Difference between Biodiesel and Ethanol

May 8, 2007

I’m just trying to learn the basics here. 

 Ethanol is alcohol based and can be produced from a wide variety of plants, most famously corn.  When added to gasolene, octane levels are increased and the fuel burns more completely (which is good for the environment).  All gas burning cars can use.

Biodiesel, in contrast, is a fuel derived from a wide variety of oils (e.g., vegetable oil, animal fat).  You need a diesel engine to use.

That’s my high level/simple definition for now.  More info at wide variety of sites such as TreeHugger.com.
