Southeast Asia’s artificial intelligence boom is quietly setting up a climate crisis. As hyperscalers and cloud providers race to build data centres across the region, the power demand they generate is on a collision course with Asean’s decarbonisation targets, and the current grid simply cannot absorb the shock.
A new report from Earth Venture Capital finds that Southeast Asia’s data centre market is projected to reach US$30.47 billion by 2030, growing at a CAGR of 14.24 per cent. Yet power generation across the region is expanding at less than 7 per cent annually, and approximately 70 per cent of the Asean grid still runs on coal and gas. The math is stark: the AI buildout is being powered by fossil fuels, and the emissions consequences are accelerating.
Nowhere is the risk more visible than in Malaysia, where data centre electricity demand is set to surge from 8.5 TWh in 2024 to 68 TWh by 2030, representing up to 30 per cent of the country’s national power supply. Without a clean baseload solution, Malaysia’s data centre emissions could rise sevenfold within the decade.
Renewables alone cannot close this gap. Solar and wind, while important, face what the report terms a “solar plateau”, intermittency and land constraints that limit their share to roughly 30 per cent of projected demand. The report assesses nuclear energy and small modular reactors (SMRs) in particular, as the only technology capable of delivering firm, low-carbon power at the scale and speed this transition demands.
With zero operating commercial reactors across Southeast Asia today, the window to act is narrow, and the decisions made in the next five years will determine whether the region’s AI ambitions accelerate or undermine its climate commitments.
