In Silicon Valley, residents and environmental groups are organizing against proposed data center projects that the city of San Jose is trying to attract as part of its strategy to become a hub for AI infrastructure. The city estimates each new facility could generate between $3 million and $6 million annually in tax income but faces resistance from locals concerned about electricity use, water consumption, pollution, and overall impact on quality of life. Mayor Matt Mahan acknowledges residents' concerns while advocating for responsible development rather than halting it entirely. California Governor Gavin Newsom is considering new legislation to address the costs associated with powering data centers and increase transparency regarding their energy and water usage.

Story summary
In Silicon Valley, residents and environmental groups are opposing a surge of proposed AI data center projects in San Jose, California. The city, with nearly 1 million people, is trying to position itself as an AI infrastructure hub by supporting these developments. However, local opposition has risen due to concerns about the high electricity usage, water consumption, and pollution associated with such facilities.
The PG&E utility company has partnered with San Jose in 2025 to expedite power delivery to large energy users like data centers. Despite the controversy, city officials estimate that each new facility could bring in between US$3 million and US$6 million annually in tax revenue for essential services such as police, fire protection, libraries, roads, and parks. This scenario reflects a broader national dilemma: how to balance economic competitiveness with public concerns over environmental impacts.

asserted
it → say → development
“People are right to question, ‘Is this pushing up my energy costs?
asserted
this → question → costs
Is it using our clean water supplies? Will it degrade quality of life in my city?’” Mahan told Reuters.

The fight comes as California Governor Gavin Newsom weighs a package of Bills intended to protect state residents from the costs of powering data centres and increase transparency around their energy and water use.
asserted
Newsom → come → use
PG&E said new large customers can help spread fixed grid costs across a broader customer base and help lower bills.
asserted
customers → say → bills
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 at data centres, arguing that existing regulations predate the recent expansion of AI-related facilities.

New legislation pending
The concerns raised in San Jose have increasingly made their way to Sacramento, California’s capital.

Lawmakers recently gave final approval in both the state Senate and Assembly to several Bills addressing data centres, including measures intended to ensure large electricity users pay their share of grid-related costs and requirements aimed at increasing transparency around energy and water consumption.
asserted
users → give → consumption
State Senator Steve Padilla, who authored several of the measures, said California has an obligation to lead because it is home to many of the world’s largest technology companies.
asserted
it → author → companies
The Data Center Coalition, an industry trade group whose members include Google, Meta, OpenAI and Anthropic, said it supports responsible growth but argued the Bills unfairly single out data centres rather than other large industrial and commercial electricity users.
asserted
Bills → include → users
The group warned the measures could discourage investment and push jobs, tax revenue and projects to other states.
uncertain
measures → warn → states
Newsom has until the end of September to either sign or veto the legislation.
