How many kWh does an electric school bus use?

Depending on the size of the bus, battery packs can range in size from 90 kilowatt-hours (kWh) to over 300kWh, with many manufacturers offering multiple battery pack size options for each bus type to meet the driving range requirements of a given fleet. Electric school buses will soon be deployed across 36 states.

It's cheaper to run and maintain an electric bus. Fueling a bus with electricity is only about a third of the cost of fueling it with gas, which saves a considerable amount of money over time. Electric buses also have fewer regular maintenance costs—because they don't run on fuel, there's no need for oil changes.
