There are serious concerns in the US ...(who have a high proportion of NG generation , and plenty of gas),... that in some weather /storm conditions of the Alaskan cold front looping down, that the National gas demand could easily exceed supply capacity, causing power plants to run short resulting in widespread forced shutdowns...just when demand is critical.

In short, for more than 40 years political inaction has resulted in *no* safe storage for nuclear waste in the US, a problem that's now causing enormous health concerns. Cleanup of *one* notoriously shoddy facility consumes 10% of the DOE budget, $2.4 BILLION a year, despite the fact it hasn't produced anything in over 30 years. Running these power stations at an enormous loss is still cheaper than the realized liability of closing them down and the associated political fallout (pun very much included). When you have politicians making the calls based on their personal electoral cycle you'll definitely fail to see meaningful action. The same is true in England and elsewhere.
Yes same problems worldwide,..but its a Political problem, not a technical one.
The solution is known and ready, but it will probably take a horrific disaster at one of those sites befor someone "grows a pair", and finishes the job.
And you keep conveniently forgetting that Solar/wind is not just "intermittent" and "variable". ..its also very "unpredictable". and as such unreliable if there is no back up systems or storage.
So, even if you retain Nuclear, or coal, or gas for overnight "base load",...what do you do on those days when the sun doesnt shine on that 50% of solar power that industry had become weaned onto ?

Solar/Wind predictions are no better than weather forcasts......and we all know how reliable they are.
But even the best weather forcasts cannot prdict the unexpected cloud bank or change in wind speed /direction.. all of which make a huge difference to grid management.
Many of those states/countries with high % of Solar and wind have had major issues with power crashes.
Germany has had to be "rescued" more than once..most recently by Poland, as a result of a still air mass not moving as predicted, and our own SA state had its famous blackouts last year due to unexpected storms.
Obviously, these problems can be avoided with a suitable grid back up , but you cannot do that if the majority of your generation is also wind or solar......because it is unreliable.

Not every night, and sometimes not very much.!
Do you really think you could depend On wind for a large proportion of nighttime supply ?.
