After the nuclear meltdown at Fukushima, Japan pulled its reactors offline and increased coal imports and natural gas to fill the energy gap. The disaster also prompted other countries, including Germany, to phase out existing nuclear reactors or stop building new ones amid public concerns over safety. Ten years later, most of Japan’s reactors remain offline due to considerable public opposition to their re-opening. But elsewhere in Asia, nuclear power plants are still being built. The World’s environment correspondent Carolyn Beeler examines how Fukushima has changed the global trajectory of nuclear power.
