Shenzhen has been working toward this goal for a while. It already has 14,000 electric buses on the street, with only has a few hundred diesel-powered buses left to replace. They will be decommissioned over the last two months of the year. BYD is in charge of providing 80% of the electric buses for the city. It is also heavily vested in electric vehicles (EV), leads the world-leading Chinese EV market, and has introduced its electric bus all over the world, including in Long Beach, California, where we were privileged enough to take its maiden ride.
BYD started the Shenzhen pilot test in 2011. In six years, the giant city (population 11.9 million) managed to implement a complete switch. So, what is taking us so long in the West?
