Your electric bill is one of those expenses that feels fixed — like there’s a number, you pay it, and that’s that.
It isn’t fixed. Not even close.
The average American household spends around $130-150 a month on electricity. Most of that spending is driven by habits and setups that are easy to change — not by some unavoidable baseline cost. Small adjustments to how you use electricity at home compound into meaningful monthly savings that show up on every single bill, permanently.
None of the 20 strategies in this guide require expensive upgrades or major home renovations. Most cost nothing at all. They’re changes in habit, settings, and awareness that reduce what you use — and therefore what you pay.
We covered some of these briefly in our how to save money on utilities and how to cut your monthly bills guides. This article goes deeper with a complete focus on electricity — the category with the most room to save for most households.
Understanding Your Electric Bill First
Before cutting costs, it helps to know where electricity actually goes in a typical home:
| Category | Approximate % of Electric Bill |
|---|---|
| Heating and cooling (HVAC) | 40 – 50% |
| Water heating | 14 – 18% |
| Washer and dryer | 5 – 7% |
| Lighting | 5 – 7% |
| Refrigerator | 4 – 6% |
| Television and entertainment | 3 – 5% |
| Dishwasher | 2 – 3% |
| Everything else | 10 – 15% |
The message from these numbers is clear: heating, cooling, and water heating together account for more than half your electric bill. If you want to make a significant dent in what you pay, those are the categories that matter most — not the lights you leave on in the hallway.
That said, every category has room to improve. Here are 20 ways to do it.
Heating and Cooling (The Biggest Wins)
1. Lower Your Thermostat by 2 Degrees in Winter
For every degree you lower your thermostat in winter, you save approximately 1-3% on your heating bill. Dropping two degrees saves 2-6% with minimal impact on comfort — most people adjust within a day or two.
Put on a sweater. Use a blanket on the couch. The adjustment is smaller than you expect and the saving is immediate and permanent.
2. Raise Your Thermostat by 2 Degrees in Summer
The same logic applies in reverse for cooling. A thermostat set to 78°F instead of 74°F in summer uses significantly less energy — and with a ceiling fan running (which makes the room feel 3-4 degrees cooler), 78°F is comfortable for most people.
THRIFTY HABIT #50 The US Department of Energy recommends 68°F when home in winter and 78°F when home in summer as the sweet spot between comfort and efficiency. If your current settings are more extreme than these in either direction, adjusting them is the single highest-return change you can make to your electric bill.
3. Use a Programmable or Smart Thermostat
Manual thermostat adjustments require remembering to do them. A programmable thermostat does it automatically — lower heat while you’re at work, bring it back up before you get home, reduce it again overnight.
The Department of Energy estimates that dialing back the thermostat 7-10°F for 8 hours a day saves around 10% annually on heating and cooling costs. A programmable thermostat makes this happen without any daily effort.
Smart thermostats like the Google Nest or Ecobee go further — they learn your schedule and preferences over time. They cost $100-250 upfront but typically pay for themselves within a year through energy savings.
4. Change Your HVAC Filter Regularly
A clogged air filter makes your heating and cooling system work significantly harder to push air through — using more electricity to maintain the same temperature.
Check your filter monthly and replace it every 1-3 months depending on your household (more frequently with pets or allergies). A $5-10 filter replacement is one of the highest-return maintenance tasks you can do.
5. Use Ceiling Fans Strategically
Ceiling fans don’t cool rooms — they cool people by creating a wind chill effect. This distinction matters because it means you should turn them off when you leave the room.
Used correctly, ceiling fans let you raise your thermostat 3-4 degrees without reducing comfort — meaningful savings on your cooling bill throughout summer.
In winter, reverse your ceiling fan direction (clockwise on low speed) to push warm air that rises to the ceiling back down into the room. Most ceiling fans have a small switch on the motor housing for this.
6. Seal Air Leaks Around Doors and Windows
Drafts let conditioned air out and outside air in — forcing your HVAC system to work harder to compensate.
A few dollars of weatherstripping tape on window frames, a door draft excluder on exterior doors, and foam outlet covers on electrical outlets on exterior walls can meaningfully reduce the workload on your heating and cooling system.
