As of lately there's been a lot of discussion about wether biofuels are doing more harm than good, and the EU wanting to ban imports of "bad" biofuels. I was wondering just how the fuels compared to eachother, and came across a pretty neat interactive comparison by Nation Geographic.
Unfortunately it only compares a limited amount of biofuels (palm oil is not included, for exacmple), and the CO2 emissions are only related to cost of production and do not take into consideration the clearing of rainforests or NO2 from fertilizers, for example. But still, I found it interesting and wanted to share it with you, give me your thoughts

Overall it's pretty clear that, with the stuff I mentioned above taken into consideration, neither Ethanol from corn nor biodiesel as currently produced make any sense, so rushing headlong into this is certainly not good...let's just hope a smooth tranission to better biofuels is made. Specially cellulose and algae seem very promising. Algae because of the sheer amount that one acre can produce (even the most conservative estimates put the yield at around 20 times that of ethanol from corn), and cellulose because...well...it's everywhere anyways!
