Battery-powered electric buses are 2.5 times cleaner in terms of lifecycle emissions than diesel buses, according to a study by UCS. Buses on the US West Coast are the cleanest because of the use of hydro, wind and solar power to generate the electric buses' electricity, while Midwest buses have higher emissions because of the use of coal power to generate electricity, although they are still greener than diesel buses. The disposal of batteries continues to be an issue. More than 85 US transport agencies have introduced electric buses to their fleet.
