Infographic: Nuclear Power, From 5 MW to 9% of the World’s Electricity

Seventy years separate the 5-megawatt Obninsk reactor from a fleet of more than 400 reactors supplying roughly a tenth of the world's electricity. Three accidents, at Three Mile Island, Chernobyl and Fukushima, set the industry back by decades each time; today's revival is driven by grid demand from data centres and by climate targets.
