Biofuels are generally more expensive than conventional fuels at the moment, especially since conventional fuels already have a lot of infrastructure in place. There are indications we have reached peak oil and while we can expect short term price fluctuations the long term trend is likely to be for them to become more expensive in real terms. Eventually biofuels will become relatively cheaper and we will change over.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
