Nuclear accounted for 4.1 percent of the global electrical generation capacity in 2023. In a scenario in which the nuclear expansion is globally supported by relevant policies, the share of nuclear power capacity is estimated to increase to five percent of the total electrical generating capacity by 2040 and decrease in the following decade. In the low case scenario, the nuclear share of global electrical capacity would plummet to 2.5 percent by 2050. The nuclear energy share of global energy generation is accordingly projected to decrease to less than seven percent if nuclear power targets are not set for the next decades.
Nuclear share of electricity generation capacity worldwide in 2023 with a forecast to 2050, by scenario
According to the source, the low case scenario assumes that current market, technology, and resource trends will continue; few additional changes in laws, policies, and regulations concerning nuclear power will be made. No assumptions concerning targets for nuclear power are made.
The high case scenario takes into account existing policies as well as publicized intentions of individual countries regarding expansion of nuclear power use. While more ambitious, the high case projections are still plausible and technically feasible.
