Nuclear energy is not the solution

Nuclear energy is not the solution.

Nuclear power is a low-carbon source of electricity, and keeping an existing reactor running can be economical in some cases. That does not make every new reactor a good climate investment. New projects must also be judged by when they deliver, who carries their financial risk, how resilient their supply chains are, and how waste and security risks are managed. Here are seven evidence-based reasons not to treat new nuclear as the default solution.

Scope

This page focuses on barriers to expanding nuclear power—especially new construction in Europe and North America. It does not argue that nuclear is high-carbon or that every existing reactor should close immediately. Continued operation and lifetime extensions require a separate case-by-case assessment.

Seven reasons to question new nuclear

Each card separates the evidence, our policy conclusion and the strongest context that limits it.

    Our position and method

    This site argues against treating new nuclear power plants as a priority climate strategy, especially in Europe. We do not dispute nuclear power’s low life-cycle emissions, and we recognise that continuing to operate an existing plant can make sense in some circumstances. Each card separates checkable evidence from our policy conclusion. We prefer direct sources, name the relevant place and period, and include material counterevidence. Corrections and better sources are welcome.
