Bio-diesel

I did some research into fuels recently because of all the recent backlash against bio-diesel. What I found was striking to say the least.

Seed Stock/Oil Yield in pounds per acre

Peanut/764

Canola/600

Rapeseed/600

Safflower/600

Soy/600

Linseed/350

Corn /200

Cottonseed/200

This data was derived from 

Buchanan, G. (2010). Increasing Feedstock Production for Biofuels: Economic Drivers. BRDI , 3.

From the data above it's plain to see the largest yielding conventional crop currently grown in US soils would be peanut.

The basic idea of growing crops for fuel instead of food could be considered a bad thing in and of itself, it's definitely a bad thing to grow a conventional food crop which produces a very low quantity of oil as an oil crop. Yet this is exactly what the US farmers are doing. Corn is the lowest yielding crop that could be planted for fuel.

Under the current methods of production I cannot endorse bio-diesel. I thought I'd be the last one to encourage government involvement in private industry, but the bio-diesel market needs to be regulated. Corn needs to be taken out of the Feedstock for bio-diesel production. 

However there is nothing wrong with using waste oil of any kind as fuel be it corn, peanut, soy, animal oils even. Most of these are low in emissions and have a high energy output. I'm personally inclined to purchase land and become a peanut farmer for the production of bio-diesel myself. The yield being nearly 4 times that of the corn farmer, the comparative advantage is astronomical.
