In a recent column, Williams sets straight the story on government ethanol mandates. For example, Williams notes:
Ethanol is 20 to 30 percent less efficient than gasoline, making it more expensive per highway mile. It takes 450 pounds of corn to produce the ethanol to fill one SUV tank. That's enough corn to feed one person for a year. Plus, it takes more than one gallon of fossil fuel -- oil and natural gas -- to produce one gallon of ethanol. After all, corn must be grown, fertilized, harvested and trucked to ethanol producers -- all of which are fuel-using activities. And, it takes 1,700 gallons of water to produce one gallon of ethanol. On top of all this, if our total annual corn output were put to ethanol production, it would reduce gasoline consumption by 10 or 12 percent.
Ethanol is so costly that it wouldn't make it in a free market. That's why Congress has enacted major ethanol subsidies, about $1.05 to $1.38 a gallon, which is no less than a tax on consumers. In fact, there's a double tax -- one in the form of ethanol subsidies and another in the form of handouts to corn farmers to the tune of $9.5 billion in 2005 alone. There's something else wrong with this picture…
The ethanol hoax is a good example of a problem economists refer to as narrow, well-defined benefits versus widely dispersed costs. It pays the ethanol lobby to organize and collect money to grease the palms of politicians willing to do their bidding because there's a large benefit for them -- higher wages and profits. The millions of gasoline consumers, who fund the benefits through higher fuel and food prices, as well as taxes, are relatively uninformed and have little clout.
Once again, Williams makes it clear, and is right on the mark.
