There are so many reasons ethanol shouldn't be priority #1 in America's quest for petroleum replacement. I blogged about this previously here.
Yet another reason to think again about the ethanol craze in an article in today's LA Times.
Of our "alternative fuel" options, only electricity can truly be made renewably (wind, solar, geothermal, small hydro), with no carbon or other noxious emissions. And only electric drive cars can operate truly zero-emission. We need to prioritize clean electricity generation and plug-in battery cars to utilize that energy efficiently.
