Erin Brockovich, known for a 1993 case over contaminated groundwater in Hinkley, California, says she is now targeting the expansion of data centers built to support artificial intelligence. Brockovich was instrumental in a lawsuit against Pacific Gas and Electric (PG&E) that led to a $333 million settlement for affected residents; she has since been associated with a widely known film portrayal. In recent weeks, Brockovich has received thousands of messages from people reporting concerns about nearby data centers. According to her account, she posted a callout on her website in April asking individuals with issues related to a data center to contact her, and within about a month she said 3,862 people responded. She characterizes the scale and long-term demand driving new facilities as unusually concerning, drawing a comparison to her earlier Hinkley experience. Brockovich is presented by outlets as launching a plan to challenge AI data center development, with her focus on alleged local impacts and public concerns.
