In 2009, the installed capacity in China has already passed 25 GW [21]. It is anticipated that China will extend the target to a total installed capacity of 300 GW by 2030. With this new target, if the average capacity factor for wind turbines in China is assumed to be 30%, wind could provide 0.79 PWh of electricity annually, theoretically reducing 780 Mtons of CO2 emissions that would have been generated by coal-fired power plants.
