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? >Yeah, that's what I was trying to say.

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. >Huh? Are we maybe talking about two different things here? I heard >electric vehicles, solar, wind, photovoltaics and nuclear. Where did >E85 come in?

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.
