Electric school buses are batteries for the grid

Utility companies are helping cash-strapped school districts replace diesel buses with electric ones that have a secondary purpose: helping to manage electricity demand.

Why it matters: Electric buses are cleaner, but cost about three times more. Using them for energy storage can help close that cost gap and smooth out energy demand on the electric grid.

What’s happening: Less than 1% of America’s 480,000 school buses are electric today, but that’s beginning to change.
