Those 1,532 kWh are billed at 7.0¢–9.9¢, against a 9.6¢ whole-bill average on the median plan: they land in the last tier the household reaches, so the average rate understates them by up to 0.2¢ per kWh.
What Ohio homes use
EIA's 2020 residential survey found 1,532 kWh a year across 318 sampled homes that run one, 34% under the national 2,318 kWh. The middle half spans 730 kWh to 2,113 kWh, so air conditioning varies by 1,383 kWh between one household and another.
All electricity used for cooling — central systems, heat pumps in cooling mode, and window or wall units — plus the air handler that runs with them. That average covers homes with air conditioning — 94% of homes here.
That makes air conditioning about 15% of the electricity an Ohio home uses. The remaining 8,746 kWh is what air conditioning is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
