Résumé
Climate change and the needed reductions in the use of fossil fuels call for the development of renewable energy sources. Hydropower is today the dominant renewable technology in the energy system and in some regions extensive development of hydropower is expected in the coming years. The IPCC Special Report on Renewable Energy Sources represented a benchmark in the assessment of water consumption from electricity production. The numbers for hydropower ranged from very low to much larger than the other renewable technologies, partly explained by methodological problems. This PhD has contributed by A critical assessment of the existing methodological framework for calculating water consumption from hydropower production Proposing methodological improvements Evaluating the trade-offs between the elevated water losses from reservoirs and the increased availability of water due to storage An improved understanding of the role of reservoirs in water resources management
In arid and semi-arid regions with potentially high evaporation rates, the contribution of water losses from the operational phase seem to dominate over the other life... , and the water consumption might also be more problematic in these regions. The thesis has also investigated the importance of water consumption and the role of reservoirs in water resources management in two semi-arid and highly regulated river basins..
