If Ernie Shea is right and ethanol is still the answer, he is wrong if he believes that corn-based ethanol is the right answer ("Ethanol still the answer," Sept. 21). I have no problem with the Renewable Fuel Standard passed by Congress. I do have a problem with producing ethanol from corn.
Sugar cane is a better source, but our tariffs on sugar and our embargo on Cuban products keep us from making ethanol for less. There may be other better sources than corn. By the way, my gas may be less expensive with ethanol, but I also get fewer miles per gallon. I wonder whether the one outweighs the other.
