What happened in 2019? The big picture

摘要

At the end of 2019,447 commercial nuclear power reactor units were in operation worldwide, totalling 396.2 GW in net installed capacity, a decrease of 0.2 GW since the end of 2018. Nuclear power generated around 10% of the world's electricity in 2019, or almost one third of all low-carbon electricity, and was set to remain the second largest source of low-carbon electricity after hydro power, the International Atomic Energy Agency (IAEA) has said.
