What New Jersey homes use
EIA's 2020 residential survey found 147 kWh a year across 132 sampled homes that run one, near the national 139 kWh. The middle half spans 60 kWh to 195 kWh, so a humidifier varies by 135 kWh between one household and another.
Portable and whole-home humidifiers. That average covers homes with a humidifier — 27% of homes here.
That makes a humidifier about 2% of the electricity a New Jersey home uses. The remaining 8,158 kWh is what a humidifier is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
