Hydroelectricity

World hydroelectric power generation rose by 5 mtoe, just 0.9%, compared with the 10-year average of 2.9%

The US (7 mtoe) provided the largest increment. China’s growth was the slowest since 2011, while European output declined by 10.5% (-16 mtoe).

Methodology

Data are based on gross primary hydroelectric generation and not accounting for cross-border electricity supply. The primary energy value of hydroelectricity generation has been derived by calculating the equivalent amount of fossil fuel required to generate the same volume of electricity in a thermal power station, assuming a conversion efficiency of 38% (the average for OECD thermal power generation).

In the hydroelectricity consumption PDF table, the units are in million tonnes oil equivalent (mtoe). In addition the data are available in the Excel workbook in terawatt-hours (Twh).
