You can’t just cut and paste progress forward. Battery technology is still two or three decades away from being able to fully replace fossil fuel use. Lithium batteries are not the answer there’s just not enough lithium and it can’t be refined fast enough. Even completely replacing fossil fuel electricity generation would take three decades and there’s no technological hurdles, it’s just scaling manufacturing and construction resources to build that many plants. The scale of these efforts is hard to grasp.
It’s not states estimates it’s estimates to create 4,000 Terrawatt hours of generation capacity (fossil fuel capacity in the US). To put that in context that’s 2,000 Hoover dams $1,600,000,000,000 or 60 years of spending the whole GDP. Looks like my 30 year forecast was overly optimistic.
Transportation has technicological hurdles, no amount of effort can solve this problem without breakthroughs in technology. It’ll be a long time before there is even a path to eliminating fossil fuels for transportation.
