Server Sanctuaries or Net-Zero Derailers? Southeast Asia’s Data Centre Dilemma

Why It Matters

The escalating power and water needs of data centres threaten SEA’s net‑zero targets and raise operating costs for budget‑constrained startups, making sustainable infrastructure a critical competitive factor.

Key Takeaways

• Data centre energy use could triple by 2050 in SEA.
• Cooling consumes up to 40% of data centre power.
• Over 95% of SEA centres still use air‑cooling.
• AI workloads may raise power demand 160%.
• Water‑cooling can cut electricity and water use.

Pulse Analysis

Southeast Asia’s digital economy is on a rapid ascent, driven by a vibrant startup ecosystem that is embracing artificial intelligence at scale. The region’s data‑centre market is expanding at roughly 18.5% per year, a pace that could triple overall energy demand by 2050. Globally, data centres already account for 1‑1.5% of electricity consumption; in SEA, the warm climate amplifies this impact, as cooling systems must work continuously to keep servers within optimal temperatures.

The core of the sustainability challenge lies in cooling. Approximately 35‑40% of a data‑centre’s power draw in SEA is devoted to temperature control, and more than 95% of facilities still depend on traditional air‑cooling methods. This not only inflates electricity use but also drives massive water consumption—about 25 million litres per megawatt annually for conventional systems. While renewable energy and hydrogen fuel cells promise greener power, their intermittency and high upfront costs make them unreliable for the always‑on requirements of cloud services.

Emerging liquid‑ and water‑cooling technologies offer a pragmatic path forward. Closed‑loop water‑cooling can slash both electricity and water usage, enabling higher server density without the penalties of air‑cooling. Countries such as Thailand and Vietnam are already piloting these solutions, signaling a regional shift toward more efficient designs. For startups, selecting cloud providers with robust sustainability credentials and investing in energy‑efficient architectures can deliver cost savings, regulatory compliance, and a stronger brand narrative—all essential ingredients for thriving in a climate‑conscious market.
