Data centres serve as the backbone of the internet, processing the vast amounts of data generated with every online action we take. However, the exponential growth in data usage has raised concerns about the environmental impact of these centres. With up to 1-1.5% of global electricity consumption attributed to data centres, and the potential for this to rise to 8% without intervention, it’s imperative to find sustainable solutions to manage their energy usage and mitigate their carbon footprint.
Today, that figure has skyrocketed, with no signs of slowing down, especially with the proliferation of data-heavy technologies like AI. However, amidst these challenges lies an opportunity for innovation and sustainability.
One promising avenue is the redirection of energy produced by data centres, transforming it from waste into a valuable resource that can be reused within a circular energy model. Here, we explore four innovative projects leading the charge in harnessing and repurposing waste data centre energy according to the World Economic Forum:
The Trout Farm in Rjukan, Norway: Hima Seafood and Green Mountain Technology have formed a partnership where renewable energy from data centres powers a trout farm. Utilizing 100% renewable hydropower, a pipe system connects the data centres to the farm, delivering heated water and reducing the carbon footprint of both operations.
The Swimming Pool in Exmouth, United Kingdom: Deep Green, a startup using AI and machine learning technology, provides data centres to businesses. The heat produced by these data centres is channelled to heat the swimming pool in a local leisure centre, significantly reducing energy bills and promoting sustainability.
The Wind Turbines in Paderborn, Germany: WindCORES, a technology company, houses data centres within wind turbines. By directly powering data centres from wind turbines, WestfalenWIND aims to utilize renewable energy to operate a significant portion of data centres in Germany, contributing to a cleaner energy future.
The Residential Homes in Stockholm, Sweden: Stockholm Exergi partners with data centre operator DigiPlex to provide heat to 10,000 apartments in Stockholm. Through the Stockholm Data Parks initiative, Sweden aims to derive 10% of its heat from data centres, driving towards a fossil fuel-free capital by 2040.
These projects highlight the transformative potential of repurposing waste data centre energy for sustainable initiatives. By leveraging innovative technologies and partnerships, we can not only mitigate the environmental impact of data centres but also create new opportunities for renewable energy utilization.
As organizations and nations strive towards renewable energy targets, initiatives like those showcased here pave the way for a greener, more sustainable future. With concerted efforts and collaborative action, we can harness the power of data to drive positive environmental change, setting the stage for a more sustainable digital infrastructure for generations to come.
