In terms of alternative hydrocarbons, the order of what will be used first to last to make unconventional liquid fuels are: 1) Extra Heavy Crude Oil (Venezuela), 2) Oil Tar Sands (Canada), 3) Kerogen Oil Shale (U.S.A.), 4) Humic Coal (U.S.A.) The U.S. has one of the largest reserves of oil shale and coal in the world. Both of these could be turned into synthetic fuels if needed later. Israel which has both large reserves of natural gas (hydrogen) and oil shale (carbon) could use both to make synthetic liquid hydrocarbons (hydrogen and carbon compounds) just like South Africa does with its natural gas and coal or Canada makes from water and oil tar sands.
