Although hydro electric is a very good source of power due to the high density of water and doesn't have some of the theoretical limitations wind power has, it is very very obstrusive to actually extract power from it. The dams that need to be built pretty much change the entire ecology of plant/animallife in regions where they are built. Not to mention these are massive projects. Also many areas just don't have access to actually extract power from water from what I can see. Its not as simple as sticking a photovoltaic on your rooftop (which in itself is unreliable in many ways).
The only form of power that I can personally see replacing fossil fuels on lare scale in the future is nuclear fusion but that always seems to be 20 years away no matter what era you live in.
