Huh. We're absolutely crushing this at our house. We averaged 486 watts per person in the worst month this year so far. I cheat and charge the car at work, but even when I commute every day (40 miles round trip, half-mile elevation change), it's only half our energy consumption, so we're easily below 1kw per person. I'm not including embodied carbon of stuff we buy, but still...
We did buy energy efficient everything: Induction range, hybrid heat pump water heater, spent extra on insulation, heat pump furnace, LED lights, medium-wattage desktop computer, high MPGe EV, etc.
However, we live in a normal US house with few compromises (though we don't need air conditioning or heating most days, due to the local climate).
It makes me wonder how the average US household is at 12KW. That's roughly two of our house's air conditioners running full blast, per person, 24 hours a day.
