OPEC's 1973 embargo sparked the first global energy shock.

The 1973 oil embargo by OPEC inspired advances in alternative energy technology

The shortages imposed by the Organization of Petroleum Exporting Countries (OPEC) created a global energy crisis and economic instability after the Arab-Israeli War. This led to investments in green technologies and improvements in automobile fuel efficiency and manufacturing.

The 1967 war was the first use of oil as a geopolitical weapon

Following the June 1967 Arab–Israeli war, Saudi Arabia, Kuwait, Iraq, Libya, and Algeria embargoed oil shipments to the US, UK, and West Germany. While the move did not have a large impact, it reshaped global oil flows, and foreshadowed OAPEC's later actions.

Iran's 1979 revolution sparked a second oil shock—and reconfigured global energy markets.

Oil shocks, war, and the 1970s crisis that remade American energy and economics

The oil crises of the 1970s—fueled by Middle East conflict and OPEC's dominance—triggered inflation, price controls, and policy failure. But they also accelerated fracking, alternative energy, and the rise of free-market economics.

OPEC (the Organization of the Petroleum Exporting Countries) has grown from five to 12 members since 1960.

OPEC can roll out production cuts among its members to control oil’s global supply and price

The Organization of the Petroleum Exporting Countries (OPEC) was created to coordinate and unify petroleum policies to secure fair and stable prices. During the pandemic, for instance, the organization pushed through production cuts in an attempt to stabilize prices.

See a timeline that shows how volatile oil prices have been for decades, from OPEC-led embargoes in the 1970s and shale surges in the 2000s to the US flipping to become a net oil exporter in 2020.

Lessons from the 1973 energy crisis still echo in today’s geopolitical battles over oil

The video from the Economist highlights how energy supply disruptions can be weaponized—just as in 1973, today’s gas cutoffs (Russia throttling supplies to Europe after their invasion of Ukraine) reveal the ongoing importance of strategic energy resilience.

In 2016 OPEC and 10 major producers—including Russia—launched OPEC+

OPEC+ emerged in 2016 when 10 additional producers, including Russia, joined to stabilize markets amid U.S. shale growth. In 2022, OPEC alone supplied 38 % of global crude oil, but combined with OPEC+, output reached nearly 59 % of world production—significantly amplifying its market power.

1970s U.S. energy crisis sparked waves of green innovation

Faced with the 1973 Arab oil embargo, the U.S. responded with bold innovation—enacting a 55 mph speed limit, pioneering daylight saving time, boosting solar research, expanding nuclear power, and pushing energy-efficient building designs and automotive technologies

OPEC often intervenes to influence the price of oil

This guide explains how investing in oil works with in-depth explanations of each of the forces that control oil’s price. Oil is unique as a commodity in part because of OPEC’s role in regulating its price.

In the 1970s, the US experienced a period of stagflation

It was characterized by high inflation, slow economic growth, and high unemployment. The crisis was triggered by a combination of factors, including loose monetary policy that spurred excess demand and spiraling oil prices caused by an OPEC embargo in 1973.

A report found that the 2026 Iran war is the largest oil supply disruption in history.

Oil's legacy: fueling industrial growth and shaping imperial strategies

This episode of The Rest Is History podcast traces oil's pivotal role—from fueling industrial growth to steering imperial power. It also examines how access to oil shaped US politics, World War II, and sparked the creation of OPEC following the Suez Crisis.

Trace the rise of oil: from early drilling to today’s global power

This animated map video vividly illustrates how petroleum shaped global politics and industry—from 18th-century uses and 19th-century drilling booms in North America to today’s OPEC strategies, shale revolution, and geopolitical oil influence.

Beyond oil, the Iran war is pushing up costs on fertilizer, prescriptions, and mortgages, too

Gas is up 27% since fighting began, but the Strait of Hormuz also carries a third of the world's fertilizer, petrochemicals used in generic drugs, and helium for semiconductor manufacturing. Mortgage rates have climbed back above 6.4%, and economists warn $130 oil could tip the U.S. into recession.

View a breakdown of worldwide oil production since 1900, mostly led by the US

When analyzing the production of crude oil, shale oil, oil sands, and condensates since the start of the 20th century, Saudi Arabia produced more crude oil only in 1977, from 1979 to 1981, and from 1991 to 2016. Nations such as Iraq and the United Arab Emirates produced much smaller quantities than both Saudi Arabia and the US.

Explore a timeline of US dependence on crude oil from 1850 to 2023

Oil dependence began with the rise of oil as a commodity, followed by an era of geopolitical competition for the resource after World War II. The domestic fracking boom, which started around 2006, was driven by a desire to reduce the nation's dependence on international adversaries for energy.

