Meta incorporates its proprietary AI-enhanced, carbon-reduced 'eco-concrete' in a colossal data center of theirs
In an era where digital infrastructure such as AI, video streaming, and cloud computing are increasingly powering our daily lives, the energy consumption and water usage of data centers, particularly those owned by tech giants like Meta, have become a significant concern. However, Meta is actively pursuing initiatives to reduce these impacts.
**Energy Consumption and Renewable Energy Initiatives**
Meta's data centers are energy-intensive, requiring vast amounts of electricity to power servers and cooling systems. In 2024, U.S. data centers consumed approximately 239 terawatt-hours (TWh) of electricity, almost as much as the entire state of Florida uses annually, with a lot still coming from fossil fuels [1]. To address this, Meta achieved 100% renewable energy for its global operations in 2020, powering all data centers and offices with clean electricity [1].
Meta is not resting on its laurels. The company is aggressively expanding its clean energy footprint, with plans to add 9.8 gigawatts (GW) of renewable energy to U.S. grids by the end of 2025 [1]. By building facilities near renewable energy sources and focusing on direct clean energy deals linked to its climate goals, Meta aims for energy efficiency.
**Water Usage and Impact**
Data centers consume significant amounts of water primarily for cooling systems, not the computing process itself. This water consumption has raised concerns in areas like Texas, where water scarcity is a critical issue [2]. Meta's expansion of data centers has been linked to water shortages in some communities, and its large AI data centers in particular demand massive water usage [3][5].
Local communities and environmental groups have expressed concerns over water resource depletion, especially when data centers draw water from aquifers used by residential wells [2].
**Meta’s Water Sustainability Initiatives**
Meta has committed to becoming water positive by 2030, meaning it aims to restore more water to the environment than its data centers consume. This involves projects like river restoration and wetland conservation to replenish water resources [2][3].
Despite this commitment, the challenge remains significant as gigawatt-scale data facilities will put strain on local water resources, and critics emphasize the need for local water neutrality rather than offsets that occur far away from the point of use [2].
**Addressing the Challenges**
The scaling demand from AI and other data-intensive technologies continues to pose ongoing sustainability challenges. Meta is linked to a collaboration with cement manufacturer Amrize and the University of Illinois Urbana-Champaign to develop an AI-optimised, lower-carbon "green concrete" for its data centers [4].
Meta is also using AI to design concrete mixes that are stronger and more sustainable, with an AI model specialising in Bayesian optimisation and adaptive experimentation [4]. Modern data centers are predicted to draw such a huge amount of wattage that it's difficult to see how renewable energy can possibly keep up [6].
Meta's CEO, Mark Zuckerberg, announced plans to build several multi-gigawatt superclusters, the first of which, Prometheus, is due to come online next year [7]. The data center at Rosemount is currently housing some of the racks in tents while waiting for the buildings to be finished [7].
In conclusion, Meta's efforts demonstrate a significant commitment to reducing the environmental impact of its data centers, particularly through renewable energy use and water restoration goals. However, the scaling demand from AI and other data-intensive technologies continues to pose ongoing sustainability challenges.

- Meta's objectives extend beyond renewable energy, as the tech giant aims to become water positive by 2030, focusing on replenishing more water to the environment than their data centers consume.
- To address the water usage issue, Meta is collaborating with various entities like cement manufacturer Amrize and the University of Illinois Urbana-Champaign to develop AI-optimized, lower-carbon "green concrete" for its data centers.
- In the realm of climate-change and environmental-science, Meta is using AI to design concrete mixes that are stronger and more sustainable, employing an AI model specializing in Bayesian optimisation and adaptive experimentation.
- The technology sector's increasing reliance on data-and-cloud-computing has led to concerns over the unsustainable amount of energy consumption, making it challenging to keep up with the renewable energy production needed to power these facilities.
- Meta's ongoing commitment to sustainable practices includes the implementation of science-driven solutions in areas such as data center design, energy efficiency, and water conservation, all with the ultimate goal of mitigating climate-change impacts.
