Jim, some things you may not be considering:
Small car engines heat up and cool down every day, multiplied by millions. I take this as self evident. Powerplants do not.
Petrol has to be shipped, and occasionally guarded, and craked, etc. I've never heard of a coal train (or the sun) being pirated.
We cannot compare the current status of the grid with the future possibilities of ICEs. There have been improvements in grid technology too (i.e. HVDC).
Also you are comparing the fuel in a prius tank to a powerplant, ignoring the most painful "and stupid" parts of the ICE equation.
And trebuchet did give us a
breakdown which had coal at 50%, natural gas %20, nukes %20, and ~%10 renewable. so while half the electrons are %33 efficient (from a simplistic viewpoint),
%10 are infinitely efficient (more if you are the type to put nuclear in the mix, but lets not).
Less color words and more facts please. Lets keep it apples to oranges and not apples to juicy peeled and skinned sections of an orange arranged nicely on a plate with maybe a little powdered sugar sprinkled on them
P.S.

I don't agree with those people either. Electricity (energy) aint free, at least not these days. I don't even like ignoring block heaters.
