Proven strategies for building performance, budget control and resilience in commercial environments.

Commercial energy efficiency is often framed as a daunting, high-stakes challenge. Rest assured, your energy goals are attainable. The key is to start with what you can control, lean into collaboration and let quick wins fuel your long-term strategy.

In a recent panel discussion hosted by TVA EnergyRight, energy leaders offered an objective and actionable perspective on commercial energy efficiency. Featuring voices from General Mills, Metro Nashville, Middle Tennessee Electric (MTE), and Nashville Electric Service (NES), the discussion offered practical steps organizations of all sizes in both the private and public sectors can take. Here are five standout strategies — rooted in both experience and impact. 


1. Prioritize utility and government collaboration.

Work with your local power company and city team, not around them.

When working in sectors such as large industrial facilities, municipalities, hospitals or universities, efficiency goals are often developed in isolation — only to run into roadblocks related to permitting, infrastructure or communication. But when utilities and city agencies are brought in early, those barriers can become opportunities.

Public-private partnerships can accelerate impact, and transparent conversations can help clarify shared goals and smooth the path forward. For example, public-sector entities like Metro Nashville are aligning energy planning efforts across more than a dozen departments by coordinating data and infrastructure planning — proving the value of early relationship-building for shared success.

“We’re often working across a very diverse set of departments, and we’re trying to create a centralized way of thinking about energy use and performance,” explains Kendra Abkowitz, Senior Director of Sustainability and Resilience, Office of Mayor Freddie O’Connell, Metro Nashville.

Utility-customer collaboration is one of the strongest predictors of success in commercial energy efficiency programs, particularly when supported by effective data sharing and technical guidance. According to Fulcrum, partnerships that unite the strengths of different sectors around shared energy goals tend to deliver better outcomes. That’s why electric utilities often team up with local governments, technology providers and community organizations to expand energy capacity and embed smarter energy management practices across operations.

2. Focus on community partnerships.

Broaden your network to broaden your impact.

Think beyond facility systems and consider where your community is already laying the groundwork for success. Partnering with local energy providers or city agencies can unlock funding, enhance resilience and help large energy users — like industrial facilities, municipalities, hospitals and commercial campuses — better serve their operations and communities. Tapping into these partnerships can unlock access to tax credits, grants and TVA programs. More importantly, it’s an opportunity to build trust and deliver a broader impact.

Public sector partnership in action: Powering Metro Nashville’s efficiency goals. 

One standout example of partnership in action is the 160 megawatt (MW) solar project developed through TVA’s Flexibility program. This unique initiative allows participating local power companies to generate up to 5% of their energy load through locally sourced, cleaner energy.

In this case, Nashville Electric Service (NES) teamed up with Metro Nashville and Silicon Ranch to develop a utility-scale solar array that directly supports Metro’s ambitious sustainability goals — providing clean, renewable energy to power key municipal facilities, reduce carbon emissions and stabilize long-term energy costs.

This collaboration didn’t just result in new solar infrastructure. It demonstrated what’s possible when utilities and public sector organizations align their goals, share the planning process and leverage the financial and technical support available through TVA’s regional programs.

Industrial collaboration: General Mills’ waste-to-energy solution.

Private-sector businesses like General Mills are also embracing collaborative, circular solutions by working hand-in-hand with local utilities and city leaders. At their Murfreesboro, Tennessee, facility — home to the production of all Pillsbury Toaster Strudels and about half the nation’s Yoplait yogurt — they partnered with Middle Tennessee Electric (MTE) and leveraged federal green energy incentives to turn yogurt waste into usable power. 

Together, they leveraged federal rebates to turn yogurt waste into energy, installing a 1.6 MW generator powered by methane from their on-site anaerobic digester. The project not only reduced emissions and operational costs but also improved site resilience, all of which was made possible by proactive support from the local power company. 

Daren Kaiser, Global Energy Strategy Leader for General Mills, says, “We got 40% of that cost covered by a federal rebate, but the real win was Middle Tennessee Electric’s willingness to partner with us. MTE was with us every step of the way. They probably worked harder than our contractors to make sure it came together. That kind of partnership makes innovation possible.”

This type of solution — where waste becomes fuel and utilities help enable, rather than hinder, the process — demonstrates how circular systems can thrive through a shared vision and effective execution.

3. Engage communities and employees.

Efficiency starts with people, not just systems.

Many organizations focus on systems, sensors and technology while overlooking the people who use them. However, both the City of Nashville and corporate leaders on the panel emphasized the importance of engagement in building trust and long-term buy-in.

