Your electric bill just went up again. Not because you changed anything, but because the average U.S. household now pays around $1,834 a year on electricity, and most of that money leaks out through habits so routine you've stopped noticing them. The thermostat gets all the attention when people talk about cutting costs. But there's a long list of things running in the background, quietly pulling from the grid, that have nothing to do with temperature.
None of what follows requires a contractor, a smart home setup, or a significant upfront investment. Most of it costs nothing.

Unplug devices that run on standby
The Department of Energy estimates that standby power accounts for 5 to 10 percent of residential electricity use, which works out to roughly $92 to $183 a year for the average household. That number comes from devices that appear to be off but are still drawing power: TVs, cable boxes, gaming consoles, coffee makers, phone chargers left plugged in after the phone is removed, microwaves blinking the time. Anything with a standby light, a digital clock, or a remote control is almost certainly using electricity around the clock.
The quickest fix is a power strip. Plug your entertainment system, gaming setup, or home office cluster into a single strip and switch it off when you leave the room or go to bed. Smart power strips go further and cut power to secondary devices automatically when the main device shuts off. If you want to know which appliances are actually costing you money, a kill-a-watt meter (usually under $25 at hardware stores) lets you measure the standby draw of any device by plugging it in between the appliance and the outlet.
The worst offenders tend to be anything with an “instant-on” feature: TVs, gaming consoles, soundbars, and streaming boxes. These stay partially on at all times so they respond immediately to a remote signal. That convenience has a real dollar cost per year, multiplied across every device in your home.
Turn your water heater down to 120 degrees
Most water heaters ship set to 140 degrees Fahrenheit. The Department of Energy recommends 120 degrees for most households, a setting that can reduce standby heat loss and cut overall water heating costs by 6 to 10 percent. Set too high, a water heater wastes $36 to $61 a year in standby losses alone, before accounting for the extra energy used heating water for showers, laundry, and dishes.
The adjustment takes about five minutes. For a gas water heater, the dial is usually on the control valve near the bottom of the tank. Electric water heaters have thermostats behind access panels, sometimes two of them, one upper and one lower. Turn off the circuit breaker first, then adjust both thermostats to match. Wait a couple of hours, then test the temperature at your farthest tap with a cooking thermometer. If your dishwasher doesn't have a booster heater, you may want to keep the setting at 130 degrees for effective cleaning.
At 120 degrees, the water is still hot enough to kill most common bacteria, still more than adequate for showers, and significantly less dangerous for households with young children or elderly adults. It also slows mineral buildup inside the tank, which extends the life of the appliance.
Clean your refrigerator's condenser coils
Your refrigerator runs 24 hours a day, 365 days a year, which makes it one of the most consequential appliances in the house from an energy standpoint. When the condenser coils, located either underneath the fridge behind the kick plate or on the back of the unit, get clogged with dust, pet hair, and kitchen grease, the compressor has to work harder to maintain temperature. The average energy savings after cleaning the coils is around 11 percent of the refrigerator's electricity use, and the task takes about 15 minutes.
The process is straightforward. Unplug the fridge, pull it away from the wall if the coils are on the back or remove the kick plate if they're underneath, and use a vacuum with a brush attachment or a coil-cleaning brush to clear the buildup. Plug it back in. That's the entire job. If you have pets that shed, doing this every three to four months keeps efficiency from dropping. Without pets, once or twice a year is typically enough.
The reason this matters more than most people expect is that the fridge never gets a day off. A dryer runs for 45 minutes. A refrigerator runs indefinitely. Even a modest efficiency loss from dirty coils compounds into real money over a year, and eventually accelerates wear on the compressor, which is the most expensive component to replace.
Wash laundry in cold water
About 75 to 90 percent of the energy a washing machine uses goes toward heating water. The wash cycle itself, the spinning and agitation, uses relatively little electricity compared to the heating element. Switching from a hot wash to cold saves approximately 3.2 kilowatt-hours per load. Run 300 loads a year, which is close to average for a U.S. household, and that adds up to enough electricity to run a refrigerator for nearly a year.
Modern cold-water detergents are formulated to clean effectively at lower temperatures, and cold water is actually gentler on fabric. Colors hold longer, synthetics don't shrink, and certain stains, particularly protein-based ones like blood and sweat, are more effectively removed in cold water because heat sets them into the fibers. The case for hot water mostly comes down to sanitizing: bedding after illness, cloth diapers, or items that need to be disinfected. For everyday clothing and towels, cold water does the job.
