Illinois and California are developing policies that require data centers to account for their electricity demand, grid costs, water use, emissions, and community impacts.
Measures include dedicated electricity tariffs, clean-energy procurement, water reporting and cooling standards, environmental review, ratepayer protections, and stronger siting authority. The broader direction is toward making large computing projects bear more of the infrastructure and environmental costs associated with their expansion, although several measures remain proposed or await implementation.
