Nuclear energy has become a major topic in discussions about moving away from fossil fuels and toward cleaner energy sources. Although the number of nuclear reactors under construction has increased, this growth has not yet made a significant difference in reducing carbon emissions from the world's electricity supply. The World Nuclear Association (WNA) recently updated its list of reactors being built around the world, showing about 80 projects—22 more than in 2024. This growth is mostly happening in Asia, particularly in China. Even with the rise in new projects, the total nuclear power available has not changed much over the last 20 years. During this time, 111 reactors were shut down, while only 101 new ones were started. In 2024, 440 reactors in 31 countries generated 2,667 terawatt-hours of electricity, just slightly above the record from 2006. Nuclear energy provided 9% of the world's electricity, but new reactors are not being built fast enough to keep this share stable, and it might even drop in the future. Nuclear energy is getting more attention because reactors can produce a lot of power consistently and operate at high efficiency. Some countries are starting their first nuclear programs, including Kazakhstan, Poland, Uzbekistan, and Vietnam, all of which have projects in development. Bangladesh, Egypt, and Turkey are currently building their first nuclear power plants. Despite the renewed interest, building nuclear power plants remains a difficult challenge for many countries. These projects are large and require a lot of money and changes to the electrical grid. Countries starting nuclear programs often lack the technical knowledge needed and must work with other countries that have the expertise to build reactors, such as the United Kingdom, the United States, France, China, and Russia. These partnerships can be complicated, especially when political tensions are high between countries.
