I must admit I am unsure if coal and ethanol can be used as plastic precursors or plastic production in any way (in the case of ethanol I would be very surprised), but I reckon that we can be sure of one thing - the energy requirement to get anything useful out of coal will be huge.

Think Canadian tar sands - its hard enough to converter this stuff to anything useful.

Ethanol is another one of those things I think we use to fool ourselves, as it is energy negative throughout the process. I cant see us using anything so valuable for a few plastic items!

Indeed- transportation via trucks and tractors burning diesel to plant and harvest it, electricity used in the conversion of sugar to ethanol (although I currently have 23l of apple cider doing just that without using any power :) ), so it really makes me wonder why they add it to petrol to make E10 and call it a "green" alternative.

I'm sure it has absolutely nothing to do with a certain businessman being mates with the previous PM.

Won't we still need some stocks of oil to provide the lubrication to moving things?... axle grease for the horse and cart ? ;)

I guess rarity will just jack the prices up astronomically.
