If 10% ethanol in gasoline is good, 15% (E15) will be even better. At least for some folks.
We’re certainly heading in that direction – thanks to animosity toward oil, natural gas and coal, fear-mongering about global warming, and superlative lobbying for “alternative,” “affordable,” “eco-friendly” biofuels. Whether the trend continues, and what unintended consequences will be unleashed, will depend on Corn Belt versus consumer politics and whether more people recognize the downsides of ethanol.
