摘要:
新疆是我国电力生产的主要地区,同时存在严重的水资源短缺问题。作为综合评价指标,水足迹可以用来量化分析电力生产中的水资源消耗及其水环境影响。文中基于投入产出和生命周期的混合生命周期模型对新疆地区2012年和2017年电力生产水足迹进行了量化研究,并对不同发电技术的水足迹贡献部门进行了分析。结果发现:因电力生产结构的变化和燃煤发电技术革新,新疆电力生产的单位水足迹由2012年的4.26×10-3 m3/(kW∙h)下降到2017年的3.08×10-3 m3/(kW∙h)。对不同发电技术的水足迹贡献部门分析发现,煤电和水电的间接水足迹分别主要来自采矿业和重工业,占比分别为60.3%和52.8%。风电和光伏发电的间接水足迹分别主要来自重工业和轻工业,占比分别为38.1%和56.0%。最后针对碳中和目标下新疆电力结构转型带来的水足迹变化进行分析,2017—2050年高比例的可再生能源发电将使新疆电力生产单位水足迹下降75%。
