Australia is currently reviewing and developing mandatory standards for large data centers that affect the use of energy and water in these critical infrastructures. This decision comes in response to increasing concerns about the environmental impacts of large data center projects. Particularly with the rapid growth in demand following the boom in artificial intelligence, these infrastructures have become a central topic in political discussions.
Challenges in Data Center Data Collection
Data centers have traditionally existed for two decades, but recent changes in technology and demand have drawn more attention to these centers. Estimates indicate that in 2020, data centers consumed nearly 1.5 percent of the world's electricity, but with the growth of artificial intelligence, this figure has reached 3 percent in Australia and is projected to rise to 13 percent by 2030. This figure could place them alongside energy-intensive industries such as aluminum smelting.

However, accurate data on the water and energy consumption of these centers is not available. Approximately 225 data centers are in planning or development, and if all are approved, they will lead to new demand equivalent to 67 gigawatts of electricity. But this information is provided voluntarily by operators, making it difficult to compare and analyze.
New Measures and Their Implications
The Australian government is currently seeking to establish mandatory national standards for data centers that include the use of energy, water, and land. This legislation is set to be introduced early next year. This move could help improve transparency and assist in reducing local concerns regarding the environmental impacts of these centers.
For example, in Sydney, data centers currently consume about 3.5 billion liters of water annually, which is less than 1 percent of the city's water supply. However, this figure is expected to reach 25 percent in the next decade. This change could significantly impact environmental and social factors, especially in areas facing water shortages.
Many of these centers have been proposed in hot and dry regions, raising further concerns about water supply. Therefore, optimizing water and energy consumption in these centers must be prioritized. However, merely improving efficiency is not enough, and overall consumption of water and energy needs to be considered.
International experiences, especially in Ireland and the United States, show that the environmental impacts of data centers are primarily local, and host communities often oppose these centers due to issues related to noise, energy, and water. Therefore, creating transparency and collecting data can assist policymakers in making appropriate decisions.
Ultimately, the future of data centers in Australia heavily depends on the government's ability to manage demand and their environmental impacts. Establishing mandatory standards and collecting accurate data can help reduce tensions and local concerns and prevent negative environmental effects.
