Global nuclear energy capacity could increase substantially by 2060 as countries explore ways to strengthen energy security, reduce carbon emissions and meet growing electricity demand. Long-term projections associated with the International Atomic Energy Agency (IAEA) have highlighted the potential for significant expansion in nuclear power over the coming decades.

The outlook reflects renewed interest in nuclear energy as governments seek dependable electricity supplies alongside the expansion of renewable sources such as solar and wind power.

Rising Demand for Reliable Electricity

Electricity consumption is expected to remain an important challenge for countries developing digital infrastructure, manufacturing industries and large-scale data centres. Nuclear power plants can generate electricity continuously, making them a potential component of energy systems that also rely on weather-dependent renewable sources.

Supporters of nuclear expansion argue that it can help diversify energy supplies and reduce dependence on fossil fuels. However, the extent of future growth will depend on national policies, investment decisions and the pace at which new projects can be completed.

Nuclear Power and Climate Goals

Nuclear power produces very low direct carbon emissions during electricity generation. For this reason, several countries consider it an option for reducing emissions while maintaining reliable electricity supplies.

Nevertheless, nuclear projects face substantial challenges, including high construction costs, lengthy development periods, radioactive waste management and strict safety requirements.

Countries considering new reactors must evaluate these factors alongside the benefits of low-carbon electricity production.

Technology and Investment Will Shape Expansion

Future growth could be supported by new reactor designs, improvements in construction methods and the development of small modular reactors. These technologies are attracting interest, although their commercial deployment and economic competitiveness vary.

International cooperation, skilled workforces, regulatory oversight and long-term financing will also influence whether projected capacity increases become achievable.

What a Larger Nuclear Sector Could Mean

A substantial increase in nuclear power capacity by 2060 would represent a major change in the global electricity mix. It could help some countries improve energy security and advance climate objectives, but the outcome would depend on implementation, public acceptance and the performance of alternative energy technologies.

Long-term projections should be treated as scenarios rather than guaranteed outcomes. Actual nuclear capacity in 2060 will depend on decisions made by governments, utilities, investors and regulators over the coming decades.
