Cheap food is not so much the issue as enough food.So the end of cheap oil will also be the end of cheap food.

Not for all uses of petroleum. Fuel for vehicles is only one relatively minor use. So many other important parts of modern civilisation require products derived from petroleum.Ethanol can be substituted for petroleum
Most of what is said re alternatives is a triumph of wishful thinking over science.loakglen said:Ethanol can be substituted for petroleum and is completely sustainable. It emit half the nasties of petrol (still CO2 I think) and is easily manufactured. In Brazil they already use an 85% ethanol blend. Basically all that needs doing is to use something other than oil to make it burn so you can see it and its a great source of fuel. How those energy stocks look now?
Epsilon said:Loakglen, from what I have read, the maximum safe ethanol/oil blend is no more than 30% ethanol. Above that level the engines appear to be adversely affected.....
As for Brazil....Whoa...Those cars must be the....happiest cars in the world, after consuming so much "intoxicating' ethanol!

Do some research and find out how many mill barrells/day of petrol/diesel we burn in Oz. Then find out how many acres of cane or sorgum we would need to plant to replace this. Then calculate how much diesel we would burn to produce that cane. Then add the acreage needed to produce that ethinol to your first figure. Do you see the problem?

Hate to get personal but you probably failed in logic too.mime said:Please excuse my English. I got 26/50 in the exam.
You're right of course. Mime has the right to post as he wishes. But I reserve the right to ask for sources.Epsilon said:Han...Please don't be so austerely harsh on Mime...He has not perpetrated a crime that deserves such a severe criticism......
It is (after all) his inalienable democratic right to express himself in whichever way he choses fit to do so, as long as he does not insult anybody......
