"Energy"? Or "environmental externalities confounded?" Energy prices
do vary around the world, but not by a huge factor it seems: witness
the Bitcoin "factories" looking for places with cheap energy access,
as energy costs take a significant part of total costs), while
foundries don't seem to follow that pattern. OTOH other ecological
externalities do vary *a lot* -- rare earth metals being a sobering
example.

Yes, more transparency here would be something, wouldn't it?

My feeling too...
