The number of places where you can build a dam is limited, and when you find one it is not unlikely that you have to relocate > 1 million people to build it (Three Gorges Dam). That is on the other side of the scale you are talking about.

The point is about making a comparison. When Bitcoin's energy consumption is equaled to that of a single dam, it just doesn't seem that impressive.
