My electricity use is 5kWh/day, which you're correct actually averages to 200W. My mistake. We have gas heat/hot water. My household's _baseline_ power usage is 100W, which is probably mostly the refrigerator based on some energy meters. So you're correct, my total power consumption would only go up by 50%, but one of these dishes would double my household's idling power use.
