you have 2.23MM BTU of "potentially available energy" (all from fossil).

At their press release:
Argonne expert addresses energy, environmental impacts of fuel ethanol

There is a short presentation that walks through the comparison of energies required for different fuels. It also compares fuels used for electrical power generation. This makes it clear the 1.23 MMBTU to produce 1 MMBTU includes the BTU of the fuel itself.

This picture helps make it clear. Gasoline takes the least amount of additional energy to process it into fuel.

This is from the link above, the source of the report.

"This makes it clear the 1.23 MMBTU to produce 1 MMBTU includes the BTU of the fuel itself."

Nope. Doesn't say that. Look back about eight slides from the one you posted for the real story.

Says clearly that for 1MM BTU of gasoline, you have to spend 1.23MM BTU of energy, and for 1MM BTU of ethanol, you have to spend 0.74MM BTU of energy.

Besides, YOU were the one who said that the Argonne report was "invalid".
