What Happened
- Data centres across Asia are experiencing explosive growth driven by the artificial intelligence boom, cloud computing demand, and digital service expansion — creating a significant new source of greenhouse gas emissions at a time when the region faces mounting climate stress.
- In the ASEAN region alone, data centre power consumption is projected to grow from 9 TWh in 2024 to 68 TWh by 2030, with individual countries potentially seeing data centres account for 2–30% of national power demand.
- Across Asia-Pacific, electricity consumption by data centres could grow from under 200 TWh in 2025 to over 1,000 TWh by the mid-2030s — a fivefold increase that would represent 2.3% of total regional electricity demand.
- The growth is particularly acute in Malaysia, which is expected to see a sevenfold increase in data centre power consumption from 8.5 TWh in 2024 to 68 TWh by 2030.
- Climate stress — rising temperatures, extreme weather — simultaneously increases cooling energy requirements for data centres, creating a compounding feedback loop between digital infrastructure and climate impacts.
Static Topic Bridges
Data Economy and Digital Infrastructure
The global data economy refers to economic activity generated by the creation, processing, storage, and monetisation of data. Data centres are the physical backbone of this economy — they house servers, storage, and networking equipment that power cloud services, AI models, financial transactions, and internet traffic. As AI applications proliferate, the computational intensity (and therefore energy demand) per unit of digital service has increased sharply.
- AI model training and inference are significantly more energy-intensive than traditional computing workloads.
- Data centre capacity in Asia is growing at approximately 19% annually (2024-2028), driven by hyperscale investments by global tech companies.
- India is emerging as a data centre hub, with cities like Mumbai, Chennai, Hyderabad, and Pune attracting significant investment.
- The Digital Personal Data Protection Act, 2023 and data localisation requirements are expected to further drive domestic data centre investment in India.
Connection to this news: Asia's data centre boom is not merely a technology story — it is an energy policy and emissions challenge. The region's dependence on coal-heavy power grids means that data centre growth, unless met with clean energy, directly translates to higher CO2 emissions.
Energy Transition and Green Power Procurement
The global energy transition — shifting from fossil fuels to renewable sources — is the central climate solution strategy. For data centres, the transition involves power purchase agreements (PPAs) for renewable energy, on-site solar installations, and participation in green energy certificate markets. Major tech companies have made ambitious net-zero and renewable energy commitments, but implementation lags in regions with immature renewable energy markets.
- Amazon Web Services pledged to power 100% of its global operations with renewables by 2025 and achieved this target ahead of schedule in 2023; it contracted 274 MW of renewable capacity in Indonesia and Singapore.
- A third of ASEAN data centres could theoretically be powered by solar and wind by 2030 — but grid infrastructure and regulatory barriers are obstacles.
- India's National Green Hydrogen Mission and Renewable Energy targets (500 GW by 2030) create a policy environment for clean power, but last-mile connectivity for industrial consumers remains challenging.
- ASEAN countries have collectively committed to 32% energy intensity reduction by 2025 under their Nationally Determined Contributions.
Connection to this news: The data centre energy challenge tests the credibility of Asia's energy transition commitments. Without deliberate green energy procurement mandates for large data consumers, the AI boom risks locking in fossil fuel dependence for a decade.
Climate Feedback Loops and Urban Heat
Climate stress refers to the increasing frequency and intensity of heat waves, droughts, floods, and other weather extremes driven by global warming. For data centres — which require intensive cooling to prevent hardware damage — higher ambient temperatures directly increase cooling energy consumption, creating a feedback: hotter climate → more cooling energy → more emissions → hotter climate.
- Data centres typically operate at Power Usage Effectiveness (PUE) ratios of 1.2–1.8, meaning for every unit of energy delivered to computing equipment, 0.2–0.8 additional units are consumed for cooling and infrastructure.
- Asian data centres face particular climate exposure because many are concentrated in tropical or subtropical cities (Singapore, Jakarta, Mumbai, Chennai) where cooling loads are already high.
- Water usage is an additional climate stress point: air-cooled data centres can consume millions of litres of water daily — a resource already under severe pressure in much of Asia.
- The IEA projects that global data centre electricity consumption could double by 2030 if efficiency improvements don't keep pace with demand growth.
Connection to this news: The climate stress dimension is both a cause and consequence of data centre growth. This interconnection makes data centre sustainability a cross-cutting issue spanning energy policy, technology governance, climate adaptation, and urban planning.
