Data centers are black boxes, but California wants to change that

THE NEWS

What happened

California Governor Gavin Newsom has signed new legislation requiring data centers to disclose their water and electricity usage, addressing growing public concerns about the infrastructure's impact on local resources and utility bills. The laws mandate monthly energy reporting and specific water disclosures during permitting, while also establishing separate power rates for these facilities to prevent cost-shifting to other consumers. Despite gaps in annual water tracking, the measures represent a significant step toward transparency regarding the environmental footprint of AI-driven data centers.

CONTEXT

Why it matters

California has moved to open the 'black box' of data centers with new disclosure laws signed by Gov. Newsom. Beginning next year, operators must report monthly energy usage and water consumption details. The legislation establishes separate power rates for these facilities to stop passing infrastructure costs to regular consumers and ensures they cover necessary grid upgrades. While annual water tracking remains limited until permit applications, the move signals strong regulatory attention to the environmental impact of AI infrastructure as it expands into rural communities.
