There are about 550,000 school buses in United States and Canada. Each day some 26 million children ride on school buses.
For long school buses have been the ideal candidate to go electric instead of being diesel. Eliminating the exposure of the exhaust from diesel engines would be a significant health benefit. In addition, from the electric grid perspective the battery storage in the school buses could be a valuable resource for balancing the system, thanks to school buses having defined schedules, idle during the middle of the day and parked during the summer.
