Firstly, I think we need to look at the Green New Deal as a discussion point. The discussion has started and when the hysteria dies away some progress will be made.
All power generation has a price; as a society we have to decide and accept how we are going to pay.
The sources of electricity need to be diversified and a commitment made to eliminating the use of coal. European countries have made a start on this.
Nuclear power is not the easy panacea that the article gives. Construction is massive, location is defined by the need for cooling water (as are all thermal generators),the waste is long lasting (to put it mildly), in this day and age security is a concern. I believe its use in Europe is contracting, the French were always the greatest proponents.

I’m going to be honest. It’s an incredibly optimistic plan. Obviously it would never be feasible given the country as it is. We have many community’s that don’t have clean drinking water and safe infrastructure. I would hope something like this would be a few decades out. I also didn’t know the plan was to go away from nuclear power. I apparently need to read more about it. Europe relies on nuclear without issue.

I agree that it is not a good idea to panic and shut currently functioning nuclear plants, but I disagree with Mr Michael Shellenberger that concern about nuclear power is irrational. Humans are fallible and the earth is geologically unstable. Has Mr Shellenberger never heard of Chernobyl and Fukishima? Apart from those well-known disasters that made significant areas uninhabitable, it would seem that nuclear power is not economical without taxpayers assuming the excess risk. In the USA that risk assumption is known as Price–Anderson Nuclear Industries Indemnity Act of 1957. If nuclear plants in 2019 still cannot be privately insured, then why build any more? Private industry wants to take us back to the moon and then to Mars; but no one wants to insure a nuclear power plant against all risks.

I am skeptical that CO2 emissions are bad for humanity. The earth is greening, and the mild warming that occurs due to more CO2 in the atmosphere has been greatly exaggerated. Burning fossil fuels is a recycling program that turns coal, oil, and natural gas into trees and other photosynthetic plants. [nasa.gov]
