The USDA claims 3.2 units for 1 unit input for biodiesel from soybeans.
The report does not show how this is determined. UNH claims higher
production from alga; again not well supported. In either case about
10% ethanol or methanol is needed for the final biodiesel production.
Growing soyabeans to produce biodiesel would require all of the
available arable land; as a minimum, it would probably require more.
Using arable land to produce fuel is dumb, within a very few years all
arable land - and more - will be needed for food production. Alga
production on non arable land may be feasible but only if
ethanol/methanol can be produced using non arable land.
The amount of arable land in the US is likely to decline dramatically,
both because of home building and oversubsidized water absurdities in
the West.
