Abstract

The transition towards a 100% renewable energy system may be an opportunity to resolve the water-energy
nexus. However, deployment of some technologies might impose additional strain on water
ecosystems. An energy-system-wide analysis of water demand in Europe was performed for the period
2015e2050 using the LUT Energy System Transition model for two scenarios: Area (with electricity
interconnections) and Regions (without). For fossil-fuelled power plants, the water footprint in 20 European
regions may decrease considerably until 2050, by 28.3% in the ‘Area scenario’ and 24.2% in the
‘Regions scenario’. However, total water demand in the Area scenario increases in 5 regions on average by
14%, from 7% (Balkan-West countries) to 24% (Sweden). Further, Turkey, Norway and Sweden may have
the largest water demands in Europe due to the commissioning of new hydropower plants. Results
indicate discussions on the sustainability of energy transition scenarios should be expanded to include
water footprint.
