I would support subsidies for actual “green” energy sources, however, ethanol is not one of those sources. Not only is it a net-energy loss (takes more energy to produce than what you get out) but…
“Using corn is the least productive way to make ethanol, at roughly 300 gallons per acre of feedstock. The Brazilian ethanol industry gets twice as many gallons per acre using sugar cane, and other feedstocks like switchgrass have been projected to produce up to 1,200 gallons per acre.”
So now, where is the investment in switchgrass ethanol?
Or perhaps we put a 50 cents / gallon tax on petroleum based road fuels?
