Even though bioethanol is an outstanding renewable engine fuel, it is more suited to Otto gasoline (petrol) than to farm diesel engines. Electricity may be generated from a range of renewable sources including wind, wave, hydro and biomass, but on-farm generation is unlikely except on a small-scale or on the basis of specialized energy or wind-power farms.Thus, huge savings in labor have accrued from engine-driven mechanization systems in the developed world, which in turn have been rapidly followed by rural depopulation. The societal impact of rural depopulation has not been adequately addressed.
