Mark 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.”
Biodiesel is not a solution. It is politics, it is spin, it is agribusiness profits, it is a hobby.
By Mark Harrison
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.

There are always going to be people who look at any situation and all they see are impossibilities. They would have us all believe that it is far better to just throw our hands up in the air and give up. Can’t tell us what the solution is, just that biodiesel isn’t it, huh?
What does the number of liters of food oil consumed verses the number of liters of fuel oil consumed have to do with anything. Are you suggesting that farmers aren’t capable of producing anymore than what can be consumed as food? Considering the fact that our government pays farmers not to produce crops, I don’t hardly see how that can be true.
And also have you taken into account new technologies such as biodiesel from algea?
By the way, in this country soybeans are raised primarily for their protein content and the oil has traditionally been a less valuable byproduct.
how many acres of land sit unused in the US? Gov. Subsidized farmers, let the land sit because we over produce common crops like corn, wheat, etc.
if every American ate one less hamburger a week, how many acres of land would be freed to grow fuel?
How would millions of acres of hemp forests on US soil add to the problem.
chris agraham… you are a idiot.
