One of the points that people raise in regards to alternative fuels is the work required to produce a given unit of fuel.
How much does it cost to produce a gallon of gasoline? A gallon of diesel?
Now, how much does it cost to produce enough of the alternative fuels to do the same amount of work as a gallon of gas or diesel?
Where's a good place to start looking?
