Is that the case for all Hydro? Or only for specific types of Hydro applications?
I am curious to understand the different technologies. I am also asking because in the end every kind of power generation will have some effect on the ecosystems. It's always a question of trade-offs.
River ecosystems are really complex and far-reaching. It's about more than just fish swimming upstream to spawn.
Hydroelectric dams destroy these ecosystems completely. Yes, you can build bypass channels for fish, but that's just a part of the system and the channels don't work properly in many cases.
