There isn’t enough hydro potential on the planet to produce the amount energy we need. It’s also worth pointing out that while hydro is renewable, it isn’t clean. Dams are ecological nightmares. Hydro will like be part of our energy profile indefinitely. But it will never be more than a small fraction. And in the long run that fraction will get smaller as global energy demand continues to grow.
