TL;DR The fastest way to lower electric bill spending is to fix the two biggest loads: heating and cooling, then water heating. Set the thermostat back 7–10 °F for eight hours a day, drop the water heater to 120 °F, and seal the worst air leaks. Most of these steps cost nothing.
Your bill is not one number. It’s the sum of many small, invisible decisions: a thermostat left at one comfortable setting all day, a second fridge humming in the garage, a dryer running a heated cycle for a load that could have air-dried. You don’t need to fix all of them.
The trick is order. Spend your effort where the electricity actually goes, and a few changes move the total far more than a house full of smart plugs. Below are 12 ways to lower electric bill spending, starting with the biggest uses and ending with the cheap wins.

First, understand where your electricity goes
The U.S. Energy Information Administration (EIA) puts average household electricity use at roughly 10,500 kWh a year, and it is not spread evenly. Three uses dominate:
- Air conditioning: about 19% of residential electricity use
- Space heating: about 12%
- Water heating: about 12%
Lighting and refrigerators come next, and every other appliance splits the remainder. That ranking is your roadmap: cooling and heating together account for nearly a third of all electricity in U.S. homes, so a small change there outweighs a heroic change at the toaster.
💡 Info Your exact split depends on climate, home size, and whether you heat with gas or electricity. A home with gas heating will see water heating and appliances at the top instead. Read your own meter for a week before spending money on upgrades.
The 12 ways, ranked by return
I’ve grouped these by cost. Do the free steps first; they cover most of the available savings.
Free: no-spend fixes you can start today
1. Reset the thermostat on a schedule. This is the highest-value free change in the house. The Department of Energy’s guidance equates a setback of 7–10 °F from your normal setting for eight hours a day with savings of roughly 10% on heating. Turn it down (or up, in summer) when the house is empty and while you sleep, and let the house drift back before you return.
2. Set the water heater to 120 °F. Water heating is about 12% of household electricity. If your tank is set high “just in case,” you’re paying to store heat you never use. Many manufacturers ship tanks at 140 °F. Lower it and check the manual for the safe minimum for your model.
3. Wash laundry in cold water and skip the heated dry. Heating the water is the biggest energy cost of a wash cycle, and the dryer’s heating element is the biggest cost of drying. Two dials: cold wash, and either a lower dry setting or a line.
4. Run full loads, and run them off-peak. A half-full dishwasher uses almost the same energy as a full one. If your utility offers time-of-use rates, shifting laundry and dishwashing to cheaper hours cuts the price per kWh even when the kWh stay the same.
5. Air-dry dishes. Turn off the heated-dry setting on the dishwasher. It costs nothing to change and it’s a daily saving rather than a weekly one.
6. Unplug what idles. Televisions, consoles, chargers, and desktop setups draw power in standby. A power strip with a switch makes this a one-action habit.
Low cost: under about $50
7. Seal the obvious leaks. Warm air escaping around doors and windows makes your heating system work harder to hold a temperature you’ve already paid for. Weatherstripping and door sweeps are cheap and install in an evening.
8. Swap to LEDs. The EPA notes that ENERGY STAR-certified bulbs use up to 90% less energy than incandescent bulbs for the same light. Start with the five fixtures you actually have on every evening.
9. Change the HVAC filter. A clogged filter restricts airflow and forces the blower to run longer. Check it monthly in peak season and replace it when it’s visibly grey.
10. Use fans instead of the thermostat. A ceiling fan doesn’t cool air — it cools you. That means you can raise the setting a few degrees and stay comfortable, which is where the savings live.
Larger investments
11. Buy a smart or programmable thermostat. Worth it if your household is out at predictable hours and you’d otherwise never touch the dial. It is not worth it if you already set back manually.
12. Plan big appliances on efficiency, not features. When a fridge, water heater, or air conditioner dies, look for the ENERGY STAR label and size the unit to the room. An oversized air conditioner cools fast and then cycles, which dehumidifies poorly and wastes energy.
⚠️ Warning Do not touch the thermostat if someone in the household is frail, very young, or has a medical condition that makes temperature swings risky. Comfort and safety come before savings.
What usually explains a sudden jump
If your bill doubled rather than crept up, the cause is probably one of four things, and none of them are “the rate went up” alone.
- A season change. Cooling is the largest electricity use in U.S. homes, so the first hot month is always the biggest jump.
- A failing appliance. A fridge with a broken seal, or a water heater with a leaking element, runs almost constantly.
- A rate or fee change. Check the kWh line and the rate line separately. Usage flat plus rate up is a tariff story, not a habit story.
- A billing or meter error. Estimates, a new meter, or an unpaid balance rolled in. Call before assuming.
A useful trick: compare the same month last year, not last month. Weather distorts month-to-month comparisons badly.
Where to find the money for upgrades
Before you buy anything, check what your utility or state already offers. Rebates and incentives for insulation, heat pumps, and appliances can cover a meaningful share of a larger project, and the DOE’s Energy Savings Hub is the starting point for household rebate programs in the U.S.
The same logic applies to the smaller jobs: many utilities give away LED bulbs, smart power strips, or discounted thermostats. Ask before you pay retail.
The short version
Learning how to lower your electric bill is mostly a question of sequence, not sacrifice. Set the thermostat back on a schedule, turn the water heater down, wash cold, seal the drafts, and change the filter. That combination costs almost nothing and targets the three biggest uses in the average home.
If something in the house is behaving oddly rather than just costing money, start elsewhere: a running toilet wastes water every minute, and a clogged drain is cheaper to clear early than to repair later. For the wider set of household fixes, the Home Fixes & Life Hacks guide collects the rest in one place — including the maintenance jobs that quietly inflate both your water and power bills.
Frequently asked questions
What is the fastest way to lower an electric bill?
The thermostat. Setting it back 7–10 °F for eight hours a day is free, takes a minute, and targets the largest electricity use in most homes. The DOE’s guidance puts the heating saving in the region of 10%.
Does turning off lights actually save much?
Less than heating and cooling, but more than most people expect when it’s the five fixtures used every evening. Depending on where you live, the bigger win in that same five minutes is replacing those bulbs with LEDs rather than switching them off.
Why did my electric bill go up when I used less?
Check three lines separately: kWh used, the rate per kWh, and the fixed charges or fees. Usage can fall while a rate increase, a new fee, or a billing adjustment raises the total.
Is a smart thermostat worth the money?
It depends on your household, not the thermostat. If nobody is home at predictable hours and you’d never adjust the dial yourself, it will usually pay for itself. If you already set back manually, it mostly adds convenience.
Should I switch to a cheaper electricity plan?
Only compare the full price per kWh, including the supply charge and any early-termination fee, and only if you’re willing to track the contract end date. A lower headline rate on a variable plan can cost more than a flat one when prices move.
