BANGKOK (AP) 鈥� The has exposed major risks for Southeast Asia that could cost the region billions of dollars, if it doesn’t diversify sources of energy more quickly, according to an International Energy Agency report released Tuesday.
An overreliance on oil and gas transported through left the region particularly vulnerable to shocks from the Iran war, a 鈥渟tark wake-up call鈥� for its energy security, the report says.
It notes that rising sales of , a renewed interest in and a boom in rooftop solar and other show that the war is spurring change.
But more sweeping reforms are needed. Otherwise, Southeast Asia鈥檚 energy import bill could rise to $245 billion by 2035, tripling from $80 billion in 2024, the report warns.
鈥淒iversification of energy sources and supply routes is now a central priority,鈥� said , the IEA executive director.
Iran war exposes Southeast Asia’s energy risks
The sent Southeast Asia into a state of , leading to higher energy bills and rising inflation.
In a likely setback for efforts to phase out dependence on fossil fuels, the conflict has reinforced the need to rely on coal during times of energy crisis, the IEA said.
The war is also furthering plans for nuclear power in Southeast Asia, but yearslong construction and regulatory processes remain. Indonesia, Vietnam and the Philippines may be the furthest along with nuclear power plans, but their timelines are uncertain.
鈥淭his energy shock is prompting not just the short-term responses. But a deeper reassessment of policy priorities and investment strategies by governments,鈥� said Sue-Ern Tan, head of the IEA Regional Cooperation Centre in Singapore.
Do-it-yourself approaches an option
In the Philippines, which declared a , consumers have turned to , as a quick, do-it-yourself solution to rising utility bills.
鈥淭his is the first time I’ve seen a demand shock of this magnitude,鈥� said Ivan Cano of the Manila-based solar company EcoSolutions.
The Philippines became the second-largest destination for in the first quarter of 2026, the IEA found. Imports were around three times higher than the same period last year.
Consumers have also driven a shift in Southeast Asia’s transportation industry.
Electric vehicle sales more than doubled in 2025 to around half a million units, according to the IEA, which found that one in five cars sold regionally is electric.
Last month, Laos banned the import of fuel-powered vehicles for the rest of 2026 to cut oil imports and encourage the shift to EVs.
鈥淭he IEA report clearly highlights that Southeast Asia is at a crossroads,鈥� said Sam Reynolds of the U.S.-based Institute for Energy Economics and Financial Analysis, or IEEFA.
Despite the to , fossil fuel prices will likely remain high which means 鈥渨e will see a push towards more ambitious clean energy deployment,鈥� Reynolds said.
IEA says reducing fossil fuel demand is key
To overcome its weaknesses, Southeast Asia needs to reduce its overall demand for imported fossil fuels, the IEA said.
It suggests making more efficient and boosting investment in all forms of renewable energy, such as solar, wind, hydro and geothermal power.
The IEA also recommended prioritizing regional energy sharing initiatives like the Association of Southeast Asian Nations Power Grid. The wake-up call from this energy crisis will hopefully help neighboring nations overcome the political barriers that have hindered the project, Birol said.
鈥淭he Middle East conflict is both a stress test of Southeast Asia鈥檚 current energy system and a catalyst to accelerate structural change,鈥� the report said.
