   Shenzhen, Jan 1st, 2018-Shenzhen has become the world’s first city to make all its public buses, about 16,359, run on electricity. A total of 12,518 taxis, or 62. 5 percent of all the taxis in the city are electric ones. “We will replace（替换）the rest of the taxis with electric ones by 2020,” said Mr. Chen from the government.

“I have been a driver for twenty years,” said Mr. Zhang, a driver who started to drive e-buses a month ago. “We had several rounds of training and passed strict exams before we were allowed to drive the e-buses.”

The city has built 8,000 charging poles（充电柱）and 501 bus charging stations. “A bus can be fully charged within two hours and the charging poles can serve 300 buses a day at our station. Since the replacement, the bus terminal has become quiet, even as the e-buses are entering and exiting the station,” said Mr. Guan, the manager of Qinghu Bus Station.

The use of e-buses and e-taxis plays an important role in improving air quality. In a year, the e-buses use 72.9 percent less energy than the traditional ones. The e-taxis will save the energy of 119,000 tons of standard coal.

Shenzhen was one of the first 13 cities to take part in the National New-energy Vehicle Program（NNVP）. In 2017, the city spent 3.3 billion yuan on e-buses and the charging equipment. The city also encourages people to buy new-energy cars or e-cars by reducing their payment.
