So, over 25 y, that is only 0.09% of world GDP/y to provide the panels. Even with a full cost est of $58 tril from the paper above, the savings from electrifying & providing electricity with WWS vs BAU results in energy- & social cost payback times of 6 y & <1 y, respectively
This video showing how inexpensive it now can be to cleanly power our society is nice. I'd like to see the same type of analysis done including wind production data along with the solar. bsky.app/profile/embe...
WOW!!! I paid about $1 per W about 6 years ago. That "first principles" thinking really has driven solar to unbelievably low costs: How much does highly processed sand with a little bit of metal cost? Has to be under 5¢ per kW I guess.
