I Gordon Edwards, 9 June 21 the contribution of nuclear power to world electricity usage has declined from 17% (25 years ago) to 10% (today), and is expected to continue to decline for the next couple of decades at least. But electricity is only one slice of the energy pie. Nuclear power currently contributes about 2% to global energy use including all modes. So let’s see — some 440 nuclear reactors produce 2% of global energy usage. If none of those stop working, and we add 440 more reactors of equivalent size in the next two decades – that’s 22 large reactors per year, every year, starting now, a clearly impossible scenario – then we could theoretically supply 4% of the world’s energy needs by 2040, assuming energy demand doesn’t grow at all in the meantime
