If you are claiming (it's a bit unclear) that tidal energy is a derived

No. I admit to a gross over simplification there.

Tidal energy is derived from gravitational potential energy and/or
the kinetic energy of the earth/moon/sun system. I think describing your
remark as an "over simplification" is being a bit optimistic.
