> Do you have an order of magnitude more land and water you're able to put wind generation on?
Actually yes. We currently use less than 0.5% of our agricultural land for PV (and some agricultural use is technically possible below PV). We could of course dedicate 5% or even 10% of land use to PV, if we really needed to (which we don't). We also could still expand PV to large swathes of build-up area (car parks and the like).
And Wind turbines actually don't need much space at all, the main issue is distance to settlements because of noise/shadow concerns.

I think there is an interesting discussion to be had. If we could i.e. half the cost of energy but have to live with drastically reducing energy consumption every few years for a couple of weeks in winter, would that be worth it?
We actually did so in the first winter after the Russian invasion of Ukraine, because energy prices rose dramatically and people and businesses reacted accordingly. That was painful (and had no upside whatsoever), but I think if it didn't come completely by surprise but would be a designed part of the system, it might be worth it.

That doesn't solve your problems in the slightest. You get less than half the return on investment for PV that most other countries in the world get, and does nothing for when your peak energy load is. Every dollar spent on PV requires another dollar on natural gas for the winter and locks you into fossil fuel dependency. Spend the money on something which gives you winter power!
> the main issue is distance to settlements because of noise/shadow concerns.
That's exactly what I mean. Where can you actually build it? And is that enough? And why spend a dime on solar until you've maximized wind?

See, exactly, that's the kind of national conversation you (and here in the USA) should be having. But we don't do that kind of thing any more. The politicians make money lying about the costs of things -- Gerhard Schröder being, I guess, a Russian stooge at best, a great example of downplaying the full costs.
