So many variables. You say this is the third month you have been in the house. I take it you aren't on an even monthly payment plan. Are you sure the meter was read each month so that the amount you payed was for the actual amount of electricity you used? I've been in places where they only read the meter every other month, and estimated the other months from previous years for that month. You may be using more electricity than the previous owner. As a minister living in a parsonage I have a whole congregation (and more specifically a council) who looks over my family's utility bills. For 25 years (with just a 2 year break where we owned our own home), I have had to deal with questions and criticisms of how much electricity etc. we use. I have 2 guys in particular right now who can't understand why our electric bill is so high (I'd love to have a $70 or even a $100 bill. The parsonage is just under a hundred years old, with 2 stories + a walk out basement and a walk up (uninsulated) attic, at least 2000 sq. ft, just on the 2 main floors. Most of the windows are the originals, and the storms are probably 25 years old. When we had some 30 to 40 mile an hour winds recently we realized by the drapes moving that the top of the door from the outside into our kitchen is warped, and we could just as well have a window cracked a couple of inches. With outside temps below 0 when the rest of the house is above 70 we cannot get the kitchen above 65. Right now we are back to being a family of 5. The guys who are the biggest complainers are both older guys with just 2 people in houses half the size of the one we are living in. One of them just replaced every window in his house. But they just can't understand why we use more electricity than they do.
