Data Shows Slight Increase In 2020 Nuclear Generation
Nuclear power supplied 2,600 TWh of emissions-free electricity in 2020, accounting for about 10% of total global electricity generation and nearly a third of the world’s low-carbon electricity production, International Atomic Energy agency director-general Rafael Mariano Grossi said in an introductory statement to the board of governors.

This was a slight increase from 2,586 TWh in 2019. Earlier IAEA data shows the figure was 1,890 TWh in 1990.

Some 5.5 GW of new nuclear capacity was connected to the grid. As of today, there are 443 operational nuclear power reactors in 32 countries, providing about 393 GW of installed capacity. Another 50 reactors are under construction.

Mr Grossi said the agency is preparing to make its presence felt at COP26, scheduled for November in Glasgow. “I have initiated an agency-wide effort to bring together expertise from across our departments to support the message that I will personally deliver at COP26: that nuclear energy has a seat at the table when the world’s future energy and climate policies are being discussed,” he said.
