The Hidden Climate Cost of Your AI Query
When you type a prompt into a chatbot or upload an image for analysis, a network of servers springs to life across the globe. These machines, located in large data centers, use power and water comparable to entire cities. While headlines celebrate the achievements of generative AI, the environmental impact of this technology is a pressing concern.
The Energy Drain: How AI Data Centres Consume Power
The Devouring Demand
AI workloads are extremely power-hungry. The International Energy Agency (IEA) estimates that a typical AI data center uses as much electricity as 100,000 households. As major chip manufacturers build “hyper-scale” facilities for training large models, electricity consumption can soar—some new sites are expected to use twenty times the power of current AI hubs.
From a Fraction to a Dominant Share
In 2024, data centers accounted for about 1.5% of global electricity consumption. This may seem small, but usage is set to more than double by 2030, reaching 945 terawatt-hours (TWh). For context, this amount exceeds half of India’s total electricity consumption for the fiscal year 2023-24 (1,622 TWh). In the U.S., the IEA predicts that data centers will contribute to about half of the nation’s electricity demand growth from 2025 to 2030.
Regional Shockwaves
Europe’s green-energy goals have not shielded it from rising demand. In Ireland, data centers consume around one-fifth of the electricity supply, straining the grid. In China, large AI projects are built with dedicated power lines, but the scale of AI training still stresses regional power systems.

By 2030, it could host up to 6.5 gigawatts (GW) of AI computing power, with investments projected to exceed $100 billion by FY27. However, as of January 2026, data centers made up only 0.5% of national electricity consumption. If growth continues, AI infrastructure could soon rival the electricity use of entire states.
Water Woes: The Unsustainable Demand of AI Infrastructure
Cooling the Cloud
Power consumption is just part of the story. Data-center cooling systems, especially those using evaporative methods, require vast amounts of freshwater. In 2025, Indian data centers used about 150 billion liters of water, equivalent to roughly one-third of Pune’s annual water consumption. This figure is expected to double by 2030, increasing competition for water in stressed regions.
Geography of Scarcity
The water footprint varies by location. In arid areas of western India, where many data centers are being built, groundwater levels are declining. Coastal cities like Mumbai use seawater for cooling, but face higher infrastructure costs and stricter environmental regulations. Ireland’s experience shows that even with ample rainfall, public backlash over water withdrawals can lead to stricter regulations.
Projected Doubling and Its Implications
As water use doubles, the effects extend beyond data centers. Municipal utilities may need to allocate more resources for industrial cooling, potentially raising costs for households and agriculture. Additionally, thermal discharge from cooling towers can raise local water temperatures, disrupting aquatic ecosystems.
India’s Water-Intensive Expansion
The rise of AI facilities coincides with a broader digital infrastructure boom. The Council on Energy, Environment and Water (CEEW) reports that India’s data center count reached 271 by early 2026, with Mumbai as the main hub. As developers seek low-tax zones and cheap land, many are moving to areas with limited water resources, risking a “digital-water” paradox where economic growth threatens sustainability.

This challenge is complicated by India’s fragmented power sector and varying state laws on water rights.
Renewable-Powered Data Centres
One promising approach is to co-locate data centers with renewable energy sources. Solar farms in Rajasthan and wind parks in Gujarat are being considered for direct power purchase agreements (PPAs) with data-center operators. By securing clean energy, companies can reduce peak-load pressures and enhance their carbon-neutral credentials, appealing to clients seeking greener AI services.
Water-Efficient Cooling Innovations
Technological upgrades can help reduce water use. Air-side economizers can cut reliance on water-intensive chillers by up to 70%. Closed-loop liquid cooling systems recycle coolant, minimizing freshwater withdrawal. Incentives like tax credits could encourage faster adoption of these technologies.
Regulatory Levers and Incentives
A clear regulatory framework is essential. The Ministry of Power could require new AI data centers over a certain size to submit a grid impact assessment and a water-use audit before approval. State water departments might implement tiered licensing fees based on water withdrawal, encouraging operators to adopt low-water technologies.
Strategic Perspective: Toward a Sustainable AI Future The appeal of generative AI is clear—it can enhance research, improve services, and create new business models.
International Cooperation and Standards
India’s challenges are not unique. The EU’s “Code of Conduct for Data Centres” and the U.S.’s “Data Centre Energy Efficiency Initiative” provide models for international collaboration. By engaging with these initiatives, India can adopt best practices, harmonize certification standards, and join global carbon-credit markets that reward sustainable data-center designs.
