Is ocean energy the same as tidal and wave energy?

Answer 1

Tidal energy refers to energy from the changing tides of the ocean, and wave energy refers to the energy carried in oceanic waves.

Ocean energy is a very vague and incorrect term, although if you have heard it, it probably refers to those. There is lots of energy in the ocean, and to say ocean energy would be pretty ignorant. There is also energy in its living creatures, in its temperature differences, in the currents that affect global weather patterns. There is also energy in all the chemical bonds in every molecule of every single thing in the ocean that we simply choose to overlook.
