You might want to look at figure 26.10 of Scenario F. We still hit mineral constraints. The author says outright the report is not an attempt at simulating a realistic transition because it's asking first order questions: along the lines of "do we even have enough stuff to try this?". There's no attempt to ask if this is economical or logistically possible because it is not. The author is convinced that we're all about to be much poorer because the IV drip of cheap energy that the world has enjoyed for at least 50 years is about to be ripped out. Personally, I think what's most likely to happen is that we will fail to get the world's nations to stop using fossil fuels and we will suffer the environmental consequences of that. Plus all the consequences of the resource wars that will follow. It's a shame. I think our best chance to avoid this is to rush research on mass manufacturable gen 4 nuclear reactors. We need a factory that spits these things out so we can ship them to developing nations because otherwise, they build coal plants. I have high hopes for Thorcon. They plan to use shipyards to build annually up to 200 GW of modular shippable reactors.
