emissions for the light transportation sector can you identify that will produce more GHG emissions reductions than ethanol is currently... oh, well that's already known. There is no technology that is producing anything close to Ethanol's current GHG reductions. Then, perhaps you have a technology you would identify for its future potential? Since you have "accomplished detailed academic study" this should not be a problem. Your use the terminology "academic study". Is that meant to imply this is a formal study completed to meet some academic requirement (a book report perhaps)? ... or are you employing a little 'poetic license' just for our benefit.
But more than that, since ethanol does produce GHG emissions reductions now, what is your argument for not employing this technology. Why would we give up the GHG reductions we currently are achieving with ethanol - since, Global Warming is proceeding as we speak and accelerating.
I do not exclude any technology that gets results as you are doing with ethanol. We will need all the techniques and technologies available to us - including biofuels and hybrid vehicle technologies (incl PHEVs) - to achieve the maximum reductions to GHG emissions for the light transportation sector. It will take two or three decades to achieve significant GHG reductons with hybrids (and PHEVs). Why would we forego the GHG reductions ethanol can achieve over the ensuing 20 to 30 years?
Again, if you claim I misused data, please identify such misuses.
