I think you missed the sarcasm bit but ok.
You can boil this down to a very basic argument. If the renewable energy sources were as cost effective and reliable as the more traditional sources, every country in the world would be clambering over eachother to implement it. This includes left and right, it's basic economics at the core.
Why aren't they? Why do they have to be convinced and persuaded to even pay lip service to it? It's either because they're deluded morons that want to destroy the Earth - OR - it's because the renewable sources aren't as economically viable as you're conveying.
I'm willing to bet it's the latter. I don't care if you believe in climate change or not - or more importantly as to what extent you believe humans are responsible for it, to be honest this isn't my area of interest nor something I've studied at length - but you do not destroy your economy to virtue signal when the rest of the world isn't doing the same. It's madness.
You invest in the people and fund research, scientific advancement, engineering... To get you technologically to the point where net zero is not only economically prudent, it's financially profitable. That is capitalism.
