Sugar cane more efficient:

Corn ethanol generates less than two units of energy for every unit of energy used to produce it, while the energy ratio for sugar cane is more than 8 to 1. With lower production costs and cheaper land prices in the tropical countries where it is grown, sugar cane is a more efficient source.

Just food for thought:  We are providing huge subsidies for US corn ethanol producers and placing large tariff’s on Brazilian sugar cane ethanol which is much more efficient.  This is a direct result of the farm lobby at work.  Unfortunately my party is on the wrong side on this issue.  Obama supports this policy even though it makes little sense.  With the recent mid-west floods causing massive crop losses we are going to see corn prices soar in the next year as the government continues to push so much of it into ethanol production.  I’m not a McCain fan but he is right on dumping these subsidies and dropping this tariff.
