Ethanol isn't enough, but ethanol hybrids could be just right

Over the last several months there has been a tremendous amount of hype around ethanol. In fact, GM's GoYellow campaign seems to imply that every American could drive a flex-fuel Hummer and America could still end foreign oil dependency. Yet, scientists don't agree, and they say corn-based ethanol will have little effect on foreign oil consumption.

Of course, ethanol supporters suggest other forms of biomass, such as cellulosic ethanol - which still requires undeveloped technologies - could possibly achieve a 30% drop in gasoline consumption by 2030. "There are many people who believe that biomass has the power to replace our appetite for gasoline," said Kimberly Gray, professor of civil and environmental engineering at Northwestern University. "But that will only occur with significant improvements in energy efficiency and smart growth." (more)

In reality, despite GM's marketing deception, corn offers very little hope for America's fuel needs, especially if GM only produces Tahoes and Hummers. America needs smaller vehicles, and it needs millions and millions of hybrid cars. While smaller flex-fuel hybrid cars won't end gasoline consumption anytime soon, they could end foreign oil dependency - something flex-fuel gas guzzlers will NEVER accomplish.
