With respect to hydropower, mountains play a unique role in the production of renewable energy for large downstream populations, but it also comes with important trade-offs affecting mountain ecosystems and populations  . Climate change requires adaptation in the hydropower sector; for instance, some advocate for increased water storage in dams and the importance of mountains for pumped hydropower storage systems , while others emphasise adaptive water management . An example is the multi-purpose use of water strategies where water management storage is designed to accommodate different uses, including hydropower, agriculture and flood risk reduction  . Hydropower is also especially vulnerable to glacier and snow decline  and is subject to risks from extreme events , social and political opposition  and the resulting financial uncertainty for hydropower investors. There is still limited evidence on how climate change impacts wind, solar and biomass energy production and their use.
