A bitterly cold winter in many areas of the United States have HVAC systems working overtime. And for those in the Midwest, the U.S. Energy Information Administration (EIA) anticipates rising energy costs between 2% to 11% this winter, as the weather returns to more traditional conditions.
Utilities expect electricity consumption to grow by 4.7% in the next five years, according to The Kiplinger Letter, and that booming demand is running into supply constraints as infrastructure is built to generate more electricity from solar panels and wind turbines.
On the bright side, consumers who heat their homes with natural gas are paying less now than they were a couple of years ago, when Russia’s invasion of Ukraine led to soaring gas prices in Europe that spilled over into U.S. markets. The EIA predicts that futures prices for natural gas will shift upward in 2025; if that happens, households may see modest increases in their gas bills.
Overall, the average utility payment per customer was nearly $300 in March, up by about 23% from five years earlier, according to data from Bank of America. Experts say record-high temperatures, the growing prevalence of wildfires and other natural disasters, and a slow transition to renewable energy are to blame, among other factors.
Whatever the direction of utility prices, it pays to make moves that reduce your energy usage. “You can implement plenty of low-cost strategies right away that will have an impact on your energy bill,” says Ryan Shea, a manager in the carbon-free buildings team at RMI, a nonprofit that aims to reduce global energy consumption. And for those with a sizable budget, making a few bigger-ticket home improvements could slash your energy costs significantly and help you qualify for some handsome tax breaks.
Here are 18 ways to use less energy at home and lower your utility bills. Everyday changes
Shop for better electricity prices. If you live in a state that allows you to choose who supplies your electricity — 13 states and Washington, D.C., do, according to the Retail Energy Supply Association — compare rates to make sure you’re getting the best prices. Some states offer online tools that make it easy to shop around, such as Maryland’s MD Electric Choice and Connecticut’s Energize CT.
See whether your utility provider offers time-of-use pricing. Another way to cut your electricity costs is to take advantage of a dynamic pricing plan, through which a utility supplier charges customers higher or lower rates depending on when they consume electricity.
“If you’re on a time-of-use rate, you can plan your energy consumption around that by doing more energy-intensive tasks, like running your clothes dryer, during off-peak hours to save money,” says Jennifer Amann, a senior fellow in the buildings program at the American Council for an Energy-Efficient Economy. Off-peak hours can vary depending on the time of year and your region.
Note that some states, such as Colorado, have implemented “opt out” programs. In these states, every household is automatically placed in a time-of-use price plan, so you may already be enrolled in one without knowing it. Contact your utility provider to learn more about your plan.
Get a smart thermostat. If you still have a manual thermostat, you may want to upgrade to a smart thermostat, a device that allows you to control the temperature of your home from an app. Because it lets you adjust your thermostat from anywhere, it’s especially handy if, say, you forget to lower the temperature before you leave for a trip during colder months (or you forget to raise the temperature during a summer vacation).

Turning your thermostat down 7 to 10 degrees from its normal setting for eight hours a day in the winter and dialing it up 7 to 10 degrees for eight hours a day in the summer — say, while you’re at work — can cut your home’s heating and cooling costs by as much as 10% a year, according to the Department of Energy.
Keep your HVAC system in tip-top shape. Maximizing your HVAC system’s efficiency can help reduce your home’s heating and cooling costs. Replace the air filters every three months or according to the manufacturer’s instructions. Signing up for an air filter subscription could save you some money.
It’s also a good idea to schedule an annual tune-up with an HVAC technician, who can check for signs of a leak or damage that could be hindering your system’s performance.
Use ceiling fans, vs AC, strategically. “Ceiling fans can make it feel like the temperature in a room is 2 to 3 degrees cooler than it actually is,” says Amann. The labor cost to install a ceiling fan is approximately $250 to $700, according to HomeGuide, a marketplace that connects homeowners with construction and home-maintenance professionals. Ceiling fan prices typically run between $50 and $300.
