So far, wind energy makes up just 0.4 percent of China's electricity supply. However, Beijing is building the world's biggest wind power project, although paradoxically, adding wind power in China also means adding new polluting coal-fired power stations.
The blades of a 20-story wind turbine slicing and chopping through the air are the only noise out here in China's western Gansu province. More than 100 Chinese-made turbines dot the bleak landscape. They call this the "Three Gorges on the Land," drawing parallels to China's gigantic hydroelectric project.

Nature is unpredictable: Sometimes there is no wind; other times, it's so strong the turbines have to be shut down. Because China's transmission power grid can't cope with the intermittent nature of wind, the government is adding back-up coal-fired power plants along with wind power to level out those peaks and troughs.
In Jiuquan, new coal-fired power plants with 13.6 million kilowatts of installed capacity — the same amount of energy generated by Chile in 2009 — will be added by 2020. The need to add baseload coal-fired power plants has the effect of reducing the clean benefits of wind power.
