The International Energy Agency published a report “Nuclear Power and Secure Energy Transitions: From Today’s Challenges to Tomorrow’s Clean Energy Systems”, arguing that in order to achieve net-zero emissions by mid-century, the world’s nuclear power capacity needs to double , from 413 GW today. To 812 GW, annual nuclear power capacity in the 2030s would need to increase by 27 GW. This provides the opportunity to limit global temperature rise to 1.5 degrees Celsius above pre-industrial levels. In addition, nuclear power plants, which currently account for 63% of the world’s installed capacity or 260 GW, are more than 30 years old and are approaching the end of their lives. Nuclear power capacity in developed countries could shrink by a third by 2030 due to end of life. Developed economies account for 70% of the world’s installed nuclear power capacity, but nuclear power plants are aging and not many new nuclear power plants are being built.
