28. Wind and solar have a overwhelming advantage

They don't have to pay for fuel and because of economies of scale they will continue to get better and cheaper.

Wind power is driven by a simple function - double the diameter of the blades and you cube the output, which is they continue to get bigger. Wind is always blowing somewhere so the biggest hurdle is a grid of HVDC transmission lines to bring the power to where it's needed.

"solar panels need to be replaced every few decades" - I have a hard time believing that bit of disinformation. Typical solar panel warranty guarantees 80% of rated output after 25 years. It's a straight line degradation of less than .5%/yr. You should still see 50% of rated output after 50 years. What will happen when more efficient panels get developed is the re-tasking of older panels.
Say the new owner of a house with old panels on wants to update. They won't throw the old ones out - there will be a market to sell or donate to non-profits (homeless shelters - churches - schools). At any rate they present less chance for hazardous waste than the millions of electronic devices that are being thrown out daily.

Batteries have gotten a lot better in just the last 10 years and we are just getting started using them to deal with fluctuations in the grid (which they do quicker and much cheaper than either coal or nat gas).

Insurance absolutely will not get cheaper - it never has. Principle reason is that the damage an accident at a nuclear plant creates gets more expensive to clean up - not cheaper.

BTW, I think we should find a way to keep existing nuclear plants generating power, but each plant uses about 20 tons of fuel rods a year so they are absolutely not risk or cost free.
