You can't buy one at your local car dealer, but electric transit buses have a significant role to play in reducing vehicular emissions and expanding the spread of electric-vehicle technology.

Two companies have a majority of the U.S. market for electric buses, which is growing quickly if perhaps more quietly than that for electric cars.

The U.S. company Proterra has 60 percent of the market for such vehicles, and now it has a new backer.

Indeed, the economics of operating huge, heavy transit buses that cover hundreds of thousands of miles on grid electricity are in some ways more favorable than the savings that accrue to individual car buyers in the retail market.

By some estimates, the next 10 years could see a majority of the world's urban transit buses switch from diesel fuel to grid power—with savings on running costs as well as major emission reductions the reason.
