Electric buses use battery power instead of diesel fuel to move. Gas vehicles only manage to put about one fifth of the stored energy in the gas to power the wheels, whereas electric vehicles put about three fifths into the wheels, making them far more energy efficient.
An electric school bus range can be up to 250km per charge.
Two Canadian companies are making electric school buses – Lion Electric Company and Bluebird, both in Quebec.
For now, electric buses cost more than diesel buses up front, but save 60% in operating costs. Battery prices are also coming down, which will make electric buses cheaper over time.
The BC government has a $13 million line item to replace school buses as they get old. BC requires replacement at 300,000 km, so buying a new diesel bus today would lock in many years of pollution.
Children's Health Issues
Most school buses today run on diesel, which is a dirty fuel. Pollution builds up not only at bus stops but also inside the school buses themselves.
Children are especially susceptible to the adverse health effects of diesel exhaust pollutants and there is no safe level of exposure for school age children.
Diesel exhaust is a chemically complex mixture of components. It directly contributes to ambient, on-road and in-cabin concentrations of NO2, O3, and PM2.5, each of which are known to have well-established chronic and acute health
When school buses are idling the levels of air pollutants inside the bus are higher than when it is in motion. In addition, children waiting to board idling buses are exposed to high levels of pollution and even higher levels if several buses are in the same immediate area.
Calfornia Energy Commissioner Patty Monahan said,
“School buses are by far the safest way for kids to get to school. But diesel-powered buses are not safe for kids’ developing lungs, which are particularly vulnerable to harmful air pollution. Making the transition to electric school buses that don’t emit pollution provides children and their communities with cleaner air and numerous public health benefits.”
An electric bus saves about 20 tonnes of CO2 per year compared to a diesel bus.
In British Columbia the transportation sector contributes nearly forty percent of the total GHG emissions.
The Provincial Government has set a climate action target to reduce provincial GHG emissions to 40% below 2010 levels
Dominion Energy is partnering with the U.S. state of Virginia to get to 100% electric school bus fleet by 2030.
The Province of British Columbia has established a zero emissions mandate for new vehicles. By 2030 the province aims to
bring emissions from transportation down by 6 million tons. By 2040 100% of new light-duty vehicles sold will be zero emission.
BC Transit has also announced that it "will make its entire fleet of buses fully electric over the next two decades as part of its efforts to reduce carbon emissions" and "will begin buying electric-only buses...starting in 2023."
The city of Shenzhen in China has over 16,000 electric buses in its all-electric bus fleet.
The adoption of electric school buses is growing rapidly in many places. School districts in Quebec and Ontario, California, New York, Illinois and Indiana, among others, have purchased or set aside funds for battery-electric school buses.
