It would be nice if we knew what constituted "rejected" when they were making the diagram. Are they taking into account Carnot efficiency, line loss, the efficiency of light bulbs to create light instead of heat, does heat loss from light bulbs count as waste in the winter time when the heat is a desirable side effect, etc.. We can guess what rejected energy meant when this was drawn (presumably, Carnot efficiency was taken into account, since that's the most probable explanation for the very low efficiency of transportation), but it's hard to interpret without knowing for sure. (I assume the LLNL has a document somewhere that breaks this all down, but it would be nice to have more details in the article.)
