The government mandated blend of ethanol in every gallon of gasoline is a full-fledged disaster and neither Congress, nor the Environmental Protection Agency shows any indication of either repealing or abandoning it.
The original law mandated the use of one billion gallons of cellulosic fuel in 2013. This may have been the worst government forecast in history. Even with taxpayer subsidies, total cellulosic volume in 2012 was about 20,000 gallons. The government was off by a mere 99.9%.
