The Ministry of Electronics and Information Technology, along with global technology majors Amazon Web Services, Microsoft, and Google, is steering an aggressive expansion of India's digital infrastructure despite rising global alarm over the massive environmental cost of artificial intelligence.
While public anxiety over water consumption and power grid stability surges in the United States, Indian authorities are actively moving to counter fears that local water supplies will be drained by upcoming hyperscale facilities.
Public Anxiety Mounts in the United States
An AP-NORC survey reveals widespread public worry across American cities over the compounding resource demands of generative AI models. Cooling server infrastructure requires millions of litres of fresh water daily. A medium-sized facility consumes upwards of 37 to 38 crore litres of water every year when using traditional evaporative cooling systems.
With nearly two-thirds of recently built American facilities situated in water-stressed regions, local communities face the grim prospect of depleted aquifers and a heavier reliance on fossil fuels to satisfy energy-hungry server racks.
India Counters Fears With Closed-Loop Systems
Senior government officials in New Delhi dismissed claims that expanding infrastructure will automatically deplete domestic drinking water as misplaced. Officials explained that concerns stem from outdated evaporative techniques that dump water vapor into the atmosphere.
Upcoming Indian facilities are mandated to adopt direct-to-chip liquid cooling and closed-loop systems that recirculate water internally. This design drops operational freshwater consumption to negligible levels. In key emerging hubs like Visakhapatnam, facilities will run on industrial wastewater, treated sewage effluent, or dedicated desalination plants backed by industrial allocations from Godavari and Polavaram river diversions.
Tax Incentives Acceleration and UN Estimates
Policy support from Union Finance Minister Nirmala Sitharaman, including a landmark tax break extended through 2047 for cloud and data infrastructure, has positioned India as a magnet for digital capital. India added 387 megawatts of capacity in 2025 alone, with total investment pipelines touching nearly $90 billion (approximately ₹7.5 lakh crore) a sixfold jump over previous years. Major hubs in Mumbai, Hyderabad, Delhi-NCR, Bengaluru, and Chennai currently account for 65 per cent of total national capacity.
However, environmental researchers from the United Nations University warn that technological safeguards face a daunting scale challenge. Generating a single AI image consumes roughly 29 millilitres of water. Multiplied across hundreds of millions of daily user prompts worldwide, the cumulative physical footprint presents a serious ecological challenge that demands continuous oversight.
