How does Zhangjiakou's wind power light up Olympic venues?
The electricity that illuminates the Winter Olympic venues day and night, and makes the Beijing Winter Olympics the greenest Games, along with the hydrogen that powers the 1,200 vehicles shuttling among the Olympic village and different stadiums and stages - the largest use of hydrogen-powered vehicles in Olympic history, both come from Zhangjiakou, a city in North China's Hebei Province that is 180 kilometers from Beijing and also the co-host city for the Games.
