Hydro does rule. Top 8 power stations are hydro right now. And the top power station has been a hydro for over a hundred years now. Very cool! Three Gorges has capacity of 22.5 GW.
I really hope nothing bad happens at the three gorges dam. There's nearly half a billion people that would have to be evacuated, and tens of millions who likely wouldn't be able to evacuate in time due to proximity.
I'd rather live near a modern nuclear plant myself.
