India-specific Context Capacity: India’s installed data-centre capacity has nearly tripled from ~520 MW (2020) —> ~1.5 GW (mid-2025) —> projected 4.5–6.5 GW by 2030. Investment: Around USD 95 billion committed (2019–25). Expansion driven largely by AI, cloud computing and digitalisation. Way Forward: PUE/WUE benchmarks + renewable energy + recycled/non-potable water + waste-heat recovery + mandatory water/carbon disclosure + location based on local water/grid carrying capacity.

AI DATA CENTRES: DEVELOPMENT vs RESOURCE SUSTAINABILITY Why in News: Residents in Thane (Maharashtra) and Visakhapatnam (Andhra Pradesh) have opposed proposed AI/data-centre projects over their water, electricity and environmental footprint. Key Concerns -Water Stress: Huge cooling-water requirement can compete with drinking and domestic needs, particularly in water-stressed cities. -Energy Burden: Data centres already account for around 1.5% of global electricity consumption, likely to rise sharply with AI. -Urban Impact: Concerns include noise, waste heat, pressure on local grids, sewerage and other civic infrastructure. -Land & Ecology: Large land requirement and associated infrastructure can create ecological and livelihood costs. -Governance Deficit: Protests highlight inadequate public consultation, transparency and cumulative environmental-impact assessment. Takeaway:- India’s AI ambitions require not merely more computing infrastructure, but “resource-efficient and grid-responsive” data centres.
