You are my hero, been telling this at clouds for years after I took a power engineering course. Solar and wind are cheaper until you consider storage and grid reliability. Grid storage battery can be used for peaker/frequency regulation regardless of what you used to charge them full stop.

Counter example. South Australia hit 80% of it's electricity production from renewables in the last two quarters:

Power prices are now cheaper then before renewables were took over:

Grid reliability remains about the same as everywhere else:

They're five times cheaper when you dont take storage into account. Theyre cheaper after you consider storage too.

Indeed, if you use solar and wind to synthesize natural gas and burn that for electricity (a process that is ~40% efficient) it's still cheaper.

This means that even on the darkest most windless winter days when the grid has to eat into long term seasonal storage, solar and wind energy is currently still cheaper than an MWh of nuclear power is on the sunniest, windiest days.

I too, am pro-grid scale solar (and wind). However, solar and wind require both land, or at least suitable locations. It aint compact. The decision to do solar might be constrained by population centers - you can't build it too far away, but can't be too close; there may not be such an available space.

Nuclear is compact, and can really be built anywhere (may be consider earthquakes and don't build near tsunami zones). Therefore, a country that does not have suitable solar or win terrain would necessarily have to consider nuclear. A place like South Korea.

But of course, countries like australia (and to some extend the USA, and many other countries that's not in europe) would have the land, and it's just political and financial reasons that these power sources aren't more invested in.

So you're advocating for a base load of natural gas power plants, with wind and solar supplementing them, which was my original point- that they only work as a supplement, rather than a replacement, for nuclear and fossil fuels.

Maybe nuclear isn't a great alternative to natural gas. I'm down with that. I'm not going to ignore the fact that wind and solar are at best complimentary, and that we can talk about pricing them without also talking about pricing in the base load that they're supplementing.
