The Paris-based International Energy Agency released its annual report on global electricity systems and markets on February 6, showing the output of nuclear energy at record levels in 2025. According to Electricity 2026, nuclear energy together with renewable energy sources (mainly solar) will generate about half of all global electricity by 2030, up from 42 percent today.

The International Energy Agency released its flagship report, World Energy Outlook 2021, on October 13, “at a time when policymakers are contending with the impacts of both climate change and volatile energy markets” and ahead of the COP26 Climate Change Conference in Glasgow, which begins October 31. With a net-zero emissions by 2050 (NZE) scenario that calls for nuclear power capacity to almost double by 2050, the report acknowledges that rapid development of advanced nuclear technologies could expand opportunities for nuclear energy to provide low-carbon electricity, heat, and hydrogen.
