For Security, Get Off Oil; September 2008; Scientific American Earth 3.0; by Stephen D. Solomon; 4 Page(s)

At R. James Woolsey¿s farm in southern Maryland, solar panels on the roof of his house send electricity back to the utility grid when his family is not using much power. And he drives a Toyota Prius hybrid with a conversion kit that enables him to recharge the car¿s battery pack using an extension cord and household current.

Woolsey isn¿t the average citizen who has gone green. As the former director of the Central Intelligence Agency from 1993 to 1995, Woolsey warns that the U.S. faces a grave national security threat from its dependence on energy derived from oil. ¿I think we need to go right for oil¿s jugular vein,¿ he says.
