"If you still needed proof that nuclear energy has returned to the conversation after decades of disfavor, it came with an unexpected celebrity boost last month. Tesla CEO Elon Musk and the Canadian singer Grimes separately used their star power to advocate against the closure of nuclear power plants, echoing growing pressure for California to reconsider plans to shut its last such plant. Over the weekend, Europe also saw a fresh boost for nuclear energy with the leaked draft of a European Commission plan to include zero-carbon nuclear energy on its list of what counts as a “green” investment.

Notwithstanding Germany’s long-planned closure of three of its remaining six nuclear plants on New Year’s Eve, even as Europe struggles with energy shortages, support from celebrities and the EU was just the latest in a string of good news for nuclear energy in 2021. In the United States, private investment in nuclear projects and companies reached eye-popping levels. U.S. Energy Secretary Jennifer Granholm became increasingly vocal in support of nuclear power as a zero-carbon energy source. In Europe, several countries—including France—recently announced new plans to build nuclear reactors in order to meet looming deadlines to decarbonize their electricity systems.

A decade after the Fukushima nuclear accident set back nuclear power’s prospects worldwide, the outlook may finally be brightening for three reasons: the urgency of meeting increasingly ambitious climate goals, significant advances in nuclear technology, and national security concerns about China’s and Russia’s growing leadership in nuclear power."