Make sure to rotate ceiling fans counterclockwise during the summer to allow the blades to push the cooler air down, Amann says; in the winter, blades should move clockwise to distribute warm air around the room. Also, turn off ceiling fans when you leave the room to conserve energy.
Block out sunlight in the summer. Heat gain from sun exposure can drive up your cooling bill, so on summer days you should close draperies or blinds on windows that receive direct sunlight. Consider installing medium-colored draperies with white-plastic backings, which the Department of Energy says can reduce heat gain by 33%, on average. For maximum effectiveness, drapes should be hung as close to windows as possible and fall onto the windowsill or floor.
You could also install film on windowpanes to help block out the sun’s rays. The total cost to place film on a 30-by-60-inch window yourself is just $10, on average, according to the Efficient Window Coverings Collaborative.
Harness natural light in the winter. Keep curtains and blinds open, especially on south-facing windows, to let sunlight naturally heat your home during the cold-weather months.
Plug openings. Air leaks can drive up your utility bill. “Seal up all of the nooks and crannies that are leaking air into and out of your house,” says Joel Rosenberg, a researcher at the nonprofit Rewiring America and author of Electrify Everything in Your Home. Pay close attention to gaps or cracks around air vents, windows and doors. Caulking air leaks throughout your home — an inexpensive DIY project — can trim your energy bill by 10% to 20%, according to the DOE.
Another way to tighten your home’s envelope is to add insulation in the attic, basement and crawl spaces. “Weatherizing a home typically has the biggest cost savings in colder or hotter climates,” says Ryan Shea, of RMI.
Moreover, if you have a wood-burning fireplace, close the chimney flue when it’s not in use; an open chimney provides a clean shot for warm or cool air to escape your home.
Install energy-efficient lighting. If your home still has incandescent light bulbs, replace them with LEDs, says Bahareh van Boekhold, an energy-efficiency policy and program expert and senior managing con-sultant at ILLUME Advising, an energy-industry consulting firm.
“Installing LED lights is a no-brainer, since they provide a great return on investment,” she says. Incandescents consume about 60 watts of electricity, while LED light bulbs use only about 10 watts, on average, according to EnergySage, a com-parison-shopping platform for home solar-energy systems. LED bulbs also last up to 25 times longer, according to the DOE.
Adjust your water heater. Water heating is typically the second-largest home energy expense after space heating and cooling. Some manufacturers set water heaters to 140 degrees — an unnecessarily high temperature. Lowering the temperature to 120 degrees could save you more than $400 a year and reduces the risk of scalding.
Also, “if you have an older water heater that you’re not quite ready to replace, a water heater blanket can help” prevent heat from escaping, says Amann.
Cook efficiently. When it comes to energy consumption, it’s better to use a toaster oven instead of a full-size oven. In fact, cooking a meal in a toaster oven could save over 50% of the energy used to cook the same meal in a conventional electric oven, according to Consumer Guide to Home Energy Savings, a book that Amann coauthored. “If you’re just reheating leftovers, it’s better to do it in a toaster oven, which can heat up faster than a full-size oven,” Amann says.
When you need to cook in a full-size oven, avoid opening and closing it frequently, which can reduce the oven’s efficiency. According to one estimate, the oven temperature can drop 25 degrees when you open the door a single time. Use a kitchen de-greaser to gently clean the seal on your oven door so that the appliance retains the maximum amount of heat.
Wash clothes with cold water. Water heating makes up about 90% of the energy it takes to run a washing machine, the Environmental Protection Agency says, so consider using your washer’s cold-water cycle for most loads; reserve hot water for heavily soiled clothing and linens and towels, as well as white garments that easily show dirt. Cleaning your dryer’s lint filter before each cycle can help your clothes dry more quickly.
