Biofuel is a small industry. But the big difference is it's carbon neutral because the carbon released into the atmosphere came from the atmosphere.

Oil is releasing carbon from prehistoric atmospheres.

Actually it is tax neutral, not carbon neutral. The kicker here is (i cant find the source anymore) at least in Germany agriculture is energy intensive. It seems one energy unit of crop need one energie unit of (tax excempted) fossil fuel (for the machineries).

So basically you are pumping fuel into a black box, and out comes bioful (which has tax breaks as well, if I remember correctly)

It is a left picket right pocket game.

That's true, one must also account for the carbon footprint of the inputs. Of course oil extraction and refining also has a carbon footprint.

It's a problem that could be solved over time if using green energy for the agriculture.
