SHANGHAI, April 10 (Xinhua) -- Installed capacity in China's wind power sector will grow 64 percent this year to 20 million kilowatts, organizers of the 3rd China (Shanghai) International Wind Energy Exhibition and Symposium 2009 forecast Friday.

    Installed capacity grew 105 percent last year.

    Chinese industry experts believe that by about 2020, wind power will likely surpass nuclear power as China's third-largest source of electricity, after thermal and hydro power.

    Wind power comprised 1.5 percent of China's total installed capacity in 2008, when the country became the world's fourth-largest wind power market.

    The three-day event, which attracted 237 overseas companies, is due to conclude Friday in Shanghai.
