If China were to put strict, California-style controls on pollution, energy generation would get more expensive there, and goods made in China would also get more expensive. That would be an incentive for other countries to manufacture more of their own goods (or find a new, cheaper country to build things in), and certainly China does not want that, so they continue to pollute.

Note that labor would still be cheaper there, so we could still have cheaper stuff, we just want it even cheaper, to hell with the consequences that we don't see anyway.

It's not just energy either, there's various chemicals and safety concerns that people discovered in the west a long time ago. It's just that the allure of cheap stuff is so great, it was fine to just stop making it in the west and pretend that standards overseas were acceptable.

Developing country is developing

I would say your viewpoint there is overly simplistic.

what is going on in China? that they are having such energy production problems? to the point where they are rationing electricity for months now. Where is all this extra demand coming from? and at what point will it peak ?

the excuse is always well the rest of the world got to pollute so we have our turn now.. seems crazy and childish when this will impact us all.

Blockchains?

(More seriously, I guess an awful lot of it is used to keep producing the cheap goods that Western consumers demand. We need to adjust our lifestyles to "consume" much less, in every way.)
