True, we have 110 at 15 or 20 amps. However, not all of us are bound to using electric heat for cooking. Barf! I've had it and it sucks ass. Impossible to regulate with any accuracy. We have natural gas at my home. Not sure about BTU conversion on what we have vs electric, but it still takes a bit to boil in a closed kettle. Still, we must be a patient lot, because it isn't a big deal to just turn on the stove and then go back to watching a movie or something else until the whistle blows. Then we - gasp! - get up and fill our cups.
Our family is not typical Americana though. We don't watch much broadcast TV, and even then, it is mainly a Winter activity. Summer evenings are very long in the North West so outdoor activities rule.
