Really??
In the summer, around $175, and in the winter months around $100--of course this is Arizona we're talking about and I hear AZ Public Service is one of the most expensive in the nation.
II live in an 800 sq. ft apartment with central heating and air, so all I have to pay for is running the fan. Plus I'm only home about 2 weeks out of every month, and I pretty much live on my boat on weekends in the summer.
