Oil
Every facet of our lives are controlled and driven by oil. Energy has become the single most important factor for international politics. In this background, it was quite interesting to read in NYtimes about the brazil and sugarcane. One third of the all the energy requirements is met by locally grown sugarcane. Half the vehicles in brazil can run in a combination of oil and ethanol. Why dont we think about this? Do we have some implementation problems or is it the age old red tapism?
