摘要：The German energy transition is not only a challenge for the technical system transformation but will also imply changes in the water system and reallocation of resource usage. This paper analyses which interactions provide valuable information for the energy system and how future water use projection could be conducted with the help of energy system modelling. It was assumed that different national climate policy scenarios for the energy system influence the water projections. The interactions considered for the German case study are: water demand for cooling technologies, irrigation practices of energy crops, as well as literature based assessments of total water demand and renewable water availability. Based on the energy scenario analysis, water use for the energy system will shift over time from cooling water use to irrigation water use for energy crops and the amount of irrigation water use is dependent on the demand of biomass which increases for stricter climate targets. There is a small risk of future water stress that can be eliminated through the use of recycled water for irrigation.
