Taiwan Must Not Turn Back: A Message of Solidarity for a Post-Nuclear Future

TCAN, Statements of support from international energy scholars for Taiwan’s nuclear phase-out, 2025-08-19 Dr. Sun-Jin Yun | Professor and Dean, Graduate School of Environmental Studies, Seoul National University

Taiwan has made history as the first country in Asia to phase out nuclear power. Even before its formal policy decision, Taiwan had already halted construction of two nearly completed reactors at the Lungmen Nuclear Power Plant. Then, following its bold commitment to denuclearization in 2016, Taiwan laid out a clear roadmap and proceeded to permanently shut down all six of its operating nuclear reactors by 2025. In total, eight reactors were removed from Taiwan’s energy future. This achievement stands as a global milestone—one that not only reflects the wisdom and determination of the Taiwanese people, but also shows what democratic leadership and civic engagement can accomplish in energy policy.

As a Korean educator and researcher who has supported Taiwan’s anti-nuclear movement—traveling across the island to share the experience of Seoul’s “One Less Nuclear Power Plant” initiative—I have seen firsthand the strength of Taiwan’s civil society. I was deeply inspired by how communities organized, informed, and mobilized to ensure that energy decisions would be made not by technocrats or corporations alone, but by the people. Taiwan’s experience became a source of hope and pride for many of us in Asia, proving that an energy transition rooted in justice and public engagement is indeed possible—even in societies with high electricity demand and heavy dependence on imported fossil fuels, where renewables are still being developed.

Taiwan’s nuclear phase-out was not just a policy—it was a people-powered choice for the future. Let’s not turn back. Let Taiwan lead again.

But today, that progress is under threat. Taiwan’s opposition parties have proposed a national referendum to restart the final two reactors that were recently shut down. On August 23, Taiwanese citizens will be asked to vote on whether to undo what they have so carefully and courageously accomplished. That is why I write this statement—not only to express concern, but to offer international solidarity.

While nuclear energy is often framed as a low-carbon tool for addressing climate change, the reality is more paradoxical: the worsening climate crisis itself is undermining the viability of nuclear power. As the crisis worsens, rising ocean temperatures reduce reactor cooling efficiency, while extreme weather events—such as typhoons and wildfires—and jellyfish blooms, fueled by ocean warming, increasingly threaten plant operations. And in a region prone to typhoons and earthquakes, the risk of catastrophe is never far away. Above all, nuclear energy produces radioactive waste for which no nation on Earth has found a safe, long-term solution.

Meanwhile, Taiwan has made remarkable strides in expanding solar and offshore wind. Your country is already charting a path toward a resilient, renewable energy future. To reverse course now would not only be scientifically and economically unwise—it would undermine the very civic spirit that brought you this far. The world is watching. Taiwan has led before, and you can lead again.

Please stay the course. A nuclear-free Taiwan is not only possible—it is already underway. Let us not go backward, but forward together.
