But the article says that he only favors ethanol as a stopgap measure until ethanol can be sourced from other sources.

For example, Coskata's cellulosic ethanol process is significantly more energy efficient than corn ethanol processes. There is also a cellulosic diesel fuel process which will be demonstrated with a 20 million gallon per year plant starting up here in the U.S. this month which could prove to be a major breakthrough in energy efficiency.

The support for corn ethanol is really limited, and the support for cellulosic biofuels is enhanced, by the Renewable Fuels Standard which was required by the Energy Bill that was passed last year.

Robert Rapier has written on this -extensively !

I suspect you are not impartial:"cellulosic ethanol process is significantly more energy efficient"

Hmmmm hope to hear from you when you have some hard production data.
