61 Tips Guaranteed to Lower Your Power Bill

If you’re looking for ways to save money, reducing your average household electric bill is the perfect place to start. Most households have ample potential for energy savings, from 5-minute DIY projects and energy-efficient upgrades to energy-saving habits that are easy to adopt.

Here are the easiest, most effective steps you can take to reduce your electricity bill.

What's a normal electric bill?

Your energy bills are determined by how much energy you use and the cost of electricity where you live. If you live in EPB’s customer territory, your electric rates are about 70% lower than the rest of the United States.

Homes that are around 2,000 square feet can use anywhere from 700 to more than 2,000 kilowatt-hours (kWh) worth of energy, depending on energy efficiency, the time of year and whether you’re paying for a one person electricity bill or for your entire family’s energy usage. With this in mind, a “normal” energy bill for an average-sized home would fall somewhere between $67-$200 or more during the coldest and hottest months.

Why is my electric bill so high?

If you have an average-sized home (around 2,000 square-feet in Chattanooga, Tennessee) and your energy bill is costing you more than $300 a month, it likely means there are opportunities for you to improve your home’s energy efficiency.

The key to lowering your average household electric bill is realizing that nearly every modern convenience is powered by the electricity that you purchase each month — so the more you can eliminate unnecessary energy usage using the tips below, the more you’ll save.

Understanding your power bill

Several factors go into determining your energy bill, including the following:

Your household’s total kWh usage — 1 kWh is equal to the energy it takes to power a 100-watt bulb for 10 hours.

The Fuel Cost — Your fuel cost is determined by the utility that generates your electricity. For EPB customers, energy is generated by TVA and distributed by EPB.

Outdoor temperatures — If you’re wondering, “is heating and cooling included in electric bill” the answer is, “yes.” Your HVAC system is your highest source of energy usage, which means cooling your home during heatwaves, and warming your home during freezing temperatures requires more energy.

Efficient operations — The cost of the labor and equipment used to deliver energy to your home. At EPB, we work hard to keep rates below the national average.

If you need additional help understanding your EPB Energy bill, our EPB Energy ProsSM can help.

As you can see, the part of your bill that is within your control is your household energy usage. There are plenty of ways you can reduce your energy bill without sacrificing convenience or comfort, especially when it comes to improving efficiency and automating energy-saving habits with the steps below.

Is it possible to save on your power bill?

Absolutely! The key is to adopt the mindset that nearly everything you do is powered by electricity that you purchase each month. Many of our daily activities that use the most electricity can start to feel automatic, like heating and cooling our homes, but the truth is, all energy usage “counts” toward your bill.

By making an effort to track your energy usage, you can identify opportunities in your home where you can help your appliances and devices perform the same tasks with less power. The more you can eliminate unnecessary energy usage with these 61 ways to reduce electricity bill, the more you’ll save!

12. Insulating paint

Insulative paint is a new technology that claims to prevent heat loss and transfer. However, research is still being done to determine whether insulative paint is worth the cost. Some studies have already shown that insulative paint does add some amount of insulation, but others say it’s ineffective in preventing heat loss.

13. Wear comfortable clothing

Lowering your electricity bill doesn’t always require changing something about your home. Sometimes, saving energy is as easy as changing your clothes to be more comfortable instead of changing the temperature on your thermostat. If your thermostat is set on 68ºF in the winter, but you’re feeling chilly, throw on some sweatpants, socks and a hoodie to see if it helps. In the summer, wear shorts or loose clothing to stay cool without cranking up the AC.

14. Use more blankets

Another way to save energy during colder months is to stay cozy under the covers. Get soft blankets that feel good against your skin and look beautiful with your decor. A good blanket may be enough to keep you warm without turning up the heat. You can even find energy-efficient electric blankets that can help you stay warm for less.

