictable. It’s one more way to future-proof your business.

3. Customers care about sustainability.
Being energy-conscious isn’t just good for your bottom line—it’s good for your brand.
Today’s consumers are paying attention to how businesses operate. Whether you’re serving a socially conscious Gen Z audience or local clients who care about community impact, small shifts in sustainability, like switching to efficient lighting or optimizing HVAC, can set you apart.
You don’t have to be a certified green business to make a difference. Highlighting smart energy moves on your website or signage helps show customers that you’re thoughtful, forward-thinking and part of the solution.

4. Comfortable spaces boost productivity.
Lighting and HVAC upgrades don’t just cut energy use—they make your space more enjoyable to work and shop in. Bright, natural-looking LEDs can enhance product displays and reduce eye strain. Efficient HVAC systems create more consistent temperatures and improve air quality. These improvements can boost employee productivity and create an atmosphere that encourages people to stay longer and spend more.
Switching to bright, natural-looking LEDs can significantly improve visibility, reduce eye strain, and create a more inviting environment for both customers and employees. According to the U.S. Department of Energy, LED lighting not only consumes up to 75% less energy than traditional bulbs but also improves visual clarity and color rendering — key for retail settings where product presentation matters.A well-functioning, energy-efficient HVAC system helps maintain consistent temperatures, reduces humidity, and improves indoor air quality. Poor indoor air quality is linked to headaches, fatigue, and reduced cognitive performance, which can impact employee productivity.

Powering progress: Five key energy management takeaways from the TVA Industrial Summit 2025
The 2025 TVA Industrial Summit brought together hundreds of energy leaders, facility managers, engineers and sustainability professionals from across the seven-state region to explore the power of industrial energy management, incentives and strategic approaches. Here are five key takeaways you don’t want to miss.
1. Incentives are a game-changer for industrial energy management projects.
TVA EnergyRight’s energy incentive programs are helping turn “maybe someday” projects into fully funded energy upgrades. Case in point: Goodyear received over $845,000 in TVA incentives, cutting more than 11 million kWh in energy use. Incentives don’t just reduce upfront capital costs—they also accelerate payback periods, expand project scope and create competitive advantages by enabling facilities to operate more efficiently than their peers.
Pro tip: Not sure where to start? Incentive upgrades that don’t require pre-approval, such as New Construction LED Lighting and HVAC, are one of the easiest ways to begin.
2. Strategic Energy Management (SEM) is the new business advantage.
Energy isn’t just a line item — it’s a resource you can manage. SEM helps businesses build a culture of continuous improvement by integrating energy-saving practices into everyday operations. Facilities that implement SEM see, on average, a 5-15% energy cost savings, along with better asset utilization, reduced downtime and increased employee engagement.
Case study: A Tennessee-based food processor saved nearly $60,000 by reducing refrigeration discharge, upgrading lighting, fixing compressed air leaks and launching a “Shut It Off” campaign.
3. Demand response = revenue opportunity.
Industrial facilities aren’t just reducing costs—they’re earning credits by participating in TVA’s Demand Response programs. With load growth accelerating, programs like PowerFlex reward facilities for curtailing energy use during peak demand.
Facilities with 5 MW of interruptible load could earn up to $568,200 in annual capacity credits and $48,000 in energy credits*. That’s real money back in your budget.
*Using current pricing for E5+C30 enrollment option. These credits reflect enrollment in 96 hours of capacity per TVA fiscal year. All credits listed are estimates for illustrative purposes only. Actual credit values will vary according to enrollment options selected.
4. Energy assessments make it easy to get started.
If you don’t have a dedicated energy team or you’re unsure where your biggest savings lie, TVA offers free energy assessments to help identify lighting, HVAC, refrigeration, compressed air and process improvement opportunities. The best part? TVA’s Preferred Partners Network can handle the work, from installation to incentive applications.
“The TVA incentive program provides us the opportunity to reduce our overall energy costs and identify future opportunities to control consumption.”
-Pat Jodon, Goodyear Plant Manager
5. Partnerships drive long-term success.
Whether you’re working with a TVA EnergyRight Energy Expert or connecting through your local power company, collaboration is at the heart of the industrial energy efficiency transformation. Events like the TVA Industrial Summit give leaders space to share strategies, troubleshoot challenges, and build partnerships that lead to real results.
Facilities that have completed SEM initiatives report millions in kWh savings and hundreds of thousands in energy cost reductions. One [state-based] furniture manufacturer saved over $600,000 by identifying air leaks, installing a capacitor bank, upgrading to LED lighting and replacing CO2 lasers.

