diesel price
The stuff is distilled into separate fractions,so you get products with different properties.The lightest would be gas,the heaviest some sort of bitumen sludge.The amount of diesel depends on the source of the raw oil.Diesel is not "made"as such.It is just separated from a mixture of substances -basically.Theoretically it could be "made" from any form of carbon-timber,plastic,sugar,old carpets.A new product is Biodiesel,a diesel made from oil fruits like sunflowers or rape.The EU has sponsored projects to make it from household waste.I think in Ireland they are already separating household waste,dry and shred it,pack it in bales and store it for future use on landfill sites.It could become diesel as well.
But energy prices are not high enough yet to make it commercially successful.The breaking point for most alternatives lies at around 50-100 dollars/barrel crude oil, we are not so far away from that limit.
