energy-consuming

The compound adjective "energy-consuming" is a modern English formation that transparently combines its constituent parts. The noun "energy" originates from the Aristotelian Greek concept energeia, denoting "activity" or "being at work," which entered scientific English via Latin. The verb "consume" derives from Latin consumere, meaning "to take wholly" or "devour." The suffix "-ing" is a native English participial ending. The literal, compositional meaning of "using up activity or power" maps directly to the modern abstract sense of requiring significant input of physical, mental, or electrical energy, reflecting a logical and efficient word-formation process in technical and everyday language.
