Although the United States and Iran have stepped back from the brink of a full-scale war, the ceasefire that followed nearly four months of fighting continues to face pressure amid renewed tensions surrounding the Strait of Hormuz. One consequence of the crisis, however, has already become clear: the shift toward clean energy is accelerating, and there are few signs that it will slow down.

The latest conflict is only the newest in a series of disruptions that have shaken global oil and gas markets in recent years, prompting governments around the world to reassess their dependence on imported fossil fuels and highlighting the energy security benefits offered by solar power.

No region was more exposed to a closure of the Strait of Hormuz than Asia. Before the United States and Israel launched their joint military campaign against Iran on February 28, roughly one-fifth of global oil and gas trade passed through the strait each day, moving eastward from the Gulf.

Of the approximately 20 million barrels of oil and petroleum products that flowed through the waterway daily before the conflict, around 80% of the oil and 90% of the natural gas was destined for Asian markets.

When the strait was closed in response to the military campaign, Asian economies were among the first and hardest hit as energy supplies were disrupted. Southeast Asia proved particularly vulnerable because of its heavy reliance on imported energy and its limited ability to absorb major price shocks.

The consequences were not merely theoretical. The Philippines declared a national energy emergency in March, while governments across the region adopted measures ranging from energy rationing and remote work policies to four-day workweeks in an effort to ease the strain.

Yet the same crisis also triggered a long-awaited renewable energy boom that could ultimately leave the region more secure, more independent, and better positioned to control its own energy future.

Rooftop solar systems are expanding rapidly across countries such as the Philippines, Indonesia, Cambodia, and Malaysia, as households and businesses search for alternatives amid rising energy costs and growing concerns over grid reliability.

The trend reflects a broader shift in how governments view energy security. Historically, fossil fuels were considered the most dependable source of power, while solar and wind energy were often viewed as less reliable because of variable output and relatively immature supply chains.

That perception is now changing.

After months of energy disruptions linked to the Strait of Hormuz, renewable energy is increasingly being viewed as the more resilient option and one that is less vulnerable to geopolitical risks.

David Frykman, general partner at Swedish venture capital firm Norrsken, wrote in an opinion article for Fortune: Solar and wind power cannot be embargoed, blockaded, or cut off by a foreign power. Every terawatt-hour of domestic renewable energy is a terawatt-hour that no adversary can weaponize.

Oil and gas must be sourced from countries with large natural reserves, creating geopolitical chokepoints such as the Strait of Hormuz. Solar and wind power, by contrast, are far more decentralized and can be generated in varying degrees across most regions where people live.

Beyond these strategic advantages, solar energy has also become the worlds cheapest source of electricity, making the transition toward renewables both an economic and political necessity for countries such as Indonesia and the Philippines, which have already felt the consequences of heavy dependence on imported energy.

The discussion is no longer solely about climate change. Solar power is increasingly viewed as a practical solution from both an economic and geopolitical perspective.

As Forbes previously noted, For years, clean energy was framed as a moral imperative. Now it is simply an economic and geopolitical necessity. This is not just about emissions; it is about resilience and price stability.

The transformation is likely to do more than shield Southeast Asian energy systems from volatility in global fuel markets. It could also reshape influence within the global energy sector, shifting part of that power toward China.

Chinas dominant position across renewable energy manufacturing and supply chains places it in a strong position to become an increasingly indispensable trading partner for emerging economies pursuing energy independence.

The Philippines offers one of the clearest examples. The country has become the second-largest destination for Chinese solar exports this year, behind only the Netherlands and ahead of Pakistan, traditionally one of the largest buyers of Chinese solar equipment.

According to energy think tank Ember, Chinese solar panel shipments to the Philippines exceeded 4,000 megawatts during the first four months of 2026 alone.
