Nuclear power provides 10% of global electricity, but to stem climate change the world is going to need far greater amounts of clean and reliable energy, the International Atomic Energy Agency says in a short film it published today. To tackle climate change, 80% of all electricity will need to be low carbon by 2050. //

Several countries are developing small modular reactors (SMRs) and one has already been built in Russia, it adds, referring to the floating nuclear power plant Akademik Lomonosov.

Rebecca Casper, mayor of Idaho Falls in the USA, said SMRs can "integrate beautifully and seamlessly with wind, with solar, with some of those other sources that are maybe intermittent but that are also carbon-free". Nuclear power is "the key," she adds, “that makes all of that other desirable alternative energy possible because alone it just can't sustain a growing population."
