The document discusses the benefits of expanding alternative fuel use in the United States. It notes that the US spends $700 billion annually importing oil, including 38% from unstable regions, and could reduce imports by 40% through expanded wind, solar and domestic fuels like natural gas. This 40% reduction could pay off stimulus funds in 4 years and cover almost half of annual social security expenses. More than 4,400 US military personnel have been killed in the Middle East during fuel resupply convoys. The document then provides examples of fleet fuel savings from converting vehicles to ethanol and compressed natural gas.
