Trip Sheet: Pursuit of Clean School Buses Requires Time, Money, and Commitment

The noble effort of transitioning from diesel-powered school buses to cleaner counterparts is a commendable goal in pursuit of a greener and more sustainable future.

However, the scope of this endeavor is vast, as there are approximately 480,000 school buses in the United States alone. While the EPA's Clean School Bus Program has allocated $5 billion and set a timeline of five years to distribute this money via competitive grants and rebates, it is essential to recognize that this ambitious initiative requires a far greater investment of time and resources.

Replacing every diesel school bus with an electric alternative demands substantial funding and an extended period, considering the scale of production, infrastructure development, and logistical challenges associated with such a colossal transformation.

The Projected Cost of a U.S. Electric School Bus Fleet

To calculate the cost of replacing all the school buses in the United States with electric alternatives, we can multiply the number of buses by the cost of one electric bus:

• Cost per electric bus: $375,000 (approximate).
• Number of school buses in the United States: 480,000 (approximate).
• Total cost = Cost per electric bus * Number of school buses.
• Total cost = $375,000 * 480,000.
• Total cost = $180,000,000,000.

So, it would cost about $180 billion to replace all the school buses in the United States with electric alternatives.

Now let's calculate the time it would take to complete their replacement based on production times:

Time to produce one electric bus: 6-8 months (depending on lead times).

To estimate the time to replace all the buses, let's assume the production time is eight months for each bus (the maximum estimate). We also need to consider that the manufacturer can produce multiple buses simultaneously. Let's assume they can produce 100 buses at a time.

• Number of buses produced in 8 months: 100.
• Total time to replace all the buses = (Number of school buses) / (Number of buses produced in 8 months).
• Total time = 480,000 / 100.
• Total time = 4,800 months.
• Converting months to years: Total time in years = Total time (in months) / 12.
• Total time in years = 4,800 / 12.
• Total time in years = 400 years.

Based on these calculations, it would take about four centuries to complete the replacement of all the school buses in the United States with electric alternatives. It’s a rough estimate, though, and doesn’t account for factors such as scaled-up production capacity or potential advancements in production techniques or improved supply chain that could reduce production time.

[NOTE: Calculations suggest that it might take about the same amount of time to replace diesel buses with propane-powered vehicles, but it would cost about $47 billion – still much more than the $5 billion offered by the federal government, but about 26% the cost of replacing with electric.]

Are the Price Tag and the Challenge Worth the Effort?

While the EPA's Clean School Bus Program is a step in the right direction, the complete replacement of diesel school buses with cleaner alternatives will require significantly more time and financial investment than the allotted five years and $5 billion. Achieving this goal necessitates long-term commitment and substantial resources to create a sustainable and eco-friendly transportation system for our schools.

But is it worth it? Should we bother?

I think so. Sure, it’s challenging, but moving to electric buses (for example) offers several benefits, including reduced greenhouse gas emissions, improved air quality, and quieter operation.

It also makes a point to future generations, emphasizing the importance of sustainable transportation practices. While the task might be daunting, taking action to minimize our environmental impact and prioritize the well-being of our communities is a responsibility worth embracing.
