In today's digital age, artificial intelligence (AI) stands as a pivotal force in our technological landscape. Yet, alongside its impressive strides, the tech industry grapples with an urgent environmental dilemma.
The proliferation of data centres and the escalating carbon footprint of technology raise sustainability concerns. Nonetheless, advocates contend that if wielded judiciously, AI could offer solutions to tackle these environmental issues.
The stakes are indisputably high. By 2025, estimates project that the tech sector will consume a staggering 20% of global electricity and contribute 5.5% of total carbon emissions. In Belgium, the digital sector alone is responsible for roughly 2% of the country's emissions. This concerning trajectory intensifies with the growing demand for energy-intensive tech applications.
Artificial intelligence presents a distinctive opportunity to confront these environmental challenges spawned by the digital era.
Arun Iyengar, head of Untether AI, a company dedicated to energy-efficient semiconductors for AI, told RTBF about the pivotal choices at hand. "Pandora's box is open,” he said. “We can employ AI to enhance our practices in line with climate demands, or we can opt for inaction and endure the consequences." As servers evolve to meet AI's needs, a transformative era in computing is imminent.
The development of generative AI tools, typified by models like GPT-4 and Google's Palm2, comprises two energy-intensive phases: training and deployment. In 2019, researchers at the University of Massachusetts revealed that training a single AI model emitted emissions equivalent to five cars throughout their entire lifespan.
AI footprint
Recent studies unveil the staggering environmental cost of AI, with GPT-3 alone emitting 552 tons of carbon, equivalent to a car driving two million kilometres. With successors like GPT-4 boasting more parameters, it's clear that AI's environmental impact will expand with its power and prevalence.
At the core of AI's energy appetite are graphics processors, notorious for their energy demands during training. However, the environmental toll extends beyond training, as deploying generative AI tools in the cloud consumes substantial energy through user requests. Addressing this environmental challenge necessitates a comprehensive approach, spanning from initial training to ongoing AI implementation.
For some tech visionaries, the environmental concerns tied to AI pale in comparison to its potential to revolutionize sustainability. Sam Altman, the founder of OpenAI, envisions a future where robust AI can offer solutions to global challenges, such as climate change and clean energy production. The prospects are boundless, from optimizing energy production to global-scale carbon capture.

Jensen Huang, CEO of Nvidia, presents another viewpoint. He told RTBF that widespread AI deployment and faster computations could reduce the need for cloud services, consequently cutting the sector's energy consumption. This shift could transform everyday devices like laptops, smartphones, and cars into energy-efficient supercomputers, reducing the reliance on constant data retrieval from the cloud.
Unbridled risks?
While some industry leaders remain optimistic about AI's potential to combat environmental issues, others caution against complacency. The unbridled pursuit of innovation may inadvertently divert attention from pressing environmental risks.
As large corporations heavily invest in AI deployment, they may not fully grasp the far-reaching environmental implications. Nevertheless, as Arun Iyengar suggests, awareness of these consequences is likely to grow, prompting the tech industry to adopt more environmentally responsible practices.
AI's environmental impact on our digital world is undeniable, but it also offers an opportunity for positive change. By addressing the energy-intensive nature of AI development, optimizing server technologies, and embracing sustainable practices, we can leverage AI's power to mitigate its own environmental footprint.
The choice is before us: harness AI as a force for sustainability or neglect its potential and bear the ecological consequences. In the pursuit of a sustainable digital future, the time for responsible AI innovation is now.
