Meta-study on energy scenarios

  • The energy sector today accounts for about 10% to 15% of global freshwater withdrawal. Most water in the energy sector is used for generating electricity, especially for cooling processes in thermal power plants. At the same time the demand for electricity is expected to increase significantly due to population growth and economic development in emerging and developing economies. Growing demand is also driven by electrification strategies pursued by industrialized countries to decarbonize their economies. With the global demand for electricity expected to increase significantly in the coming decades also the water demand in the power sector is expected to rise. However, due to the on-going global energy transition, the future structure ofThe energy sector today accounts for about 10% to 15% of global freshwater withdrawal.

Growing demand is also driven by electrification strategies pursued by industrialized countries to decarbonize their economies. With the global demand for electricity expected to increase significantly in the coming decades also the water demand in the power sector is expected to rise. However, due to the on-going global energy transition, the future structure of the power supply - and hence future water demand for power generation - is subject to high levels of uncertainty because the volume of water required for electricity generation varies significantly depending on both the generation technology and cooling system. In light of these challenges the objective of this analysis is to provide more systematic and robust answers in terms of the impacts of different decarbonization strategies in the electricity sector on water demand at global and regional level. The focus is on operational water use for electricity generation.show moreshow less
