Uh what information would that be? You use more electricity when you are home and less when you are away at work. You gotta realize that your life is pretty mundane and boring and nobody would really want to analyze it. There are a lot more important issues to be concerned with and the government liberals are probably happy that people are taking the time to concern themselves with this issue.
I thought the same thing, until I started reading a bit about smart meters. They don't call them 'smart' for no reason. They collect a whole lot more metric data about you than you'd be comfortable with, if you knew.
