And my point remains unrefuted by anyone here including

which is till greenies embrace nuclear power they are just peddling bullshit about the alleged man made global warming diaster
Bad Premise. Getting to high 60-80% de-Carb is very possible. (and then adding/leaving some carbon and sequestration)
If one has to make the "100%" strawman it's indeed easy to shoot down.
We're a long way from worrying about the non-fossil needed portion.
A good article on this:
"...Two papers circulated widely among energy nerds in 2017 cast a skeptical eye on the goal of 100% renewables.
The other was a
paper in the journal
Renewable and Sustainable Energy Reviews that boasted “a comprehensive review of the feasibility of 100% renewable-electricity systems.” It was by B.P. Heard, B.W. Brook, T.M.L. Wigley, and C.J.A. Bradshaw, who, it should be noted, are advocates for nuclear power.
We’ll take them one at a time.
Most current models find that deep decarbonization is cheaper with dispatchable power plants
Jenkins and Thernstrom rounded up 30 studies on deep decarbonization, all published since 2014, when the
most recent comprehensive report was released by the Intergovernmental Panel on Climate Change (IPCC). The studies focused on decarbonizing different areas of different sizes, from regional to global, and used different methods, so there is not an easy apples-to-apples comparison across them, but there were some common themes.
To cut to the chase: The models that optimize for the lowest-cost path to zero carbon electricity — and do not rule out nuclear and CCS a priori — generally find that it is cheaper to get there with than without them.
Today’s models, at least, appear to agree that “a diversified mix of low-CO2 generation resources” add up to a more cost-effective path to deep decarbonization than 100% renewables. This is particularly true above 60% or 80% decarbonization, when the costs of the renewables-only option rise sharply.
Again, it’s all about balancing out VRE. The easiest way to do that is with fast, flexible natural gas plants, but you can’t get past around 60% decarbonization with a large fleet of gas plants running. Getting to 80% or beyond means closing or idling lots of those plants. So you need other balancing options.
One is to...."
Reasons for skepticism, reasons for optimism, and some tentative conclusions.
