Thread: How Green are Biofuels ?

Ok, this is a US chart, but it makes interesting reading.....

from here Bio-debatable: Food vs. fuel

That's interesting reading.

An important aspect, other than the green one, is the rising impact on third world food prices, due to grain harvests being diverted to bio-fuel production.

The wood residue seems like a good option going by that chart.

It's a big thing to think about. But at least we're starting to think about it - a bit late maybe.
