I don't know where you looked then because batteries are not anywhere near low cost enough to be deployed at grid scale at the amounts required to run a grid of wind and solar. Even in a sunny climate with reliable solar output, if you assume that there is a 10% chance that in any year you will have a 10 day period of cloud cover and 50% lower solar output and your entire grid cost goes up by 5x! The math for storage is BRUTAL.


Only 50%? That’s a small enough reduction that the cheapest solution is double the PV.


you're ignoring how big grids can get. there has never been a day where the entire US was cloudy at the same time.


But then you need to massively upgrade the transmission capabilities. There's no free lunch here.


It's not a free lunch, but it's a lot cheaper than not doing anything about climate change.


I don't think anyone was arguing that, it's more that geographic distribution of solar panels and windmills isn't a silver bullet and there's a reason solar and wind need expensive storage.
