^^^ I didn't quite understand your point number 2.... As all ethanol made here IS made out of sugar cane... I would all ethanol that is made comes from sugar cane, but you mentioned an alternative to ethanol was sugar cane,,, so i'm guessing that the ethanol your refering too that is used in the states is made with something else more expensive??
I honestly thought ethanol was made form sugar cane full stop as that's what makes it cheap...

Check this out for SHITTTEEE, our city has an LPG gas rig about 20 miles out on the coast...
They pump millions of litres of it a year.. It costs the consumer 43cents per litre Australian to fill up at the pump, but OUR government sells it to china for 2cents a litre... If we want to talk about why the filling of our cars is so f'n expensive, we need look no further than our own government.
