Why Your Electric Bill Spikes in Winter, and How to Cut It

The average American home paid $132.99 for electricity in October 2025 and $175.11 in January 2026, by a calculation from Energy Information Administration (EIA) utility data that divides residential revenue by residential customer accounts. In Maryland the same two months went from $147.29 to $271.43. Over those months the average price of a kilowatt-hour (kWh) fell, from 17.97 cents to 17.45 cents nationally and in 39 of 51 jurisdictions (the 50 states plus the District of Columbia). On average the winter jump comes from usage, not price: the average home used 740 kWh in October and 1,003 kWh in January. The likely sources of those extra kilowatt-hours are a short list of machines, and the cheap fixes follow.

How much higher is a winter electric bill?

The table uses EIA’s monthly utility filings (Form EIA-861M, figures EIA labels preliminary, as downloaded September 25, 2026) divided by the number of residential customers, so each row is a state’s average home, gas-heated and electric-heated mixed together. Selected states, sorted by the change:

Usage roughly doubled in Maryland, West Virginia and Virginia, while homes in Texas, Florida and Arizona used less electricity in January than in October. A December 2016 EIA article on the winter rise named several of the suspects below: shorter days mean more lighting, and some homes heat with electricity, either as the main system or with space heaters and electric blankets.

Is it the rate or your usage?

Your bill prints both numbers. Divide the dollar total by the kWh used and compare that price with an autumn bill; if the price barely moved and the kWh jumped, the fix is in the house, not in a call to the utility. Nationally, the price fell between October and January while usage rose 36%.

If a big January bill is the problem more than the yearly total, ask about budget billing. Washington’s utility regulator describes it as a plan where “the amount is calculated using a 12-month average of your energy usage,” so “instead of paying higher bills in the winter and lower bills in the summer, you pay about the same amount each month.” The same page notes the utility re-checks the account and adjusts the payment, so budget billing spreads the cost rather than cutting it.

Will your electric bill be higher this winter?

If you heat with electricity, the federal forecast says a little higher on average, though not in the Northeast. EIA’s Winter Fuels Outlook for 2026-27, published October 6, 2026, covers November through March, and for homes that heat mainly with electricity it says “we expect a 3% increase in residential electricity prices and slightly higher consumption will lead to a 4% increase in electricity bills.” The forecast by region:

Those rows describe homes whose main heat is electric, and they count every use of electricity in the home over the five months, not only the heating: EIA says its consumption values “are for all end uses associated with a home’s main heating fuel.” They are not comparable with the first table, which shows single months of measured bills for all homes; these are five-month forecast totals for electric-heated homes only. The US average is forecast to peak at $270 in January, against $213 in November. The West stands out because of the weather assumption: EIA expects “a 9% increase in consumer outlays for electricity because of colder weather” there.

If you heat with gas, the same outlook expects the average gas-heated home to spend 9% less on natural gas, $640 for the five months, with drops of 10% to 15% in the Northeast, Midwest and South and a 7% rise in the West. It follows each home’s main heating fuel, so it has no electric-bill line for a gas-heated home; the part that applies is the electricity price, which EIA forecasts up 3% as a US average: 4% in the Northeast, Midwest and South, and 1% in the West.

Treat all of it as a forecast. EIA publishes side cases in which every region is “either 10% colder or 10% warmer than the base forecast,” warns that a strong El Niño pattern “could lead to large temperature variations from our forecast,” and says it will update the numbers through the winter. The outlook’s own description of its household figures is “a broad guide to compare the upcoming winter with the previous winter.”

Why is your electric bill so high in winter with electric heat?

Electric heat is common: 42% of US households named electricity as their main heating fuel in 2024, against 47% for natural gas, according to Census Bureau survey estimates cited by EIA. How much a cold month costs depends on which kind of electric heat you have.

Heat pumps and their backup strips. The Department of Energy’s (DOE’s) Energy Saver heat-pump page gave an example using a season-long efficiency rating: a heat pump rated 10.3 on the heating seasonal performance factor (HSPF) scale “provides 10,300 Btu of heat for every kWh of electricity consumed,” while “an electric resistance heating element provides only ~3,400 Btu of heat for every kWh.” A Btu is a British thermal unit, a fixed amount of heat. DOE’s 2022 guide puts the difference at about half: heat pumps “can reduce your electricity use for heating by approximately 50% compared to electric furnaces or electric baseboard heaters.” DOE’s current Home Upgrades page puts it higher: “Today’s heat pump can reduce your electricity use for heating by approximately 65% compared to electric resistance heating such as furnaces and baseboard heaters.” The expensive hours come when the heat pump needs help. Below a house’s “balance point,” which DOE said “is usually well below 40°F for code-built homes,” the system “utilizes auxiliary heat to help meet the load on the house,” and the same page described that backup as “auxiliary electric resistance back-up heat.”