If you switch nothing else in your laundry routine, switch the temperature. It's the single highest-impact adjustment you can make per load, and it requires no investment.
Run laundry and appliances during off-peak hours
Many utilities charge different rates depending on the time of day you use electricity, a structure called time-of-use pricing. Peak hours, typically late afternoon and early evening on weekdays, are when demand on the grid is highest and rates are highest. Off-peak periods, usually overnight and on weekends, cost less. In some utility structures, the difference between peak and off-peak rates is significant enough that shifting laundry, dishwasher use, and phone or laptop charging to evenings or weekends produces real bill savings over the course of a year.
The first step is finding out whether your utility has time-of-use pricing. Log into your utility account or call customer service and ask what rate structure you're on and whether you're currently enrolled in a time-of-use plan. Not all utilities have this option, and some require you to opt in. If yours does offer it, the adjustment is mostly a matter of building different habits: start the dishwasher after 9 p.m., do laundry on Saturday morning instead of Thursday evening, and charge devices overnight.
Appliances with delay-start features make this easier. Most modern washers, dryers, and dishwashers let you set a delayed start so the machine begins running at a specific time. You load it when it's convenient and let it run when the rate drops.
Switch remaining incandescent bulbs to LEDs
Lighting accounts for about 15 percent of the average household's electricity use, and the Department of Energy estimates the typical household saves around $225 a year by switching fully to LEDs. The savings come from two directions: LEDs use at least 75 percent less energy than incandescent bulbs, and they last up to 25 times longer, reducing replacement costs.
If you still have incandescent bulbs anywhere in your home, start with the fixtures you use most. A single 60-watt incandescent replaced by an equivalent LED running five hours a day saves nearly $10 per bulb per year at average electricity rates. Replace five frequently-used bulbs and you're saving $40 to $50 annually on lighting alone, with no ongoing cost. LED bulbs now run anywhere from $2 to $8 per bulb depending on type, which means the payback period on the investment is measured in months, not years.
The common resistance to switching, that LED light looks harsh or clinical, was a legitimate concern a decade ago. The current generation of bulbs comes in a wide range of color temperatures, including warm white options that are visually indistinguishable from incandescent light. Look for the color temperature on the packaging: 2700K to 3000K is warm, comparable to incandescent. 4000K and above starts to feel cooler.
Use smart power strips for home office and entertainment setups
The problem with ordinary power strips is that they don't actually reduce standby power. They consolidate plugs, but unless you flip the switch on the strip itself, everything stays energized. Smart power strips, also called advanced power strips, work differently. They monitor the power draw on a designated “master” outlet, and when that device drops into standby or turns off, the strip automatically cuts power to all connected devices.
For a home office setup, the master outlet is typically the computer. When you shut down the computer, the strip cuts power to the monitor, external hard drives, speakers, and printer. For an entertainment center, the TV is usually the master. When the TV powers off, the gaming console, streaming box, soundbar, and AV receiver lose power completely. There are no phantom loads overnight.
Smart power strips cost between $25 and $50 and are available at most home improvement and electronics retailers. They require no apps, no hub, and no Wi-Fi, which also makes them more reliable than app-controlled alternatives for people who just want the savings without the setup.
Check and adjust your refrigerator and freezer temperature settings
The refrigerator compartment should be set between 35 and 38 degrees Fahrenheit. The freezer should be at 0 degrees. These are the ranges the FDA recommends for food safety, and they're also the most energy-efficient settings. Running either compartment colder than necessary forces the compressor to cycle more frequently, adding to your electric bill without improving food quality.
Many people have never checked what their fridge is actually set to, only adjusted the dial by feel when something seemed too warm or too cold. An inexpensive refrigerator thermometer, usually under $10, placed in the center of the refrigerator compartment will give you an accurate reading. If it's running at 30 degrees, adjusting to 36 or 37 degrees will reduce the workload on the compressor meaningfully.
Keeping the fridge reasonably full also helps. A full refrigerator holds temperature more efficiently than a nearly empty one, because the cold mass of food helps maintain temperature when the door opens. If you live alone and your fridge is mostly empty, filling jugs of water and placing them inside achieves a similar effect.
