CLAT Relevance
• GK Section — Data centre energy consumption, water crisis, India’s clean energy commitments
• Legal Reasoning — Environmental policy gaps, regulatory fragmentation, technology vs ecology
• Key Numbers — 945 TWh by 2030, 12% annual growth, 2.5 GW capacity, 6x Denmark’s water use

The Scale of the Problem
While India pushes ahead with ambitious AI programmes, a critical bottleneck looms: the massive energy and water demands of data centres.
- Global data centre energy consumption is growing at 12% annually
- Projected global data centre electricity use: 945 TWh by 2030 — roughly equal to Japan’s entire electricity consumption
- AI workloads are far more energy-intensive — training a single large language model can consume as much electricity as 100 American homes use in a year
Water Crisis Linked to AI
Key Facts — Water Consumption
• Global data centre water usage is now 6 times the total water consumption of Denmark
• A single large data centre can consume 3-5 million litres of water daily
• In water-stressed regions like western India, this creates direct conflict with agricultural and domestic water needs

India’s Data Centre Landscape
- Installed capacity projected to reach 2.5 GW by 2027
- Major hubs: Mumbai, Chennai, Hyderabad, Pune, and the Delhi-NCR corridor
- India currently lacks a comprehensive national data centre policy — regulation is fragmented across state-level approvals
Grid Stress and Power Challenges
- Peak demand spikes in data centre corridors are straining local distribution networks
- Many data centres still rely on diesel generators as backup — contradicting India’s clean energy commitments
- The absence of an integrated AI-energy policy means growth is proceeding without coordinated power planning
Proposed Solutions
Policy Solutions Being Discussed
• Nuclear Small Modular Reactors (SMRs): Compact nuclear power solutions for data centres
• Renewable energy mandates: Requiring data centres to source a minimum percentage from clean energy
• Water recycling regulations: Mandating closed-loop cooling systems
• National Data Centre Policy: A unified regulatory framework replacing fragmented state-level approvals
