Sen. Ben Cardin and Karen Hostler are right in saying we do not need ethanol as a gasoline additive, while Stephanie Dreyer is a spin artist in her response to their comments ("Ethanol makes sense," Sept. 1). While not entirely inaccurate, the omissions in her arguments are significant.
For example, Ms. Dreyer expertly avoids mentioning that ethanol is produced by burning carbon fuels and that studies have shown only marginal energy savings in ethanol use over gasoline. Ethanol also results in lower gas mileage compared to traditional gasoline.
By treating the increased cost of corn and the higher cost of feed grain as insignificant, Ms. Dreyer appears oblivious of the true cost of ethanol as a fuel.
