The parking and transportation department uses 24 compressed natural gas vehicles, 23 ethanol-capable vehicles, and 42 electric vehicles. The university’s vehicle alternative fuels policy states that any new vehicles purchased must be capable of using an alternative fuel, and any small utility vehicles purchased must be electrically powered. The student association offers a free bicycle library that restores used bicycles and checks them out to students to use for the semester. The university is in the process of constructing a network of bicycling, walking, and jogging trails, and has formed a committee to help enhance the bicycle-friendly nature of the campus.
