The suburbs of northeast Paris are home to a massive terra-cotta-colored warehouse that houses one of France’s newest data centers. This facility, known as PA10 and owned by Equinix, is buzzing with the noise of cooling systems working tirelessly to keep the clients’ computer servers at optimal temperatures. The scale of the facility is evident from the rows of gray doors and the windowless corridors that create a labyrinthine structure.
One of the unique features of the PA10 data center is its use of hot air waste to heat water, which is then piped to a local energy system run by French utility company Engie. This innovative approach allows Equinix to export 6.6 thermal megawatts of heat out of the building, equivalent to heating more than 1,000 homes. The integration of the data center into the local energy infrastructure demonstrates a commitment to addressing the environmental impact of data centers.
As the demand for artificial intelligence (AI) continues to grow, projections suggest that data centers like PA10 will need to increase their power consumption significantly. Equinix predicts a rise of up to 400 percent in power consumption per rack, highlighting the challenges posed by the AI energy crunch. By repurposing the waste heat generated by the data center, Equinix is not only reducing its environmental footprint but also contributing to the heating needs of the local community.
Despite the environmental benefits of heat reuse projects like PA10, critics argue that they are a distraction from the larger issue of data centers’ overall impact. Anne-Laure Ligozat, a computer science professor at France’s National School of Computer Science for Industry and Business, points out that the focus should be on reducing the number of data centers and their energy consumption. While repurposing waste heat is a step in the right direction, it does not address the fundamental resource-intensive nature of data centers.
The case of Equinix’s PA10 data center in Paris sheds light on the complex relationship between data centers, energy consumption, and environmental sustainability. While the heat reuse project is a positive step towards reducing the facility’s carbon footprint, it is essential to look beyond individual initiatives and address the broader challenges posed by the rapid growth of data centers. By taking a critical approach to the environmental impact of data centers, stakeholders can work towards more sustainable solutions that prioritize efficiency and conservation.
