San Jose AI Data Center Boom Faces Local Resistance
San Jose wants more data centers because they help run artificial-intelligence services and could bring in tax money.
Data centers are large buildings filled with computers.
Residents worry they may use too much electricity and water.
They also fear pollution from diesel generators and possible effects on health and quality of life.
Community groups want more information and stronger public reviews before projects are approved.
Mayor Matt Mahan supports development but says it must be responsible.
California lawmakers approved rules requiring large electricity users to help pay grid costs and disclose resource use.
The data-center industry says the rules could unfairly hurt its businesses.
Governor Gavin Newsom must decide whether to sign or veto the bills by the end of the month.
San Jose officials are courting data centers to establish the city as an AI infrastructure hub.
Residents and environmental groups want stricter reviews of projects’ electricity, water, pollution and health impacts.
The city estimates each new facility could generate $3 million to $6 million in annual tax revenue.
California lawmakers approved bills requiring large electricity users to pay grid costs and disclose energy and water use.
The Data Center Coalition says the measures unfairly target data centers and could drive investment and jobs elsewhere.
