Even though stadiums are only used periodically for games, the reality is with tens of thousands of fans at games massive water, trash, sewage, and energy usage can leave a huge carbon footprint. Owen Glubiak reported about the Cowboys stadium in an article for the EE Times online and he cites, “the stadium averaged about $200,000 a month in utility bills” which comes to about “2,036,560 kWh per month or roughly 24,439,918 kWh per year”. He goes on to reveal that it is equivalent to the same amount of energy that the entire city of Santa Monica uses per year.
