A report by 19 energy specialists from ETH Zurich and the Paul Scherrer Institute concludes that Switzerland can achieve a secure energy transition through hydropower, solar energy, wind power, and electricity storage without building new nuclear reactors.The study highlights that new nuclear plants face significant economic challenges, including high construction costs, delays, and financial risks.

Government support and state guarantees would be necessary for viability, but even then, costs remain higher than recent projects in France and Finland.The report aligns with previous analyses suggesting that while nuclear power is technically possible, its economic feasibility is questionable.Alternatives like expanding solar generation and investing in energy storage are deemed more practical.

The Swiss government's recent decision to lift the ban on nuclear plants faces potential opposition in a referendum, with voters likely to decide the final outcome.

Generation IV reactors, touted as safer and more efficient, are deemed unlikely to contribute meaningfully to Switzerland's energy needs before 2050 due to unresolved technical and economic challenges.
