风力发电被广泛认为是一种清洁、低碳、可替代燃煤发电的能源。然而，风力发电的定量研究在表明与燃煤发电相比对环境影响的差异方面有限。因此，生命周期评价（LCA）是用来比较环境排放的风力发电和燃煤发电。基于生命周期评价结果，描述了风电的物质流和能量流，并估算了风电的替代效应。对于1千瓦时（kWh），风力发电仅消耗与煤电相关的二氧化碳（CO2）排放和环境成本总量的4%。此外，风力发电的能源和排放强度集中在制造阶段，而煤电的能源和排放强度集中在运营和维护阶段。此外，风电建设阶段由于使用外购电力，环境成本略高于生产制造阶段，占总环境成本的47%。基于相应的生命周期评价，中国“十二五”期间风电的CO2减排潜力预计不到5亿吨。2020年预计实现减排3亿吨以上。最后，提出了促进我国风电产业发展的政策建议。
Wind power is widely regarded as a clean, low-carbon, and alternative energy source for coal-fired power. However, quantitative studies of wind power are limited in indicating the differences in environmental impacts as compared with coal-fired power. Therefore, a life cycle assessment (LCA) is utilized to compare the environmental emissions from wind and coal power. Based on LCA results, material and energy flow of wind power are depicted, and its substitution effects are estimated. For 1 kilowatt-hour (kWh), wind power only consumes 4% of the total amount of carbon dioxide (CO2) emissions and environmental costs related to coal power. Furthermore, energy and emissions intensities of wind power are concentrated in the manufacturing stage, while those of coal power focus on the operation and maintenance stage. In addition, the environmental costs of the construction stage of wind power are slightly higher than that of the production and manufacturing stage due to the using of purchased electricity, accounting for 47% of the total environmental costs. Based on a consequential LCA, the mitigation potential of CO2 emissions of wind power is estimated to be less than 500 million tons during the period of China's 12th Five-Year Plan (5 years). More than 300 million tons reduction is expected to be realized in 2020. Finally, some policy implications for Chinese policymakers are proposed to promote the development of the wind power industry.
