Previous studies of water use for coal-fired power generation may have overlooked inter-sectoral impacts in the supply chain.Indeed,to devise effective water conservation strategies during the ongoing energy transition,it is of utmost importance to analyze the sectoral water use structures and flows in the supply chain and identify the sources of water scarcity.Therefore,based on the power sector-split environmentally extended input-output(EEIO)model and the life cycle assessment(LCA)idea,we comprehensively analyze the nexus between coal-fired power generation and water use from a sectoral perspective.Our findings reveal a complex and diverse water use structure in coal-fired power generation.The technology of production inherently determines the high intensity of water withdrawal,and the close intersectoral linkages,particularly with agriculture,construction,and some industrial sectors,in the production process result in an intricate web of indirect water withdrawal and blue water footprint(WF).Moreover,the grey WF,primarily sourced from coal mining and indirectly tied to tertiary industries,underscores critical areas for attention in water pollution management.Finally,water use in the coal-fired power sector is projected to remain at elevated levels in the short to medium term under various transition strategies.Following an in-depth exploration of the coal-fired power-water use nexus,the findings can offer new perspectives and specific entry points for sustainable energy development and water resource management.
