Chase Field

This weekend was my first game at Chase Field. Being from Los Angeles the only stadium I have ever seen is Dodger stadium, which doesn't even compare with Chase Field. Although rooting against the home team I couldn't have had a better time. The weather was perfect the game was entertaining, however, the one thing that kept my mind very busy during the game was- how much the air conditioning bills must be during the summer? Yes this consumed my thoughts through a great portion of the game.
So I knew I had to google this and get some more information- the air conditioning inside of Chase Field for one game in equivalent of air conditioning for more than 2,500 homes in Arizona. However, I thought the cooling system was for the entire park but in reality according to ballparktour.com the system brings the temperature down by 30 degrees in 3 hours and it only cools the seating areas.  According to google on average a home in Phoenix could have a bill of $200 so multiply that by 2,500 its almost $500,000 per game to run the air condition the stadium during summer games. If you consider that with ticket prices etc. makes you really wonder if its worth it..I love random tid bits like that. I also just read that it cost $2 in electricity to close or open the 9 million pound roof at Chase Field.
