The Great White Fleet, dispatched by President Theodore Roosevelt in 1907 and a milestone in U.S. Navy history, is today becoming the Great Green Fleet. Admiral Dennis McGinn, the Navy’s assistant secretary for energy, installations and environment as well as a retired rear admiral and former commander of the Third Fleet, sits down in his Pentagon office with host Bill Loveless to discuss the Navy’s commitment to sustainable and green energy in order to cut the service’s energy costs, reduce its emissions and make its fuel supplies more secure.
