Can hydroelectric power completely replace current methods?
Hydroelectric power is already one of the current methods and has been for well over 100 years. No it cannot completely replace other means of generating electricity. For one thing most western nations have already maxed out their usage of hydroelectric power and some have actually had to tear down some older dams due to environmental damage caused by the dam. Rivers that can be economically dammed to generate power are a very limited resource.
