I don't know; you tell me.  That is what I am wondering.

I see it as keeping jobs in the US and being self-sufficient, without
getting into politics.

Domestic drilling would be a significant start, wouldn't it?  If it is true
oil is a renewable energy source then why not use it?  I am all for finding
new energy sources but I don't see a problem with this one.  What energy
"problem" are you referring to?

I guess I don't understand what you are saying then.  An engine that can run
on E85 can run on just ethanol or just gasoline, from my understanding.  My
understanding is that ethanol itself is less efficient, so if an engine
using just ethanol was as efficient as a gasoline engine, then running
gasoline in that engine would make it more efficient.  Again, I am not
completely sure about this.

Ok, I forgot to add in the other sources.

I could accept that as a possibility.  However, it is also true that
switching to anything like this is going to have more of a negative
environmental impact until it fully changes over, if the change over is
proven better for the environment.  In other words, it's ok to damage the
environment more as long as the end result is better on the environment.  We
can project all we want but we truly will not know until it happens.
