Data centres are booming in Australia - but at what cost?

Data centres have become a booming industry in Australia, despite concerns about their impact on local communities and the environment. People living near these massive structures often complain of the constant noise and humming that can be heard well over a kilometre away. As AI technology continues to grow in popularity, more data centres are being built to support it, with investors attracted to Australia's clean energy, natural gas reserves, and land availability.

One estimate suggests that over A$155 billion (£80 billion) of investment money is set to flow into the country's data centre sector.

However, the rapid expansion of these facilities has raised concerns about water supplies, energy use, and the environmental impact. Some experts argue that Australia may not have the capacity to meet the increased energy and water demands of new data centres, and that the boom could inadvertently lead to a rise in coal and gas power plants, resulting in higher power prices. There are also worries that data centres will rely on backup diesel generators during power outages, which could exacerbate environmental issues.

While the government sees the investment in data centres as crucial for the digital economy and job creation, environmental groups argue that the demand for renewable energy to power these facilities has not been adequately met. In the United States, some data centres have turned to building new gas-fired power stations due to the lack of sufficient renewable energy sources. This raises questions about whether Australia's data centre boom is sustainable and worth the potential environmental consequences.
