India is emerging as a global hub for AI data centres. Critically evaluate the water and energy sustainability challenges this poses.

A hyperscale data centre converts almost all the electricity it draws into heat that must be removed continuously — making power and cooling water its twin sustainability pressure points. India's AI-hub ambition therefore promises real gains, but on conditional terms.

The scale of the emerging hub

• Google's 1-GW campus in Visakhapatnam — India's first gigawatt-scale AI hub — involves an estimated $15 billion investment (2026–30), is projected to generate about ₹10,000 crore for Andhra Pradesh and 5,000–6,000 direct jobs [1].
• TCS's separate 1-GW "HyperVault" facility signals that this is a wave, not a one-off [2].

Energy sustainability challenges

• Global data-centre electricity use was about 415 TWh (1.5% of world consumption) in 2024, and is set to roughly double to ~945 TWh by 2030, with AI-optimised demand rising fastest [3].
• A single 1-GW near-continuous load strains state grids and, in India's coal-heavy mix, adds emissions unless matched by round-the-clock renewable supply.

Water sustainability challenges

• Conventional evaporative cooling is water-intensive and can draw on potable supply, competing with drinking and irrigation needs.
• India already has nearly 600 million people under high-to-extreme water stress, with demand projected at twice supply by 2030 (NITI Aayog CWMI, 2018) [4]. Local protests in Visakhapatnam over anticipated water use reflect this [2].

The other side — trade-offs, not dead ends

• Google's shift to air-cooling at Vizag sharply cuts water withdrawal, but imposes an efficiency and performance "tax" — more energy per unit of compute [2]. Water is saved by spending power.
• Direct-to-chip/immersion liquid cooling raises capital cost yet removes heat far more efficiently; renewable-linked power purchase, recycled non-potable water and waste-heat reuse can compress both footprints.

Water and energy stress here flow from design and siting choices, not from digitalisation itself. Mandatory water- and energy-disclosure norms, green-power procurement and siting in water-surplus zones can make India's data-centre boom consistent with SDG-6 and SDG-7 — turning a resource dilemma into a template for sustainable digital infrastructure.
