9 Ways to Lower Your Electric Bill Before Winter Hits

You can lower your electric bill before winter with a handful of free or cheap fixes: set the thermostat back 7 to 10 degrees at night, drop the water heater to 120°F, seal drafts, swap in LED bulbs, and cut standby power. Stacked together, they can realistically save $10 to $30 a month.

Why Is Your Electric Bill Climbing This Winter?

EIA data show the average residential rate hit 18.83 cents per kWh in April 2026, up 7.3% from a year earlier. A kilowatt-hour (kWh) is the unit utilities bill in: one 1,000-watt appliance running for one hour. A typical home uses about 900 kWh a month, which works out to roughly $165 a month at 2026 rates. The good news is that the fixes below target the biggest winter bill drivers.

The 9 Best Ways to Lower Your Electric Bill Before Winter

1. Set Your Thermostat Back 7 to 10 Degrees at Night

How It Works: Heat escapes faster when the gap between indoor and outdoor temperatures grows, so a cooler house loses less energy while you sleep or work. The DOE says the idea that your furnace works extra hard to catch up is a myth. Aim for about 68°F while awake, then drop 7 to 10 degrees for 8 hours a day.

Real Example: A smart thermostat such as a Nest or ecobee can run the schedule for you: 68°F by day and 61°F from 10 p.m. to 6 a.m.

Estimated Savings: Up to 10% a year on heating and cooling costs, per the DOE. If those make up $80 of a $165 winter bill (our illustration), that is up to $8 a month.

Pros and Cons: Pros: free with any thermostat. Cons: heat pumps can trigger costly backup heat when set back, so use a heat-pump-rated model, per the Maryland Energy Administration.

Action Step: Program it tonight: 68°F awake, 61°F overnight.

2. Turn Your Water Heater Down to 120°F

How It Works: Tank water heaters reheat water around the clock because heat leaks through the tank walls. Many ship set to 140°F, but the DOE says most households only need 120°F, which also slows mineral buildup. It is a five-minute dial turn.

Real Example: On an electric unit, shut off the breaker, open the panel, mark the dial, turn it down, then check the temperature at the farthest tap two hours later.

Estimated Savings: $36 to $61 a year in avoided standby heat loss versus 140°F, according to the DOE.

Pros and Cons: Pros: free and fast. Cons: check your dishwasher manual first, and ask a pro if anyone at home has special hot-water needs.

Action Step: Find the thermostat dial this weekend and set it to 120°F.

3. Seal Air Leaks Around Doors, Windows, and the Attic

How It Works: Leaky homes let heated air out and cold air in, so your system runs longer. Caulk cracks, add weatherstripping to doors, and foam-seal gaps around pipes and outlets. ENERGY STAR says air sealing plus added insulation saves about 15% on heating and cooling on average, and whole-home savings run from about 5% in the warmest climate zone to 16% in the coldest.

Real Example: Grab a roll of Frost King weatherstripping and a tube of caulk at a hardware store, then start with the front door and the attic hatch.

Estimated Savings: About 15% of heating and cooling costs on average (EPA), but that figure includes attic insulation, so caulk and weatherstripping alone save less.

Pros and Cons: Pros: cheap, DIY-friendly, and warmer rooms. Cons: the biggest gains often need insulation work.

Action Step: Close a door on a dollar bill. If it slides out easily, replace that seal.

4. Swap Your Most-Used Bulbs for LEDs

How It Works: Lighting is about 15% of an average home’s electricity use, and winter’s early darkness keeps bulbs on longer. LEDs use up to 90% less energy and last up to 25 times longer than incandescent bulbs. Replace the bulbs you use most first.

Real Example: Swapping your five most-used lights for ENERGY STAR LEDs can save up to $75 a year, per Home Depot’s summary of DOE data.

Estimated Savings: Up to $225 a year for the average household that switches fully, per the DOE.

Best For: Homes still running incandescent or halogen bulbs. Skip this one if you already use LEDs.

Action Step: Pick the three lights that run longest each day and replace those first.

5. Cut Standby Power With Smart Strips

How It Works: Phantom load, also called standby power, is the electricity devices draw while off or idle. TVs, game consoles, cable boxes, and chargers all sip power around the clock, and the average household spends $100 to $200 a year on it. A smart or advanced power strip cuts power to devices that are off.

Real Example: A TP-Link Kasa smart plug or an advanced power strip on the TV stand and the home-office desk covers the two biggest clusters.

Estimated Savings: $100 to $200 a year, or roughly $8 to $17 a month.

