Australia's Datacenter Dilemma: Power, Water, and Economic Growth
In the outer western suburbs of Sydney, a massive datacenter project is proposed, sparking a nationwide debate. This project, known as the Mamre Road datacenter, is a microcosm of a larger trend: Australia's datacenter boom. With an estimated $155 billion investment pipeline over the next decade, the country is experiencing a rush to build the infrastructure for the AI revolution.
The Datacenter Boom
The numbers are staggering: 160 datacenters currently operating, with another 90 proposed. These datacenters are key to the digital economy, housing servers and IT equipment that power websites, cloud services, and AI. But their impact goes beyond the digital realm, raising questions about power, water, and economic benefits.
Power and Water Concerns
The Mamre Road datacenter, if approved, will become Australia's single biggest energy consumer, surpassing even the Tomago aluminium smelter. This has prompted concerns from Penrith council and experts alike. The datacenter's energy consumption is expected to rise significantly, potentially reaching 10% of the east coast's electricity consumption by the mid-2030s. This raises the issue of sustainable and affordable power supply.
Datacenters also require vast amounts of water for cooling, and their proximity to residential areas has sparked opposition. The Climate Council estimates that without additional renewable energy sources, wholesale electricity prices could rise by 20% by 2035.
Economic Impact: Jobs and Productivity
While datacenters are not major job creators, they are seen by some as laying the foundation for the next wave of productivity growth. Pat Bustamante, a senior economist, believes this boom will be bigger than the PC and IT revolution of the late 90s. The real productivity boost, he argues, will come during the usage phase of the datacenters.
However, others are more cautious. Studies in the US show that while thousands of workers are needed during the construction phase, only hundreds are required once operational. This raises questions about the long-term economic benefits.
Broader Community Angst: AI and Datacenters
At the heart of the datacenter debate is a deeper community angst about AI. People are asking: Are we sowing the seeds of our own destruction by building these datacenters? Sally Auld, chief economist at NAB, captures this sentiment, reflecting on the unknowns of where AI will take us.
Optimism and Caution
Beth Webster, an economics professor, is optimistic that Australia can avoid the pitfalls seen overseas. She believes foreign direct investment brings knowledge exchange, a crucial aspect of economic growth. Pat Bustamante shares this optimism, seeing the datacenter boom as a foundation for future productivity.
However, Alex Hooper, head of climate and energy economics, urges caution. While there are huge opportunities, she argues, we need to be smart. Policymakers, she says, must develop an overarching industrial policy to ensure datacenters work for Australia, not just happen to it.
Conclusion: A Balancing Act
Australia's datacenter boom presents a complex challenge. While the potential for economic growth and productivity is significant, so too are the concerns about power, water, and job creation. As the country navigates this boom, it must strike a balance between embracing the opportunities and mitigating the risks. The datacenter debate is a microcosm of a larger conversation about the role of technology and AI in our future, and how we can ensure it works for us, not against us.
