Artificial intelligence (AI) is transforming our lives—from smart assistants to autonomous vehicles, AI gadgets are everywhere. But there’s a hidden cost to this technological revolution, i.e., AI water consumption impact. While we celebrate AI’s advancements, its environmental footprint, particularly on water resources, often goes unnoticed. The data centers powering AI consume massive amounts of water, contributing to global scarcity.
Figure: Water Usage by Data CentersThis infographic illustrates the primary reasons for water consumption in data centers—mainly for cooling—and provides estimates of water use per kilowatt-hour of electricity and per gigabyte of data. It highlights how factors like location, energy source, climate, and data center design influence water use, with estimates showing that 1 GB of data may use up to 200 liters of water, translating to approximately 20 nanoliters per byte. (Shehabi et al., 2021; Glanz, 2011).
In this blog, we’ll explore the facts, highlight real-world examples, propose solutions, discuss sustainable practices, and dive into a case study showing how innovation can help and AI on water consumption impact.
The Problem: AI’s Hidden Water Footprint
Artificial intelligence depends heavily on data centers—huge buildings packed with servers that handle massive amounts of data every second. These servers give off a lot of heat, so they need powerful cooling systems to stay functional. Many of these cooling systems rely on water, and the demand is massive. In fact, a single AI-focused data center can use enough water in one day to meet the daily needs of around 6,500 households (Shead, 2023).
This issue is growing more serious, especially as more than 160 new data centers are being built globally, many of them in regions already facing water shortages (Shead, 2023). Major tech companies play a big role in this trend. In 2022, Google used about 5.6 billion gallons of water, and two-thirds of its new data centers were located in water-stressed areas (Google, 2023). Microsoft, another AI leader, saw its water usage increase by 34% in just one year, largely because of the resources needed to train advanced AI systems (Microsoft, 2023).
These figures highlight a growing concern about AI consumption impct. As AI technologies expand, they are putting increasing pressure on Earth’s limited water resources.
Solutions: Reducing AI’s Water Impact
The good news? There are ways to tackle this problem. One solution is optimizing data center operations. By using AI to fine-tune cooling systems—adjusting water use based on real-time temperature data—companies can slash consumption without sacrificing performance. Another idea is relocating data centers to regions with abundant water or pairing them with renewable energy sources that don’t compete with water supplies. Technologies like closed-loop cooling systems, which recycle water instead of evaporating it, also offer a practical fix.
A Commitment to reduce AI water consumption impact
Some tech leaders are stepping up with ambitious goals. Microsoft, Google, and Meta have pledged to become “water positive” by 2030, meaning they’ll replenish more water than they use. This involves funding watershed restoration projects, boosting operational efficiency, and adopting water-saving tech. While these promises are encouraging, their success hinges on transparency and follow-through.
Case Study: Iron Mountain’s Innovative Cooling
A shining example of sustainable design is the Iron Mountain data center in Pennsylvania. This facility taps into an underground lake for cooling, cutting its reliance on local water supplies. By leveraging this natural resource, Iron Mountain reduces its environmental impact while keeping servers humming. It’s a smart, scalable solution that proves innovation can align AI’s growth with sustainability.
Call to Action: Your Role in the Solution
AI’s water footprint affects us all, but we can make a difference. Support companies prioritizing water conservation, advocate for stricter regulations, and think twice about the environmental cost of your AI-powered devices. Together, we can ensure that AI’s future is as sustainable as it is groundbreaking. If you want a detailed blog on the regulations comment below.
