December was colder than usual, by about 25% — 701 Heating Degree Days (HDD) versus 505 HDD last year. This doesn't quite account for the 50% increase in natural gas usage year-over-year, however — that would be my daughter home for college for most of December. I seem to recall that the TV was on most of the time as well, which might well account for the 15% increase in electricity use. Of course, running the Christmas lights didn't help, either. All in all, our utility bills for December came to $295. Ouch!
