It is a relief that Environmentalists have decided that hydro counts as "renewable" energy! When I was in school, hydro was considered really bad for the environment, and projects like the Hoover dam and Yangzie River dam were "not helping"

Many environmentalists seem completely unwilling to acknowledge the concept of tradeoffs. Unless a solution is 100% perfect in every way, they reject it. Or at least, the committees and infighting become so protracted that they cannot agree no a solution. This is true of our world today. We have limited resources with which to address things like pollution and emissions. We should be focusing on the most impactful changes first, posing the fewest costs. Nothing has zero cost.
Reminds me of when Bjork was protesting the construction of a new hydropower plant in Iceland, when the Director of Iceland's National power company (behind the project) was actually her uncle. I used to be romantically involved with someone in his side of the family and noticed Bjork was conspicuously absent from any family gatherings he hosted, of which there were many.
They certainly can be disastrous in ecological terms, and will disrupt all biotopes along the concerned water flows.
But it's extremely renewable none the less.
