Energy Crisis
Overview
An energy crisis refers to a situation in which the supply of core energy resources such as oil, gas, and electricity fails to keep pace with demand, or in which prices surge, inflicting severe damage across the economy, industry, and daily life. It is characterized not merely as a temporary price fluctuation but as a structural phenomenon in which supply chain breakdowns, geopolitical conflicts, and policy failures become intertwined in complex ways. In recent years, its manifestations have grown even more complex as they intersect with the task of energy transition aimed at responding to the climate crisis.

Concept and Types
Energy crises are broadly divided into three types. The first is the supply shock type, in which oil and gas supplies plunge due to production cuts by oil-producing nations or war. The second is the demand surge type, exemplified by cases in which electricity demand spikes due to economic recovery or extreme weather (cold waves, heat waves). The third is the price spike type, in which speculation in financial markets or policy uncertainty distorts prices. Actual crises often unfold as compound crises in which all three types appear simultaneously.
Main Causes
- Geopolitical conflict: Representative examples include the Russia-Ukraine war, instability in the Middle East, and risks involving the Strait of Hormuz.
- Aging energy infrastructure: Aging power plants, transmission grids, and gas pipelines, along with insufficient investment.
- Climate change and extreme weather: Sharp fluctuations in heating and cooling demand, and reduced efficiency of hydroelectric and nuclear power generation.
- Transitional gap in the energy transition: A mismatch between reduced investment in fossil fuels and the pace of expanding renewable energy.
- Policy failures and market distortions: Abuse of subsidies, price controls, and regulatory uncertainty.
Historical Cases
The First Oil Shock of 1973, triggered by OPEC's oil embargo, sent oil prices soaring severalfold and brought stagflation to the global economy. Representative examples include the Second Oil Shock following the 1979 Iranian Revolution, the 1990 Gulf War, the California electricity crisis of the early 2000s, and the 2021 European natural gas crisis. After Russia's invasion of Ukraine in 2022, Europe underwent a rapid reorganization of its energy security aimed at escaping dependence on Russian gas.
Economic and Social Impacts
Energy crises reduce households' real incomes through inflation and raise cost burdens for manufacturing, adversely affecting productivity and employment. Energy-intensive sectors (steel, chemicals, cement, semiconductors) are especially sensitive, and crises can lead to deterioration of the trade balance and depreciation of the currency. Socially, they expand the population suffering from energy poverty, intensify competition among countries to secure resources, and can even trigger political instability.
Responses by Country
The European Union lowered its dependence on Russian fossil fuels and expanded investment in renewable energy and energy efficiency through the REPowerEU plan. The United States responded by releasing strategic petroleum reserves (SPR) and expanding shale production, while Japan and South Korea combined the restart of nuclear power plants with energy-saving policies. China has adopted a dual strategy of maintaining coal-fired power generation while expanding renewable energy facilities on the world's largest scale.
Latest Trends
The energy crisis of 2024-2025 is unfolding in conjunction with a new variable: the surge in electricity demand driven by AI data centers. As the spread of generative AI caused data center power consumption to soar, the problem of insufficient grid capacity came to the fore in major countries in the United States, Europe, and Asia, leading to a reevaluation of nuclear power (especially SMRs) and gas-fired generation. At the same time, in 2025, the increasing frequency of heat waves and cold waves due to climate change is threatening the stability of power systems. Geopolitically, the prolongation of the Russia-Ukraine war, Middle East tensions, and changes in U.S. tariff and energy policies are heightening supply chain uncertainty. Energy security is now expanding beyond the simple securing of resources into a compound security concept encompassing critical minerals, batteries, power grids, and semiconductor supply chains, and countries are making energy self-reliance, diversification of supply sources, innovation in energy efficiency, and securing grid flexibility their core tasks.
