"Robin Eckstein deployed to Iraq as an Army truck driver shortly after the U.S. invasion in 2003. Her job: hauling supplies to U.S. bases from the Baghdad airport. ...
One of the primary cargoes for those convoys was petroleum - fuel for the massive machinery of war.
Eckstein began wondering: Why couldn't the vehicles be more fuel-efficient? Why not use solar generators? Why not insulate the troops' tents?
Eckstein came home determined to help make the case to her fellow Americans that energy efficiency isn't some pie-in-the-sky issue. It's a matter of dollars and cents - and literally a matter of life and death for U.S. troops in harm's way."
