2500 sq ft 2 story, 3 bed, 2.5 bath, house.  Just myself (divorce).  Electric hot water heater, gas fireplace, electric dryer, gas furnace, a/c.  Thermostat in winter is set to 65, summer 72.  If I remember correctly, the highest bill this winter was in the $150 range.  Previous summer was near $100.  Both were very mild in comparison to other years. 
  
Actually thinking about solar panels.
