Countries Turn Back to Nuclear Energy Amid Climate and Energy Security Pressures

Governments are expanding nuclear plans, backing new reactors and small modular reactor development as electricity demand rises and clean energy targets tighten
Nuclear energy is gaining renewed momentum as countries look for reliable low-emissions electricity that can support climate goals, strengthen energy security and meet rapidly growing power demand. Governments are moving ahead with new nuclear plants, extending the life of existing reactors and supporting small modular reactor development as part of longer-term energy transition plans.
The shift is being driven by several pressures at once. Electricity demand is rising quickly because of economic growth, electrification, air conditioning, transport, data centres and artificial intelligence. At the same time, many countries want firm power sources that can operate regardless of weather conditions and reduce dependence on imported fossil fuels. The International Energy Agency says nuclear generation is set to reach a new global record in 2025 and continue rising in 2026, supported by reactor restarts in Japan and new reactors entering service in countries including China, India and South Korea.
Investment is also increasing. The IEA says nuclear investment has risen by about 50% over the past five years, with spending on new plants and refurbishments expected to exceed USD 70 billion. That rebound reflects renewed government backing, rising concern over system reliability and growing interest in advanced nuclear designs that may offer more flexible deployment options in the future.
Small modular reactors have become one of the most watched parts of the sector. The IAEA says global interest in SMRs is increasing because they may offer lower upfront capital requirements, enhanced safety features, flexibility for smaller grids, and uses beyond electricity generation such as district heating, industrial applications and hydrogen production. OECD NEA material also points to growing interest in using SMRs at former coal sites and in markets seeking dependable low-carbon power that can complement renewables.
This does not mean the path is simple. Nuclear expansion still faces major challenges, including high upfront costs, long construction timelines, licensing complexity, financing risks and public acceptance. The IEA says a broader nuclear resurgence will depend on whether governments and industry can control costs, improve project delivery and build the supply chains and skilled workforce needed for a larger buildout.
Even with those obstacles, the direction is becoming clearer. Nuclear power is increasingly being treated not only as a climate tool, but also as a strategic part of future electricity systems in a world demanding more clean, stable and secure energy. That is why more countries are returning to nuclear power discussions, and why SMRs are attracting growing policy attention as part of the next phase of the global energy transition.
