WORLD NUCLEAR ENERGY

A record year, in context

Observed generation and future ambitions should not share one label.

What the evidence says

The IEA reports that nuclear generation grew 1.2% in 2025, reaching a record. Its earlier review places nuclear’s share of global electricity at 9% in 2024. Those figures describe different measures and years. They are not a forecast for a proposed project.

What a headline leaves open

A global total can include changes in operating performance, restarted assets and newly connected units. It says little by itself about a particular country’s institutions, project readiness or local demand.

When comparing an outlook with an observed result, retain the forecast’s publication date, scenario assumptions and time horizon. Do not restate a target as an achieved capacity.

A practical next step

Write down the question you need the evidence to answer. A primary source may support the existence of a programme without supporting a completion date or a commercial proposition. Keep those claims separate.
