The Hidden Costs of Data Centers: Energy, Water, and Opacity

• The rapid growth of generative AI has led to an explosion in the number, size, and consumption of data centers, placing immense pressure on local resources.
• Corporate opacity, often justified by 'trade secrets,' makes it nearly impossible for the public to evaluate the true environmental and economic impact of these facilities.
• Critics and researchers are calling for moratoria on new construction and greater transparency to ensure the long-term sustainability of digital infrastructure.

Infrastructure Strain and Resource Consumption

• Modern hyperscale data centers, equipped with thousands of GPUs for AI, require significantly more power and water for cooling than previous generations.
• In regions like Aragon, Spain, massive investments by companies like AWS threaten to increase electricity demand by up to 15 times, potentially turning the region into a net energy importer by 2031.
• The International Energy Agency (IEA) projects global data center electricity consumption will reach 945 terawatt-hours by 2030, equivalent to Japan's total annual consumption.

Economic and Transparency Challenges

• While touted as engines of economic growth, the long-term local employment impact is often minimal. Research from Brazil suggests up to 85% of investment in such facilities is spent on imported hardware rather than local goods or services.
• Major tech firms have successfully lobbied for secrecy clauses in EU legislation that block public access to data regarding environmental impacts.
• Experts note that without clear, public metrics on water and energy use, local governments often approve massive projects without understanding the long-term consequences.

Calls for Public Debate and Regulation

• Civil society efforts in countries like Uruguay have successfully challenged commercial secrecy, forcing the disclosure of water consumption data which then became a focal point for public policy debates.
• At least 14 U.S. states have introduced legislation to regulate or curb the expansion of hyperscale facilities due to concerns over grid stability and sustainability.
• Researchers and activists advocate for a pause in construction to allow for participatory, transparent evaluations of how digital infrastructure aligns with local territorial and resource needs.
