Compared with the traditional oil-fuelled bus, the battery electric bus only accounts for one-third of the energy cost, with no pollution and a full battery recharge can keep a vehicle running for about 300 kilometers. China had taken the lead in developing such technology in battery electric vehicles.

China would further promote electric-powered vehicles by building more recharge stations. In addition to battery-powered vehicles, experts have called for more biofuel-run buses on Beijing's roads. By 2010, China plans to plant 13 million hectares of Jatropha trees, from which 6 million tons of biodiesel can be extracted every year as a source of clean energy, according to the State Forestry Administration (SFA). Beijing becomes China's first city to use biofuel technology on a large scale.
