中国电力行业的二氧化碳排放量约占全国总排放量的40%。风电替代煤电是实现我国CO2减排目标的关键。运用生命周期评价（LCA）方法，确定了我国典型燃煤电厂和风电场的碳足迹分别为810.35 g/kWh和12.51 g/kWh。在此基础上，探讨了实现2020年和2030年CO2减排目标的风电替代煤电能力。最后得出我国风电发展速度需要超过《可再生能源发展“十二五”规划》提出的2020年减排45%的目标。分析了风电替代火电的可行性。有人认为，虽然中国拥有丰富的风力资源，实现这种替代的潜力很大，但全面实现替代需要对该国的电力部门进行一些彻底的改革。
China's power industry contributes around 40% CO2emissions to the national total. The substitution of wind power for coal-fired power is crucial to the realization of CO2emission reduction target in China. By deploying the Life Cycle Assessment (LCA) method, this paper identifies that the carbon footprints of a representative coal fired plant and a wind farm in China are 810.35 g/kWh and 12.51 g/kWh respectively. Built on these results, the substitution capacities of wind power for coal-fired power to realize the CO2emission reduction target in 2020 and 2030 are discussed. It is concluded that China's wind power needs to develop faster than the goal set in the 12thFive Year Renewable EnergyDevelopment Planfor achieving the target of 45% emission reduction in 2020. Moreover, the feasibility of the substitution of wind power for coal-fired power is analyzed. It is argued that whilst China has great potential to realize such substitution given its rich wind resources, the full realization of the substitution requires some radical reforms in the power sector in the country.
