Ultimately, hydro power depends on oceans supplying abundant water vapor to precipitate over elevated topography. No oceans, no hydro power. You also need topography: no land, no hydro power.


Sure, whatever. Tidal energy is still not hydro power, but rather a separate thing.


Nobody said tidal power was hydro power. But, for completeness, I will say it now: tidal is also hydro.

It is distinguished from common hydro power by drawing, ultimately, on planetary body kinetic energy rather than insolation.


Well that’s not correct. You can say whatever you want but that isn’t the common definition of the term.


Language is tricky, and cannot be made less tricky without loss of most of its value.
