Canada is second-largest country by area, occupying around 6.5% of Earth's land surface. It's only 37th by population, with 0.5% of world's population. It's very non-representative example.

No offense, but Canada isn’t relevant on the global scale.

Hydro use is growing, especially in developing countries. However it’s a shrinking percentage of total energy generation. There is an absolute cap on theoretical hydro energy production, and it isn’t enough.

Hydro is low carbon and renewable. But it isn’t green, and it’s not enough.
