India's AI Boom Fuels Data Center Growth, Straining Water and Energy Resources
India's rapid expansion as an AI hub is leading to a significant increase in data center capacity, projected to reach 13.56 GW by 2031-32. This growth, however, comes with substantial environmental costs, particularly a soaring demand for water and electricity. Data centers are estimated to have consumed around 150 billion liters of water in 2024-25, a figure expected to more than double by 2030, exacerbating water scarcity issues in many regions across the country. The immense energy requirements also strain the power grid, with AI-specific data centers demanding significantly more power than traditional ones. This situation has sparked concerns and protests in various locations as the country races to meet its digital ambitions.

India's ambition to become a global hub for Artificial Intelligence (AI) is driving a massive expansion of data centers, but this digital race is casting a long shadow over the nation's environmental resources, particularly water and electricity. Projections indicate that India's data center capacity, which stood at approximately 1,500 MW by 2025, is expected to surge to a staggering 13.56 GW by 2031-32. This exponential growth is fueled by substantial investments, with major players like Adani and Reliance alone committing over US$210 billion to AI infrastructure and renewable energy by 2035. The IndiaAI Mission has already onboarded thousands of Graphics Processing Units (GPUs) across various cities, highlighting the rapid pace of development. However, this digital surge comes at a steep environmental price. Data centers are notoriously water-intensive, primarily for cooling purposes. In India, data centers consumed an estimated 150 billion liters of water in 2024-25, a figure that is alarmingly projected to more than double to approximately 358 billion liters by 2030. This escalating water demand is particularly concerning given that India is already grappling with severe water scarcity, with an estimated 600 million people facing high to extreme levels of water stress. Many of these new data center projects are being planned in water-stressed regions, further intensifying the pressure on local water supplies. For instance, Chennai, which has experienced severe water crises, remains a sought-after location for server farms. Similarly, Bengaluru's data centers consume over 26 million liters annually, even as the city faces its worst water crisis in decades. Hyderabad also faces a projected deficit, yet Amazon continues its expansion there. This situation has led to significant local resistance and protests in various locations, including Vishakhapatnam and Thane, raising concerns about the environmental impact and resource strain. The sheer volume of water required by hyperscale data centers, some consuming up to 2 million liters per day per 100-megawatt facility, adds to the global 'water bankruptcy' fears. Beyond water, the energy demands of AI data centers are equally concerning. AI workloads, driven by high-performance GPUs, generate significantly more heat and require more power than traditional computing. An AI-heavy facility can demand two to three times the power density of a conventional data center. This puts immense pressure on India's power grid. Projections suggest that AI data centers could add 26.3 GW of electricity demand by 2031-32, making it one of the largest discrete electricity demand additions ever planned in the country. The increasing reliance on electricity, often generated from fossil fuels, also contributes to carbon emissions, further exacerbating climate change concerns. While the government is promoting renewable energy and has introduced policies like Green Open Access, the scale of demand may outpace these efforts. The push for advanced cooling technologies like direct-to-chip and immersion cooling is a step towards mitigating water usage, with some facilities adopting these as default choices due to high rack densities and water scarcity. Regulatory benchmarks for Power Usage Effectiveness (PUE) are also driving the adoption of more efficient designs. However, the lack of transparency regarding water consumption figures from many data centers remains a challenge. The article highlights that many data centre policies in India lack sustainability parameters, and investments are often directed towards water-stressed areas. The narrative underscores a critical juncture for India: balancing its digital aspirations with the urgent need for sustainable resource management to avoid a future crisis.
