San Francisco Supervisors Propose Data Center Moratorium; Santa Clara Continues Expansion

Santa Clara, California, a hub for major tech companies like Nvidia, Intel, and AMD, is actively embracing data center expansion, investing $459 million to double its power grid capacity to accommodate more facilities. The city currently hosts 58 data centers, the densest cluster on the West Coast, primarily located within its limits and neighboring Mountain View. Residents benefit from lower electricity rates provided by Silicon Valley Power, a city-owned utility, and the city collects an estimated $29.5 million annually from server farms, which funds public services.

Conversely, San Francisco County, with 15 existing data centers, is facing a proposed 45-day moratorium on new data center developments. Supervisor Shamann Walton introduced the measure, citing concerns about the environmental burden on neighborhoods like Bayview, which has a history of pollution. The article contrasts San Francisco's high population density, which places homes close to potential data center sites, with Santa Clara's broader industrial belt. The differing approaches highlight the complex interplay of economic benefits, environmental impacts, and community concerns.

Concerns about data center impacts, including electricity consumption and water use, are discussed. Jonathan Koomey, a researcher, notes that smaller, well-managed data centers may have minimal impact. Valley Water stated that most Santa Clara data centers use recycled wastewater for cooling, minimizing their water footprint. Intel is funding the expansion of a local substation for Santa Clara's data centers, along with additional fees, demonstrating how developers are expected to cover infrastructure costs. Despite the benefits, some Santa Clara residents have voiced complaints about noise, height, and appearance of facilities, while others monitor environmental impacts on local wildlife.
