Love the book, and agree that energy cost will go down, but I think that’s because of new and better technologies like nuclear SMRs, not solar panels which take tons of resources to manufacture, and flywheel and battery technology just aren’t progressing. We need more energy density, not less. I think it’s become clear that solar has many limitations, and cannot scale in any meaningful way. He also was a “global warming/carbon bad”guy when he wrote the book in 2019/2020. I am hoping the 4 years that followed may have changed his views on the topic, especially if her actually dug into researching the topic as opposed to just regurgitating the establishment narrative.
