To be honest Ludwig, I consider that to be a straw man.Ludwig wrote: I'm sceptical that wind and solar power can sustain the current world population at even a fifth of the West's current standard of living.
A Good standard of living is unevenly distributed and it's likely to continue that way.
An example is Oslo. I suspect they will continue to maintain close to their current standard of living even if the rest of us devolve to third world levels.
They have an all-electric transport system and their power source is hydro.
We have a very wasteful fossil fuel system which burns three quarters of the energy to move the same amount of people or product, with only a quarter actually doing the work.
Logic dictates that if we go all-electric then we don't need all the fossil fuel energy. With a combination of wind, solar, tidal, hydro, geothermal and nuclear and coal to bridge the gap, I'm pretty sure it could be done.
I say "could" though. I in no way mean "will" and in fact it looks to me like "won't".
Which doesn't necessarily mean that the entire world sinks, but it probably means the UK and other less forward thinking countries will.