Metro Nashville gives public tours of solar installations and dashboards to make performance visible and celebrate wins. Internally, companies like General Mills are establishing “green teams” across departments and empowering employees to participate in efficiency planning. And in large systems like hospitals, facility directors and energy teams can use similar tactics — engaging both staff and the surrounding community through energy awareness campaigns as well as training and incentives for employees to identify efficiency opportunities.

Innovative energy projects can sometimes spark internal pushback, especially when other departments are facing budget constraints. Employees may question why specific initiatives move forward while their priorities are put on hold. That’s why transparency and communication are key. 

Brent Baker, EVP and Chief Operations and Innovation Officer for Nashville Electric Service, notes, “When budgets are tight, people notice where the money goes. Even if it’s a different bucket, you still have to explain why one project moves forward over another. That’s real.”

Graphic element: "When budgets are tight, people notice where the money goes. Even if it's a different bucket, you still have to explain why one project moves forward over another. That's real." -- Bret Baker, EVP and CO and IO NES

Don’t underestimate the power of storytelling. Sharing before-and-after data or involving staff in pilot projects can drive broader adoption and boost your bottom line.

When it comes to employee engagement, nearly 74% of employees report that their jobs are more fulfilling when they have the opportunity to positively impact social and environmental issues. And companies with a highly engaged workforce are 21% more profitable and 17% more productive.

Whether it’s showcasing real-time dashboards, giving public tours or celebrating internal wins, making energy progress visible helps build trust and enthusiasm. The more employees and community members understand the impact of efficiency efforts, the more likely they are to support and sustain them.

4. Start with quick wins and build momentum.

Progress beats perfection.

Instead of getting stuck on your biggest energy challenge, start with what’s doable. Whether it’s lighting upgrades, HVAC optimization or low-barrier process improvements, small steps build trust, deliver results and recruit allies. 

Kendra Abkowitz recommends identifying low-conflict opportunities — even if they don’t move the emissions needle right away. 

She says, “Find your quick wins, so you can build momentum, but work where you have that runway and not too many barriers, even if it doesn’t always seem like the most impactful area. This can help gain allies for the work who can be helpful as you move into more challenging areas.”

These smaller successes are more than morale boosters — they can lay the groundwork for long-term change. According to the U.S. Department of Energy, low-cost or no-cost improvements, like LED lighting or thermostat adjustments, can reduce energy use by up to 20% in commercial buildings. That’s not just savings — it’s proof that efficiency works.

Cross-functional teams can accelerate this process. Brent Baker of NES recommends pairing skeptics with champions. “The light bulb moments happen when cross-functional teams come together — when someone who’s not sure gets to see the benefit firsthand,” says Baker.

5. Scale smart: invest for resilience and carbon reduction.

Pair your momentum with long-term investment.

Once you’ve captured early wins and built internal support, the next step is to take on transformational projects that deliver lasting cost savings, operational resilience and regulatory compliance — ideally with strong utility partnerships and a clear strategy for financing and implementation.

These investments may include:

  • On-site solar and battery storage.
  • Waste-to-energy systems such as anaerobic digesters or combined heat and power (CHP) units.
  • Fleet electrification or replacing fossil-fueled equipment with electric alternatives.

Energy-intensive facilities, including manufacturing plants, universities and hospitals, can benefit from these investments, not only to reduce emissions but also to ensure energy reliability for critical systems. For example, some healthcare facilities have already implemented combined heat and power (CHP) units to enhance energy efficiency while providing a resilient backup power source for operating rooms, ICUs and labs in the event of an outage.

While the up-front costs for these technologies can be higher, aligning with utility programs and incentive structures can dramatically improve ROI. TVA’s EnergyRight incentives, for example, have helped companies across the region accelerate their transition while staying competitive. Early coordination with your local power company can also help smooth interconnections, identify potential grid limitations and ensure operational reliability.

Investing in Carbon-Free Technologies.

At General Mills, a combination of clean energy strategies has helped them reach net-zero emissions for Scope 2 electricity use, thanks to a mix of RECs and renewable power purchase agreements. To reduce Scope 1 emissions — which are typically harder to address — they’ve implemented waste-to-energy systems at several sites, including a 1.6 MW CHP unit fueled by methane from yogurt waste at their Murfreesboro plant.

Graphic element: What's the difference between Scope 1 and Scope 2 emissions?

Think of Scope 1 as “on-site” emissions and Scope 2 as “purchased energy” emissions.

Why it matters.

According to the International Energy Agency, clean electricity and electrification will account for more than 50% of global CO₂ reductions needed to reach net zero by 2050. Businesses that adopt low-carbon technologies now are better positioned to address regulatory shifts, meet customer expectations and ensure future energy resilience.

It’s not just about checking a sustainability box. It’s about improving reliability, controlling costs and preparing for long-term success.

The bottom line? Balance.

