If China can reach a total installed capacity of 300 GW in 2030 as predicted, annual savings of CO2 emissions could amount to 780 Mtons. In this case, however, wind electricity would supply just 8.5% of China’s total electricity demand in 2030, lower even than present-day condition in Europe where wind electricity accounts for 4.8% of the total energy consumption. There is ample room for more rapid development of wind energy in China accompanied by larger CO2-saving potential. Compared with other energy sources, wind power has the greatest potential to reduce CO2 emissions, especially through onshore, large rated power turbines that have low emission per functional unit.
