Hydropower and renewable energy capacity worldwide 2008-2021

In 2021, the global installed capacity of renewable power surpassed three terawatts, approximately 1.2 terawatts of which were derived from hydropower. Through the use of mechanical structures such as dams and watermills, energy through hydropower can be generated from falling or fast-moving water and is a reliable, flexible energy source.

Hydropower consumption worldwide

Hydropower has come into greater demand over the past two decades, with global consumption increasing significantly since the early 2000s. China consumes the most hydropower of any country by far, followed by Brazil and Canada, each at about a third the rate of China.

Where is hydropower made?

Many of the world’s largest hydroelectric dams are located in China, and to a lesser extent, Brazil, contributing to high hydropower generation in these countries. The Three Gorges Dam on the Yangtze River in China is considered the largest hydroelectric dam in the world based on generating capacity. It was completed in 2012 amidst controversy, which concerned the displacement of residents and environmental problems associated with the dam’s maintenance and construction.
