Yeah with the cost of just about anything you will probably be spending more than the electricity. The only way the electricity is going to be more than the object that creates that creates the electricity is if you're working with some nice big HPS lights. Look at Ralph Davis's setup he has a 1500 dollar electric bill every month, now imagine how many racks he has. That 1500 dollars doesn't seem so high.
