"Domestic crude oil production in the United States has increased over the past few years, reversing a decline that began in 1986. The United States is now a net exporter of refined petroleum products. Over the next 10 years, continued development of unconventional oil resources, in combination with the ongoing development of offshore resources in the Gulf of Mexico may push domestic crude oil production to a level not seen since 1994, according to the U.S. Energy Information Administration. An important policy question for Congress may be whether a domestic biofuel industry is necessary for national defense, and whether proceeding under the authority of the DPA [Defense Production Act of 1950] offers the necessary stimulus. A domestic biofuel industry may satisfy concerns for a secure, domestic, alternative fuel source independent of unstable foreign petroleum suppliers. However, adding biofuel to the military's supply chain does not relieve logistical issues with delivering fuel to forward operating areas, where fuel supply issues have been more about vulnerability than availability."
