> The difference is, most of these costs _are_ factored in to renewable costs because there are few subsidies (at least at grid level
It will depend on location, but across the EU there are massive subsidies. Furthermore, recycling costs aren't included and are just starting to come to light with the decomissioning of the first generation of solar and wind generation platforms. Their limited useful life,bserious recycling costs and related pollution, and all of those on the energy storage required to actually make them useful for bade load are rarely a part of the discourse.
> I just don't understand why we're still talking about this when nuclear storage costs, even when included, are laughably optimistic
How so? Most of the problems around long term storage are political. The temporary swimming pools are still good enough for decades or even centuries to come, while projects on underground permanent storage are advancing ( most notably Finland iirc).
