Power hungry computers not as hungry as expected

After all the complaining about the power used by the nation's computers, the San Francisco Chronicle is reporting that a study(admittedly commissioned by a computer chip manufacturer, AMD) indicates that the use is close to 1.2%. Not small, but nowhere near the 13% touted by some sources. It is true that computers are using more power per square foot than originally expected in many data centers, but apparently it's not the leading cause of global warming that it's been made out to be by some.