15. Reduce phantom power

Also known as “vampire energy,” this type of electricity is consumed by appliances when you’re not even using them. This can cause substantial increases to your energy usage and cost you hundreds of dollars per year.

save energy

Common energy vampires are:

● Device chargers (cell phones, laptops, tablets)

● TV set top boxes

● Gaming consoles

● VCR, DVD and DVR players

● Standby coffee makers

● Microwave ovens

● Devices that use a standby mode to turn on instantly

● Computer monitors

● TVs with screensavers

● Anything digital, clock or light that stays on

You can eliminate energy vampires by plugging them into a power strip and switching it off when not in use.

16. Adjust fridge and freezer temperature

According to, the recommended temperature setting for maximum energy savings is 35–38ºF for your fridge and 0ºF for your freezer. Check your appliances’ temperature settings and make adjustments to save energy.

17. Keep your fridge and freezer full

Some sources claim that keeping your fridge and freezer at least ¾ of the way full can help with cooling, since the food acts as an insulator. Other sources claim that this won’t help enough to significantly impact energy costs, but it may be worth a try.

18. Keep refrigerator coils clean

Routine maintenance helps maximize the energy efficiency of your refrigerator. Refrigerator coils can collect lint, dust or pet hair, which causes your fridge to work harder and use up to 35% more energy. Inspect your refrigerator coils every six months to a year. If you have pets who shed a lot, you may need to clean your coils more frequently.

19. Cover food and drinks before placing them in the fridge

Use Tupperware, foil or plastic wrap to cover your food before storing it in the fridge. Uncovered food can release moisture into the air, which makes it work harder to maintain cooler temperatures.

20. Wait for food to cool before putting it in the fridge

If you place hot food directly in the refrigerator, it adds heat, which makes your fridge work harder to cool down.

21. Have a second fridge or freezer? Put it in the basement.

Many families have a second fridge or freezer to store meals, drinks and other food. You can save energy by placing your secondary fridge or freezer in the basement or in a room away from sunlight and heat. This will help it stay cool and consume less energy.

22. Turn off your ice maker

Does your freezer have an automatic ice maker? After your ice bucket is full, turn off the ice maker. This can reduce your freezer’s power consumption by up to 20%. If you don’t use ice very much, you can keep it off permanently for added savings.

23. Turn off your stove

When you’re cooking with your stove, you can save energy by turning it off a few minutes before your food is fully cooked. The stove will typically have some heat left over that can finish the job without demanding more energy.

help conserve energy

24. Keep your oven closed

When checking to see if your food is done, keep the oven closed to prevent heat loss. If you need to look at the food, flip on the internal oven light and look in the window instead. You can also invest in a thermometer with a cord that shows you the temperature of the food while the oven is closed.

25. Use lids when cooking

While your food is cooking, use a lid to trap heat and make your food cook faster. This helps your oven or stove use less energy.

26. Stop preheating your oven

While some recipes call for preheating your oven, others will work just fine if you place your dish inside during the preheating process. Just add a few minutes to the total cooking time, and you’ll save energy without noticing much of a difference.

27. Get more use out of your microwave

It’s true — microwaves consume up to 80% less energy than ovens. And microwaves can do far more than just warm up leftovers. There are countless ways you can use your microwave for cooking, such as steaming vegetables and or baking a molten lava cake in a mug.

37. Air-dry your dishes

Do you have a drying rack? After your dishwasher completes its cleaning cycle, make sure the heat dry setting is turned off and unload your dishes onto a drying rack. That way, it won’t cost any energy to dry your dishes (which means no additional cost on your electricity bill).

38. Use cold water to wash clothes

Wash your clothes with cold water whenever possible (you may need to switch to a “cold water detergent” for effective cleaning). Even just switching the water temperature from hot to warm can cut your washer’s energy usage in half, and certain fabrics last longer when washed with cold water.

39. Start line drying laundry

Dryers consume lots of power and are mostly just used for saving time. They can also warp or shrink certain fabrics or wear them out faster, leading to more expenses down the road. Set up a line drying system instead to save energy.

