Due to droughts, hydropower generation decreased in 2021 for the first time in two decades, despite relatively high capacity growth
In the Net Zero Emissions by 2050 Scenario, hydropower maintains an average annual generation growth rate of about 3% in 2022-2030 to provide approximately 5 700 TWh of electricity per year. In the last five years the growth rate was just one-third of what is required, signalling a need for significantly stronger efforts, especially to streamline permitting and ensure project sustainability.
Without major policy changes, global hydropower expansion is expected to slow down this decade
