Miami, there may be some misperception, possibly on your part here. The purpose of ethanol is NOT to reduce emissions. The purpose of ethanol is to, supposedly and originally, to decrease the dependence on foreign oil. It was to reduce 10% of oil imported. However, it fails. The creation of ethanol uses more energy than it saves. As an example, the seed producer ships the seed to distributors by truck using fuel, the farmer drives trucks to the distributor to pick up the seeds, again using fuel, the farmer plants the seeds using a tractor using fuel, the farmer harvests the crop using a tractor or combine using fuel, the farmer transports the corn to an ethanol processing plant using fuel to deliver, the processing plant uses electricity and fuel (gas) to process the corn, and cook the corn batch to convert to alcohol, then it is placed in trucks to be shipped to refineries where it is added to gas. It has already taken more energy to produce than it saves. Then ethanol has fewer BTU's than gasoline so it gets fewer miles per gallon, which means you have to use more fuel to travel the same distance, creating even more pollution. BTW- more pollution is created to produced the electricity at the processing plant and for the electricity or gas or liquified gas to cook that ethanol batch all of which produce pollution. So ethanol has nothing to do with fewer emissions. It is just a program to support the farmers. Now that the farmers use more corn for ethanol there is less for live stock feeding, which converts to simple economics 101, supply and demand, so it costs more to feed horses, pigs, cows, etc, which raises the cost of everything we eat. Again, ethanol is not about pollution.
I also want clean air and water. But the EPA has proven to be tyrannical and dictatorial and sadly lacking in common sense in many areas choosing to protect certain species to the detriment of humans and their families. IMO, they are out of control.
