Cars
make our lives more convenient. But they can also be a problem. For example, fossil
fuel(化石燃料) cars mainly cause air pollution.
To
improve the environment, many countries are developing electric vehicles (EVs,电动车). Among them, China is taking a leading role and has created the
world's largest EV market.
Last
year, over 40 percent of the 753,000 EVs sold in the world were sold in China,
more than twice as many as the number sold in the United States.
"Filling
up a fossil fuel car with gas(汽油) is more expensive
than charging( 充电) an electric car，" said Wu Hao，who bought an electric
car this year.
However,
there are still some problems. It can be hard to find charging piles(充电桩) and the cars can't go far before needing to be recharged.
Some
of these problems are being solved. In 2014，China had
31,000 charging piles. Now China has the world's largest EV charging network,
with more than 167, 000 charging piles in total.
Developing
EVs is one of many efforts that China has made to cut down pressure on its environment
after the government promised to stop increases in carbon dioxide emissions(二氧化碳排放量) by 2030.
"As
China goes, so will the world's car industry," The Wall Street Journal
said. China has taken a leading role in the world's electric vehicle industry.
