Contemporary biofuels made from sugars, starches and plant oils are incorporated into gasoline and diesel supply systems. Is this the best use of potential food resources, or should we look to other feedstocks? Is it desirable to use wood? What biomass is available? Is its use sustainable? What are current domestic policies and are they working? Why are we concerned about biofuels anyway? What about electrical vehicles? How much can be gained from efficiency? Which conversion technologies work? How much do they cost? These questions have been researched through large government-sponsored programs and actively debated for at least the past 35 years. Conceptually, the approach is even older.<br>
If we are serious about environmental sustainability, feeding our population and renewing a hope for future society, we must think realistically about feasible alternatives to present practices.
