Diversifying energy portfolios to reduce water-related impacts on the energy sector is another effective adaptation strategy with high mitigation co-benefits. A modelling study from Europe shows that for a 3ºC scenario, an energy mix with an 80% share of renewable energy can potentially reduce the overall negative impacts on the energy sector by a factor of 1.5 times or more . In addition, hydropower can also play a role in compensating for the intermittency of other renewable energies . For example, integrating hydro, solar and wind power in energy generation strategies in the Grand Ethiopian Renaissance Dam can potentially deliver multiple benefits, including decarbonisation, compliance with environmental flow norms and reduce potential conflicts among Nile riparian countries . Furthermore, reducing the share of thermoelectric power with solar and wind energy  can be synergistic from both climate and water perspectives, as solar and wind energy have lower water footprints .
