Being from North Carolina, I'm partial to Thomas Buses. They offer a fully electric school bus and have many in service already. There are also companies that will convert your existing school buses to electric for a fraction of the cost of a new bus.

Thanks,
Quote from a link of your link:
"Even with a little bit of insulation on the batteries and kind of covering up the engine compartment, to try to hold in as much heat as we could, we were still using more energy to heat the bus than we were to drive the bus.
On January 27, we had 38 below.
The bus’ efficiency that day was 3.46 kilowatts per mile. So this fall, in August-September, we were running between 1.4 and 1.7 kilowatts per mile."
As comments say batteries are better for propulsion and fuel is better for heating, as I suggested, batteries to move the bus and some sort of fuel to heat it, well at least in single digit and colder temps. In warmer temps, an efficient heat pump heater would suffice. I kinda like the idea of using propane for heat as it's cleaner than diesel and stores better, also not the possibility of things gumming up during the times they wouldn't need it and again in something as large as a bus they should have lots of areas to mount the tank. Sure propane is explosive but so is a tank full of gas!
