Nuclear energy - 2015 in review

Global nuclear output grew by 1.3%, with China (+28.9%) accounting for virtually all of the increase

China has passed South Korea to become the fourth-largest supplier of nuclear power. Elsewhere, increases in Russia (+8%) and South Korea (+5.3%) offset declines in Sweden (-12.6%) and Belgium (-22.6%). EU output (-2.2%) fell to the lowest level since 1992. Nuclear power accounted for 4.4% of global primary energy consumption.

Nuclear energy consumption by region (million tonnes oil equivalent)

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 the PDF. In addition the data are available in the Excel workbook in terawatt-hours (twh).
