American energy use, in one diagram

``Every year, LLNL produces a new energy flow chart showing the sources of US energy, what it's used for, and how much of it is wasted. If you've never seen it before, it's a bit of a mind-blower... Perhaps the most striking feature of the spaghetti diagram -- what everyone notices the first time they see it -- is the enormous amount of "rejected" energy. Not just some, but almost two-thirds of the potential energy embedded in our energy sources ended up wasted in 2016.''
