First Energy Bill

[MattVollet]

Hey everyone, I moved from Ohio to Orlando, Florida just over a month ago into a my first 750 Square foot apartment on the first floor. We just got out first energy bill and it is $250 dollars (not counting the start-up costs) and I'm wondering if this could possibly be correct at all. I have a Panasonic 50PZ85U (calibrated for the new apartment), PS3, X360, Wii, HD-DVR and 5.1 Surround (I don't leave any of this on when i'm not using it). We also have 1 desktop computer, 2 laptops and then another 30-something inch LG Super Slim that is almost never on. The Panasonic TV is maybe on for 4 hours a day, on a day with nothing to do. We turn the lights off when we leave and aren't using them and we keep the air on 75 when inside and 80 when out.
Still, 250 Dollars for an electric bill seems ridiculous- but I wasnt sure if the Plasma was pushing me into another dimension of energy costs.

Any help would be appreciated... I just need to know if this is normal before my Fiance kicks my butt!

Thanks everyone
