Context is everything. Not every country is at the same point on the industrial timeline. The UK, US, Europe are post-industrial, and have the luxury to focus on greener energy options. Other countries not so much (yet).
The only reason why those places mentioned can be said to be "post" industrial is because they moved most of the industry to other countries. You can't do that forever, you're bound to run out of countries at some point. Not all the countries can be "post-industrial", the metal has to be smelted somewhere
