"I don't have to worry about $6,000 worth of utilities to run a house," said Gil Lobell, a current zero-net home dweller moving his family into a larger house in the new development. "I can use that money for other things, so we go on vacations because I'm not spending money on utilities. I don't worry about oil bills. I don't worry about electric bills. I don't worry about gas bills."
