Three core principles guide this curriculum and establish its analytical boundaries:
Material Foundations: Physical geography, resource endowments, and infrastructural configurations fundamentally shape state strategies, institutional arrangements, and systemic vulnerabilities.
Analytical Pluralism: No single theoretical framework fully captures the complexity of global energy politics; each perspective reveals specific structural or commercial dynamics while obscuring alternative explanations.
Epistemological Reflexivity: Energy security analysis is inevitably embedded within distinct historical, geographical, and strategic contexts, reflecting the material anxieties and normative assumptions of its origin.
Energy is one of the organising principles of international order, a source of state power and state vulnerability, a driver of conflict and cooperation, and an increasingly contested terrain of geopolitical rivalry. This course examines the relationship between energy systems and world politics through the sustained study of two strategic regions — Eurasia and Africa — while situating regional developments within the transformations reshaping the global order: the accelerating energy transition, the rise of critical minerals, the fragmentation of supply chains, and the strategic competition between established and emerging powers.
Energy outcomes are inherently multi-causal. Analytical evaluation must assess not only who benefits from specific infrastructural and market arrangements, but also what a given explanation overlooks, and from whose perspective an issue is framed. This course trains students to investigate energy as an instrument of statecraft and global governance while maintaining a critical awareness of the assumptions underpinning producer and consumer narratives, Global North and Global South perspectives, and hydrocarbon-era versus transition-era strategic logics.

Workshop: Application of concepts to real-world empirical cases.
Analytical Lab: Hands-on methodological training and data analysis.
Reflexive Question: A direct challenge designed to unpack hidden systemic assumptions.
Deep Thinking
What energy event, decision, or disruption occurred, and what are the verifiable facts about the resources, infrastructure, market structures, and physical geography involved? (Empirical baseline)
Which state, corporate, or institutional actor controlled the decision, and what was their structural position in the energy value chain (producer, consumer, transit jurisdiction, or financial intermediary) and how did that position shape their available choices? (Agential mapping)
Which theoretical framework (realist resource mercantilism, geoeconomics, liberal institutionalism, critical political economy, or postcolonial critique of extraction and dependency) best explains the energy dynamic at issue, and what assumptions does it make about markets, geography, and power? (Theoretical application)
What does this explanation fail to account for — whose energy interests are rendered invisible, which transition dynamics are suppressed, or what alternative conceptions of energy security are excluded from the dominant framing? (Analytical limitation)
How does this event look from the perspective of a producing state, a transit jurisdiction, or a resource-dependent Global South economy and what does that perspective reveal about whose understanding of energy security has been treated as universal? (Reflexive critique)
Apply multi-causal, multi-theoretical analysis to energy politics: Examine energy security disputes by integrating geographical, technological, macroeconomic, and political-institutional variables, and evaluate competing frameworks (realist resource mercantilism, geoeconomics, liberal institutionalism, and postcolonial critique of extraction) while clearly articulating the explanatory strengths and limits of each.
Deconstruct primary sources and deploy geoeconomic methodological instruments: Critically evaluate national energy strategies, infrastructure concessions, transit treaties, and corporate disclosures to identify misalignments between rhetorical frameworks and material allocations, and apply supply-chain dependency mapping, maritime chokepoint exposure analysis, and resource-rent tracing to specific empirical cases.
Practise epistemological reflexivity across producer, consumer, and transition perspectives: Situate contemporary energy discourses within their historical and political contexts, identify the systemic biases embedded in both fossil-fuel security narratives and green transition models, and assess how energy security is defined differently by producing states, consuming states, transit jurisdictions, and resource-dependent Global South economies.
Produce professional-grade energy risk and strategic foresight assessments: Formulate rigorous, evidence-based policy briefs and scenario-based risk reports that satisfy the five-rule analytical framework and reflect the standards of analysis expected in strategic consultancy and intelligence contexts.
