Electricity generation from hydropower generation fell to its lowest level globally since 2000, owing to low rainfall last year. It is expected to drop further this year as heat waves and droughts sweep across China, the United States, and Europe.
According to Global Electricity Review 2022 by Ember, an independent energy and environment think tank, clean energy accounted for 38 percent of global electricity in 2021, including 15 percent generated from hydropower.
