Yea, that is pretty low for utilities. Quicker showers, and don't heat dry dishes when you use dishwasher (if it has that option). Get some window inslation kits for the windows, which will help with heating costs. Also get a door draft stopper for your front door (there are a bunch of DIY's to make one yourself or just roll up an old towel and keep it by the door.
