Cost to run a space heater in Nebraska
At Nebraska’s average residential rate of 13.59¢ per kWh, a space heater drawing 1500W for 8 hours a day costs about $49.64 a month. Change the numbers below to match how you actually use yours.
Winters in Nebraska are cold enough that a space heater will carry real load from late autumn through early spring, then sit idle for the rest of the year. Spreading the annual cost evenly across twelve months therefore flatters the summer months and understates the winter bill.

Why the cost differs in Nebraska
Nebraska has the 4th cheapest residential electricity of the 51 US states and territories we track, at 13.59¢ per kWh against a national average of 18.44¢. That is -26.3% compared with the national figure. Nebraska is the only state served entirely by public power, with no investor-owned utilities anywhere in it. That means no shareholder returns are built into rates, which is a structural reason its electricity is cheap rather than a temporary market condition. Retail choice does not exist. Hot summers and cold winters both drive meaningful load.
For this appliance specifically, the difference works out to a saving of $212 a year against what the same space heater would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $2,278 a year; in Idaho it would cost $541. That spread of $1,737 is entirely down to location.
At Nebraska's rate this single space heater accounts for roughly 42% of a typical household's entire annual electricity bill. It is not a rounding error on your statement - it is one of the largest single line items in it.
Electricity in Nebraska is cheap by national standards, which cuts both ways: running this space heater costs less than it would almost anywhere else, but the payback period on an efficiency upgrade is correspondingly longer. Replacing a working unit purely to save energy is harder to justify here.
Nebraska is served by public power rather than investor-owned utilities, so there is no supplier to shop between. The published average is close to what most households actually pay.

About running a space heater
Electric resistance heaters are 100% efficient at converting electricity to heat, which sounds good but is misleading: a heat pump moves two to four times more heat per unit of electricity. A 1,500W space heater is the single most expensive plug-in load in most homes, and running one continuously through a winter is what usually causes the "why is my bill so high" moment.
What actually changes the cost
- At typical use this is a major load - around 4,380 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
- Insulation and air sealing reduce runtime, which lowers cost more reliably than adjusting the thermostat by a degree.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
1500W ÷ 1000 × 8h = 12.000 kWh/day × 13.59¢ = $1.631 per day
One honest caveat: Nebraska’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about space heater running costs
How many watts does a space heater use?
A typical space heater draws about 1500 watts while running, with most models falling between 750W and 1500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a space heater use per day?
At around 8 hours of use a day and a 100% duty cycle, that works out to roughly 12 kWh per day, or about 360 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same space heater, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a space heater at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
