At the factories that produce silicon and composites for the windblades.

So far, no large country has managed to move to 100% carbon-free renewable generation. And I'm not seeing this changing.

If we're talking about Europe, they are facing the problem of Dunkelflaute - long periods of no wind, no sun, and low temperatures in the middle of the winter. A worst-case once-in-century scenario would require around a _month_ of storage.

So far no technology is even close to that.

Dunkelflaute can be dealt with by burning hydrogen, not fossil fuels. You need backup turbines, but a simple cycle combustion turbine power plant is about 20x as cheap to build as a nuclear power plant, per unit of power output. So backing up the entire grid with these "Dunkelflaute turbines" is not expensive compared to the nuclear solution.

Europe has many petawatt hours of potential hydrogen storage capacity in its salt formations.

And if we compared these factories and their environmental impacts we would see a net increase from the production of solar and wind products? That's the point, and you ducked it hard.

Who said that we had to hit 100%? There is a place for burning stuff for fuels in our society for long to come, the point is not having it the default way we power larger systems.

Okay, that's a great argument to not continue investing in storage solutions, but let's be real, a new nuclear steam turbine isn't coming online _tomorrow_ either.

Let's do both, and not pretend like the more risky one is less dangerous than it is, when things go wrong.