Unless prices of fossil fuels rise significantly, their production is expected to slow

US oil and natural gas production skyrocketed from 2000 to 2020, largely due to advances in fracking. However, weak global energy prices have prevented this boom from translating into increased profits for fossil fuel companies.

Oil prices spiked when Russia invaded Ukraine in 2022

The price of a barrel of Brent crude experienced volatility in the early 2020s. This chart shows price spikes at the beginning of the pandemic and again when Russia invaded Ukraine.

Mosaddegh nationalized Iran's oil industry in 1951, threatening Western control of the country's resources

Before nationalization, British companies controlled most of Iran's oil wealth, with little revenue returned to Iranians. Mosaddegh's decision made him a national hero at home but triggered a Western-led embargo and ultimately contributed to the coup that removed him from power.

Oil markets are seeing higher costs and lower prices amid tech breakthroughs

Experts say oil demand has not yet reached its peak. Recent technological breakthroughs in the oil industry include advances in drilling and extraction, as well as subsurface technologies.

Pan Am was once the largest international airline in the US—but it shut down in 1991 after a series of financial issues, beginning with increased operating costs and reduced demand driven by the oil crisis in the 1970s.

The Seven Sisters were a dominant midcentury Western oil consortium

Amid the fallout of World War II, Western multinational corporations expanded their control of the production of oil across the oil-rich Middle East, earning the pejorative nickname of the Seven Sisters. In the 1970s, the group’s role diminished as nationalist movements pursued sovereign control of the oil.

The number of annual oil spills has dropped dramatically since the 1970s

Oil spills from oil tankers—which can have a sharp, short-term impact on oil prices—have become increasingly rare over the decades in part because of stricter regulations.

Oil nationalization triggered the CIA‑backed 1953 coup in Iran

NPR's Four Days in August podcast recounts the four days of covert CIA‑UK operations in Iran that toppled Prime Minister Mossadegh in August 1953. Threats of Iranian oil nationalization were a major driver of the decision to facilitate regime change.

Why have gas prices surged nearly 27% since the Iran war began?

Oil passing through the Strait of Hormuz makes up only about 7% of US crude imports. However, crude oil prices account for 51% of the cost of a gallon of gas in the US. US refiners pay the Brent crude futures price, even for domestic drilling.

Large oil companies knew about the impact of carbon emissions since the ’70s

PBS Frontline’s The Power of Big Oil reveals how industry giants like Exxon and Shell were researching climate change in the 1970s but then funded denial campaigns—using internal science to sow public doubt for decades.

The 1979 Iranian Revolution inspired other Islamist movements and alarmed Sunni governments

By establishing the world's first modern Islamic theocracy, the revolution inspired Islamist movements across the region and alarmed Sunni Arab governments. The resulting rivalry between Shia Iran and Sunni Saudi Arabia has since fueled proxy conflicts in Lebanon, Iraq, Syria, and Yemen that persist today.

How disruptions in oil markets can drive up the price of everyday goods

Most types of plastic are made from polymers derived from chemicals produced by the processing and refining of crude oil and natural gas. Spikes in the cost of either fossil fuel raise the cost of wrappings, tubs, and other plastic containers for products.

Fracking has led to an increased global oil supply, contributing to lower oil prices

Fracking technology has significantly increased how much crude oil the US produces. As more countries adopt fracking technology, there could be an increased downward pressure on prices—although fracking has been widely criticized for its negative environmental impacts.

Breaking down Europe's reliance on Russian energy (preinvasion)

One side effect of the Russian-Ukraine conflict is how it underscored European dependence on Russian natural gas and oil. This article, published days before the Russian attacks, outlines and illustrated how much gas and oil flows from Russia to Europe and the potential for either side to use sanctions to get what they want.

The US stores hundreds of millions of oil barrels in caves along the Texas-Louisiana coast

The US has a Strategic Petroleum Reserve that it taps into, releasing barrels into the economy, during times of emergency (think: major storms and wars) to try to stabilize markets.

Japan attacked Pearl Harbor largely because it was running out of oil

This video traces how US-led sanctions and Japan’s near-total dependence on imported oil pushed Japanese leaders toward a high-risk plan: seize Southeast Asian oil fields and neutralize the American Pacific Fleet, hoping Washington would negotiate rather than fight.

The 1956 Suez crisis was one of the earliest tests of the rules-based order

When Britain, France, and Israel secretly invaded Egypt, the Eisenhower administration supported UN resolutions condemning the invasion and called for a ceasefire—publicly criticizing its closest allies to uphold the principle that force should not be used to resolve international disputes.

Spare capacity is the amount of oil production that can be brought online within 30 days and sustained for at least 90 days

Specifically, a country’s “spare capacity” signifies the difference between its maximum sustainable oil production and its current output. OPEC member countries hold nearly all of the world’s spare oil production capacity. Historically speaking, Saudi Arabia has been the country with the largest spare capacity.
