The world is abuzz with the potential of artificial intelligence (AI), and at the heart of this excitement lies the datacentre boom. As the global economy races to scale up data centres, the conversation around their benefits and costs has become increasingly urgent. In Australia, the situation is particularly intriguing, as the country attracts significant datacentre investment, driven by the promise of AI. However, the story is far from straightforward, and the costs of this boom are substantial, both economically and environmentally.
The Datacentre Boom: A Global Phenomenon
The numbers are staggering. Worldwide, over 10,000 active datacentres exist, and this number is expected to increase by 3.5 times at an estimated cost of US$7 trillion. This is a significant chunk of the world's annual GDP, and it's not just the US that's leading the charge. Australia is also attracting datacentre activity, with 286 active or planned centres, and global AI leaders like Anthropic setting their sights on the country. The economic, environmental, and social consequences of this boom are profound, yet governments are largely taking a laissez-faire approach, perhaps driven by fear of missing out on the alleged benefits or the desire to avoid upsetting the tech billionaires.
The Cost of Compute: A 7 Trillion Dollar Race
The cost of scaling data centres is a significant concern. The investment required is immense, and the benefits are not immediately clear. While AI has the potential to benefit humanity in numerous ways, from congestion relief in Shanghai to improved diagnosis accuracy worldwide, the costs must be carefully considered. The Australian Prudential Regulation Authority has warned of the accelerating cybersecurity risk posed by AI, and the energy and water consumption of datacentres is a major concern. Australia's datacentres are expected to triple our energy and water consumption by 2030, at a time when the country is racing to electrify using renewable energy and storage.
The Environmental Impact: A Double-Edged Sword
The environmental impact of datacentres is a complex issue. While waste heat from datacentres can be used to heat homes in cold climates like Finland, in most parts of Australia, the warming planet is already leading to more extreme heat days. The collective impact of datacentre emissions must be considered in any cost-benefit analysis, and Queensland's resistance to the federal government's energy principles for datacentres is a cause for concern. The datacentre boom could slow the transition to net-zero emissions and add to energy costs for everyday consumers.
The Economic Reality: A Mixed Bag
The economic benefits of the datacentre boom are not as straightforward as they may seem. While the boom has lifted business investment and driven new capital expenditure, most of the equipment must be imported, meaning the direct effect on the size of the economic pie is minimal. Beyond the construction phase, datacentres do not create many jobs, and the productivity gains from AI are uncertain. The assistant minister for science, technology, and the digital economy, Andrew Charlton, has noted that Australia is at a crossroads, but the country's poor record on commercialising ideas and keeping profits at home suggests that the path to becoming a world-class adopter and creator of AI technology is fraught with challenges.
The Way Forward: A Balanced Approach
As the world grapples with the datacentre boom and the promise of AI, a balanced approach is essential. While the benefits of AI are undeniable, the costs must be carefully considered, and the environmental impact must be addressed. Governments must ensure that technology works for the people, not the other way around. The future of AI and datacentres is bright, but it must be built on a foundation of sustainability and economic responsibility. The race to scale up data centres is a 7 trillion dollar challenge, and the world must navigate it carefully to ensure that the benefits outweigh the costs.
