I MUST confess to being a supporter of nuclear power. Yes, there have been some highly dramatic safety incidents--Chernobyl, Fukushima, Three Mile Island--but there is quite a lot of nuclear power around. It produces about 11 percent of all the world’s electricity. In the UK and USnuclear power provides about 20 percent of national electricity. The top user is France where nuclear contributes 76 percent of all power.
