Global Hydropower Generation

Hydropower generation depends heavily on rainfall, which affects reservoir levels and river-flow conditions. In Brazil, for example, a wave of droughts has reduced output. Worldwide, hydro is by far the leading renewable energy source, supplying 15.6% of global power, behind coal (36.4%) and natural gas (23.3%), but well ahead of wind (5.3%). China is the world’s largest producer of hydropower, holding a substantial lead over Brazil, Canada and the United States.
