Etymology

From Middle French énergie, from Late Latin energia, from Ancient Greek ἐνέργεια (enérgeia, “activity”), from ἐνεργός (energós, “active”), from ἐν (en, “in”) + ἔργον (érgon, “work”). The sense in physics was coined by English polymath Thomas Young in 1802 in his lectures on Natural Philosophy.
