Dry Beijing barely gets any winter precipitation, making this year's Winter Games the first to rely almost entirely on artificial snow. Organizers are touting the event's green credentials, but experts do worry about the environmental impact of such a massive snowmaking operation given the huge amounts of water and electricity it takes.
At Yanqing north of Beijing, where organizers built the alpine ski venue from scratch, the slopes stand out as ribbons of white contrasting starkly against the surrounding brown hillsides. Snowmakers have also been deployed farther north in Zhangjiakou, which is hosting freestyle skiing, ski jumping and biathlon.