Some of that strip heat is avoidable. DOE warned that “many heat pump controls are incorrectly wired to automatically turn on the auxiliary strip heat if the indoor thermostat is changed by more than 3 degrees F regardless of the outdoor temperature.” If the auxiliary heat comes on after every morning warm-up, a big overnight setback may be switching on the most expensive heat in the house. DOE’s guide says not to set back a heat pump “without a smart or programmable thermostat designed for use with heat pumps.”

Baseboard heaters and electric furnaces are the kind of electric heat that DOE’s guide says a heat pump beats by about half. Baseboard heat needs its own kind of thermostat: DOE said electric baseboard heating requires “thermostats capable of directly controlling 120-volt or 240-volt circuits.” The setback and draft-sealing steps below apply to these homes directly.

Why is your electric bill high in winter when you have gas heat?

Gas heats the air, but electricity moves it. DOE’s 2014 furnace-fan announcement said “a standard furnace fan for a 70,000 Btu per hour furnace consumes approximately 1,000 kilowatt-hours per year,” and that the new efficiency standard it announced “could reduce energy use by 46 percent.” Priced at January’s average rate, 1,000 kWh is about $175. The same fans “circulate air through ductwork in residential heating and cooling equipment,” so that use is spread across winter and summer.

The other culprits in a gas-heated home:

• Space heaters in the cold rooms. Consumer Product Safety Commission (CPSC) staff bought 27 portable electric heaters for a 2023 assessment, and 22 of them listed a 1,500-watt maximum. One heater like that is the biggest single line in the table below.
• An electric water heater, if you have one. Gas-heated homes are more likely to heat water with gas too, EIA notes. Across all US homes, water heating was 12% of residential electricity use in 2020, tied with space heating; in a home with an electric tank the share is larger. A National Renewable Energy Laboratory (NREL) model has the temperature of water arriving from the mains follow outdoor temperature over the year, and notes that mains temperature “has significant influence on the energy consumption of water heating equipment.”
• Lights on longer evenings. The 2016 EIA article listed “more lighting usage” among the reasons winter consumption rises.

What the common plug-in culprits cost a month

Costs below use the January 2026 national average of 17.45 cents per kWh and 30 days, at each device’s full rated power. A thermostat that cycles the device brings the real figure down, so read each plug-in row as a ceiling for the hours shown, and multiply by your own price from the bill. The furnace-fan row is a yearly figure spread evenly, so a heating-season month can run above it.

The heater wattages are from Lasko’s 754200 spec page (“900 W to 1500 W”). Sunbeam lists 110 watts for its heated mattress pad and 100 watts for a heated blanket. The heat cable is Frost King’s “7 Watts per foot,” and its thermostat only switches the cable on when the pipe temperature drops below 38°F, so the full-month figure is a ceiling. The furnace-fan row spreads DOE’s 2014 yearly figure evenly over twelve months; a fan built to the newer standard uses less.

How to stay warm on a budget

Heat yourself, not the house

A heated blanket at 100 watts draws one-fifteenth of what a 1,500-watt space heater does. Eight hours of it costs at most about $4 a month at the January average price, against about $63 for the heater on high. DOE makes the same point about clothes: “You can significantly reduce the amount of heat needed to keep your family cozy and comfortable by dressing in warm clothes and layers and throwing on blankets to retain body heat so you can lower those thermostats.”

Heat only the rooms you use

A space heater can save money in some cases. DOE: “In some cases, small space heaters can be less expensive to use if you only want to heat one room or supplement inadequate heating in one room.” That only pays off if the rest of the house is turned down, since a heater added on top of the normal setting is extra load. When you buy one, DOE’s checklist was a thermostat, because thermostatically controlled heaters “avoid the energy waste of overheating a room,” plus “a unit with a tip-over safety switch” that carries “the Underwriter’s Laboratory (UL) label.” Check for a safety-lab mark on the heater itself: of the 27 heaters CPSC staff bought, six carried no third-party certification marking at all.

Shutting supply vents on a forced-air system is a different story. A 2003 DOE-funded study by Lawrence Berkeley National Laboratory (LBNL) combined lab measurements with computer simulations of a typical California house with ducts outside the living space. In those simulations “in every case the closing of registers led to increased energy consumption,” because the savings were “offset by increased duct system losses; mostly due to increased duct leakage.” The study also warned that closing more than 60% of registers can make a furnace “operate on the high-limit switch.” If your ducts run through an attic, crawl space or garage, leave the vents in unused rooms open.

