The Los Angeles Times breaks bad on ethanol.

To the annals of market manias and regulatory follies, a new chapter is being added: The Great Ethanol Bubble of 2008. It is possible that someday a fuel made from a cheap, abundant, renewable crop may replace oil. But it won't be food-based ethanol. It's time not only to stop subsidizing the stuff but to revamp the chaotic, politicized and wasteful system of subsidies for alternative energy.

It is now well established that inefficient corn ethanol actually pumps out more total life-cycle carbon emissions than gasoline, and total emissions from ethanol coming even from the most advanced refineries offer at most a 25% improvement over gasoline in terms of greenhouse gases -- at a staggering environmental and financial cost.
