George Monbiot is actually spot on.
Apart from used chip fat, there is no such thing as a sustainable biofuel.
OK, so he blathers around about peak oil etc, but on the biofuels point he\’s entirely correct. As a number of people (ahem) have been saying for some time. We might be able to get somewhere with algae, we might not, but all of these other methods make the problem worse, not better.
The lesson being of course that we rather need to stop governments trying to pick winners, stop them mandating technologies that must be used. They\’re clearly incompetent at it.
