Mostly agree, but: > Not to mention that the exponential growth of solar panels is basically stabilized in climate right now. Sadly, growth of PV can only deal with part of the problem. We're making PV fast enough now that, given panel lifetimes, in 30 years 100% of current electricity demand will be met with specifically PV, and we're also making wind turbines and nuclear reactors and stuff. The "and also" means we'll probably also be fine electrifying land transport. Air transport (also fast-and-reliable sea transport) is somewhat harder to make renewable, but theoretically possible. Metal extraction from ore can be done electrolytically. Concrete's not limited by electricity, it's an independent thing to be solved. So is meat farming. Progress exists on these, yes, but my point is they're not solved just by us being on the home stretch for electricity. |
