Again, what you're stating is the minimum of the distribution, not near the mean. I can sometimes do $100 in utilities but frequently during the winter, I have to pay for >$100 per month for power alone. I rent so I can't wait for the landlord to read their maintenance requests and patch up the holes.

I once cut my power bill during the winter by sleeping in a closet with a space heater. Other times, I hung out in coffee shops to avoid having to be home and having to turn on the heater. May be that's the kind of living you imagine that isn't crazy, but I don't imagine everyone is willing to live like that.
