No the scale of our electrical needs is easily met with nuclear. We just can't let capitalism run them.

Also op was talking about recently built reactors and new ones planned, China has built the most recently and has planned the most in the future. Why does everyone want to ignore the literal billions of dollars oil and gas has spent to spoil people's opinions on nuclear energy to the point that you just can't fathom building hundreds of plants around the globe.

Edit: what mechanisms exist in society that will allow us, the working class to change things to the point that we don't require as much energy in the future? Capitalism only knows consumption, and they're in charge. They own the oil and gas and they own the politicians that legislate. The future is the poor getting priced out of energy and dying, it's not a utopia of reduced emissions ushered in by shell, ExxonMobil and Halliburton continuing record profits.
