What Oregon homes use
EIA's 2020 residential survey found 3,585 kWh a year across 181 sampled homes that run one, 1.44× the national 2,484 kWh. The middle half spans 975 kWh to 4,727 kWh, so electric space heating varies by 3,752 kWh between one household and another.
All electricity used for space heating, including the furnace or heat-pump compressor and the air handler that moves the heat around the house. That average covers homes heated with electricity — 60% of homes here.
That makes electric space heating about 32% of the electricity an Oregon home uses. The remaining 7,548 kWh is what electric space heating is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
