Stephen Walt argues for a return to a realism-based U.S. grand strategy.

For decades, fears of energy scarcity drove American energy diplomacy. The dependence of the global economy on oil, and America’s need to secure ever-growing quantities of this commodity, underpinned complex networks of alliances and intensive diplomatic endeavors. An atmosphere of ever-increasing global competition for resources made these labors all the more urgent and highstakes. Today, in an age of energy abundance, many anticipate that the new US energy prowess will render such efforts obsolete and pave the way for US disengagement in the world. Yet a sober look at reality suggests that this should be far from the case.

This study investigates whether, as part of a broader “Asian Energy Pivot,” Russia’s energy giant Gazprom refashioned its export strategy away from Europe, and what impact such a reorientation might have on the EU–Russia gas relationship. It uses four empirical cases to emphasize the domestic movers underlying Russia’s eastward shift in energy trade, developing a constructivist theory rooted in the dynamics of Russia’s dominant public narrative and the contours of domestic politics. It argues that Russia’s national interests changed as a result of how Russian policy-makers interpreted and reacted to the stand-off with Europe, in response to what they perceived as Europe’s attempt to isolate it economically and geopolitically. 

Many economists have long held that carbon pricing—either through a carbon tax or cap-and-trade—is the most cost-effective way to decarbonize energy systems, along with subsidies for basic research and development. Meanwhile, green innovation and industrial policies aimed at fostering low-carbon energy technologies have proliferated widely. Most of these predate direct carbon pricing. Low-carbon leaders such as California and the European Union (EU) have followed a distinct policy sequence that helps overcome some of the political challenges facing low-carbon policy by building economic interest groups in support of decarbonization and reducing the cost of technologies required for emissions reductions. However, while politically effective, this policy pathway faces significant challenges to environmental and cost effectiveness.

The world's energy system needs rebuilding. The Paris agreement to keep global warming “well below 2 °C above pre-industrial levels” demands that we replace fossil fuels with solar, wind, geothermal and biomass energy. The price tag is vast: investing US$120 trillion in energy projects between 2016 and 2050, at twice the current annual rate of $1.8 trillion a year, will deliver a 66% chance of achieving the Paris target. We must halve oil production and stop using coal to produce electricity.

The German energy transition—or Energiewende—stands out globally as one of the most prominent and widely discussed plans to transform an energy system. However, the ways in which Germany can and does promote the diffusion of its model remain to be systematically reviewed. Aiming at closing this gap, this article develops an analytical framework for "leadership by diffusion" and applies it to the Energiewende.
