I'm natural gas and electric. Granted, I'm not home a whole lot and heat it from 60 to 67 for a couple of hours a day average. I'm very conservative with utility consumption and am at 1500 sq/ft but a high bill for all my energy needs has not been over 75 bucks a month this winter.
I'll count my blessings I suppose.
*** ... now that's pretty darn good.
With a month of constant -40's my last bills totalled $250.
