Watch out for arb with the new renewables market. They can't add to more than 100%.

You absolutely NEED to distinguish between primary energy consumption and electricity production here! Primary energy consumption (e.g. in the Our World in Data link you share) includes any source of energy, which means that cars that run on gasoline count as "oil consumption", coal-fired blast furnaces count as "coal consumption", and a wood stove counts as "traditional biomass" although in none of these cases is electricity ever produced or consumed. By most estimates, electric power generation (which is a strict subset of primary power generation) accounts for <30% of all primary energy consumption!

It's hard to find consistent global numbers on this but you can see this very clearly in this Sankey figure for American primary energy consumption (https://flowcharts.llnl.gov/commodities/energy), keeping in mind that as a highly developed nation electricity comprises a substantially greater fraction of American energy usage than in most of the rest of the world. In 2022, the US consumed just over 100 quads of energy, only 37.7 quads of which was electricity! This means that nuclear energy was just over 20% of the overall electricity mix, but was only ~8% of the overall energy mix.

@pyrylium The way this question is worded clearly relates to global ENERGY production, not global electricity production. By this metric nuclear is (in 2022) only about ~4% of global energy, as clearly calculable in the very figure you share: 6702 TWh nuclear / 178899 TWh total = 3.746%!

@pyrylium yes thus question us about energy production. I'll add a comment to the description so that people are aware that there's a big difference.
