The Carbon Calculus

By Matthew L. Wald, Published New York Times: November 7, 2007

"A CHANGE is in the works that could go a long way toward making alternative energy less alternative, and more attractive to consumers and businesses.

It’s not a technological fix from some solar-cell laboratory in Silicon Valley or wind-turbine researcher in Colorado or the development of some superbug to turn wood waste into ethanol.

Rather, the change would come from Washington, if Congress does what it has talked about and puts a price tag on greenhouse-gas emissions. Suddenly the carbon content of fuel, or how much carbon dioxide is produced per unit of energy, would be as important as what the fuel costs. In fact, it might largely define what the fuel cost." MORE
