"One often overlooked but nonetheless crucial aspect of the Navy's effort to become more sustainable is the culture change that it's driving in the rank and file. The Navy has created programs to train its sailors and Marines to be more aware of the importance of energy savings, the dangers posed by being dependent on foreign oil, and the need to preserve natural resources such as water. Says Mabus: "We've got SEAL teams now that are trying to be net zero in terms of both fuel and water." Every year 100,000 or so clean-cut young men and women leave the military and return home with a new perspective on how the world should work. Many will become leaders in their communities who, in the long run, might very well help change the way we live. In the end, that might be the Great Green Fleet's lasting legacy."This is a sea change from the "We need an energy bill that encourages consumption" era.Hooah!
