I replaced a fridge and my electric bill went from $85 to $30 / month. Then started replacing everything that would save a penny or more and got it down to $18.00 one month (June or July). Got a new electric meter. A new meter is a trophy for your efforts. People do mess with meters and besides the thievery issue it's not necessarily safe. You'd want them to come look for leaks if you were suddenly using more, too.
