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

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.
France will happily sell power to Germany and Spain for maybe 50 cents
per KWH, or whatever that is in euros.
0.44 euro per kW.h. France does generate a lot of it's power with nuclear reactors, when they work. That wasn't driven by economics, but by Charles de Gaulle's ambition to have a nuclear armed force de frappe.
They aren't all that flexible as a generating service, so France mostly sell power to its neighbours when it's consumers are using less and the neighbouring consumers are using more.
