yes, that's true.
just look at how food prices have gone up since people suggested corn oil as a possible source of bio-diesel...
apparantly people using food crops as petrol replacement drives up the cost of food, (since food crops are being used as fuel!) -who'd have thought!!
now aparantly they are looking at other kinds of crops as dio-diesel,
1st generation bio-fuels -i.e food crops that can produce oil like sunflowers or corn, are not a good choice because they contribute to world hunger...
and really who wants to drive whilst someone else starves
so now they are looking at second generation bio-fuels, these are normal plants where they onvert the plant cellulose into a fuel source. the only problem that they have is that a lot of fuels, whilst carbon neutral at the end stage, take energy to grow, (thought that energy is normally free (like from the sun), but they also take water to grow. and that water that is being used to irrigate fuel crops is adding to world water shortages!
as I drive to work everyday and look at the verges, I can't help but wonder whether grass based plant cellulose second generation fuels would be a good source for biodiesel, I mean grass grows completly unattended, it doesn't need watering, and we have to pay to cut it anyways.
