Let's take my 10% figure. I mentioned both ethanol *and* biodiesel so let's say
contribute equally. So you want 5% x 26.5 quads of ethanol = 1.325 quads.
That's 4 times what
Brazil's producing. A challenging task but do you really believe it's not
do-able long term ?
Especially with cellulosic ethanol production too ?
Additionally, I'd hope that overall gas consumption might actually drop in the
long term thus
making the target easier to hit. If it doesn't drop it begs a few serious
questions about the
long term viability of US energy policy !
Incidentally I gather that Brazil's offering to sell fuel alcohol to the USA.
Nowhere did I say
that imports don't qualify.

Seems like a good time to look at it then.

Is no oil used for electricity generation in the USA ? It affects overall
demand for oil.
