Terminology: hydro/wave/tidal
Hello everyone. I'm not an expert on renewable energies, but I'm doing a translation on this topic. In my text, water energy is divided into hydroelectric, tidal, and wave energy. I was wondering why tidal and wave are not considered hydro power as well. Apparently hydro is only run-of-river and reservoir. Is there anything I'm missing regarding terminology? Thank you
