Review by energy type: Nuclear energy

Nuclear fuel rods
World nuclear power generation declined by 6.9%, the largest decline on record for a second consecutive year

Japanese nuclear output fell by 89% accounting for 82% of the global decline. Nuclear’s share of global primary energy was the lowest since 1984.

Nuclear energy consumption by region

Million tonnes oil equivalent

World nuclear power generation declined by 6.9%, the largest decline on record for a second consecutive year. Japanese nuclear output fell by 89%. Nuclear’s share of global primary energy was the lowest since 1984.

Methodology

Data are based on gross generation and not accounting for cross border electricity supply.

The primary energy value of nuclear power 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).

Data for the units are in million tonnes oil equivalent (mtoe). In addition the data are available in the Excel workbook in terawatt–hours (Twh).
