Southeast Asia’s recent uptick in coal usage is largely perceived as a temporary measure to address energy supply disruptions, according to a survey by the Sustainable Energy Association of Singapore (SEAS). The survey, which gathered insights from over 100 energy professionals, revealed that 68% consider the coal increase a short or mid-term response to energy security concerns, with only 6% viewing it as a significant regression.
Conducted amidst geopolitical tensions affecting energy supply, the survey highlighted that 90% of respondents experienced business impacts, with 59% describing these as moderate or significant. The most common response to these disruptions was a heightened interest in local or regional energy solutions, noted by 39% of participants, whilst 38% reported delays in clean energy investments.
The findings underscore the region’s infrastructure challenges, with over 70% identifying grid infrastructure and regional connectivity as critical hurdles in the energy transition. Additionally, the survey noted the growing role of artificial intelligence (AI) in the sector, with 60% of respondents either piloting or implementing AI solutions.
SEAS Chairman Edwin Khew remarked, “The return to coal is a temporary solution during a time of heightened supply shortage. The industry remains focused on medium to long-term renewable capacity goals.”
The survey, titled ‘The State of the Energy Transition Survey 2026’, was conducted online between July and August 2026. It coincides with the upcoming Asia Clean Energy Summit, which will focus on energy security and AI from 27 to 29 October in Singapore.
