Agriculture is one thing this country has done well historically. It turns out, without a huge amount of hassle, we can use that agricultural prowess to “grow” our own fuel. Sound crazy? Perhaps, but something that’s happening today. In 1999, 500,000 gallons of biodiesel was produced in the US. In 2005, the volume was around 75 million gallons.



So what is biodiesel (mono alkyl esters) anyway? It’s a product of vegetable oil, methanol, and lye put through a process called transesterification. This yields usable fuel and a glycerin by-product. Turns out, it’s pretty trivial to produce on your own, there are many step by step guides, but this one is the clearest and most complete in my opinion.

Biodiesel works in any standard diesel engine and can be (and is) mixed with petrodiesel to get different properites. For instance, biodiesel is more viscous than standard petrodiesel and is more temperature sensitive (if you’re in the cold, you want a bio-petro mix most likely.) This fuel is for sale in retail locations with ratings like B20 (20% bio) to B100 (100% bio.)

With the crunch on fossil fuels, wouldn’t it be great if we could simply grow our way out of this mess? Here’s a great FAQ on the fuel.
