Nuclear energy

Global nuclear power generation increased by 1.3% in 2016, or 9.3 million tonnes of oil equivalent (mtoe), marginally increasing its share of global energy from 4.4% to 4.5%

China accounted for all of the net growth, expanding by 24.5% (9.6 mtoe).This was the fastest growth in absolute terms in China’s history and similar to the growth seen in France’s rapid expansion in the mid-1980s. Generation in Japan and Belgium also grew strongly, while France saw a sharp decline (-8.1%, -7.7 mtoe).

Nuclear energy consumption by region (million tonnes oil equivalent)

Nuclear energy consumption by region (million tonnes oil equivalent)


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 the PDF. In addition the data are available in the Excel workbook in terawatt–hours (Twh).
