Monbiot wrote a Guardian story on what we all suspected: "Worse Than Fossil Fuel":
The last time I drew attention to the hazards of making diesel fuel from vegetable oils, I received as much abuse as I have ever been sent by the supporters of the Iraq war. The biodiesel missionaries, I discovered, are as vociferous in their denial as the executives of Exxon. I am now prepared to admit that my previous column was wrong. But they're not going to like it. I was wrong because I underestimated the fuel's destructive impact.
Before I go any further, I should make it clear that turning used chip fat into motor fuel is a good thing. The people slithering around all day in vats of filth are performing a service to society. But there is enough waste cooking oil in the UK to meet one 380th of our demand for road transport fuel(2). Beyond that, the trouble begins.
I often must bite my tongue to avoid criticising people who extoll the virtues of their Peanut Cars, some old rabbit which they load up with vegetable grease and anti-coagulants.
"It will soon be competitive with gasoline at these prices!" they say, and everyone clucks their tongue and nods. (I live in is Seattle. Not sure how this conversation would play out in the red states.)
Sadly, the goal of bio-diesel being competitive with gasoline will be just perpetually out of reach, like a carrot on a string. The actor yanking the carrot should be understood to be (fossil) energy prices; as Monbiot points out above:
