I just got hit with my second $900 energy bill, and that was AFTER I took pretty significant steps to curb it. Two zone gas system, and I just upgraded zone 1 for more efficiency. The gas side of the bill was $465 averaging $14/day. When we first moved in 7 years ago, it was $270 total energy MAX, gas and kwh.
I'm not sure what else to do to get it lower, because nothing actually seems to work.
