A very good graph from Statista showing the development of nuclear energy programs worldwide and it's share in global energy production.

"Despite the plateau in nuclear energy programs, the relative importance of the technology has still decreased as the capacity of other energy types outgrew nuclear. In 2021, the technology produced less than 10 percent of global electricity, down from a high of 17.4 percent in 1995 and 1996. Looking at all of the world's energy needs, not just electricity, nuclear contributed just 4.3 percent." (Statista)
