What's net zero is the line voltage. The issue is partly spinning
mass, but more important is gross gigawatts available on bad
afternoons.

Another time bomb is that (cheap) solar panels and inverters and
batteries don't last as long as is assumed in payback calculations. In
10 or 15 years there will be an enormous disposal problem. And lots of

Yep.  And given the likely end of the mandates and subsidies,
replacement may prove expensive, making the business case less
attractive.

I remember not too long ago when the climate-change deniers were claiming renewables could never be a significant part of a country's energy profile but I guess when they find out Spain was running 73% one afternoon they have to change their argument, lol.

Better question is will the fission nuclear industry ever give up trying to push their obsolete pointless technology that has been nothing but broken promises for 75 years. It's over give up, already.

 Fission works fine, although admittedly it's getting bogged down by
regulations and its reputation has suffered from some extensively
publicized accidents. Nuclear hasn't caused even close to as many
fatalities as has coal. France runs on nuclear power and it's doing
fine.
 It's fusion that has failed to live up to its promises.
 Renewables can be made to work, but need to learn to play well in
the existing infrastructure and need some kind of backup which
makes it more expensive.

Some global-warming denialists seem to have come around to the idea of "Well it's happening, but it doesn't matter" but how fresh water resources will go _up_ with less and less snowfall and less and less snowpack every year is anyone's guess.
It works "fine" if one buys the BS that other than the lil waste problem it's earth-friendly low-impact technology. It isn't it's hugely water-hungry, and uranium mining only gets dirtier the more of it you extract.
