The only problem with that point of view, is that every energy
transformation and use carries a penalty of a percentage of the energy
being
lost.

If the penalty is less than the gain, it's a win. There is a penalty
for producing electricity on the edge of town and wiring it to your
house vs. having your own home generator. Most of us decided that the
gain of using municipal power outweighs the penalty of having to pipe
it to our house (in which it losses power in the transit).

I guess I didn't state what I meant well enough.



You take some hydrocarbon and burn it to make electricity, you lose some in
waste heat. You take the electricity, and pipe it somewhere, and you lose
some in line loss. You take some of that electricity and put it into making
hydrogen, and you lose some more, or store it in a battery and lose some of
it that way. You use the electricity to make a car go, and you lose some
of the electricity to heat, again, or by burning the hydrogen.

Loss energy due to efficiency is inevitable.

But if the gain in efficiency is more than the loss, who cares. Its not
very efficient for me to run a Honda generator in my backyard so I
choose to hook up to the power grid, even though there is power loss in
delivering power to my house.
