For years, some experts have predicted that the depletion of global oil reserves—and the resulting rising price of oil—would make U.S. dependence on foreign oil economically untenable. Calls to address American energy consumption are nothing new. Yet technology has expanded the industry’s ability to find and extract oil: The National Petroleum Council estimates the total proven reserves at 1.2 trillion barrels—38 years of supply at current rates of consumption. It is likely that another trillion barrels of undiscovered oil exist, as well as 1.5 trillion barrels of “unconventional” reserves of heavy oil, according to the federally chartered advisory committee. As Vijay Vaitheeswaran argues in Foreign Policy magazine, “the world is simply not running out of oil. It is running into it.”

Recently, then, many advocates of oil independence have shifted from an economic argument, which has become hard to sustain at a time when governments are paying $98 a barrel for oil, to a security argument—although this is not to say that national security was not a concern at all previously. Besides the failure of alarmist predictions, two factors explain the shift from an economic to a security discourse: climate change and terrorism. The growing awareness of the causes and extent of climate change has tarnished the image of fossil fuels. According to a BBC poll, 50 percent of the world population favors higher taxes on fossil fuels.

Even more than climate change, however, it is the links between oil and terrorism that cause concern among policymakers. At a conference at the Brookings Institution, former CIA director James Woolsey argued that oil revenue often flows to Islamist regimes that finance madrassas, which educate the next generation of terrorists. Oil can be a source terrorism, but it can also be a target. Oil convoys are one of the main concerns of U.S. troops in Iraq, as they are frequently attacked by terrorists. In addition, the oil fields of the Niger Delta are often attacked by rebel groups.

In his book Freedom from Oil, David Sandalow, an expert on energy policy and climate change, explores what could happen if the next president prioritized oil independence– which he defines as reducing U.S. oil consumption to the point that imports are minimal. [For Sandalow’s response, read comments below.] He believes the transportation complex should be the target of future policies, and that biofuels and plug-in cars are part of the solution. Indeed, as Vaitheeswaran notes, “this year, two-thirds of U.S. oil consumption—and half of global oil consumption—will be sucked up by cars and trucks. Reinventing the car is the only serious way to wean the world off oil.”

“Energy is a critical, yet hugely neglected, determinant of human health. Health is an important enough aspect of energy policy to deserve a much greater influence on decisions about our future personal, national, and global energy strategies….Energy is as important as any vaccine or medicine. 2 billion people currently lack access to clean energy: they live in energy poverty and insecurity. International institutions, such as the World Bank and WHO, have repeatedly failed to make the connection between energy and health in their country work,” writes Lancet editor Richard Horton in the journal’s September 15, 2007 issue.

A six-article series in The Lancet examines how energy use—or the lack thereof—affects human health. Providing needed data on the health and economic impacts of both energy use and energy scarcity, the series explores one of the many links between environment and human security.

As Americans grow increasingly uneasy with our reliance on oil imports from the Middle East, a new region in Africa—the Gulf of Guinea—is emerging as a pivotal oil exporter. An ambitious new book, Oil and Terrorism in the New Gulf, written by James J. F. Forest and Matthew V. Sousa, focuses on this region of Africa and highlights the U.S. strategic interest in its oil-producing countries: Angola, Cameroon, Chad, Congo, Equatorial Guinea, Gabon, Nigeria, and the island nations of Príncipe and São Tomé. This “New Gulf” not only provides the U.S. with a new oil supply, but also affords a chance to reframe our energy relationships.

To an American “outsider” like me, a recent conference in Berlin on integrating environment, development, and conflict prevention reflected the stark contrast between our policies and those of the EU. Though we are confronting similar situations – indeed, the same situation – we are dealing with them quite differently. In recent years, European policymakers have tried to balance environmental and energy concerns, working to decrease humans’ impact on climate and the environment and encourage environmental cooperation, while still generating enough energy for growth.

Academics and policymakers alike appreciate the complexity of new threats to national security like non-state actors and global terror networks. But a report released in September 2006 by the Princeton Project on National Security (PPNS) warns that ignoring unfashionable, but long-established geopolitical threats can endanger U.S. foreign policy. Billed as a bipartisan initiative, PPNS is ultimately an academic affair, with members of its group including such luminaries as Francis Fukuyama, G. John Ikenberry, Laurie Garrett, Thomas Homer-Dixon, Tod Lindberg, and Walter Russell Mead, among many others. The initiative engaged these experts to develop a basic framework of principle threats to U.S. national security and potential responses.