Use the microwave or toaster oven instead of the range
A standard electric oven uses between 2,000 and 5,000 watts per hour of operation. A microwave uses between 600 and 1,200 watts. A toaster or countertop convection oven falls somewhere in between, typically 1,200 to 1,800 watts. For any cooking task the microwave or countertop oven can handle as effectively as the range, using it instead produces real savings over time, particularly if you cook frequently.
In summer, running the oven adds heat to the kitchen that your air conditioning system then has to remove. That double load, paying to generate heat and then paying to remove it, makes oven use disproportionately expensive during warm months. Switching to countertop cooking in summer, or cooking in the early morning before the house warms up, reduces that compounding effect.
Reheating leftovers in the microwave instead of the oven is probably the simplest entry point. A microwave reheats food in two to four minutes. An oven reheats it in 15 to 25 minutes, plus preheat time. Over the course of a year, the difference in wattage hours between those two approaches adds up to a real number on your bill.
Run the dishwasher only with full loads and skip heated drying
The heated dry setting on a dishwasher adds electricity costs without meaningfully improving results. Opening the door at the end of the wash cycle and letting dishes air-dry accomplishes the same thing for free. Many newer dishwashers have a separate air-dry or energy-saver setting that skips the heated dry automatically. If yours doesn't, simply open the door once the wash cycle ends.
Running the dishwasher only when it's full is the other side of the same calculation. A dishwasher uses the same amount of water and roughly the same amount of electricity whether it's three-quarters full or completely full. A half-empty dishwasher run twice uses approximately twice the energy of a full dishwasher run once. If running full loads means waiting an extra day, that's the right call.
Dishwashers use somewhere between 1.5 and 4 gallons of water per cycle, and that water gets heated inside the machine in most modern models. Keeping your water heater at 120 degrees reduces the load on the dishwasher's internal heater, and using the dishwasher's eco cycle when available cuts both water use and energy per load.
Unplug phone and laptop chargers when not in use
A phone charger left plugged into the wall with no phone attached still draws a small amount of power continuously, typically 0.1 to 0.5 watts per charger. That's not much per device, but most households have several chargers plugged in at any given time: phones, tablets, laptops, earbuds, electric toothbrushes, and other small electronics. Collectively, idle chargers can add $10 to $30 per year to an electric bill, depending on how many you have and how long they sit idle.
The fix is the same for all of them: unplug the charger when the device is fully charged, or when you leave the house. A power strip with an on/off switch dedicated to a charging station lets you kill power to all of them at once. Charging everything overnight and switching off the strip when you leave for work in the morning is a habit that takes about two weeks to solidify and costs nothing to maintain.
For households with a lot of devices, a smart plug controlled by a phone app or a simple outlet timer can automate the cutoff so you don't have to think about it at all.
Check your refrigerator door seals
A worn or loose door seal on a refrigerator lets cold air escape continuously, forcing the compressor to run more often than it should. The dollar test is the standard diagnostic: close the fridge door on a dollar bill and then try to pull it out. If it slides out without resistance, the seal isn't creating sufficient contact and cold air is leaking. A proper seal should require a noticeable tug to remove the bill.
Replacement door gaskets are available through the refrigerator manufacturer and through appliance parts retailers, generally for $20 to $60 depending on the model. Installation usually involves removing a few screws or a retaining strip and snapping the new gasket into place. It takes 20 to 30 minutes. For a fridge that's been leaking cold air for months, the energy savings from a proper seal can recover that cost in a few billing cycles.
If the gasket looks intact but not sealing well, cleaning it with warm soapy water sometimes restores flexibility on older units. Petroleum jelly applied lightly to the gasket can also help it form a tighter contact with the door frame as a short-term fix while you decide whether to replace it.
Use power management settings on computers and monitors
Desktop computers and monitors are significant electricity users, particularly for households where someone works from home. A monitor that goes to sleep versus staying active saves between $15 and $40 per year per monitor, depending on the hours involved. Setting your computer to sleep after 10 to 15 minutes of inactivity, and your monitor to power off after 5 minutes, captures most of that savings automatically without requiring you to remember to shut anything down.
On Windows, these settings are in Power Options under Control Panel or Settings. On a Mac, they're in System Settings under Battery or Energy Saver. Both operating systems also let you set a schedule for the computer to sleep or shut down at a specific time, which is useful for anyone who regularly forgets to power down at the end of the workday.
Screen brightness is also worth checking. Reducing screen brightness from 100 percent to 50 to 70 percent can reduce display power use by 20 to 30 percent, which matters most on laptops where the display is often the largest power draw. Most people have their screens set brighter than they need to be for comfortable viewing, particularly in dim rooms.
