AI Datacenters in the U.S. Raise Concerns Over Water Use Amid Drought
• The U.S. is experiencing a significant expansion of artificial intelligence (AI) datacenters, with two-thirds of planned facilities set to be built in drought-affected regions, according to The Guardian. These datacenters, which require substantial water for cooling, are projected to consume up to 73 billion gallons annually by 2028, a sharp increase from 17 billion gallons in
• The facilities, often located in arid areas due to lower land costs and tax incentives, are adding pressure to already strained water resources. For example, a recently approved datacenter in Utah, twice the size of Manhattan, has sparked local opposition due to its potential impact on the Great Salt Lake. While the industry is adopting water-saving technologies like closed-loop cooling, these systems often require more energy, further complicating environmental concerns. Experts warn that the growing demand for water by datacenters could exacerbate existing shortages, particularly in regions already grappling with climate-induced droughts.
Why It's Important?
The rapid expansion of AI datacenters poses significant risks to water resources in drought-prone areas. Large facilities can use up to 5 million gallons of water daily, equivalent to the needs of 50,000 people. This increased demand could strain aquifers and river systems, particularly in arid regions like Utah, Texas, and Washington. Local communities, including farmers and ranchers, are concerned about the competition for limited water supplies, which could lead to higher costs and reduced availability for agriculture and residential use. Additionally, the reliance on energy-intensive cooling systems may contribute to higher greenhouse gas emissions, further exacerbating climate change and its associated impacts on water availability.
