Share of primary energy consumption that comes from nuclear power
What you should know about this indicator
- Figures are based on gross generation and do not account for cross-border electricity supply.
- Primary energy is measured using the "substitution method" (also called "input-equivalent" primary energy). This method is used for non-fossil sources of electricity (namely renewables and nuclear), and measures the amount of fossil fuels that would be required by thermal power stations to generate the same amount of non-fossil electricity. For example, if a country's nuclear power generated 100 TWh of electricity, and assuming that the efficiency of a standard thermal power plant is 38%, the input-equivalent primary energy for this country would be 100 TWh / 0.38 = 263 TWh = 0.95 EJ. This input-equivalent primary energy takes account of the inefficiencies in energy production from fossil fuels and provides a better approximation of each source's share of energy consumption. You can find more details in the Statistical Review of World Energy's methodology document.

How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
