Is hydraulic secondary and residual energy?

Hydraulic energy can be classified into primary, secondary, and residual energy. Primary hydraulic energy refers to the energy available from water in its natural state, while secondary hydraulic energy is derived from the potential energy of water after it has been harnessed through systems like dams or turbines. Residual energy refers to the remaining energy that is not converted into useful work or electricity, often lost as heat or other forms of energy dissipation. Thus, hydraulic energy encompasses all these forms, with secondary energy specifically related to the energy harnessed from primary sources.
