I'm writing a report on alternative fuels to replace petrol/gasoline or airline fuel this weekend, and was wondering if anyone has any special knowledge in this area, and could either point me in a certain direction, or could just share some ideas on this subject.
I'll post my findings when I'm done, but not my report (I don't want to get disqualified from my A Levels

I don't want people to do it for me, but some nice info or links would be very very very well appreciated

The question or title of the report is:
Do we have a viable alternative fuel source ready for when the oil runs out?
