Without having recourse to the full thesis you have quoted, I have to assume that the writer is asserting that under the current regime, any fuels produced will not stack up in terms of economies, real or manufactured. This could be largely due to the usual dysfunctional geographical patterns of market distribution, or even because of the unfair advantage paid to the industry by governments subsidising mandated production quotas (some places, for example, Texas, are already proposing rolling back these earlier knee-jerk manoevers).
The concept of regional production/consumption is what they should be mandating, if they are going to mandate anything at all. That would be a very different economic proposal. Otherwise, the end result will be only an anomaly...and will achieve the very thing they are trying to avoid.
Cheers

A 2007 Report on Biofuels using Emergy Analysis:-
https://drum.umd.edu/dspace/bitstream/1903/6671/1/umi-umd-4130.pdf
INTEGRATED ENERGY, ENVIRONMENTAL AND FINANCIAL ANALYSIS OF BIOFUEL PRODUCTION FROM SWITCHGRASS, HYBRID POPLAR, SOYBEAN AND CASTORBEAN
The report concludes:-
"In summary, it was concluded that neither cellulosic ethanol made from switchgrass nor hybrid poplar feedstock, nor biodiesel made from soybean or castorbean, can be a primary source of liquid fuel that substitutes for petroleum-based fuels. Rather, their production is an energy consuming process that provides a means to convert stocks of water, soil, coal, natural gas, and electricity into a liquid fuel that is highly demanded by Americans for transportation. With marginal to negative net energy yields, the current political push to subsidize "biofuels" like switchgrass ethanol will only accelerate the rate at which the nation depletes its endowment of coal, natural gas and uranium."

I am wondering what attention is being given to native grasses both as grain substitute (ie native millet) and also
as potential biofuel.
Also jerusalem artichokes, ditto, a multi-use species..
Sorghum is also mentioned below as a biofuel...high cellulose contaent.
It is a defining permaculture principle to have multi-use plants.
There are also the usual references to hemp below.
If nothing else it will be a more diverse agricultural landscape in the near future...
Australia could certainly benefit from that!
