Morphology
The phrase is a straightforward noun–noun compound where 'energy' (usable power) modifies 'efficiency' (effectiveness or minimal waste), so the combined meaning — using less energy to achieve the same result — is directly derivable from the constituents. This compositional pattern is common cross-linguistically and follows basic English word-formation, so a B1 learner who knows both words would very likely understand the MWE.
Etymology
The term energy efficiency comes from the idea of doing the same job while using less energy. Imagine a light bulb that gives the same light but uses less power, so 'energy efficiency' means 'using less energy to do the same work'.