As we covered in the utilities guide, a candle or your hand on a windy day will quickly reveal where drafts are coming from in your home.
7. Close Vents in Unused Rooms
If you have rooms you rarely use — a guest bedroom, a storage room, a formal dining room — close the heating and cooling vents in those rooms and keep the doors shut.
You’re reducing the volume of space your system has to condition. Less space equals less energy equals lower bill.
Water Heating
8. Lower Your Water Heater to 120°F
Most water heaters come factory-set to 140°F — hotter than necessary for household use and a source of wasted energy around the clock.
Lowering to 120°F reduces standby heat loss (the energy used just to keep the water hot while you’re not using it) and cuts water heating costs by 4-22% depending on your usage. It also eliminates the scalding risk for children and elderly household members.
Find the thermostat on your water heater (usually behind a panel on the unit), adjust the dial, done. A five-minute change that saves money every month indefinitely.
9. Take Shorter Showers
Water heating is the second-largest electricity consumer in most homes. Shorter showers directly reduce how much hot water you use — and therefore how much energy is spent heating it.
Cutting two minutes off your daily shower saves meaningful hot water per person per year. In a household of four people, that’s a significant reduction in water heating demand.
THRIFTY HABIT #51 Set a shower timer using your phone. Most people significantly underestimate how long they shower until they time it. A seven-minute shower isn’t very different from a ten-minute shower in terms of how clean you get — but it’s meaningfully different on your electric bill multiplied by 365 days.
10. Wash Laundry on Cold
About 90% of the energy used by your washing machine goes to heating the water. Switching from hot or warm to cold for most loads almost eliminates that energy use entirely.
Modern detergents are formulated for cold water. Your clothes get just as clean. The only loads that genuinely benefit from hot water are heavily soiled items or specific sanitizing situations — your regular weekly laundry is not one of them.
Appliances and Devices
11. Switch All Bulbs to LED
If any incandescent or CFL bulbs remain in your home, replacing them with LED is one of the clearest electricity savings available.
LED bulbs use 75-80% less energy than incandescent bulbs and last 15-25 times longer. A 60-watt incandescent replaced by a 9-watt LED saves about $7 per bulb per year in electricity — multiplied across every bulb in your home, the annual saving is significant.
LED bulb prices have dropped dramatically. A pack of bulbs now costs a few dollars. The payback period is short and the saving continues for years.
12. Unplug Devices Not in Use — Or Use Smart Power Strips
Phantom load — the electricity drawn by devices in standby mode — accounts for approximately 10% of the average household’s electric bill.
The worst offenders: game consoles, cable boxes, streaming devices, microwaves (the clock runs constantly), coffee makers, TVs in standby, and phone chargers left plugged in with nothing connected.
Smart power strips automatically cut power to devices in standby mode. Regular power strips work too — one switch turns off everything connected. The habit of turning off a power strip when you leave a room eliminates phantom load from that entire circuit.
THRIFTY HABIT #52 Walk through your home and count every device with a standby light or clock display. Each one is drawing power 24 hours a day. Multiply that across your whole house and the phantom load adds up to a meaningful monthly cost that disappears the moment you start managing it.
13. Run the Dishwasher Only When Full and Skip Heated Dry
A half-full dishwasher uses the same energy as a full one. Waiting until it’s completely full before running it immediately cuts the number of cycles per week.
Turn off the heated dry function — open the door after the wash cycle ends and let dishes air dry. Identical result, none of the energy.
14. Only Run Full Loads of Laundry
Same logic as the dishwasher. A washing machine uses nearly as much energy and water on a half load as a full one. Wait for a full load before running it.
If you need something specific washed urgently, hand wash it. For everything else, be patient and run full loads only.
15. Clean Your Refrigerator Coils
The condenser coils on the back or underneath your refrigerator dissipate heat as part of the refrigeration cycle. When they’re coated in dust and pet hair, the fridge has to work harder — using more electricity — to maintain its temperature.
Vacuum the coils once or twice a year. It takes ten minutes and noticeably improves refrigerator efficiency. Check your manual for coil location — usually on the back or behind a kick plate at the bottom front.
