The subtitle tells the story. In the early 2000s, many pundits and politicians talked up “peak oil”, “energy scarcity,” and all that. In a geological heartbeat later—about a decade—the world had entered an era of “energy abundance,” largely due to innovations that allowed producers to crack into shale formations to release massive new sources of oil and gas. The United States has gone furthest and fastest in fracking and is setting records for oil and gas production. For the US, says O’Sullivan, this has been an economic, strategic, and environmental game-changer. For the rest of the world, the effects are more differentiated but hardly less profound.

To address emissions, the electric grid would need to eliminate fossil fuels and the petrochemical industry would need to reverse its explosive growth.

In conclusion, much has been written about the world's energy resources, but only a few books have been able to link energy realities to geopolitics. Windfall provides an important corrective to conventional wisdom on foreign and energy policies—and shows how the US can take full advantage of the new energy landscape. Thus O'Sullivan shows that by looking at both foreign policy and energy markets, businesses will make better investment decisions and policy-makers will make better strategic decisions.

During our holiday newsletter hiatus, I finally had time to read Meghan O'Sullivan's book (pictured above) about how the shale boom is shaking up global oil-and-gas markets — a phenomenon that has broad and important geopolitical effects.

The boom benefits U.S. global posture and economy, but O'Sullivan warns that policymakers cannot be complacent and must take steps to harness its geo-strategic benefits while mitigating environmental risks.
