Only about 30% of the energy in gasoline is converted to useful work in a gasoline car (the 'make metal box go forward' part). The remaining 70% is Rejected Energy (the steam you see going out the tail pipe in winter).

Which (not sure if you did this intentionally or accidentally) brings up an interesting point on the parent comment and the LLNL sankey:

> It's always worth remembering that electricity only accounts for ~20% of global energy consumption (in the US it's closer to 33%).

That "global energy consumption" figure includes a lot of Rejected Energy going out tailpipes and smoke stacks turning burnables into electricity. A secret bonus of wind and solar is if you produce electricity without burning things, you actually decrease the energy demand! If you're not losing 70% of your energy consumption to the Rejected category, you suddenly need a lot less total energy.
