Ethanol has a few knocks of its own

For one, the biofuel won’t replace oil.

As drivers cringe at the cost of filling up this summer, the ethanol industry is spending billions to build on the biofuel’s momentum as an alternative to gasoline.

Advocates trumpet ethanol as a homegrown fuel that builds rural economies, benefits the environment, and enhances national security.

General Motors Corp. is promoting its line of “corn-fed” flex-fuel vehicles with a “Live Green, Go Yellow” advertising campaign.

So as ethanol works its way into the U.S. fuel market, is “fill up, feel good” – as one ethanol promotion group urges – the proper attitude for American drivers?
