Running a 1,500-watt space heater 8 hours a day in Alabama costs about $60.27 a month — $0.25 an hour on full power at Alabama's average 16.51¢/kWh.
At 16.51¢/kWh — Alabama average, Jan–Aug 2026 (EIA). That is 9% below the U.S. average of 18.19¢.
| Period | kWh | Cost |
|---|---|---|
| Per hour of use | 1.5 | $0.25 |
| Per day | 12 | $1.98 |
| Per month | 365 | $60.27 |
| Per season (5 mo) | 1,825 | $301 |
Normal mean temperature (NOAA, population-weighted). Highlighted months average below 60°F.
| Heat source | $ per million Btu | This much heat |
|---|---|---|
| Gas furnace, 95% AFUE | $17.84 | $22.22 |
| Heat pump (ENERGY STAR avg) | $19.56 | $24.36 |
| Gas furnace, 80% AFUE | $21.19 | $26.39 |
| Propane furnace, 95% AFUE | $41.13 | $51.22 |
| Space heater / baseboard | $48.39 | $60.27 |
In Alabama resistance heat costs 2.7× as much as gas heat from a 95% furnace. A space heater only saves money when it lets you turn the whole-house thermostat down several degrees and heat just the room you're in. A heat pump delivers the same heat for about $24.36 a month.
| Heater | Per hour | 8 h/day, month | 24 h/day, month | Season (5 mo, 8 h) |
|---|---|---|---|---|
| 750 W | $0.12 | $30.13 | $90.40 | $151 |
| 900 W | $0.15 | $36.16 | $108.48 | $181 |
| 1,500 W | $0.25 | $60.27 | $180.80 | $301 |
1.5 kW × 8 h = 12 kWh a day; × 30.42 days = 365 kWh a month; × 16.51¢ (Alabama average, Jan–Aug 2026, EIA) = $60.27.
Because resistance heat costs 2.7× as much as gas heat in Alabama, a space heater saves money only if it lets you turn the whole-house thermostat down and heat just the room you're in. If your home heats with electric baseboards or furnace strips, a space heater costs the same per Btu — the saving comes only from heating fewer rooms.
The average Alabama home used 1,152 kWh a month in 2025 (EIA); this heater adds 32% to that while it runs.
