The document discusses how the United States' oil consumption negatively impacts national security and the environment. It argues that oil empowers America's enemies, climate change acts as a threat multiplier by disrupting food, water, health and shelter, and that impacts are seen around the Strait of Hormuz and in operations in Afghanistan where fuel convoys put lives at risk. It provides examples of the USS Makin Island and F/A-18 Hornet that use more efficient energy sources and argues that developing local industries in renewable energy and efficient technologies can create jobs and address these issues.
