was total electric. I can't imagine that kind of bill! I did run the little electric heater in the bedroom during the sub zero temps a couple weeks ago because I was freezing! I can't do that too much if the electric bill goes sky high. I hate freezing! The $500 propane was actually cheaper because it was for over 7 months. Should clarify it is Indiana/Michigan Power (electric) that we have. I can't complain about it since we used the electric heaters and put our bathrobes in the dryer for a few minutes on several nights to get them warm during the really cold stuff and it was still only $213 for January. But some of the posts about $500-700 have me scared! I would faint if I got a $500 or higher light bill! The data centers are scaring me if they come in because I can't imagine the light bills!
