$200 is normal and it has also been an extra cold winter. I do residential energy efficiency, spending $2-$3k to insulate and more importantly air seal the home will make a drastic impact on utility bills. In our 3 floor home we never go above $150 and the electric bills in the summer are under $150. A programmble thermostat is a cheap investment that can make a good impact as well. Our home goes down to 60 during the day and returns to 68 before I walk in the door.
