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.


When summing up 2017, it should be noticed, that it was the first year, when annual worldwide sales of EVs (electric vehicles, both battery only and plug-in hybrid electric vehicles) exceeded 1 million vehicles.

The exact numbers are not yet available, but it looks to be well over 1.1 million EVs. By far most of the EVs, about 580,000 were sold in China. 200,000 EVs were sold in United States, and about 305,000 were sold in Europe.


In May 584 000 cars and 935 000 light duty vehicles were sold in the United States. Only 1.1 %, or 16,788 to be precise, of these vehicles were electric (EV) or plug-in electric (PEV)s. Not a big number, but in terms of battery storage the numbers get more significant.

For the month of May, the total amount of battery storage in the EVs and PEVs cars is 570 MWh. In comparison, according to GTM Research/ESA US Energy Storage Monitor, for all the first quarter this year 234 MWh of stationary “utility scale” electric storage was added and another 13 MWh of distributed storage was installed behind the electric meter.
