The nearest major city to me has had electric buses since 1940. There are power cables overhead and poles that link the bus to the grid. No need for expensive flammable batteries that need extensive charging.

As long as they're being purchased as a replacement for buses that are either at the end of their life or being donated to smaller communities, then sure. This said from the perspective of an American whose city, state and federal governments refuse to fund the public transit that we already have. (╥_╥)
