China's wind power generation capacity has neared 40 million kilowatts, and it is under way to meet the goal of doubling the figure by 2015, according to an industry report.

During the first ten months this year, wind turbines generated 58.3 billion kilowatt-hours, an increase of 57 percent year-on-year, accounting for 1.5 percent of the nation's total electricity output, the State Electricity Regulatory Commission said in a latest report.

By the end of the August, 486 wind power stations were in operation across the country, with 39.24 million kilowatts of installed power generation capacity, the world's biggest. The under-constructed capacity was 13.77 million kilowatts.

It is estimated that China has exploitable wind power resources equaling 2.38 billion kilowatts on land, and about 200 million kilowatts offshore.