Turn the thermostat back when you are asleep or out

DOE’s current guidance: “You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 7°-10°F for 8 hours a day from its normal setting.” Its thermostat page suggested “around 68°F to 70°F while you’re awake and setting it lower while you’re asleep or away from home,” and noted that “the lower the interior temperature, the slower the heat loss.” Heat-pump owners should use a thermostat designed for heat pumps, for the backup-strip reason above. If you want a thermostat that does this on its own, the smart thermostat guide compares the current models and explains why baseboard heat needs a separate line-voltage thermostat.

Use the sun, the curtains and the ceiling fan

DOE’s guide: “Open draperies and shades on your south-facing windows during the day to allow the sunlight to enter your home. Close them at night to reduce the chill from cold windows.” DOE’s window page estimated that “about 30% of a home’s heating energy is lost through windows,” that when drawn in cold weather “most conventional draperies can reduce heat loss from a warm room up to 10%,” and that tightly installed cellular shades “can reduce heat loss through windows by 40% or more, which equates to about 10% heating energy savings.” Ceiling fans help too: “In winter, reverse the fan to run clockwise and force warm air down from the ceiling.”

Find the drafts, with a borrowed thermal camera if you can

Start free. DOE’s home-assessment guide suggests closing a door or window on a piece of paper: “If you can remove the paper without tearing it, you have an air leak.” Its fuller test, done on a cool, windy day, runs in this order: close all exterior doors, windows and fireplace flues; turn off combustion appliances such as gas furnaces and water heaters; turn on the exhaust fans that blow air outside, such as bathroom fans and stove vents; then “light a smoke candle or incense stick and pass it around the edges of common leak areas. If smoke is drawn into or out of a room, then there is an air leak.” The places to check include “electrical outlets, switch plates, windows and door frames, baseboards, attic hatches,” and spots where different materials meet, such as between the foundation and the walls.

In a professional scan, temperature differences “show up in a video or camera still image as whiter (warmer) or darker (cooler) areas,” according to the same guide. Fairfax County’s library says its lendable cameras “use color to show the relative temperature of different objects.” A scan works best, DOE said, when there is “a large temperature difference” of at least 20°F “between inside and outside air temperatures,” so a cold evening beats a mild afternoon. You do not have to buy one. Some public libraries lend thermal cameras that work with a phone, like books: Montgomery County, Maryland, lends them for 14 days to cardholders at least 14 years old; Fairfax County, Virginia, lends a FLIR ONE Edge for two weeks; and Arlington, Virginia, lends them through its energy lending library. Ask your own library, and note Fairfax’s remark that “some large home improvement stores may have thermal cameras for purchase or rental.” Buying your own, Teledyne FLIR’s store listed its FLIR ONE phone camera at $249 on October 11, 2026. If a friend owns one, borrow it on a cold evening.

Seal what you find

Use the right material for the gap. DOE: “You can use weatherstripping in your home to seal air leaks around movable building components, such as doors or operable windows. For stationary components, caulk is the appropriate material for filling cracks and gaps.” Caulk is for cracks “less than 1-quarter-inch wide,” expect “a half-cartridge per window or door,” and apply it “when the outdoor temperature is above 45°F,” so the job belongs before the hard cold arrives. The payoff can be real: the Environmental Protection Agency’s (EPA’s) ENERGY STAR program estimates, from energy modeling of typical homes, that homeowners “can save an average of 15% on heating and cooling costs” by air sealing and adding insulation in attics, floors over crawl spaces and accessible basement rim joists, with bigger savings in the North than the South.

Burn wood the right way, or not at all

An open fireplace is usually a net energy loser. DOE: “Traditional fireplaces draw in as much as 300 cubic feet per minute of heated room air for combustion, then send it straight up the chimney,” and “most traditional fireplaces are still energy losers.” DOE’s advice was to close the flue “when the fireplace is not in use” (in practice, once the fire is completely out) and to plug and seal it if you never use the fireplace. For wood heat that pays, EPA’s now-archived Burn Wise program said replacing an old wood heater or fireplace with an EPA-certified appliance can save fuel and money, and listed a certified stove’s benefits as “up to 50% more energy efficient” and “use 1/3 less wood fuel for the same heat.” Burn dry wood only: EPA’s page said properly dried wood “should have a reading of 20% or less” and to split it, stack it off the ground, cover the top, and store it at least 6 months for softwood and 12 for hardwood. Have the chimney checked or cleaned every year, as both the Centers for Disease Control and Prevention (CDC) and the National Fire Protection Association (NFPA) advise; NFPA says to do it before the heating season starts, and the CDC notes a blocked chimney can let carbon monoxide build up inside.

