"with wind the single-biggest contributor.... Power production costs have declined “by almost half” .... And the clean energy sector has created 50,000 new jobs.... Ask me what was the impact on the electricity sector in Uruguay after this tragic war in Europe — zero."

The problem is usually not 4 good months but the time when you don't have renewables since the demand is still there, or even higher (during winter). And then you have problems (see Germany, which is currently the biggest polluter around because of their renewables policy). They are lucky that they have majority of energy coming from hydro, since that is quite reliable, but still, what happens if drought strikes? Not an impossible scenario in these times of global warming. How much fossil fuels are they burning yearly instead of running a nuclear power plant?
I'd be more than happy if renewables did solve all problems, but I don't see how can that work today.

I see what you're saying but the only tangible reply is: perfection is the enemy of good.

If we get to a point where half the world is doing this while falling back to fossil in emergencies, while the other half has a 100% success rate with nuclear, then the case is clear.

But that's not where we are and this, on its own terms, is a step away from fossil fuels as a primary solution, which is progress.
