I guess that worked out just great, trucking using only sustainably fueled trucks all those solar cells and batteries around for a "green concert" with only sustainably produced electrical engineering.
(If it's any comfort, the author of the paper linked above under "batteries," documenting the slavery connected with cobalt is the antinuke Benjamin Sovacool, who also thinks that nuclear energy is "too dangerous" and "too expensive" but extreme global heating is not "too dangerous" or "too expensive." Nonetheless, despite his "renewable energy will save us" rhetoric, he seems to step back and feel some moral twangs of guilt about the results of this rhetoric, only one of which is human slavery. I hold a low opinion of him, but at least he has enough moral depth to recognize some, certainly not all, the effects of his advocacy.)
As for results, here's the result that matters to me, appreciating the outcome of 50 years of "no nukes" concerts, how I think it all "worked out:"
Week beginning on July 28, 2024: 424.93 ppm
Weekly value from 1 year ago: 420.83 ppm
Weekly value from 10 years ago: 397.65 ppm

Weekly average CO2 at Mauna Loa I accessed this page this morning, August 3, 2024.
That increase over the ten year period is the second highest ever recorded at Mauna Loa CO2 Observatory. To repeat, the second highest, with the highest having occurred earlier this year, in 2024.
People lie, to themselves and each other, but numbers don't lie.
The planet is in flames. I guess the reality, in my opinion, of "no nukes" concerts extends and puts new meaning to "fiddling, while the world burns."
By the way, I think Bonnie Raitt is a great musician - I love her music - but I would not agree to place her in the pantheon of great ethical giants.
Have a great afternoon.
