I find it hard to believe the eager pursuit of ethanol by Governments given the total inefficiency of the system. Conventional oil yields 10 barrels of oil for every one barrel burnt to extract it. Ethanol yields (optimistically) about 10 barrels for every 8 burnt producing it.
How can we reconcile this with a global population that is growing fast - adding the equivilent of another N American population every 6 years? Where will the land come from?
Global oilseed production (canola,soya etc) is currently 400 million tons.If this all were converted to biodiesel it would only supply about 16% of the worlds diesel consumption. Even if the entire corn and wheat crops of the world were turned over to ethanol it would not supply one third of the world demand for gasoline.
We have absolutely got to smarten up as a world community - this SUV culture is unsustainable and we must start to do something about it. And it will need to be something a lot smarter than producing ethanol from food crops.
