> Eh, once you have built your grid in solar and wind, you don't really depend on the countries that sold solar panels and wind turbines for you.
You don't account for repair, replacement and upgrade? You don't want to expand your power grid? This is a very naive take to be honest.
No country should be stagnant with what they already have, that's a recipe for a disaster.
I can argue the same, once you have built your grid in nuclear and stockpile enough uranium for decades, you're pretty much set right? Those last for a long time as well :).
