Estimated savingsAn e-bus may be 50% more expensive than a standard diesel option, and that's not including the cost of charging stations. Once over that initial speed bump, however, it's a smooth ride to savings.

Electric school buses are a cleaner, safer alternative, and they're cheaper to operate — it costs about 14 cents a mile for electricity compared to 49 cents per mile for diesel fuel, according to Blue Bird, a leading school bus manufacturer. They can also act as giant batteries to store surplus energy when not in use.
What Are The Disadvantages Of Electric School Buses? The two biggest disadvantages are cost and range. Although an electric bus is likely to save money in the long term, the initial purchase price is considerably higher.
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.
Those upfront costs for electric buses can be expensive. They vary by factors like size and battery type, but costs average about $400,000 per bus. That's more expensive than some diesel alternatives, but battery production costs are expected to decline as the market matures, according to the U.S. Department of Energy.
Since they do not use gasoline or diesel, BEBs do not produce tailpipe pollution. Thus, BEBs offer a better option than other bus technologies for reducing our greenhouse gas emissions, as well as other harmful pollutants in urban areas.
In conventional electric vehicles, there is only a fixed reduction gear attached to the motors, but in the case of a bus (or any heavy commercial vehicle), better results can be achieved by including a multi-speed gearbox.

Availability was much higher during the last 8 months with an average availability of 84.7%. The battery buses had an overall average efficiency of 2.84 kWh per mile, which equates to a fuel economy of 13.3 miles per diesel gallon equivalent (mpdge).
Additionally, commitments from California and major transit hubs, including New York City and Seattle, to go 100 percent electric with their bus fleets have led to estimates that electric buses will make up one-third of the national fleet by 2045.
Diesel school buses are already the most fuel-efficient in the industry, due to a higher BTU count compared to other fuels, providing better fuel economy and a longer operating range compared to similar-sized gasoline, propane or compressed natural gas (CNG) engines.
Fuel efficiencyFuel efficiencies used in this analysis were as follows: diesel bus: 4.82 miles per diesel gallon; diesel-hybrid bus: 5.84 miles per diesel gallon; natural gas bus: 4.47 miles per diesel gallon equivalent; and battery electric bus: 2.02 kWh per mile, which accounts for a 90 percent charging efficiency.
Expanding Bus Ranges and Declining Battery Prices Are Making Electric Buses Mainstream Electric buses today can travel anywhere between 150 miles on the lower end to 275 – 300 miles on a single charge.
TfL, however, estimates that a standard hybrid diesel-electric double-deck bus is in the region of £300,000. The latest New Routemaster with Euro VI engine costs £349,500.
