초록

Energy is closely interlinked with water. It is expected that water availability will decline due to various causes including population growth, economic growth, enhanced living standards, and climate change. Therefore, efforts are being made to capture energy-water nexus and reflect the interlinkage on domestic energy and water-related policies, as integrated management for water and energy resources are necessary to respond to climate change and to steer the economy towards sustainable development. This study estimated water use and direct·indirect water use intensities by energy sector using input-output analysis. Direct water use intensities were highest in the anthracite coal and briquette sectors followed by fossil-fired plants and nuclear power plants. Although new and renewable energy does not directly use water, total water use intensity was high in these sectors also, since a significant amount of water is used to manufacture NRE devices. According to an increase in final demand, more water is required across the domestic economy in nuclear power plants compared to fossil-fired power plants. This means that additional nuclear power plants or the increased operation of existing nuclear power plants will require more water across the economy compared to fossil-fired power plants. These findings imply that, although nulcear power seems an attractive alternative for climate change mitigation, in relation to water in particular, it is not likely to be an appropriate option for climate change adaptation.