Assessment 1: Energy Strategy and Infrastructure Analysis (35% | 2,500 words)
Students select one primary document or case (a national energy strategy, an infrastructure concession agreement, a pipeline treaty, a maritime boundary claim related to resource access, or a corporate energy disclosure) and subject it to a sustained analytical critique structured around the five-rule framework. The analysis must establish the material facts of the case and identify the producing, consuming, transit, or corporate actors involved and their structural position in the energy value chain; deploy at least two competing theoretical frameworks drawn from realist resource mercantilism, geoeconomics, liberal institutionalism, or postcolonial critique of extraction; and apply one methodological instrument from the Analytical Labs, such as supply-chain dependency mapping, chokepoint exposure analysis, or resource-rent tracing, to support the empirical argument. The analysis must conclude by identifying whose conception of energy security is privileged by the dominant framing and whose interests are structurally excluded from it. Submission Deadline: End of Week 7.
Assessment 2: Capstone Energy Risk and Foresight Report (55% | 5,000–6,000 words)
The primary summative assessment for this course is a comprehensive geopolitical risk and strategic foresight report focused on an active contemporary energy challenge or infrastructure flashpoint selected from the approved case list. The report must map the multi-causal drivers of the case across geographic, resource-based, technological, and political-institutional dimensions; construct a data-driven account of the key state and corporate actors and their competing strategic interests; and develop three internally coherent and mutually exclusive scenarios for the global or regional energy order over a 20-year horizon. The analysis must deploy at least two theoretical frameworks explicitly, apply two methodological instruments introduced in the Analytical Labs, and include a dedicated section critiquing Western-centric or fossil-fuel-era assumptions about the case through Global IR or decolonial frameworks. All five rules of the analytical framework must be visible throughout. Submission Deadline: Sunday of Week 14 (Formal Assessment Period, following the conclusion of Week 12 teaching).
Assessment 3: Seminar Participation and Analytical Engagement (10% | Ongoing)
Participation is assessed continuously throughout the semester. Marks reflect the quality and consistency of engagement across three interconnected dimensions: contribution to seminar and workshop discussions, demonstrating the ability to apply theoretical concepts to empirical cases and to challenge competing interpretations with reasoned argument; performance in the weekly Analytical Labs, showing growing proficiency in applying course methodologies to live data and case material; and conduct in simulation and debate exercises, including the willingness to defend positions under adversarial questioning, respond to new evidence, and revise conclusions accordingly. Attendance is a prerequisite for participation credit, but marks are awarded for the quality and intellectual rigour of engagement rather than for the volume of contribution.
All written work must be submitted as a PDF file, regardless of the word processor used.
Use font at 12 points Aptos or Arial. Pages must be numbered. Include your name, student number, course name, assignment title, and word count on the first page; a separate cover page is not required.
The word count stated in the assignment brief is a guide to scope and depth, not a rigid threshold. Work within 10% of the stated count in either direction. The word count covers the main body of the text, including in-text citations, but excludes the reference list, any tables or figures, and any appendices.
All written work must follow APA 7th edition throughout. In-text citations use the author-date format: (Yergin, 2020) or Yergin (2020) argues that… For direct quotations, include the page number: (Yergin, 2020, p. 47). The reference list appears at the end of the document, ordered alphabetically by surname. Do not use footnotes for references; footnotes may be used sparingly for substantive clarifications that would otherwise interrupt the argument.
Formal policies on academic integrity and the use of AI tools vary by institution and will be communicated where applicable. The question beneath those policies does not change: Is the goal to understand, or simply to appear to have understood? A qualification obtained without the knowledge it is meant to represent is a transaction, not an education, and it shortchanges the holder as much as anyone else. I invest genuine effort in connecting students to scholarship, practitioners, and professional networks that extend well beyond any syllabus. Whether that investment meets a reciprocal commitment is, in the end, a question of character rather than compliance.

Research articles do not appear in the bibliography above. This is intentional. Each week, students are expected to identify a peer-reviewed article relevant to that week’s topic, bring it to the seminar, and share it with the group. The lecturer contributes selections alongside the class. This practice develops independent literature-searching habits, exposes the seminar to a wider range of scholarly perspectives than any fixed reading list could provide, and keeps the course in sustained contact with current debates in the field.
