Fissionary

Singapore imports nearly all of its natural gas. It has no wind, and its rooftops can generate enough solar power to meet less than 10% of national demand. For a country that has committed to net zero by 2050, that math falls dangerously short. Nuclear was never the obvious answer. But the emergence of energy security concerns alongside the advent of small modular reactors has moved it from fringe...

After Fukushima in 2011, Japan went from getting roughly a third of its electricity from nuclear power to running zero reactors for two full years- and spending $270 billion more on fossil fuel imports in the process. Today, Japan's government has reversed course, officially committing to maximize nuclear energy in its national strategic energy plan. Jane Nakano, senior fellow at the Center for St...
