Morphology
The compound 'energy unit' is directly and compositionally derived from 'energy' (usable power) + 'unit' (a measurement quantity); it denotes a unit used to measure energy with no idiomatic or metaphorical shift. This noun-noun compounding pattern is regular and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the meaning.
Etymology
Energy unit means a standard measure of energy. Think of energy as the power or heat something has and unit as one measuring cup, so the phrase points to a set amount like a 'joule' or a 'calorie' used to measure energy.
