If you're using electric baseboard heaters, then electricity is a concern, but most people are using natural gas.
In the summer, air conditioning is subjective. Just because I turn mine on, you may decide it's cool enough.
The bulk of electric bills are for appliances. How often do you run your dryer. How often do you cook using the electric stove or bake. None of this has anything to do with the size of your house.
