These frozen smoke belchers are Minnesota school buses that were set for a retrofit with diesel engines in 2012. New evidence, however, from a small town in Colorado suggests that another retrofit is needed-to electric motors and batteries.

That's because the West Grand School District is finding that in the frigid winter temps of -30°F, their electric buses outperformed their diesel-powered ones, both in running costs and reliability.

EV skeptics and critics are quick to mention the reduced range of a battery pack when exposed to such brutal temperatures, but no Minnesotan or Coloradoan needs reminding about those especially cold mornings when the car won't start.

Kremmling Colorado is one of the coldest towns in the country, and the school district that encompasses this hamlet of 1,500 people was able to begin using an electric bus in their fleet starting in 2020 thanks to grants from the EPA, along with the Colorado Department of Public Health and Environment (CDPHE).

"What we are seeing is that these buses are doing great in cold weather they still maintain a battery charge even when it's cold," said Environmental Protection Agency (EPA) representative, Casey Becker.

"It averages 26 cents per mile and the diesel buses, just for fuel not including oil changes, filters, lubes, is 58 cents per mile," said West Grand County School District Director of Transportation, Bethany Aurin.

Becker told Fox 9 News that there will be a total of 49 electric school buses heading to nine Colorado School Districts, including four in Summit County and three in Steamboat Springs.