From morale and momentum to grid resilience to cost savings to decarbonization, the path forward isn’t one-size-fits-all, but it is a walkable one. As panelist Robert White of MTE explained, “This next generation of customers, they’re pushing, and they don’t want to hear excuses. They want to hear commitments — at the same time, we’re trying to find that balance between reliability and affordability. We want to be part of the solution.”

We want to be part of the solution." Robert White, VP of community relations, MTE

Meeting energy goals in both private and public commercial sectors requires balancing performance, cost and care delivery — without compromising on reliability. As TVA’s VP, Environment and Stewardship, Michael McCall explains, “There’s no free lunch. Every energy source has trade-offs. The real goal is to stay committed, work together and keep showing up.”

Power moves: How innovative facilities turn their utility into a strategic growth partner. 

Business & Industry

Stop thinking of your local power company as just another bill to pay. Start thinking of them as one of your competitive advantages.


Rethink what your utility can do for you.

In today’s high-stakes operational environment, energy is more than a line item — it’s a strategic lever. But most facilities treat their local power company (LPC) as a background vendor.

What if, instead, you treated them like a growth partner?

Stop overlooking your most powerful business ally. From infrastructure planning to incentive stacking, your LPC can help you cut costs, boost performance and future-proof your operations. And yes — sustainability often comes baked in.

Step 1: Bring them in early, before growth becomes a challenge.

If you’re scaling, shifting or modernizing operations, your energy needs are changing — fast.

The smartest move? Loop in your LPC before you break ground or expand your process lines.

LPCs like Middle Tennessee Electric (MTE) have helped major industrials like General Mills avoid costly redesigns and power bottlenecks by modeling future load growth, flagging infrastructure gaps and helping shape more innovative expansion plans from the start.

Robert White, VP of Community Relations & Member Services for MTE, explains, “We helped General Mills integrate a 1.6 MW anaerobic digester. We were at the table from the beginning, and that helped them avoid obstacles later.”

Graphic element: "The #1 barrier? Budget, not willpower. 43% cite capital as the top obstacle to efficiency upgrades.

Step 2: Tap into incentives you didn’t know you had.

Efficiency upgrades can deliver fast ROI, and in the Tennessee Valley Region, LPCs in partnership with TVA EnergyRight are willing to help you pay for them. The trouble is, too many businesses leave those dollars on the table.

From lighting and HVAC to refrigeration and advanced building controls, your LPC may offer:

  • Rebates that reduce capital expenditures.
  • Demand response payments to reduce peak load costs.
  • Shared-risk pilot programs for new technologies.

Source: EnergyRight.com

Step 3: Use utility data to benchmark, optimize and scale.

Your LPC has visibility across sectors, regions, and use profiles. That means they know what “good” looks like — and where your facility may be falling short.

“We can bring benchmarking data to the table. That’s the power of working with an LPC that knows the territory,” says Brent Baker, EVP and Chief Operations and Innovation Officer, NES.

By sharing load data and operational goals, you can uncover:

  • Inefficiencies you didn’t know existed.
  • Time-of-use strategies to reduce spend.
  • Long-term energy models that align with your growth targets.
Graphic element: Energy costs are squeezing your margins. 58% of businesses say rising energy costs threaten profitability.

Step 4: Reduce the risk for big ideas with a technical ally.

Innovation always carries risk — but your LPC can help you sell it to your team and manage it.

Whether you’re exploring on-site generation, EV fleet planning or battery storage, utilities can support you with:

  • Interconnection guidance.
  • Reliability modeling.
  • Regulatory navigation and incentive layering.


General Mills has achieved net-zero Scope 2 emissions globally. With help from MTE, they integrated a 1.6 MW generator powered by yogurt waste — an anaerobic digester that cut emissions and costs while increasing energy independence.

Graphic element: Businesses aren't waiting. They're acting. 61% have already invested inefficiency, and 30% more plan to.

Step 5: Make energy efficiency your competitive advantage.

Sustainability might sound like a buzzword — but in practice, it’s often the byproduct of smart, forward-thinking business decisions. And energy efficiency? It’s not just about cutting costs. It’s about building resilience, boosting productivity, and unlocking long-term value.

When you partner with your LPC to optimize systems or reduce reliance on fossil fuels, you’re not just reducing overhead, you’re:

  • Strengthening your operational reliability.
  • Improving safety and performance metrics.
  • Reinforcing your long-term competitiveness.


Whether you run a manufacturing plant or a university campus, every efficiency upgrade is an investment in your facility’s ability to scale, adapt and thrive.

Final thought: Loop them in early. Lean on them often.

Before you call your engineer, contractor or architect, call your local power company.

They’re already invested in your success. And when you treat them like a strategic partner, not just a service provider, the benefits ripple across your operations — from budget to resilience to bottom line.

