Morphology

waste + of + energy

The meaning is directly derived from the constituents: 'waste' (inefficient use) + 'of' + 'energy' (usable power), so a learner who knows those words can infer it refers to effort that consumes energy without useful result. The extension to mean a 'pointless action' is a predictable metaphorical shift and is cross-linguistically common, making the phrase immediately understandable to a B1 learner.

Etymology

Waste of energy comes from a simple image: the words waste and energy make us think of using up power like fuel but getting nothing back, like pushing a car that will not move. That's why it means an action that is 'pointless' or does not help.
