Silicon Valley’s push to expand artificial intelligence infrastructure is facing growing resistance from residents and environmental groups concerned about the electricity, water and pollution impacts of new data centers.
San Jose, California’s third-largest city with nearly a million residents, has actively sought data center development as part of its effort to establish itself as a hub for AI infrastructure. But community groups are demanding greater scrutiny of proposed projects and questioning whether the economic benefits will be broadly shared.
The debate reflects a broader challenge for communities across the United States as governments seek to accommodate an AI industry that requires increasingly large amounts of computing infrastructure while addressing concerns about energy demand and environmental effects. California is at the center of that debate because it is home to major AI and technology companies including Google, Meta, OpenAI and Anthropic.
San Jose weighs AI growth against local concerns
San Jose officials have promoted data center development partly because of the tax revenue the facilities can generate. The city estimates that each new data center could provide between $3 million and $6 million in annual tax revenue, helping fund services including police and fire protection, libraries, roads and parks.
The city also announced an agreement with utility PG&E last year intended to speed electricity delivery to large energy users such as data centers. However, residents and environmental advocates say the economic benefits need to be weighed against the infrastructure and environmental demands of the facilities.
Ellina Yin, a leader of the grassroots I Love San Jose coalition, said residents want companies to demonstrate how their projects would benefit the community. Community groups are calling for stricter public review, greater transparency around energy and water consumption and studies examining potential health and environmental effects before additional projects are approved.
San Jose Mayor Matt Mahan has said the city should not halt data center development but should ensure that projects are developed responsibly. “People are right to question, ‘Is this pushing up my energy costs? Is it using our clean water supplies? Will it degrade quality of life in my city?’” Mahan told Reuters. “These are very fair questions.”
Electricity and pollution concerns
Electricity demand is among the central concerns as AI data centers require large amounts of power to operate and support advanced computing systems.
California lawmakers have approved several measures addressing data center development, including proposals designed to ensure that large electricity users pay their share of grid-related costs and requirements for greater transparency around energy and water consumption.
PG&E has argued that adding large customers could help distribute fixed grid costs across a broader customer base and potentially lower electricity bills. Air pollution is another issue.
In April, a coalition led by the Center for Biological Diversity petitioned the Bay Area Air Quality Management District to strengthen oversight of diesel backup generators used by data centers. The coalition argued that existing regulations were developed before the recent expansion of AI-related facilities.
The air district said it was examining whether stronger protections were warranted.
California considers new data center rules
The local debate has expanded into California’s state government, where lawmakers have given final approval to several bills addressing data center energy use and transparency.
State Senator Steve Padilla, who authored several of the measures, said California has an obligation to lead on the issue because it is home to some of the world’s largest technology companies.
The Data Center Coalition, an industry trade group whose members include Google, Meta, OpenAI and Anthropic, supports what it describes as responsible growth but argues that the proposed rules unfairly target data centers rather than other large industrial and commercial electricity users.
The group has warned that the measures could discourage investment and shift jobs, tax revenue and data center projects to other states. California Gov. Gavin Newsom has until the end of September to sign or veto the legislation. His office declined to comment to Reuters because the bills remain pending before the governor.
AI infrastructure expansion faces new scrutiny
The San Jose debate illustrates the growing tension surrounding the physical infrastructure behind the AI boom.
Technology companies and government officials have promoted data centers as important infrastructure for expanding AI capabilities and supporting economic activity. At the same time, communities hosting the facilities are increasingly asking how the electricity, water, environmental and infrastructure costs will be distributed.
For Silicon Valley, the discussion is particularly significant as San Jose seeks to attract additional AI infrastructure while residents and environmental groups push for greater transparency and public oversight.
