Air pollution is a severe problem in Taiyuan. Vehicle emissions account for about 16% of particulate PM2.5 and 14% of PM10.
In 2015, the total installed power capacity of Taiyuan was 7.33 million kW, with a total generation capacity of 21.2 billion kWh. If all the city’s 2,501 buses, 8,292 taxis and 22,385 logistics vehicles were replaced for electric vehicles, annual electricity consumption would account for 9.95% of the 2015 total power generation. Taiyuan can supply enough electricity to power all electric vehicles by effectively managing local resources.
By August 2016, Taiyuan has successfully replaced all of its conventional taxis with electric vehicles in an effort to reduce dependency on fossil fuels and cut emissions within the city. The project has seen they deployment of 8,292 electric vehicles and is estimated to have achieved an annual reduction in CO2 of 222,000 tons. Since full implementation in August, the city estimates a resulting emissions reduction of over 8,000 tons of CO2.
Since starting the project, Taiyuan have save around US$7.95 million in operating costs. The city-wide transition to electric vehicles has also improved air quality, providing a healthier and more sustainable environment for city dwellers. The new vehicles are quiet, comfortable and environmentally friendly, making them well received by citizens, who are volunteering to promote the new cars. This helps to foster beneficial development, and engagement with, the renewable energy industry in the city.
Taiyuan predicts that over 8 service years, the total emissions reduction for the whole fleet of electric vehicles will reach 1.78 tons. 21,176 tons of CO2, 2,451 tons of Hydrocarbon, and 3,478 tons of NOx will be reduced per year, accounting for 12.15%, 12.14%, and 12.14% of total emissions respectively. Additionally, across an 8-year service period, total savings of USD$167 million have been forecasted.