Will a smart thermostat save money?
Inquiring minds want to know! Will a smart thermostat save money? Can you really trim your energy bill with a smart thermostat?
Absolutely. And we did the data digging, so you don’t have to.
How will a smart thermostats save money? Let’s find out!
They learn how to reduce energy waste for you.
Wifi-connected smart thermostats use machine learning to understand when you’re home and what temperatures you prefer. Over time, they create a custom heating and cooling schedule that minimizes energy use when you don’t need it, making them far easier to use than a conventional programmable thermostat.
ENERGY STAR and the U.S. Department of Energy report that you can save an average of 8%-10% on your heating and cooling costs using a smart thermostat.
Translation: If your average energy bill is $150 each month, you could save $140-$150 in just one year. This savings would more than cover the cost of many smart thermostats on the market.
Programs like Smart Thermostat Rewards, offered by TVA EnergyRight and participating local power companies, can help you save even more.
Remote access prevents unnecessary heating and cooling.
Never say “Whoops! I did it again. I forgot to turn the air conditioning off.” Although a smart thermostat will learn your routines, you can still mix things up and adjust your settings anytime, anywhere using an app on your smartphone.
This kind of control prevents unnecessary energy use and even gives you the power to pre-condition (pre-cool or preheat) your home before you walk through the door. We call that a convenience and efficiency double-play.
Geofencing and motion sensors optimize efficiency and comfort.
If accessing an app sounds like too much work, rest easy: many smart thermostats use geofencing (based on your phone’s proximity to home) to detect when you’re away and when you’re on your way home and automatically adjust temperature settings for you.
Some also use motion sensors to determine which rooms are in use, prioritizing comfort in the spaces you’re occupying. This zoned comfort approach helps cut back on energy used to heat or cool unused areas of your home.
Make informed choices with the help of energy reports and usage insights.
Smart thermostats generate monthly energy reports that show how much energy you’ve used, how long your system ran each day, and how your energy use compares to other users. These reports may also offer suggestions for improvement.

With a smart thermostat, comfort and convenience go together like biscuits and gravy.
It’s not just about cutting costs — smart thermostats also improve your home’s comfort and they’re easier to use than conventional programmable thermostats.
Personalized comfort
By learning your schedule and preferences, smart thermostats keep your home at the perfect temperature when you’re there—and scale back when you’re not. You don’t have to keep adjusting the thermostat throughout the day or deal with temperature swings.
Voice control and smart integration
Most smart thermostats are compatible with voice assistants like Amazon Alexa, Google Assistant, or Apple Siri. That means you can change the temperature without lifting a finger.
They may also integrate with other smart home devices, like lights or security systems, for a seamless, connected experience.
How much do smart thermostats cost?
The cost of a smart thermostat generally ranges from $100 to $300, depending on the features and brand. Some utility companies offer rebates or incentives for installing ENERGY STAR® certified smart thermostats, which can lower the upfront cost considerably.
You can shop for and compare smart thermostats on the EnergyRight Marketplace. If you’re thinking about joining Smart Thermostat Rewards (and your local power company is participating in the program), and you have questions about the program, you can find the answers here.
Are smart thermostats worth it?
Note: Features may vary depending on the make and model of your thermostat. Not all local power companies participate in the TVA EnergyRight Smart Thermostat Rewards program.
Smart thermostats offer a powerful combination of energy savings, personalized comfort and modern convenience. With the ability to reduce heating and cooling costs by 10% or more, they’re a smart upgrade for anyone looking to lower their energy bills without sacrificing comfort.
Will a smart thermostat save money? Our research points to “YES.” Whether you’re tech-savvy or just looking for a set-it-and-forget-it solution, a smart thermostat can be a key player in your home’s energy efficiency strategy.
5 fun experiments to teach your kids about thermal energy.
Tired of the chorus of “I’m booooored,” radiating from your kids’ quarters? Build a solar updraft tower, conduct a cooler contest, bake ice cream, create an endothermic reaction, or make a thermometer. These five fun, safe and inexpensive experiments should keep everyone (supervision is always a good idea) productively occupied — for the afternoon, at least.
Build a solar updraft tower.
At full scale, solar updraft towers generate electricity by harnessing the sun’s power. They consist of a central stem that’s surrounded by a greenhouse-like structure. The warmed air rises through the stem, or core, and spins power-generating turbines.
Our version applies the same principles but at table-top scale.
Gather your scientific equipment:
- Black construction paper (about 20 x 20 inches)
- Smaller piece of construction paper (any color)
- Pencil
- Scissors
- Tape
- Piece of modeling clay, formed into a ball
- Wooden skewer
- Plastic needle or toothpick
- Instant read thermometer
- Lamp with incandescent light bulb or heat lamp
- Paper
- Optional: sunshine, and a wind-protected area outside
- Optional: timer
- Optional: white construction paper
Let’s get started:
- Roll your black construction paper into a tapered cone, with a 2” opening at the top, and a 4” opening at the bottom.
- Cut three more-or-less equally distanced, equally sized (approximately 2” long by half an inch tall) arches out of the bottom of your cone. These are your air inlets.
- Use this template to cut a 3” propeller out of construction paper. Bend your “blades” to a 45-degree downward angle.
- Carefully tape a plastic needle or toothpick to a wooden skewer with the pointy end facing upwards.
- Stick the base of the needle-topped skewer into the clay ball and center the black cone over the clay ball.
- Place the propeller on top of the needle. It should be balanced and able to turn freely, like a ceiling fan.
- Record the air temperature inside your tower.
- Now, place a utility lamp with an incandescent light bulb (incandescent bulbs use more energy and generate more heat; that’s why you should use LED bulbs for your home’s lighting fixtures) or a heat lamp at the base of the tower.
- After five minutes, record the air temperature inside your tower and observe what’s happening!

