## Introduction

In Unit 9, petroleum and nuclear energy are strong examples of both **change** and **continuity** in the modern world. The big change was that energy became more global, more political, and more technologically advanced than ever before. Oil powered cars, ships, aircraft, factories, and mechanized armies. Nuclear energy introduced a new source of electricity and a new level of scientific prestige.

At the same time, an older pattern continued. States still competed over resources, still tried to control strategic trade routes, and still used technology to strengthen their power. That makes this topic perfect for AP continuity and change over time questions: the energy system changed, but struggles over power, profit, and control did not disappear.

> **Key Term: continuity and change over time**
> A historical reasoning skill that explains what changed and what stayed the same across a period.

### Petroleum and the rise of global energy politics

Petroleum mattered because it fit the needs of the 20th century better than older fuels in many sectors. It was portable, easy to transport by tanker or pipeline, and useful for internal combustion engines. That made it crucial for automobiles, aviation, shipping, mechanized warfare, and later mass consumer life. A country with access to oil could power transport, industry, and armies more effectively.

That changed global geography. Regions with large oil reserves, especially the **Middle East**, became strategically vital to industrial economies. Outside powers had long interfered in resource-rich regions, but oil made that interference even more intense. This is where continuity appears: states were still competing over valuable resources, much as they had competed over spices, silver, or cotton in earlier periods. The resource changed; the struggle did not.

> **Key Term: petroleum**
> A fossil fuel, also called oil, used to power transport, industry, warfare, and petrochemical production.

Oil also shifted political power toward some non-Western states. At first, foreign corporations often dominated extraction through concessions. Local rulers received payments, but outside firms kept much of the control. Over time, many governments challenged this arrangement.

> **Key Term: resource nationalism**
> State efforts to assert control over natural resources, often by reducing foreign ownership or nationalizing companies.

A major example is **Iran in 1951**, when Prime Minister **Mohammad Mossadegh** nationalized the Anglo-Iranian Oil Company. This was not just an economic decision. It was a claim to sovereignty after years of foreign influence. Similarly, **Saudi Arabia** gradually gained control over Aramco in the 1970s and completed full nationalization in **1980**. These examples show a change in who controlled oil wealth, but also a continuity in the idea that states wanted strategic resources under their own authority.

### OPEC, the oil embargo, and producer power

One of the most testable developments is the creation of **OPEC** in **1960** by **Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela**. OPEC allowed producer states to coordinate production and pricing more effectively. This mattered because it challenged the earlier dominance of Western oil companies and consumer states.

> **Key Term: OPEC**
> Organization of the Petroleum Exporting Countries, founded in 1960 to coordinate oil production and pricing among member states.

Students often blur OPEC and OAPEC. They are linked, but not identical. **OAPEC**, founded in **1968**, was a group of Arab petroleum exporters. This distinction matters for the exam because the **1973–1974 oil embargo** was carried out by Arab producers, not by all of OPEC as a whole.

> **Key Term: OAPEC**
> Organization of Arab Petroleum Exporting Countries, important for leading the 1973–1974 oil embargo.

The embargo followed the **Yom Kippur War** of **1973**. Arab oil exporters cut shipments to the **United States** and other countries seen as supporting Israel. Oil prices surged. Industrial economies faced shortages, inflation, and political anxiety. This was a turning point because it showed that producer states in the Global South could pressure powerful industrial consumers.

This is a very useful AP argument. Before this, many students assume globalization only increased Western power. The oil crisis complicates that claim. It shows that globalization also gave power to non-Western states that controlled strategic resources.

> **Test Tip:** If a prompt asks how non-Western states gained influence after 1900, the 1973–1974 oil crisis is strong evidence. Explain not just that prices rose, but that producer states used control of supply as political power.

The embargo also encouraged new policies in importing states: energy conservation, search for alternative energy, and in some countries greater interest in nuclear power. That links petroleum directly to the next part of the topic.

### Nuclear energy: modernization, prestige, and dual-use technology

Nuclear energy grew out of 20th-century advances in atomic science. After World War II, countries developed civilian reactors to generate electricity. The first commercial nuclear stations appeared in the **1950s**. Governments promoted nuclear power as modern, scientific, and efficient. It promised large-scale electricity generation without direct burning of coal or oil.

> **Key Term: nuclear energy**
> Energy produced from nuclear reactions, especially used after World War II for electricity generation.

Nuclear energy is a classic **dual-use technology**. The same broad scientific field that produced civilian reactors also produced atomic weapons. That is why nuclear technology sits at the intersection of development and danger.

> **Key Term: dual-use technology**
> A technology with both civilian and military applications.

