“Comparing max wind capacity to actual outputs from dams is nonsensical. Wind typically produces 30% or less of its max capacity over any period of time and it does so unreliably. The energy from damns is much more valuable.”
Sure hydro powers well with wind and solar, but a dam can still be overall a bad thing. And I say this as a guy who grew up next to a dam which is one of 12 dams on that river and I don't have a problem with any single one of them.
Building structures that guide rivers is never a thing where the thing you did decades ago will turn out to be the most clever, most efficient and environmentally best solution. That means people who live with and around rivers have to be able to adapt their plans to what they learned. And sometimes that means realizing a particular dam in a particular place does more harm than good, while this is the polar opposite for some other structure.
