Tough wind generation is growing fast, much remains wrong with the industry
Row after giant row of wind turbines marches towards the snowy peaks of the Tian Shan range, harvesting energy from the air. On a blustery July day in Xinjiang in China’s far west, it is hard to stand upright beside the structures, each 90m (nearly 300 feet) high. China is better known as a land of coal and smog, but it is now increasing the generation of electricity from renewable sources faster than any other country, with more than 100 gigawatts a year of installed generating capacity from wind, a third of the world’s total (see chart). In future, wind power will be a vital source of renewable energy. If it can integrate large-scale wind generation into its electricity network, China will be an example for other countries.