The military side is obvious: the atomic bombings of **Hiroshima** and **Nagasaki** in **1945** opened the nuclear age, and the Cold War arms race followed. But for this topic, the key is not to turn the whole answer into a weapons essay. The exam wants you to connect nuclear energy to modernization as well. States invested in civilian reactors to show technological sophistication, increase energy security, and reduce dependence on imported fuel.

Countries adopted nuclear power for different reasons. **France** expanded nuclear energy strongly after the 1970s oil shocks. **Japan**, with limited domestic fossil fuels, also relied heavily on nuclear power before 2011. **China**, **India**, and **South Korea** later expanded nuclear systems as their energy demand rose.

This shows a change in the energy mix: not just fossil fuels, but a new source of state-led electrification. Yet continuity remained because governments still saw control of strategic technology as a route to national power and prestige.

### Nuclear accidents and the limits of technological confidence

Nuclear power also showed the risks of modern energy systems. It produced less direct carbon pollution during operation than fossil fuels, but created problems of radioactive waste, high costs, and the possibility of catastrophic accidents.

**Three Mile Island** in the **United States** in **1979** increased public fear and encouraged anti-nuclear activism. But the two most important examples for AP World are **Chernobyl** and **Fukushima Daiichi**.

> **Key Term: Chernobyl disaster**
> The 1986 nuclear reactor accident in Soviet Ukraine that released major radioactive contamination.

**Chernobyl** happened on **26 April 1986** in **Soviet Ukraine**. It resulted from a flawed **RBMK reactor** design combined with serious operator and safety failures during a test. The reactor exploded and burned, releasing radioactive material far beyond the Soviet border. This matters historically for several reasons.

First, it exposed weaknesses in the Soviet system: secrecy, poor safety culture, and lack of accountability. Second, it showed that environmental damage from advanced technology could be **transnational**. Fallout did not stay local. Third, it damaged public trust in nuclear power across Europe and beyond.

> **Key Term: transnational**
> Extending across national borders and affecting more than one country.

**Fukushima Daiichi** happened on **11 March 2011** in **Japan**. It was triggered by a **magnitude 9.0 earthquake and tsunami**, which cut power and cooling systems, leading to meltdowns in three reactors.

> **Key Term: Fukushima Daiichi disaster**
> The 2011 nuclear accident in Japan caused by earthquake-tsunami damage to reactor cooling systems.

The distinction between Chernobyl and Fukushima is often tested indirectly. Chernobyl mainly reflects design and operator failure within a Soviet reactor system. Fukushima mainly reflects natural disaster damage to cooling systems in an advanced industrial country. Both were rated **Level 7** events, but their causes were different.

That distinction matters in analysis. If you just write “nuclear power is dangerous,” you stay too general. Better analysis explains _how_ the danger appeared under different conditions: one through unsafe management and reactor flaws, the other through environmental shock overwhelming safeguards.

> **Test Tip:** When comparing Chernobyl and Fukushima, do not treat them as identical. Use the contrast: Chernobyl = flawed reactor design and operator failure; Fukushima = earthquake-tsunami and cooling loss.

After **Chernobyl**, anti-nuclear politics strengthened in Europe. After **Fukushima**, countries reassessed nuclear policy again. **Germany** accelerated its phaseout. **Japan** temporarily shut reactors and tightened regulation. Yet some countries, especially **China**, continued expanding nuclear power. That shows another continuity: even after disasters, states still pursued energy security and modernization.

### Continuity and change in a globalized energy world

This subtopic works best when organized around both sides of CCOT.

Changes after 1900:

- petroleum became central to transport, mass production, and mechanized warfare
- producer states gained more influence through organizations like OPEC
- resource control shifted in some places from foreign firms to national governments
- nuclear energy emerged as a new civilian power source
- energy politics became more global, with local disruptions causing worldwide economic effects
- environmental awareness expanded because pollution, oil spills, and reactor accidents had visible large-scale consequences

Continuities after 1900:

- states still competed over strategic resources and technologies
- powerful countries still sought influence in resource-rich regions
- industrial growth still depended on high energy consumption
- economic development still carried environmental costs
- governments still used control over energy systems to strengthen state power

A strong AP argument might say that globalization transformed energy by making petroleum markets and nuclear technologies central to economic growth and diplomacy, but it did not end older struggles over sovereignty, security, and resource control.

Petroleum and nuclear energy also make a strong comparison. Petroleum depended on extraction, transport, and global markets. Nuclear energy depended more on scientific expertise, regulation, and infrastructure. Petroleum produced routine air pollution and greenhouse gases. Nuclear power reduced direct fossil-fuel burning during operation, but carried accident and waste risks.

That comparison helps move beyond description. It shows that different technologies solve some problems while creating others. That is exactly the sort of balance AP essays reward.
