Despite all the economic hurdles of the last year, districts are still finding ways to upgrade their school busses to better, cleaner options. School Bus Fleet recently reported on a California district, Fairfield-Suisun Unified School District in Napa County, which received a state grant allowing them to purchase two propane-powered buses.
At this point, it's almost inarguable that diesel-powered buses need to go away. The questions are, how to make it happen, and which alt-fuel to switch to? Currently, the major contenders for eco-friendly school buses are either propane or electric.
