Well the utility bill is here. The period between 12/18-1/17 we used 347 therms and 1,261 KWh's. Total cost for gas: $206.03. Total cost for electric: $188.65.
Kind of wasn't expecting the electric usage to be so high, had no more Christmas lights than last year. I suspect that had something to do with some family visiting insisting on having the can lights in the kitchen on all the time which are halogen and use about 600 watts when not dimmed. Usually make up for that February-May.
The gas usage was slightly less than I expected, I did leave it at 72 after that cold snap as I've been perfectly comfortable with that. Looking back in records going back to 2009 that 347 therms is the second most used next to January '09 which was 441 therms used, the last winter the heat was kept at 72 for that billing period. That was with the old 80% efficient furnace still in place.
