Hydro is just more extracted energy Jed. It's impossible to create with it same as any other energy from the planet, it has to be direct or nearly direct solar to have the magic effect of net creation, reduction of entropy / temperature.
Anybody not mathematically signing energy to start with, has no chance of finding a truly sustainable, creative solution.
What you've said there applies to wind, and hydro, they are a distraction from plugging into the only source that can charge the battery of Earth.
If you don't understand that, how can you be so sure you know the future? :)
