Home Energy

Home is where the heart is. It’s also where the energy bills are. From month to month, your electricity or natural gas bill can change dramatically, depending on how you’re using energy at home. 

Whether you rent an apartment or own a single-family house, you can improve your experience at home while saving money with a few simple changes. 

Making smart choices about energy use, water conservation, waste, materials, and improvement projects can increase your comfort at home and reduce your out-of-pocket costs, while also benefiting our neighbors and the broader community by reducing energy and lowering greenhouse gas emissions.

On this webpage, you’ll find information, resources and assistance to encourage energy-saving activities and behaviors at home.



The first step to reducing your bills is being aware of how much energy you use, and it’s easier than you think. 

Use the U.S. Environmental Protection Agency (EPA) Carbon Footprint Calculator to estimate your greenhouse gas emissions and learn the numbers behind your personal choices and habits at home. Using basic information about your household size, general location, and home energy costs, the calculator identifies ways to reduce your emissions and provides estimated annual savings. 

How to evaluate your household numbers:

  • Review your utility bills and average energy use (total kWh used) per month
  • Look for major discrepancies from month to month and year to year, and try to reason through what may be causing big swings – is it something behavioral like running your HVAC when you’re not home, or is it something technological/physical like an air leak?

While you’re evaluating your home energy use, you should also look at how other daily activities like driving your car contribute to greenhouse gas emissions – by reviewing your car’s fuel bills, vehicles miles traveled and average mileage.

Ready to take it a step further? A home energy assessment, also known as a home energy audit, lets you know how energy efficient your home is. It identifies problem areas and recommends improvements so you can save energy and money on your utility bills month after month.

During a home energy assessment, a contractor will examine your home for upgrades and repairs that can save you both energy and money. At the conclusion of the assessment, you will be provided with a personalized report with suggested changes and actions to help keep your energy costs down. 

If you choose to act on any of the recommendations, you may qualify for federal tax incentives or one or more rebates from your utility provider.

Federal, state, and energy provider incentives can help Fairfax County residents offset the costs of purchasing and installing energy-efficiency upgrades and equipment. Visit the U.S. Department of Energy’s Energy Savings Hub to learn more about federal incentives for home energy upgrades.

Virginia has its very own energy efficiency education program with information on tax incentives and rebates – Virginia Energy Sense. Additionally, the websites below offer a variety of financial assistance options for home energy projects.


While a home energy assessment by a licensed energy auditor will provide the most comprehensive results, there are many do-it-yourself steps that you can take on your own to improve your home's energy efficiency. The following EPA and U.S. Department of Energy online resources can help you conduct your own energy assessment and identify improvements:


Fairfax County residents can reserve thermal imaging cameras from any branch of the Fairfax County Public Library. Use the camera to inspect your home or business for hot and cold spots, then make energy saving upgrades.



Even small actions, like changing out inefficient lightbulbs or sealing cracks around windows and doors, can make a big impact. If everyone in Fairfax County took these simple steps, we would be on our way to achieving our goals for greenhouse gas reduction. 


If you’re in the market for a new fridge, washing machine, or other major household appliance, look for the ENERGY STAR label to ensure you’re getting the most energy-efficient model. This certification from the EPA indicates that a product is more efficient than its conventional counterparts. 

Investing in ENERGY STAR technology can save you energy and money over time. A new ENERGY STAR refrigerator is about 15 percent more energy efficient than the minimum federal standard for refrigerators and can cost you about $50 a year to run, on average, while a full-size electric ENERGY STAR washer can save more than $350 in energy costs over the lifetime of the product.

Use the ENERGY STAR Rebate Finder to find available rebates and special offers on ENERGY STAR-certified products.

In addition to saving money over time by purchasing energy-efficient appliances and technology, you can also receive rebates from local utilities for your investment. 

If you are a customer of Dominion Energy, you can find available rebates for ENERGY STAR purchases online. You can also take advantage of Dominion’s appliance recycling program and you may be eligible for a $20 rebate when you recycle your old, inefficient refrigerators and freezers. 



One of the simplest ways to avoid paying too much for energy is to adjust your thermostat. If you have a programmable thermostat, use it to establish a schedule in the winter months so that your house is warmer when you’re home and awake and cooler when you’re away or sleeping. The same strategy applies in the summer months: set the temperature as high as is comfortable when you're home and warmer than normal when you're away. Even one or two degrees either way can make a big difference.

If you don’t yet have a programmable thermostat, consider purchasing one. Dominion Energy is currently offering up to $30 in rebates to customers who purchase a smart thermostat and even more savings for those who enroll in its smart thermostat rewards programs. In the interim, set an alarm on your phone or clock to remind you to adjust your thermostat before you leave or when you get home.

Save money just by switching to LEDs, or light-emitting diodes, which are more efficient and longer-lasting than standard incandescent bulbs.
