Yes per capita. Per capita is what matters. No country gets a free pass to do whatever they want just because they have a lower population. Per capita is literally what matters.
Imagine it this way: The US cuts carbon production by two thirds. What do you think the response would be? You'd never hear the end of it. How great the US is. How awesome the US is. How the US is responsible. How the US is not only taking charge, but how they've put their money where their mouth is and has succeeded wildly because they just cut their carbon by two fucking thirds. How awesome is that. How everyone else needs to get on the level of the US. How the US is the savior of everyone and everything. Etc etc etc. Guess what? China is already there. And the response? Crickets. Worse than crickets actually. They are horrible. They are responsible. They are everything that is wrong on the planet. They need to do more. The world can't wait, they need to act. Like fucking what? The difference it seems is that people don't understand, wait for it, per capita.
Or put it a different way: Do you think Americans have a god given right to pollute 3 times as much (because you know, per capita) just because they are Americans? Just because the US population is smaller overall? Yeah nuts to that I guess, 3 times for us USA USA USA.
Having spent an inordinate amount of time on google earth looking at the topography, those look like tiny dams. They were not holding back any significant amount of water. They're almost run of river (run of river generation just uses the natural water flow).
(Note even with the small amount held back they could generate a lot because of the steep terrain creating a lot of pressure head, so don't go comparing the wattage to other dams.)
