I'm very much with you on this. Increasing standards of living are directly tied to a decreased cost of energy. Aside from property absolutely everything can be decomposed into physical or mental effort — energy [omitted at suggestion of follow-up, merci!]. The industrial revolution allowed the substitution of wood or coal or uranium or PV cells for food that powers oxen, horses, and humans.

>energy (or energy * distance aka work)

Your comment would be improved by omitting the words in parentheses: work is force times distance, and energy and work have the same dimensions (namely mass * distance * distance / time / time).

(I agree with the rest of your comment.)
