The ethanol production tax subsidy is 51 cents/gallon http://www.taxpayer.net/TCS/wastebasket/environment/2005-07-01drunkonethanol.htm
The corn farmers (not just ethanol) get billions every year: http://www.ewg.org:16080/farm/progdetail.php?fips=00000&progcode=corn
The break-even cost for ethanol is about $5/gallon: http://www.safehaven.com/article-5010.htm based on the price of corn and processing (doesn't reflect how increases in energy prices will affect the corn growers).

I'm aware of the subsidies for corn growers but wondered if you have any info regarding subsidies for the production of oil in tarsands and shale. I'm under the impression those are market driven but the govt may provide subsidies in the form of tax breaks etc.
