This paper offers a framework the Gulf Coast (which disrupted oil and gas for assessing energy security based on an production and distribution, as well as the grappling with the evaluation of vulnerability, risk, and offsets; electrical grid), and high winds in California security implications this approach has been a useful tool for that caused widespread power outages of an energy system in assessing oil security for the past 50 years, have brought energy security once again transition—and if they into the global headlines. and it can be relevant for assessing energy aren't, they should be. security in an energy system in transition. Even with the US now on a trajectory to achieve the long-sought goal of energy self- sufficiency, global energy security remains INTRODUCTION a strategic and economic challenge. While self-sufficiency would alleviate some of the Energy security considerations are not traditional concerns about global supply new phenomena.

In this paper, reduce demand by conserving energy. I argue that this framework can be useful for The purpose of these interventions is to assessing the security of an energy system cushion the impact of the shock while giving in transition—in particular, a transition away markets—both producers and consumers—a from coal and oil toward natural gas and chance to respond in a more orderly fashion. renewables in part due to climate change. Energy security policy can aim to I will apply this framework of vulnerability, address any of these dimensions. For risk, and offsets to the current oil market and example, vulnerability can be reduced a potential future energy system in transition by diversifying the fuel mix, risk can be to renewable energy and natural gas. This managed via diplomacy or military power, discussion is not intended to be an exhaustive and a strategic stockpile can be used to review of all potential facets of the issue, offset lost supply. but as an illustration of the framework’s application. I primarily focus on the US, but with some consideration of other key energy APPLYING THE FRAMEWORK TO OIL players and the world as a whole. Vulnerability Global—and US—vulnerability to oil shocks THE FRAMEWORK has improved significantly in recent years, but it still remains a significant concern. The The first element of the framework is shale revolution has put the longstanding vulnerability, which is how exposed the US goal of energy self-sufficiency within US and global energy systems are to a reach. The US recorded the world’s largest shock. This could include the size of the ever increases in production of both oil and energy input to the economy (in absolute natural gas in 2018, and it is the world’s terms and especially in financial value), largest producer of both fuels. In addition, the degree of substitutability, and the the country is now a net exporter of natural concentration in key sectors, such as the gas and has seen net oil imports as a share importance of oil in transport.
