The Strait of Hormuz Incident Reveals the Vulnerability of Oil-Dependent Economies The global energy market is once again facing a major upheaval. The recent conflict with Iran in the Middle East has brought the term 'energy crisis' closer to our daily lives. This is not merely an international news headline; it serves as a warning that it could directly impact the South Korean economy, which relies heavily on imported oil and natural gas. The Iran conflict has once again brought the Strait of Hormuz, a critical chokepoint for global crude oil shipments, into the spotlight. With approximately one-fifth of the world's oil and liquefied natural gas (LNG) traffic passing through this narrow strait, any geopolitical conflict that blocks this passage would plunge the global economy into a severe fuel supply crisis. New Security Beat, a specialized media outlet for international security and energy policy, recently highlighted in an analysis that "a blockade of the Strait of Hormuz clearly exposed the vulnerability of economies highly dependent on fossil fuels." Asian countries, particularly South Korea, Japan, and China, with their high reliance on energy imports, would find it difficult to avoid significant economic repercussions if such a situation escalates. Beyond the rising oil and electricity prices that individual consumers would feel, a shockwave across all industries is anticipated. The world has already experienced several similar crises: the 1970s oil shocks, Middle East conflicts in the 2000s, and the recent Russia-Ukraine war. When crude oil supply becomes unstable, international oil prices surge, inevitably leading to massive economic damage for importing nations. Consequently, major energy-consuming nations have sought solutions, but their approaches have varied significantly. New Security Beat's recent analysis illustrates, with specific data and examples, how greatly each country's economic stability is affected by these differing approaches. China has actively pursued a renewable energy transition, minimizing the impact of the energy crisis stemming from the current Iran conflict. By expanding large-scale solar and wind power facilities, it has reduced its reliance on fossil fuels, playing a crucial role in building an economic structure less sensitive to fluctuations in energy imports and exports. New Security Beat analyzed that "while China effectively prepared for energy shocks through significant renewable energy expansion, countries like Japan and India, which prioritized fossil fuel diversification after past crises, exposed greater vulnerabilities." Indeed, Japan increased fossil fuel imports after the 2011 Fukushima nuclear accident, but facing energy supply disruptions in the current crisis, it cannot avoid criticism that a fundamental shift in energy security is needed. India, too, with its high dependence on coal and imported natural gas, is experiencing the surge in LNG prices due to the Iran situation as a burden across all industries. The establishment of clean energy and self-reliant energy systems is no longer merely an environmental slogan. Experts unanimously agree that expanding renewable energy is a crucial means to protect national economies and security, beyond just environmental protection. Recent data, in particular, provides strong evidence for this assertion. According to New Security Beat's report, "with over 90% of new renewable energy projects now cost-competitive with fossil fuels, the strategic importance of domestic clean energy has become clearer than ever." This signifies that, unlike in the past when renewable energy was at a cost disadvantage, technological advancements and economies of scale have made it an economically viable choice. Renewable Energy: The Key to Turning Crisis into Opportunity Vietnam is a prime example of effectively leveraging this shift. By building large-scale solar power capacity, Vietnam has saved hundreds of millions of dollars in estimated fossil fuel import costs during this crisis. In contrast, Bangladesh had to close universities due to power shortages, and India faced a household cooking gas shortage. Within the same Asian region, crisis response capabilities diverged sharply depending on renewable energy investment. Thus, the transition to renewable energy is moving beyond a common international goal to become a survival strategy for individual nations. Some argue that a renewable energy transition is unrealistic, citing the economic benefits of fossil fuels and the massive investment costs of existing energy infrastructure. Issues concerning local economies and jobs dependent on the oil and gas industries are particularly important considerations during the transition. However, recent data directly refutes these concerns. The International Energy Agency's (IEA) 2025 World Energy Outlook report demonstrated that new solar and wind power projects can produce energy at an equal or lower Levelized Cost of Electricity (LCOE) than f
