Morphology

energy-saving + light

The meaning 'a light that uses less energy' is directly and compositionally derived from 'energy-saving' (saving energy) + 'light' (a bulb), so a learner who knows the constituent words can infer the MWE. This adjective+noun compound follows common morphological and semantic patterns in English and many other languages, making it immediately comprehensible to B1 learners.

Etymology

The name energy-saving light comes from a simple picture: a bulb that 'saves' energy while still giving light, like a lamp that uses a small amount of power instead of a lot. That's why it means a bulb made to 'use less energy' and so lower your electricity bills.
