Hello Wildstoic,

In your additions to the "cellulosic ethanol" article on 27 January 2007, you state:

"In his State of the Union Address on January 23, 2007, President Bush announced a proposed mandate for 35 billion gallons of ethanol by 2017. It is widely recognized that the maximum production of ethanol from corn starch is 15 billion gallons per year, implying a mandated production of some 20 billion gallons per year of cellulosic ethanol by 2017."

Actually, this is a misstatement of what Bush actually said:

"To reach this goal, we must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in 2017..." (http://www.whitehouse.gov/news/releases/2007/01/20070123-2.html)

"Renewable and alternative fuels" is a category broader than just ethanol. It certainly includes biodiesel (explicitly mentioned by Bush in the same speech) and arguably also includes hydrogen produced from processes that do not require fossil fuel feedstocks, such as electrolyzers powered by green electricity or one of several processes now being studied in research laboratories that produce hydrogen more or less directly from sunlight.

The arithmetic in the second sentence no longer applies until we know just what the percentage breakdown of the various renewable and alternative fuels alternatives is.
