Mark Harrison sent this essay to me from the African bush, “Biodiesel is not a solution. It is politics, it is spin, it is agribusiness profits, it is a hobby.”
Soy and canola and oil palm are food, they are not fuel. Do you really want humans to be competing with cars for their food source?
A human consumes on average 20 liters of edible oil a year. 20 liters – around five and a quarter gallons. Per year. How long does it take your car to consume five gallons of fuel? Half a day?
Worldwide, we are consuming around 85 million barrels of petroleum every day – that’s 13.5 billion liters per day. The entire human population only eats around 328 million liters of food oil a day. So, let’s compare: 13,500 million liters of fuel oil consumed every day vs. 328 million liters of food oil consumed every day. That’s 41 times more fuel oil than food oil consumed.
What makes biodiesel proponents think that biodiesel is an alternative to petroleum? How could we possibly increase food oil production by 41 times? Cut down the rest of the mangrove swamps for oil palm plantations? Raze the rest of the rain forest for soy bean fields? Just to run the world on B10 (10% biodiesel, 90% petroleum diesel – hardly an end to petroleum dependency) we’d have to increase plant oil production by a factor of four. That alone would require destroying the rest of our suffering ecosystem, and that type of food oil consumption would likely raise food prices to the point where the majority of the world’s population living on just a few dollars a day would starve to death – the world’s poor simply can’t compete with our cars.
So, the world running on 10% biodiesel = ecological disaster and mass starvation. Not an optimal solution. We’re still dependent on petroleum, but manage to bury the ecosystem and starve billions of people.
No, biodiesel is not a solution. It’s something for a small group of hobbyists. It is something for politicians to make hay off of. It is something for fools and people who can’t do simple math to fall for.
What is the solution – solar? Wind? Nukes? I can’t say, but it is certainly not dreaming that we can farm our way out of this, and the solution is certainly not in wasting our time and resources pursuing this dead end.

I’n not saying either tht you are wron or that I disagree with you but your reasoning is somewhat askew.
I think the biggest threat to food production is ethanol – the fermented variety. Cellulosic ethanol is a completely different animal and uses the WASTE products from many food crops – which is a win-win in my book.
Where biodiesel is concerned, food oils such as palm and soy don’t have the oil content to compete with jatropha and moringa, niether of which is a food crop and both of which will grow happily on land which is unsuitable for other drops with little or no attention between harvests. These plants are perfect for small production of “own use” diesel.
I am an advocate if fossil fuel DISplacement rather than REplacement and I believe whatever we can achieve is better than sitting in the stands complaining.
Electricity and hydrogen will be the main fuels for transport in the future. There will only be dinosaurs like me still running old internal combuston diesel engins in home-grown fuels.
Keep up the good work!!
