South Bay data centers present environmental challenges
Numerous data center projects in Santa Clara County, California, are raising environmental concerns, particularly regarding water usage. A report highlights blind spots in environmental reviews and the lack of transparent water consumption data from operators. Residents are actively opposing these developments and demanding greater transparency and stricter regulations.
Santa Clara County's South Bay region, already the densest data center hub in California, faces growing environmental challenges due to over a dozen new data center projects. A report by Santa Clara University and Next 10 researchers reveals significant shortcomings in environmental reviews, especially concerning water usage amid a rapid AI-driven buildout. The study found that water providers and data center operators fail to disclose actual water consumption data, making it difficult to assess the true impact on local and state water systems.
Iris Stewart-Frey, an environmental science professor at Santa Clara University, emphasized the increased pressure on water planners to understand the implications of these developments, particularly with climate change and drought concerns. While Silicon Valley benefits from a relatively stable water supply compared to rural areas, the lack of transparency in water usage projections and cooling system details remains a critical issue.
Community opposition has emerged in San Jose, where residents, led by Ellina Yin, are demanding transparency, robust public engagement, cumulative environmental assessments, and enforceable protections for water use. Both San Jose and Santa Clara city officials affirm rigorous review processes, with San Jose requiring water assessments for data center projects. However, state lawmakers are now considering measures to strengthen oversight and reporting requirements for water usage, though the Silicon Valley Leadership Group's CEO Ahmad Thomas warns against over-regulation impacting innovation.
