Although this fact needs triangulation and backup, I have it from a fairly reliable source that the Autzen Stadium Jumbotron costs about $20,000 per hour to run. The thing requires a lot of juice, to say the least.
Assuming seven home football games a year, and about five hours per, that means that one piece of equipment alone costs $700,000 every year. That amount could provide 12 4-year, full-ride scholarships to the UO.
