Reduced Ethanol??

On November 15th 2013 USA Today came out with an article explaining the changes in recent Ethanol use regulations and how this once championed bio-fuel law of 2007 has not been working as had once been expected.  In fact for the first time, officials are planning to reduce the amount of ethanol in the US's fuel supply.  At the beginning, the law had hoped to address climate change concerns while encouraging homegrown bio-fuels that would burn cleaner than gasoline.  The ethanol cut back, would require approximately 3 billion gallons less ethanol to be used.  The variable that had not been considered during the initial bio-fuel discussions, was the possibility for such fuel economy improvements as what has taken place over the last several years.  "Bio-fuels are a key part of the Obama administration's 'all the above' energy strategy, helping to reduce our dependence on foreign oil, cut carbon pollution and create job," stated EPA Administrator Gina McCarthy.  This proposed ethanol reduction could bring some flack, when reflecting on statements of the past.  In addition the ethanol mandate has caused quite a stir amongst both oil companies and environmental groups.  As the market continues to fluctuate and technology undoubtedly progresses, what will be the future of bio-fuel vehicle use?
