On the eve of the US midterm elections, at least seven cities in California's Bay Area passed moratoriums on data center construction. Although the region is an artificial intelligence (AI) hub, local residents have expressed concerns about the strain on the energy grid, high electricity bills, and water consumption caused by the rapid expansion of data centers. Cities such as San Francisco and Oakland have implemented temporary bans, and local politicians have used this as a campaign issue. For example, San Francisco Supervisor Connie Chan supports a nationwide ban, while State Senator Scott Wiener opposes it.
