In digging out all that land, you'd expend more power than the hydro would generate back.
It's not about generating power, that's just an addition to it, the whole idea is to prevent sea level rise, sea level rise that will kill millions of people and destroy the Netherlands.
Okay, but I'm just noting that your suggestion about generating power is not an advantage.
I mean that you're merely displacing a large amount of water from one place to another. To lower sea level, you have to flood somewhere else. You don't gain any total land area, but you do lose a lot of existing land that has potential use... if it's not already in use. Hope there are no people there already! Maybe they can move to the Netherlands.
The only thing you'd accomplish is to mess up a lot of existing infrastructure and destroy a lot of wildlife.
Are you kidding, the new rivers and estuary's will be a new place for wildlife to
thrive.
After you destroy the wildlife that was already there. This is all right with you?
Besides, what kind of new wildlife would thrive around a river full of
salt water?
