Many sources for Biofuels

Reuters has an article from a German Biofuels Conference held last week.

Non-food plants and crops mentioned at the conference as possibilities for use in future biofuels range from corn husks, grasses and algae to jatropha oilseeds, tree bark and twigs.

First generation green fuels aimed at reducing global warming are largely produced from foods such as corn, sugar and vegetable oils and face hot but unresolved controversy about whether biofuel production raises food prices.

The second generation of biofuels will be produced from non-food crops and the conference of global biofuels executives heard that the choices for new generation feedstocks were still wide open.
