US energy efficiency falling, not rising

Vox : "It’s important to put this waste in context. It is not mainly about personal behavior or inefficient energy end use — keeping cars idling or leaving the lights on, that kind of thing. That’s a part of it, but at a deeper level, waste is all about system design.

The decline in overall efficiency in the US economy mainly has to do with the increasing role of inefficient energy systems. Specifically, the years since 1970 have seen a substantial increase in electricity consumption and private vehicles for transportation, two energy services that are particularly inefficient. (Electricity wastes two-thirds of its primary energy; transportation wastes about three-quarters.)"