Slay energy vampires. According to the Natural Resources Defense Council, nearly one-fourth of home energy use is consumed by “vampires” — devices that suck electricity even when they’re turned off. The average home has 20 to 40 energy vampires — TVs, printers, computers, device chargers, small electric appliances and gaming consoles, to name a few. Using stand-by power is responsible for about 1% of global carbon emissions, according to the Lawrence Berkeley National Laboratory.
Unplugging devices when they’re not in use can reduce your home’s energy usage. If you have a cluster of energy vampires in a specific area, plug them into a timer power strip, which allows you to set a schedule for when they’re turned on and off, reducing their phantom load.

Order an energy audit. Many experts recommend that before you make any home improvements, you should get an energy audit, a whole-house diagnostic assessment by an energy professional that will identify ways you can make your home more efficient.
“An energy audit is a great first step because it can help you create a plan and prioritize what repairs and changes you should make to your home,” says Amann. “Without an energy audit, you’re flying blind in terms of what opportunities you have and what challenges you might encounter when making your home more energy-efficient.” A home energy audit typically costs between $200 and $700, often depending on the size of your home, according to Angi, a home-services website.
“Some energy audits will include a Home Energy Score that grades your home’s energy efficiency between zero and 10, with 10 being the most efficient,” says van Boekhold. “A Home Energy Score is like a mile-per-gallon rating but for your home. With it, you can understand how efficiently your home is running and take steps to make it more efficient.” The score was developed by the U.S. Department of Energy and its laboratories.
See whether your utility company provides a subsidy or rebate for an energy audit, advises Rosenberg. Homeowners may also be eligible for a federal tax credit of 30% of the cost of an energy audit, with a maximum credit of $150 per year (see below for more on tax credits for energy-efficient home improvements).
Get a customized plan with this online tool. Rewiring America recently released a Personal Electrification Planner, which you can use to get an energy-efficiency plan tailored to you based on your home, lifestyle and goals. “It’s very easy to use and provides a lot of valuable, specific information,” Shea says of the tool.
Plug in your home’s address, square footage and a few other details, and the planner will generate a list of home improvements, including cost estimates for each project, as well as the annual energy savings and carbon-emission reductions they’ll provide.
Earn energy tax credits. The Inflation Reduction Act, a sweeping piece of legislation signed in 2022, offers a number of tax credits and deductions for energy-efficient home improvements. The Energy Efficient Home Improvement Credit lets homeowners claim a tax credit for up to 30% of the cost of certain energy-efficient improvements, up to $1,200 per year.
Even more generous: Homeowners can qualify for a yearly credit of 30% of the cost, up to $2,000 per year, for heat-pump water heaters and heat pumps for heating and cooling your home that meet the highest “non-advanced” efficiency tier set by the Consortium for Energy Efficiency (CEE). Go to Save Big By Going Green At Home to learn more about the Inflation Reduction Act tax credits.
Outfit your home with energy-efficient appliances. Over their lifetimes, Energy Star–certified appliances can reduce greenhouse-gas emissions by about 130,000 pounds and save an estimated $11,000 on your home’s energy bills, according to the EPA. You can see whether your utility provider offers rebates for Energy Star appliances. You may also be eligible for a rebate through the Home Electrification & Appliance Rebates program, depending on your income and where you live; for more, see Rewiring America.
Consider solar panels. It costs about $30,000, on average, to purchase and install a 10-kilowatt solar system, according to EnergySage. Fortunately, the Inflation Reduction Act provides homeowners with a 30% tax credit for solar installations until 2032. (The credit drops to 26% for solar systems installed in 2033, falls to 22% for systems installed in 2034 and then expires.)
That means now could be a good time to install solar panels, depending on how long you plan to own your home. For a typical home, it takes about seven to eight years to break even, EnergySage says. Homeowners who install a solar panel system can save anywhere from $28,000 to $120,000 over 25 years.
Wondering whether your home is a good candidate for solar panels? Enter your address into the tool at Google Project Sunroof to see how many hours of usable sunlight your house receives each year, the recommended size of a roof solar installation for your home and the estimated net energy savings over the course of 20 years.