Calling all junior detectives! Use your sleuthing skills to spot sneaky leaks.

Residential

Is it a GHOST or a drafty window? Did a BLACK CAT just cross your path, or is there a breeze sneaking in under a door? Is your bedroom HAUNTED, because it’s always chilly — even when the heat’s on? If any of this sounds familiar, there may be energy mysteries in your home — and YOU can help solve them.

Graphic element showing a lightning bold, magnifying glass and flashlight.

Here’s what you’ll need in your energy sleuth’s detective kit:

  • Post-it notes (Write: “BOO! An energy ghost lives here!” on at least 12 of them) 
  • Craft feathers (the feathery the better!)
  • Flashlight
  • Thermometer (optional, for comparing room temps)

Ready for your first mission? Grab your energy sleuth’s detective kit and your grown-up because we’re going on a home energy ghost hunt.

Mystery #1: The ghost in the window.

Windows let you keep a friendly eye on the world outside, but sometimes they let in more than you’re bargaining for.

DETECTION: On a windy day — the windier the better! — grab the lightest feather from your kit. Very slowly move the feather around the edges of every window in your house. It’ll help you detect unwanted airflow around window frames, doors, baseboards, electrical outlets, crawlspaces, registers, and attic doors. 

When your feather is “tickled” you’ve found a draft ghost! Sound the alarm (we recommend a ghoulish howl) and mark it with a BOO note. 
Fresh out of feathers? Run your hand under cold water and you’ll be able to feel the ghostly drafts for yourself! 

SOLUTION: For a low-cost fix, your grown-up partner can use clear weatherstripping or a window insulation kit to seal the gaps and keep warm air inside. For more hot tips on air sealing and insulation, be sure to check out this article!

Mystery #2: The case of the chilly door.

DETECTION: Make a list of all the doors in your home — front door, back door, sliding door, side door. Do any of them feel colder near the bottom? Can you see light coming in around the edges? Take a piece of paper and close it in the door. Then, try pulling it out. If it slides out easily, air is probably slipping through there, too!

SOLUTION: Add a door sweep or a rolled-up towel to block the draft. Feeling crafty? You can make and decorate your own “draft snake.”

Mystery #3: The clue of the cold floor.

DETECTION: On a chilly day, take your socks off — if you dare! — and walk around your home. Pay extra close attention to areas where your toes feel chilly. If you feel a cold spot, mark it with a BOO note. 

SOLUTION: Ask your grown-up if you can help them pick out a few area rugs. You can even grab your flashlight and head down to your basement or crawlspace to look for leaks. Insulation and air sealing can help stop chilly floors.

Mystery #4: The secret of the whistling outlets.

Did you know cold air can sneak in through electrical outlets? Especially on outside-facing walls!

DETECTION: On a windy day, place the palm of your hand gently over light switches or outlets near exterior walls. Feel a tickle of air? That’s a hidden leak! Mark it with a BOO note.

SOLUTION: Encourage your grown-ups to take you on a field trip to your local hardware store to buy outlet gaskets. These inexpensive insulating foam pads go behind outlet covers — they’re easy to install and super helpful.

7 energy efficiency tips for renters.

Residential

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.
Graphic element that reads: Pro Tip: Checking your home for air leaks works best on cool, windy days.

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.

Graphic element that reads: "Ever degree you set your thermostat lower in the winter (or higher in the summer) save about 3% on heating and cooling costs.

If your space has room-specific heaters, close doors and heat only the rooms you use most often.

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.

graphic element promoting air sealing and insulation rebates

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.


  1. Check the forecast and time your test for a windy day — this makes it easier to feel the drafts. 

  2. Turn off combustion appliances such as gas ranges, ovens, furnaces and water heaters. 

  3. Close all your windows, exterior doors, vents, and flues.

  4. 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.

  5. 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:

Woman standing in front of a window, checking for air leaks.

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.

Sometimes the hardest thing about saving energy isn’t the task itself … it’s remembering to do it! For recurring events, like changing your air filter at least once every three months, add them to your calendar and enjoy having one less thing you have to remember.

4. Enroll in TVA’s Green Switch program.

For as little as $2 a month on your electric bill, you can support 100% solar energy sourced directly from the Tennessee Valley. Enroll in Green Switch today.  

5. Set the mood with smart LED bulbs

Level up your LED game this year with smart LED bulbs. You’ll have fun programming your lights to greet you (turn on automatically) when they detect motion, aligning brightness to circadian rhythms, selecting custom colors — and control them all via an app or voice command.

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-rinse, 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.

Business & Industry

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.

Learn more about HVAC incentives.


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.

 Explore available incentives.


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.

Business & Industry

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

Business & Industry

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.

Illustration that reads: "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.

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.
