The scale of that stuff is impressive. But it's the cheapest way they've found to do it. Rebooting the planet without fossil fuels would be very expensive, but absolutely doable. Use your imagination. Fossil fuel executives like to say the wind sometimes doesn't blow, which in most areas is true. But there are sites where the wind is very reliable which they conveniently ignore. Site your fab plant there, or put it next to a hydroelectric dam, or use tidal power. We certainly know how to store energy to counter intermittent sources, massive amounts of it, with iron age technology, but it's expensive. Pump water uphill and store it, pressurize a salt mine, store molten salts, etc etc. There's a lot of difference between saying "but that would require..." and just being a naysayer.
