Concerns about the United States' dependence on oil are nothing new, and various policy solutions have been around for decades. A number of scholars and experts have been attempting to address the subject, and one recent paper from The Brookings Institution offers a number of thoughtful ideas on this important concern. Released in January 2007, this 25-page paper written by David B. Sandalow offers a number of ambitious proposals aimed at reducing oil dependency in the US. Some of his proposals will sound familiar, as he includes references to the inherent possibilities in widespread adoption of biofuels, the adoption of smart growth policies, and the potential benefits of plug-in hybrid engines. Sandalow also offers some more specific details on how the auto fleet might be transformed over time, and also how the fuel supply might be transformed as well. It's a thoughtful work, and one that will be of interest to policy analysts and others who are concerned with this vexing issue.
