Me? An Energy Hog?

So I got my electric bill today. I realize that to Big A, $144 is a good electric bill. For me, it's about twice as much as normal. Now, I realize that this is a new house for us, but I have a propane dryer, a propane stove, and my water heater is run off of kerosene, which is what we use for heat. My washing machine is only 1 year old, and it's a front loader. I have no idea how old the fridge is here. My stove and my microwave are brand new. We have one of those blow up pools with a filter, but it has rarely been on this month because it's been too cold. I bought a dehumidifier at the beginning of the month because we were getting mold in the basement, but that's an energy star appliance. We shut our AC off 2 weeks ago. Could it be just the lights and the refrigerator. We also have a small dorm fridge in our garage for extra sodas and stuff, but we had that at the old house and it never cost us much there. So what could be the difference?