16. Check Your Refrigerator Door Seal
A damaged or worn door gasket lets cold air escape and warm air in continuously — forcing the fridge to run more than it should.
Test the seal with a piece of paper: close the door on it and try to pull it out. If it slides out easily, the seal isn’t creating adequate pressure and needs replacing. A replacement gasket costs $20-50 and is a straightforward DIY repair.
THRIFTY HABIT #53 Keep your refrigerator between 35-38°F and your freezer at 0°F. Many households run their fridge colder than necessary — check with a thermometer, not the dial setting, which is rarely calibrated accurately. A properly set fridge uses noticeably less energy than one running colder than needed.
17. Use Your Microwave Instead of the Oven When Possible
A microwave uses 50-80% less energy than a conventional oven for the same reheating or cooking task — because it heats food directly rather than heating the air around it.
For reheating leftovers, cooking vegetables, or any task where the oven isn’t specifically necessary for texture or result, the microwave is the cheaper choice every time.
18. Use Your Oven Efficiently When You Do Use It
When you do use the oven, use it efficiently:
- Don’t preheat longer than necessary — most ovens reach temperature in 10-15 minutes
- Avoid opening the door during cooking — every time you open it, 25-50°F is lost and the oven uses energy to recover
- Cook multiple things at once when possible — if the oven is on, use it fully
- Turn it off a few minutes early — residual heat finishes the job for most dishes
- Use a toaster oven for small tasks — it uses significantly less energy than a full-size oven for small portions
Lighting and Habits
19. Turn Off Lights When You Leave a Room
This is the oldest electricity-saving advice there is — and it still works.
LED bulbs use so little energy that the saving per bulb per hour is small. But across a whole house, across a whole day, across a whole month, the habit of turning off lights consistently adds up.
More importantly, it’s a gateway habit — the household that consistently turns off lights is also more likely to unplug devices, run full loads, and manage all the other electricity habits that compound into real savings.
THRIFTY HABIT #54 Put a sticky note on the light switches near your front door and main rooms for the first two weeks of building this habit: “Off when leaving.” The reminder breaks the automatic pattern of leaving lights on. After two weeks the habit is usually established and the note can come down.
20. Check Whether You Qualify for Time-of-Use Pricing
Many utility providers offer time-of-use (TOU) rate plans where electricity costs less during off-peak hours — typically late evening, overnight, and early morning — and more during peak demand periods (usually late afternoon and early evening on weekdays).
If your provider offers TOU pricing and your schedule allows flexibility, shifting high-energy tasks — running the dishwasher, doing laundry, charging electric vehicles — to off-peak hours can meaningfully reduce your bill without using any less electricity.
Call your utility provider or check their website to see if TOU plans are available in your area. Some providers offer them automatically; others require you to opt in.
How Much Can These Changes Actually Save?
Here’s a realistic breakdown for a household with a $140 monthly electric bill:
| Category | Strategy | Estimated Monthly Saving |
|---|---|---|
| Heating/Cooling | Thermostat adjustment + programmable thermostat | $14 – $28 |
| Water Heating | Lower water heater + shorter showers + cold laundry | $8 – $15 |
| Lighting | Full LED switch + lights off habit | $5 – $10 |
| Phantom Load | Unplugging + smart power strips | $10 – $18 |
| Appliances | Full loads only + dishwasher habits | $5 – $10 |
| Refrigerator | Coil cleaning + proper temp | $3 – $7 |
| Total Potential Saving | $45 – $88/month |
That’s $540-1,056 per year on electricity alone — from habits that cost nothing to implement and become automatic quickly.
Combined with the water and gas savings from our full utilities guide and the bill-cutting strategies in our cut your monthly bills guide, the total utility savings available to most households are genuinely significant.
Where to Start
If you’re looking at this list and wondering where to begin, start with the three changes that require zero cost and zero ongoing effort once set:
- Lower your water heater to 120°F — five minutes, permanent saving
- Switch remaining bulbs to LED — one afternoon, years of savings
- Set your thermostat 2 degrees closer to outside temperature — immediate saving every month
Those three alone could reduce your electric bill by $20-40 a month. Once you see the difference on your next bill, you’ll be motivated to tackle the rest.
