Escalating tensions in the Middle East are once again rattling global energy markets, posing fresh challenges for Southeast Asia, one of the world's most import-dependent regions for fuel.

Although governments across the region pledged to gradually shift toward renewable energy, the risk of natural gas disruptions and surging prices is intensifying short-term energy security concerns. With gas supplies threatened and prices spiking, several Southeast Asian countries could be forced to lean more heavily on domestic coal resources to safeguard power supply in the near term.

Over the longer term, however, such a shift risks undermining years of decarbonization efforts and could pose a structural challenge to the region's energy transition goals.

Recent disruptions highlight the fragility of the global energy system. Qatar, one of the world's largest liquefied natural gas exporters, saw production at a key facility halted after an attack, triggering a 50% jump in gas prices within a single day.

At the same time, worsening security conditions around the Strait of Hormuz, a vital global energy artery, underscored how oil and gas can quickly become strategic tools in geopolitical conflicts.

Against this backdrop, coal is re-emerging as a fallback option for some governments seeking to prevent industrial shutdowns and social instability.

Unlike oil and gas, which often require long-distance shipping through conflict-prone waters, coal supplies in many Southeast Asian countries rely largely on domestic production or regional trade, making supply chains relatively more controllable and less exposed to external disruptions.

Coal-fired generation capacity in the ASEAN region reached record highs in both 2024 and 2025, and the latest market shock could allow some aging coal plants that were scheduled for retirement to remain in operation.

Countries such as Thailand and Indonesia may opt to extend the lifespan of coal-fired power plants to ease immediate supply pressures, potentially slowing climate progress that relies on the early retirement of coal assets.

Ironically, the market volatility triggered by geopolitical tensions may benefit entrenched interests that support continued reliance on coal and other high-emission fuels. As energy supply chains from the Middle East face disruption, exports from the U.S. fossil fuel industry are increasingly viewed as a seemingly secure alternative.

While Europe turned to U.S. liquefied natural gas to replace Russian supplies, Asian countries risk falling back into dependence on another single supplier, leaving energy prices exposed to ongoing geopolitical conflicts and the interests of private capital.

Fossil fuels are inherently inflationary and closely intertwined with geopolitical tensions. To mitigate systemic risks, the only viable long-term path for ASEAN lies in accelerating electrification and expanding renewable energy deployment.

For Southeast Asian economies, the transition toward renewables is not only about fulfilling climate commitments but also about reducing reliance on fragile, concentrated fossil fuel supply systems and building a more diversified energy structure capable of withstanding external shocks.

The improving economics of renewable energy are reinforcing its strategic importance. As the levelized cost of electricity (LCOE) for wind and solar continues to fall, these technologies are increasingly capable of shielding energy systems from volatility in global fossil fuel markets.

These issues will likely be discussed in greater detail at the upcoming International Conference for a Just Transition Away from Fossil Fuels, scheduled to take place in April in Santa Marta, Colombia.

Ultimately, addressing the structural vulnerabilities of the global energy system will require abandoning the old model that treats energy as a geopolitical weapon and undertaking a fundamental transformation of the global energy architecture.

Such a shift would require new financial frameworks to support the development of domestic wind and solar resources, allowing countries to decouple energy security from geopolitical instability while protecting workers and communities and ensuring energy is no longer exploited as a tool of conflict.
