This is a little off topic, but
I don't see why Disney lovers (I am a HUGE Disney lover/ fanatic/ obsessive fan) have to flame Universal. I, myself, love going to Universal. I do not like it better than WDW, but every year I go to Orlando I HAVE to go to Universal. Don't know why we all just can't get along!!! 
Back to topic, you have to figure that companies such as WDW and USO get breaks on the utilities. I know that corporations around my area get breaks on the cost of utilities and such, as well as tax breaks and such. So, while I'm sure the utility bill is outrageous, I'm sure there are breaks and incentives to adjust that for them, especially WDW...if I'm not mistaken, WDW is the largest employer in FL. Universal is pretty big too.
