Did You Know the Environmental Impact of Scrolling LinkedIn for Just 5 Minutes?
Wait, what?
Environmental impact of scrolling LinkedIn?
Yes, what might seem harmless has a hidden environmental cost.
For a 15-minute session, the data centers running LinkedIn servers can use up to 4-8 glasses of water for cooling (approximately 1-2 liters). For context, that’s about the amount of water you’d use to brush your teeth.
This might seem insignificant at first glance, but multiply it across millions of users on platforms like YouTube, Instagram, and Spotify, and the numbers quickly add up. This brings us to a pressing challenge: finding sustainable ways to reduce water usage in data center cooling.
Guess what?
Microsoft is leading the way with a groundbreaking solution: a data center cooling system that uses zero water.
Currently, each Microsoft data center consumes approximately 125 million liters of freshwater annually. To put that into perspective, it’s enough to provide drinking water to 41 million people in a single day—equivalent to the population of Canada.
But how does it work?
The Zero-Water Cooling Revolution
In August 2024, Microsoft unveiled an innovative zero-water cooling design that aims to drastically reduce the environmental impact of its expanding data center operations. This new system is designed to eliminate the consumption of over 125 million liters of water annually per data center, a major stride in sustainable technology.
At the core of this breakthrough is a “closed-loop” mechanism that recycles water. Instead of relying on a constant supply of freshwater, liquid is added during the construction phase and is then continuously reused within the system. This ensures maximum efficiency and drastically reduces overall water consumption.
Microsoft explains the process in its blog: “By adopting chip-level cooling solutions, we can deliver precise temperature control without water evaporation. While water is still used for administrative purposes like restrooms and kitchens, this design will avoid the need for more than 125 million liters of water per year per data center.”
How It Works
The zero-water cooling system operates by circulating liquid between servers and chillers to dissipate heat. Unlike traditional cooling systems, which often lose water to evaporation, this closed-loop design ensures the same water is reused, conserving resources and enhancing efficiency.
The results speak volumes. In its last fiscal year, Microsoft reported an average Water Usage Effectiveness (WUE) of 0.30 liters per kilowatt-hour (L/kWh)—a 39% improvement compared to the 2021 global average of 0.49 L/kWh. This achievement stems from Microsoft’s ongoing efforts to reduce water wastage, expand its operating temperature range, and optimize data center operations.
The Bigger Picture
While existing data centers continue to employ a mix of air-cooled and water-cooled systems, Microsoft is taking bold steps toward the future. By 2026, the company will pilot its zero-water cooling designs in Phoenix, Arizona, and Mount Pleasant, Wisconsin. These projects will act as proving grounds for the new technology, with full-scale adoption across all new data centers slated for late 2027.
Starting in August 2024, zero-water cooling technology has been integrated into all new data center designs. Microsoft’s environmentally friendly sites are expected to set a benchmark for sustainability in the tech industry.
Why This Matters
Data centers are the backbone of our digital lives. From streaming your favorite shows to scrolling through social media, they enable seamless online experiences. However, this convenience comes with an environmental cost. Data centers are responsible for substantial energy consumption and water usage, making sustainable innovations crucial.
Microsoft’s zero-water cooling system is not just a technological breakthrough; it’s a powerful example of how sustainability and innovation can go hand in hand. By adopting such solutions, the company is not only advancing its own environmental goals but also setting a precedent for the entire industry. As demand for data infrastructure grows, initiatives like these will play a pivotal role in minimizing the environmental footprint of our digital age.
The next time you scroll LinkedIn, think about the unseen efforts powering your experience. With companies like Microsoft at the helm, a more sustainable digital future is not just possible—it’s already in the making.
