To add to the ongoing debate over the merits (at the moment) of using pure petrol vs 10% ethanol in petrol or just concentrating on EV tech, Jason Fenske over at Engineering Expanined (YouTube) has produced a new video which refers to a new study that suggests biofuels aren't the 'greener' alternative to pure petrol, or at very best (i.e. ignoring the new findings and going on the old data) around 2% better over a near 30 year period.

Yes, this pertains to the US and using corn, but it may have an impact in many other parts of the world that have been changing over to E5 and now E10.
From what the study looked into, I found it amazing how supposed 'experts' from the EPA etc did not take into account the huge and long-lasting effects of changing over land usage to grow corn to make biofuels.
