风电设备生产及风电场建设产生的环境影响备受关注. 本研究以中国东南沿海城市某100 MW陆上风电场为例,基于生命周期评价方法,对其风机产品生产制造、运输、风电配套设施建设和运营维护等阶段的环境影响(以温室气体为归一化度量指标)进行了量化分析.研究结果表明,该风电场生命周期温室气体排放总量约为90 000 t(以CO2 当量计,排放强度为17.8 g/(kW·h)).其中,生产制造阶段占比最大(67.8%),其次为建设施工阶段(19.2%).与其他能源发电方式对比表明,风电温室气体排放强度明显高于水电(以CO2 当量计,约3.5 g/(kW·h)),但与光伏发电(以CO2 当量计,约50 g/(kW·h))、生物质(以CO2 当量计,约200 g/(kW·h))和火力(以CO2 当量计,约800 g/(kW·h))等能源方式相比,减排效益显著.
Wind power development is one of the main approaches and effective means to meet with the energy need. However, the negative environmental impacts by the production of wind power equipment and the construction phase of wind farm are also very pressing. In this paper, a 100 MW onshore wind farm in a coastal city in the Southeast China is taken as an example to quantify the environmental impacts measured by greenhouse gases emission, GHGs emission over its life cycle including the wind turbine production, transportation, wind farm facilities construction, operation and maintenance. The results show that the total GHGs emission of a 100 MW wind farm is approximately 90 000 tCO2 eq, and the emission intensity is about 17.8 gCO2 eq/(kW·h)), of which the emission during the stage of manufacturing accounts for the largest proportion (67.8%), followed by that during the construction stage (19.2%). Though the GHGs emission intensity of wind power is significantly higher than that of hydropower (about 3.5 gCO2 eq/(kW·h)), its GHGs emission reduction benefits are more significant over those of other power generation projects, such as photovoltaic power generation (about 50 gCO2 eq/(kW·h)), biomass (about 200 gCO2 eq/(kW·h)) and thermal power (about 800 gCO2 eq/(kW·h)).
