I like the transition to renewables , but there is nothing inevitable about it. We don't produce solar panels or have the materials to produce them in Europe.

I like the transition to renewables , but there is nothing inevitable about it. We don't produce solar panels or have the materials to produce them in Europe. So we're just as dependent on imports as before.

Those imports have a much longer half life than barrels of oil.

  But at the moments they cover only a tiny percentage of our electricity needs, not even talking about storage or the heating needs which usually come from gas.

    You objected that switching to solar would still leave the EU dependent on imports. Even if that is true the dependence isn't remotely equivalent.

It's aluminum, glass, silicon, and some conductive metal. Surely you all have those materials. And even if you don't make them yourselves, they aren't make and then burn like fossil fuels, they are durable infrastructure, you don't have to replace them often - they have an expected lifespan of >30 years. Buy as many as China will sell you, and once you have more than enough installed, you're good for a long time, regardless of whether they cut you off. I think being reliant on the fossil fuel supply chain for so long, it's a bit tricky to mindset shift that once these things are installed, you're just good. And they're super fungible, you don't need any precision replacement parts, so you can make your own replacement parts if you want.

    The observed lifespan of DER assets is consistently longer than the manufacturer’s (or insurance company’s) rating

    Yes, and France currently has a huge problem with keeping their plants online in the summer when it's too warm. And building new plants is outrageously expensive, see Hinkley Point C. Oh, ans you still need to import fission material, so you're dependent again on other countries. Nuclear was good in the 70s, now it's beaten thoroughly by renewables.

      The Swedish government is very pro renewables, yet it is initiating large investments in nuclear because they believe it is the only way to ensure enough electricity for the larger and larger need for it in the near future. I’d say they have some good information to base that decision on, since you’re right it’s really expensive, but also it’s the only way to get large amounts of production when the sun ain’t shining (all winter here) and there’s no wind (also happens a lot in the colder months).

        Right, a mix of uncorrelated sources is much more resilient than 100% renewables. Of the cleantech industry people I listen to, none of them are advocating for 100% renewables, you need a mix for grid reliability. But renewables can take on much of the load. And overpaneling can help significantly, and makes a lot more sense now that solar is super cheap.

Your comment makes no sense. If the Middle Eat oil gets cut off, you're suffering within days. If China cuts off solar panels, you have many plenty of time to find an alternative source or ramp up your own production. If you chase down all inputs into everything you need to generate power you will find you're not truly independent from anyone. But solar panels and various other renewables hardware is much easier to stockpile than oil. > but there is nothing inevitable about it The Middle East is not going back to normal any time soon. The Israeli/US attack on Iran is a strategic catastrophe, implemented by two felons advised by ideologues and incompetents. The conditions are right to make oil more expensive for a long time, regardless of the outcome of the war. True peace is very unlikely to never be achieved. For instance: Iran now has a massive incentive to build nukes. Meanwhile solar panel, wind farm, and battery prices are dropping like a rock and they avoid all of the problems of oil. Only the most ideologically fixated wouldn't invest in and install renewables. Anything that makes huge amounts of money is indeed inevitable.
