Data centre debate heats up ahead of US midterms - here's what you need to know
The BBC examines the rapid growth of data centers and the rising backlash over their electricity use, water consumption, emissions, noise and land requirements. In the United States, opposition has become a significant political issue ahead of the midterm elections, while President Donald Trump and industry supporters defend data center expansion.
Data centers are expanding rapidly, particularly in the United States, which has the world’s largest concentration and capacity of facilities. Their growth is being driven by cloud computing and artificial intelligence, with projects such as xAI’s Colossus 2 using large numbers of Nvidia chips and gas turbines to power AI workloads.
The expansion is generating concern over electricity demand, pressure on power grids, water consumption, emissions, air pollution and noise. The BBC reports that 16 U.S. states have proposed measures to ban or temporarily block new facilities, making data centers a potential issue in the midterm elections. Supporters, including President Donald Trump and technology companies, argue that the facilities strengthen national security, support AI development and create jobs and tax revenue.
