Biofuels - for the temperate climate, alcohol derived from Jerusalem artichokes or waste orchard fruit appears to be the proven, sustainable route of fueling cities. Crop productivity and fuel usage calculations indicate that most cities, worldwide, scale in size in such a fashion that they can produce all their vehicle fuel needs from a land area equivalent to the size of the city - as long as this calculation is not based on the inefficient, though touted, alcohol from corn - but on perennial crops such as Jerusalem artichokes. This would not contribute to the food-or-fuel scenario that detractors of this proposition point out. Key: this is proven technology, and vehicles can run on alcohol with minor modifications. In the tropics, palm oil appears to be the solution for fuel needs, based on yields.
