Bus fleet electrification by region 2018
Electric buses accounted for some 14 percent of China's bus fleet. The country is a world leader for electromobility, and more cities are replacing fleets with battery power. The Chinese region of Shenzhen operates a fully electric bus fleet, the first in the world. In 2018, the mega city had a fleet of some 16,000 electric buses. Although investment into electric public transport exists across Europe, budgets restrict the speed at which diesel engines can be phased out. In the United States, only 0.03 percent of buses were electric in 2018.