Consider budget billing if your cash flow is uneven
Budget billing, also called equal payment plans or levelized billing, doesn't reduce your electricity usage or your total annual bill. What it does is average your past 12 months of usage and charge you the same amount every month, which eliminates the seasonal spikes that make winter and summer bills nearly double what you pay in mild months. Most utilities offer this at no charge, though some attach a small monthly fee worth checking before you enroll.
For people on a fixed income, or households where a $300 electricity bill in August versus $90 in March creates real cash flow stress, the predictability has genuine value. It makes the utility payment a stable line item rather than a variable one, which makes monthly budgeting easier across the board.
There are real drawbacks to understand before enrolling. Budget billing can reduce your incentive to cut usage, because the bill looks the same regardless of whether you used more electricity that month. At settlement, usually every 12 months, if your actual usage exceeded your payments, you owe the difference. That can be a jarring bill if you haven't been watching your consumption. For households where predictability genuinely matters, it's worth asking your utility about.
Replace your showerhead with a low-flow model
Water heating typically accounts for around 18 percent of household electricity consumption. A showerhead that uses 2.5 gallons per minute versus one that uses 1.8 gallons per minute means your water heater runs significantly less over a year of daily showers. WaterSense-certified showerheads use no more than 2.0 gallons per minute and are independently tested to confirm adequate water pressure and rinse performance.
The upfront cost is low: WaterSense showerheads are widely available for $15 to $50, and installation requires nothing more than a wrench and thread tape. For a household of two people who shower daily, switching from a 2.5-gallon-per-minute head to a 1.8-gallon-per-minute model reduces hot water use by roughly 25 percent per shower, compounding across 730 showers a year.
One thing to verify before replacing: the reputation for poor performance that followed early low-flow showerheads in the 1990s was largely earned. Current WaterSense certified products are tested specifically for spray force and coverage and are meaningfully better. If you tried one 15 years ago and hated it, it's worth trying again.
Keep dryer lint traps clean and check vent ducts
A clogged lint trap makes a dryer run longer to dry the same load. Longer run time means more electricity used per load. Cleaning the trap after every load is the most basic maintenance step, and the electricity savings compound across the hundreds of loads a typical household runs per year. Beyond the trap, the dryer vent duct that runs from the dryer to the exterior of the house can accumulate lint buildup over time, particularly at bends or in longer runs. A partially blocked duct restricts airflow, significantly extending drying time and increasing energy use per cycle.
The Department of Energy recommends checking and cleaning the dryer vent annually, or more often if drying times are getting noticeably longer. Flexible duct cleaning kits are available for under $20 and allow you to clear most residential duct runs without professional help. The vent should be rigid metal or flexible metallic duct rather than plastic accordion-style duct, which is more prone to crushing and lint accumulation. If yours is plastic, replacing it with metallic duct improves both efficiency and fire safety.
Drying similar fabrics together also helps. Heavy items like towels and jeans take considerably longer to dry than t-shirts and underwear. Mixing them in the same load means either the light items over-dry while the heavy ones finish, or you run a second cycle for the heavy ones. Sorting by fabric weight cuts total dryer run time over the course of a week.
Sign up for your utility's free energy audit
Most electric utilities offer free home energy audits, either as an in-person visit or as an online tool that analyzes your usage based on your billing history and answers to questions about your home. These audits identify where you're losing the most energy and which changes would have the largest impact on your specific situation. Some utilities mail free or discounted efficiency products like LED bulbs, showerheads, or outlet gaskets as part of the audit process.
To find out what your utility offers, log into your online account and look for an “energy” or “savings” section, or call customer service and ask directly. Many people aren't aware these programs exist or assume they require an HVAC contractor or expensive upgrades. Most don't. The in-person audits typically involve a technician checking insulation levels, window seals, ductwork, and appliance efficiency, and they provide a useful baseline for understanding where your money is actually going.
If your utility offers a time-of-use rate plan that you're not currently on, this is a good time to ask about that as well. Energy auditors usually know the rate plans in detail and can tell you whether switching makes sense given your usage patterns.
The total amount available here isn't negligible. Between standby power, water heater settings, lighting, cold washing, and appliance habits, most households have $300 to $500 of recoverable electricity spending that doesn't touch the thermostat at all.