Conduct a cooler contest.
Ever wondered how coozies keep your cola cold? Mystery solved! For an added dash of sibling rivalry, make two coolers and see which one is the coolest.
Gather your scientific equipment:
- 2-4 equally sized, large plastic food storage containers (one will need a tight-fitting lid).
- 2-4 small plastic food storage containers (they will need to fit comfortably, with room to spare, inside the large containers.
- Similarly sized ice cubes.
- Insulating materials such as cotton balls, bubble wrap, or craft feathers (you’ll need enough to mostly fill your large containers.
Let’s get started:
- Identify a flat, sunny outdoor surface — like a picnic table or sidewalk.
- Fill one of the large plastic containers with one of your insulating materials. This is your “cooler.”
- Place the smaller container in the middle of the larger containers and place an ice cube in each of the smaller containers.
- Quickly put the lid on top of your cooler container.
Which ice cube do you think will last the longest? If you made two coolers with different insulation, which cooler do you think will keep the ice cube cool the longest? How do you think your cooler’s insulation is like the insulation in your home?

Let’s get started:
- Preheat your oven to 400° F
- Cut the top half of your cupcakes off and place the bottom half on a parchment-lined baking sheet. (Gee, whatever will you do with the tops?)
- Separate the three eggs. (TIP: Have your lab partner crack an egg into your hand and then gently move the yolk from one hand to the other. Let the whites drip into your experiment bowl and put the yolk in a different bowl.)
- Using a whisk or electric mixer, mix the egg whites with ¼ teaspoon cream of tartar, ¼ teaspoon salt, and ½ teaspoon vanilla. Continue mixing until the whites begin to sitffen and can form peaks. This may take a while, but don’t give up, it’s super cool!
- After your meringue (your flavored egg whites) has taken shape, slowly and gradually stir 1 cup of superfine sugar into your meringue.
- Quickly add a small scoop of ice cream to each cupcake half. Be sure the ice cream does not touch the edges of the cupcake.
- Quickly coat each cupcake/ice cream combo with the meringue foam. Make sure the meringue covers the cake and ice cream completely!
- Place the baking sheet on the bottom rack of the oven and set the timer for 10 minutes. Turn the oven light on and check every three minutes to make sure that the meringue is not burning or browning too quickly.

What is a mini split heat pump and how does it work?
If you’re researching energy-efficient ways to heat and cool your home, you may have stumbled upon something called a mini split. So, what is a mini split heat pump and how does it work? How is it different from a traditional furnace, radiator heat or heat pumps? Let’s dig in.
Industry experts may also refer to these energy-saving, two-in-one heating and cooling units as ductless heat pumps or ductless mini splits. (Looking for more information about conventional heat pumps, AKA dual fuel heat pumps and air source heat pumps, check out this article.)
We know it’s known by many names but what exactly is a mini split, and how does it work? Let’s find out! This article covers everything you need to know — from how mini split systems operate to why they’re a smart choice for homeowners looking to save energy, lower energy costs and increase comfort.