Keep the pipes from freezing

Among the pipes the American Red Cross lists as freezing most often are supply lines “in unheated interior areas like basements and crawl spaces, attics, garages, or kitchen cabinets” and pipes on poorly insulated exterior walls. The Red Cross suggests a pipe sleeve, or UL-listed heat tape or heat cable, on exposed water pipes. A thermostat-controlled cable like Frost King’s switches on when the pipe drops below 38°F and off above 45°F, so a 6-foot kit costs at most about $5.28 a month at the January average price. Follow the maker’s rules: Frost King says never to overwrap the cable, never to install it in walls, floors or ceilings, that its cables “aren’t made for PVC pipes,” though the same page allows plastic water pipes that are “primary supply pipes” marked Schedule 40, and to cover the cable with non-combustible insulation. It also rules out mobile-home feed lines and hoses, so check the instructions against your own pipe, and check the package for a safety-lab listing. On the coldest nights, open the cabinet doors under sinks (moving cleaners and chemicals out of children’s reach), “let the cold water drip from the faucet served by exposed pipes,” and if you travel, leave the heat “no lower than 55° F.” This is the one place not to save: the Red Cross says to keep the same thermostat setting day and night while pipes are at risk, because a burst pipe is a much more costly repair than a higher heating bill. Never thaw a pipe with “a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device.”

Stay safe while you save

Heating is a winter fire risk. NFPA estimates fire departments responded to an average of 37,365 home heating-equipment fires a year from 2020 to 2024, 46% of them from December through February, and space heaters and heating stoves together accounted for 73% of the deaths. Keep a space heater at least 3 feet from anything that can burn and turn it off when you leave the room or go to bed. The US Fire Administration (USFA) says to plug space heaters “directly into wall outlets and never into an extension cord or power strip”; DOE’s archived guidance allowed only “the shortest possible heavy-duty cord of 14-gauge wire or larger” if a cord is necessary, and added: “Always check and follow any manufacturer’s instructions pertaining to the use of extension cords.” The CDC is blunt about carbon monoxide (CO): “Never heat your house with a gas oven,” never burn charcoal indoors, and never run a generator “inside your home or garage, even if doors and windows are open.” Put a battery-powered or battery-backup CO detector near every sleeping area. For outage heat, the power station sizing guide shows why a battery cannot run a space heater for long, and the generator comparison covers running a generator safely.

Help if you cannot pay the winter bill

The federal Low Income Home Energy Assistance Program (LIHEAP) helps with “home heating bills, preventing energy shutoffs, reconnecting services, making homes more energy efficient, and repairing or replacing heating equipment.” For where and how to apply in your area, the Department of Health and Human Services (HHS) points to its EnergyHelp site and to the National Energy Assistance Referral hotline at 1-866-674-6327, weekdays 9 a.m. to 7 p.m. Eastern. HHS also warns that LIHEAP “does not provide direct grants to individuals” and does not charge a fee, and asks you to report any message offering a LIHEAP grant or asking for a fee to its fraud hotline at 1-800-447-8477.

DOE’s Weatherization Assistance Program (WAP) sends an energy auditor to the home, then crews or contractors carry out “the most cost-effective energy conservation measures for your home.” To apply, DOE says to “first identify your state weatherization administrator and reach out to them.” Weatherized households “save on average $372 or more every year,” according to DOE’s national evaluation. Under DOE’s guidelines, households at or below 200% of the poverty income guidelines or receiving Supplemental Security Income are eligible, states may also use LIHEAP’s 60%-of-state-median-income test, and priority goes to older residents, people with disabilities, families with children, high energy users and households with a high energy burden. Renters can apply, but the provider needs the landlord’s permission before work starts, and eligible households go on a waitlist.

Finally, check your state’s shutoff rules before a bill goes unpaid. The federal LIHEAP Clearinghouse counted 42 states with cold-weather disconnection protections in its 2026 summary, but it notes they “generally apply to regulated utility companies,” generally not to municipal utilities or rural electric cooperatives, and that utilities keep billing while disconnections are restricted. Some states protect only on days below a set temperature, such as Alabama at “32°F or below.” A protection delays a shutoff; it does not erase the balance. If the due date falls before your money arrives, Washington’s regulator advises contacting the utility, offering alternative dates, and making only arrangements you can keep, because in Washington “if you do not meet arrangements that you have agreed to, the company can disconnect your service without notice.”
