Currently in France we have E85 (85% ethanol and 15% gasoline) but only few gas station are selling some. The ethanol comes from sugar beet.
All the diesel has at least 5% of diester from rapeseed. Very few biodiesel are sold, it's mainly used in buses.
iirc to convert all gasoline to Ethanol, 7.5% of all French cultures should be converted to sugar beet. If currently the price of sugar, done from sugar beet in France, is constant, it may not be constant if Ethanol is generalized.
We have enough fertilizer, pesticide and water problems without adding so much more intensive culture.