What is a mini split heat pump?
A mini split heat pump is a fully electric heating, ventilation and air conditioning (HVAC) system that provides both heating and cooling. Unlike traditional central HVAC systems that rely on ductwork to distribute air throughout your home, ductless mini splits consist of two main components: an indoor air-handling unit (AKA the head unit) and an outdoor compressor/condenser combo.
These units are connected by a small conduit that houses the power cable, refrigerant tubing, suction tubing and a condensate drain.
Because they don’t require ducts, mini split heat pumps are often used in homes or buildings where installing or extending ductwork would be difficult or expensive — such as older homes, homes without existing ductwork, home additions, garages, detached accessory dwelling units (DADUs) or finished basements.
How does a mini split heat pump work?
A mini split heat pump uses the same basic technology as your refrigerator or traditional air conditioner; however, instead of generating hot or cool air, it transfers heat into or out of your home.
In the summer, refrigerant extracts heat from inside your home (expansion) and pumps it outside, where the heat is squeezed out (compression). In the winter, the compressor works as an evaporator, and the cycle is reversed.
Mini split cooling mode:
- The indoor unit absorbs and extracts heat from the air inside your room using a refrigerant-filled coil.
- The refrigerant carries — or pumps — the heat outside to the outdoor unit.
- The outdoor unit squeezes the heat out of the refrigerant and releases it into the outside air.
- Cool air is blown back into your room.
Mini split heating mode:
- The process is reversed.
- The outdoor unit pulls heat from the outside air — even in cold temperatures.
- The refrigerant carries this heat inside.
- The indoor unit pumps warm air into your space.
Thanks to this heat transfer process, mini split heat pumps are highly energy efficient, using 60%-70% less energy to heat your home than a traditional heating system like an electric furnace or radiator.
What are the benefits of a mini split heat pump?
1. They’re energy efficient.
Because mini splits don’t lose energy through ducts (which can account for up to 30% of energy use in traditional systems), they’re often more efficient than ducted HVAC systems. Many models are also ENERGY STAR®-certified and use inverter technology to adjust power use based on the current heating or cooling need.
2. You have more control over temperature zones in your home.
Mini splits give you the power to control the temperature in individual rooms or “zones.” Each indoor unit operates independently, so you can heat one room while cooling another, or turn off units in rooms that aren’t being used.
3. They’re (relatively) easy to install.
Without the need for ducts, mini split systems can be installed by qualified professionals in a variety of places. Wall-mounted units are the most common head unit, but there are also ceiling-recessed and floor-mounted models available.
Looking for a trusted HVAC contractor? Hire a contractor with confidence when you work with a TVA-vetted member of the Quality Contractor Network (QCN).
4. They’re quiet.
Mini split systems are praised for their quiet performance. The noisy compressor stays outside, and the indoor units are designed to operate with minimal sound, making them great for bedrooms, offices or media rooms.
5. They can help lower your energy bill.
While the upfront cost of a mini split system may be higher than a traditional window unit or space heater, the long-term savings in energy costs can be significant, especially if you’re replacing outdated, inefficient systems.
ENERGY STAR notes that “a typical household’s energy bill is around $1,900 annually, and almost half of that goes to heating and cooling.” ENERGY STAR-certified heat pumps are independently verified to save you energy and money, plus they use up to 60% less energy than standard home electric radiators.
How many indoor head units do you need?
One outdoor mini split unit can typically support up to four or five indoor air handlers, depending on the capacity of the system. The number of units you’ll need depends on the size of your home and how many zones you want to control individually.
Other sizing factors include your home’s ceiling height, number of occupants, doors and windows, and how well (or poorly) your home is insulated. (Need an insulation upgrade? Insulation and air sealing rebates are available.)
Your TVA-vetted QCN contractor can help determine the correct size and number of head units for your space using a load calculation based on square footage, insulation, window size and other factors.
What are the disadvantages of mini splits?
While there are a lot of benefits to installing a mini split, there are a few potential downsides to consider:
- Initial Cost: Installation can be more expensive than a window unit or baseboard heater.
- Aesthetics: Some homeowners don’t love the look of wall-mounted indoor units.
- Maintenance: Filters need regular cleaning and professional service is recommended annually.
Is a mini-split right for you?
If you’re looking for an energy efficient, flexible and powerful way to heat and cool your home, a mini split heat pump could be a smart choice. They’re especially well-suited for homes without ductwork, spaces with specific comfort needs and smaller homes.
