I dunno about $600. $200-300 was a typical bill for an older detached 3BR when I was in college. split several ways of course. it wouldn't surprise me if people with significantly larger (and poorly insulated) houses paid a lot more, but that wouldn't be common. AFAIK, the vast majority of an energy bill typically comes from heating and cooling. appliances don't contribute that much. in my current 1BR, with great insulation and neighbors above, below, and on both sides, I too pay about $60 for utilities.
