“The article refers to “work” energy. Not “heat” energy.”
Ahhh, since when was there a difference?

You caught that. You know your physics.
However in the authors context he means directed useful mechanical energy not random energy dissipated as useless (heat). On a macro scale he makes sense.
Work = Force x mass x acceleration x distance. But work's byproducts are wasted energy, thru friction etc.