Pros and Cons: Pros: no lifestyle change. Cons: DVRs and cable boxes can lose recordings or restart slowly, so leave those plugged in.

Action Step: Plug the TV, soundbar, and console into one switchable strip and flip it off at bedtime.

6. Run Heavy Appliances During Off-Peak Hours

How It Works: A time-of-use (TOU) plan charges different rates by the hour, so the same kilowatt-hour costs less overnight than at dinnertime. Dishwashers, dryers, and EV chargers can all wait. Not every utility offers one, so you have to ask.

Real Example: Minnesota Power’s Time-of-Day rate runs about 16 cents on-peak, 10 cents off-peak, and 7 cents super off-peak, versus a 10.8-cent flat rate in 2026. Potomac Edison’s new Maryland TOU rate launched in April 2026 at about 9 cents off-peak versus 16 on-peak, roughly 44% less.

Estimated Savings: Moving 100 kWh a month from 16 cents to 9 cents saves about $7 a month (our math from the Potomac Edison rates).

Pros and Cons: Pros: no equipment needed. Cons: you pay more at peak, so skip it if your usage clusters on weekday evenings.

Action Step: Call your utility, ask about TOU plans, and use the delay-start button on your dishwasher.

7. Replace Your Furnace Filter

How It Works: A clogged filter chokes airflow, so your blower runs longer to move the same heat. The DOE says a clean filter can cut an air conditioner’s energy use by 5% to 15%. The same airflow logic applies to forced-air heating, but the DOE figure is for cooling, so treat heating savings as an upside.

Real Example: Pleated filters from brands like Filtrete come in standard sizes printed on the frame. Hold the old one up to a light, and if little light passes through, swap it.

Estimated Savings: Up to 5% to 15% of cooling energy per the DOE, with heating gains likely smaller.

Best For: Forced-air homes. Skip this one if you heat with baseboards or radiators.

Action Step: Check your filter today and set a monthly phone reminder.

8. Plug Window Heat Leaks

How It Works: Windows make up only about 10% of a typical home’s surface area, yet the DOE says they account for 30% to 40% of winter heat loss. Insulating shades, thick curtains, and window film slow that down. On sunny days, open south-facing curtains for free heat, then close them at dusk.

Real Example: Hunter Douglas Duette cellular shades are the premium route, and 3M’s Indoor Window Insulation Kit is the budget film option. DOE-backed Oak Ridge National Laboratory studies found cellular shades cut heating energy needs by almost 25%.

Estimated Savings: Up to about 25% of heating energy with cellular shades in the best case. Curtains and film save less.

Pros and Cons: Pros: the open-by-day, close-at-dusk habit is free. Cons: quality cellular shades cost real money.

Action Step: Start the open-and-close habit tomorrow and note which rooms feel warmer.

9. Claim Rebates, Free Audits, and Bill Help

How It Works: The federal 25C home-efficiency tax credit ended for work after December 31, 2025, so local programs matter more now. Ask your utility about rebates and energy audits. Income-qualified households can also apply for LIHEAP, which received about $4.05 billion for 2026, with eligibility capped at 150% of the poverty line or 60% of state median income.

Real Example: Rhode Island’s LIHEAP application letter says eligible RI Energy customers can still get a 25% discount on electric or gas bills and can start weatherization screening. Its deadline was April 15, 2026.

Estimated Savings: Varies by state. A 25% discount on a $165 bill would be about $41 a month (our math).

Pros and Cons: Pros: real cash and weatherization help. Cons: LIHEAP is not an entitlement, funds are limited, and windows close, so apply early.

Action Step: Search your state’s LIHEAP office and call your utility’s rebate line this week.

Frequently Asked Questions

What is the fastest way to lower my electric bill before winter?

Set your thermostat back 7 to 10 degrees for 8 hours a day. The DOE says that can save up to 10% a year on heating and cooling, and it costs nothing.

What temperature should I set my thermostat to in winter?

About 68°F while you are awake, and lower while you sleep or are away. The deeper and longer the setback, the more you save.

Does unplugging devices really save money?

Yes, though modestly. Sonoma Clean Power puts the average household’s standby cost at $100 to $200 a year, and a switchable power strip captures most of it.

Is a time-of-use electricity plan worth it?

It is worth it only if you can shift heavy use off-peak. Potomac Edison’s off-peak rate is about 44% below its on-peak rate, but usage at peak costs more than a flat plan.

Are there programs that help pay my electric bill?

Yes. LIHEAP and the Weatherization Assistance Program help income-qualified households, and states set the application windows. The federal 25C tax credit ended for work after December 31, 2025, so also ask your utility about rebates.
