IB DP ESS — Topic 7: Natural Resources (HL Extension) | HL | Paper 1 & Paper 2A/2B
🎯 Learning Intentions By the end of this note, you will be able to:
- Define energy security and explain why it is a central concern for both environmental systems and human societies.
- Explain the formation, extraction, and combustion of fossil fuels, and analyse the environmental consequences at local, regional, and global scales.
- Describe the concept of peak oil and its implications for energy transitions and geopolitical stability.
- Analyse the full lifecycle environmental impacts of nuclear power, including uranium mining, reactor operation, and radioactive waste management.
- Evaluate the role of battery storage technologies in enabling the transition to renewable energy systems, considering trade-offs in resource use, sustainability, and equity.
- Discuss contrasting worldviews — ecocentric, technocentric, and anthropocentric — in relation to energy choices and the concept of energy security.
- Compare and contrast fossil fuels, nuclear power, and battery storage as energy solutions using ESS analysis parameters: scale, sustainability, trade-offs, and multiple perspectives.
Real-World Context & Relevance
In February 2022, Russia's invasion of Ukraine triggered the most severe energy crisis Europe had experienced in decades. Germany, which had sourced approximately 55% of its natural gas from Russia, was forced to make an emergency pivot — reactivating mothballed coal plants, accelerating offshore wind contracts, and importing liquefied natural gas (LNG) from the United States and Qatar at record prices. Household energy bills across the European Union rose by an average of 41% in 2022, and energy poverty — the inability to afford adequate heating or cooling — affected an estimated 41 million EU citizens (International Energy Agency, "World Energy Outlook 2022"). This crisis did not emerge from a sudden shortage of fossil fuels in the ground; it emerged from a failure of energy security: the vulnerability of a society's energy supply to disruption, price volatility, and geopolitical pressure.
The European energy crisis illustrates a tension that sits at the heart of this topic. Fossil fuels — coal, oil, and natural gas — have powered industrial civilisation for over 150 years and remain the source of approximately 80% of global primary energy consumption. Yet their combustion is the dominant driver of anthropogenic climate change, their extraction degrades ecosystems, and their geopolitical concentration creates systemic fragility. Nuclear power offers a low-carbon alternative but generates radioactive waste that persists for tens of thousands of years. Battery storage technologies promise to unlock the full potential of intermittent renewables, but depend on lithium, cobalt, and rare earth elements whose mining carries its own environmental and social costs. Understanding these trade-offs — not just the technologies themselves — is the central analytical challenge of this topic.
🌍 Why This Matters Energy choices are among the most consequential decisions human societies make. They determine greenhouse gas emissions trajectories, ecosystem integrity, geopolitical relationships, and the distribution of environmental burdens between wealthy and poor nations. The transition away from fossil fuels is not simply a technical problem — it is a systems challenge involving feedback loops between energy infrastructure, economic systems, political institutions, and ecological limits.
Core Concepts & Definitions
Before examining individual energy sources, it is essential to establish what we mean when we say a country's energy supply is "secure." Think about what makes any supply chain vulnerable: dependence on a single supplier, price volatility, physical infrastructure that can be disrupted, or a resource that is finite and depleting. Energy security captures all of these vulnerabilities simultaneously, and addressing it requires understanding both the physical properties of energy sources and the social, economic, and political systems through which they are accessed and distributed.
📖 Key Definition — Energy Security Energy security is the uninterrupted availability of energy sources at an
