$66.95 a year A typical ENERGY STAR certified dehumidifier uses 343 kWh a year. At Ohio's average residential price of 19.52¢ per kWh, that is $66.95 a year, or $5.58 a month.
The tariff scales the whole rail; the model you buy is what moves the gate along it. The most efficient certified dehumidifier on this tariff draws $20.50 a year, the least efficient $548.12 — a standing difference of $527.63 a year for an appliance doing the same job.
How this is worked out
- Take the certified annual consumption for the appliance class off the EPA's ENERGY STAR register — the median of every listed model, not a wattage anyone assumed.
- Take the residential tariff off the EIA's Electric Power Monthly, table 5.6.A. Here that is Ohio's residential average, 19.52¢ per kWh.
- Multiply, then divide by 100 to come out of cents. Nothing is rounded before this line.
- Derive the rest of the schedule from that one figure: ÷ 12 monthly, ÷ 365 daily, × 10 for a ten-year life.
- Overwrite the tariff terminal with the rate printed on your own bill and the register re-reads. The certified consumption does not move — that is the half of the sum nobody gets to opinion their way out of.

About $66.95 a year — $5.58 a month — for a typical ENERGY STAR certified dehumidifier using 343 kWh annually, at Ohio's average residential rate of 19.52¢ per kWh.
How much electricity does a dehumidifier use?
Certified models range from 105 to 2,808 kWh a year, with a median of 343 kWh. That spread means the model you choose changes the running cost by $527.63 a year in Ohio.
Is that more or less than the rest of the country?

Will my bill actually go up by this much?
Only roughly. This is the certified test figure at your state's average price. Your own tariff, how heavily you use the appliance, and its age all move the real number. Older non-certified appliances often use considerably more.
