So what if it's a cold night with no wind? I'm not saying renewables aren't cheap, I'm saying that you can't fully construct a grid on them and that this has not been communicated.

Our energy is expensive and volatile because of this (and subsidies to implement it). You don't seem to be capable of following my argument. It's not a free lunch. Renewables are also slightly problematic for grid stability although I expect we will have enough fast storage / (possibly synthetic) inertia eventually.

You can add storage, which twenty five years ago looked completely impractical but it turns out actually no.
