As has been addressed very well by Jorge and Shaun, given the differing context of those courses and the energy perspective, it isn’t surprising it wasn’t mentioned. I believe a friend of mine in grad school mentioned another book that might have opened my eyes to this perspective earlier, but I was much too busy being dogmatic to track down the book back then. If I weren’t so afraid to visit Amazon (because I always find more books I want than I should buy), I’d order it today.

But, speaking of books ... can I borrow yours when you’re finished with it? :-)