41. Do only full laundry loads

Washing machines use about the same amount of energy for loads of any size. You can save a lot of energy by simply waiting until you have a full load of dirty laundry instead of frequent smaller loads. If you find yourself in a situation where you need to wash a smaller load, choose the correct water level setting to avoid wasting water.

On the other hand, avoid overloading your washer and dryer. This can wear out your appliances and your clothes will take much longer to dry.

42. Empty the dryer lint trap

Not only does cleaning the dryer lint trap save energy and money, it can also prevent a fire hazard. Make sure you and your family members dispose of lint every single time you wash and dry your clothes.

43. Buy some dryer balls

Wool or rubber dryer balls help separate your clothes and increase air flow, which cuts down on drying time so you don’t have to run the dryer as long. They can also reduce static so you don't need dryer sheets. Wool balls may also help absorb moisture, which can cut drying time even further.

44. Keep your dryer clean

Every few months, inspect your dryer to see if it needs cleaning. Check the dryer vent to make sure it’s not blocked by lint or debris. This can save energy and may also help you prevent a fire.

45. Upgrade your laundry room

If you have an older washer or dryer, it may be time for an upgrade. Look for an ENERGY STAR® or EnergyGuide label. These washing machines use nearly 35% less water and 25% less energy than standard washing machines. That can add up to lots of savings on your electricity bill every month!

ENERGY STAR dryers use 20% less energy than older models. Look for a dryer that has a moisture sensor that automatically shuts off the machine when your clothes will dry. This will prevent over-drying, which can help your clothes last longer, and save energy. Another energy-saving option you can try is an ENERGY STAR certified heat pump dryer, which can save 20–60% more energy than conventional models.

46. Old dryers waste energy

Even if you can’t afford to purchase a brand-new ENERGY STAR dryer, you may be able to find a newer model that’s lightly used at garage sales or on Facebook Marketplace. Older dryers are inefficient and can waste a lot of energy.

47. Buy energy-efficient appliances

Appliances grow more energy-efficient every year. Upgrading your appliances to ENERGY STAR models can reduce your energy costs significantly, both saving you money and helping the environment. Replace your oldest appliances that demand the most energy first for maximum savings.

Resources for energy-efficient appliances:

53. Use dimmer switches

Although dimmer switches are mostly known for their ability to create mood lighting, they also help you save energy! They reduce energy flowing to the light bulb by rapidly turning on and off the light fixture. This extremely fast flickering looks like a constant flow of light to human eyes.

54. Use smart power strips

Smart power strips eliminate the need to manually turn off your “energy vampire” electronics. They detect when devices are not in use, and cut off the energy flow to help you save. Some smart power strips even let you manage them from an app on your phone, so you can turn them off remotely or set automated schedules.

55. Install and use ceiling fans

Ceiling fans circulate the air and help you cool down without using your HVAC system, the biggest source of energy usage in most homes. They can also be reversed and used to blow down warm air to help keep you comfortable in colder months. Using a ceiling fan instead of turning on the air conditioning is a simple way to reduce your electricity bill every month.

57. Ask for discounted utility rates

Check with your energy provider to see if they offer programs that provide discounted utility rates during off-peak hours or solar generation credits.

58. Consider a prepaid electric bill plan

Prepaid electric bill plans let you pay for your energy before you use it to eliminate unnecessary fees. For example, with EPB PrePay, customers no longer need to pay late fees, reconnect fees or security deposits. Simply add funds to your account when you can. You can even pay smaller amounts daily, weekly or biweekly if that works better for your budget. Check with your energy provider to see if there’s a prepaid plan available for you.

59. Go solar

Installing solar panels on your roof requires large upfront costs, but could eventually pay for itself in energy savings. You can also join a solar community, like EPB Solar Share, that lets you lease solar panels from a community solar array. At the end of the month, you’ll earn credits from the solar energy your panels generated.
