Navy Secretary Ray Mabus believes that the U.S. military can jump-start the clean energy revolution. Upon assumption of office and throughout his tenure, Mabus has prioritized decreasing the department’s dependence on fossil fuels. His ambitious plan to slash fuel use and carbon emissions means that by 2020 half of the energy consumed by the Navy and the Marine Corps will come from alternative sources, including nuclear energy and biofuels. Mabus’ history of leadership includes serving as Governor of Mississippi and Ambassador to Saudi Arabia.
