We stay in a beautiful park in AZ and pay about $2500 a year. That works out to a little over $200 a month. We pay our electricity which "averages" about $100 a month. We run three AC units (I used to think overkill until we moved to AZ) and our most expensive electric bill has been $190 for a month with the three AC units, but it was in triple digits too. Winter we don't have huge bills for electric so that makes a huge difference in our averaging.
