The global expansion of data centers is prompting governments to consider stricter rules for electricity use, water consumption and environmental disclosure. Reuters reports that European policymakers are considering transparency and efficiency measures, while some Australian jurisdictions are attaching renewable-energy and water requirements to new facilities. Operators are experimenting with cooling systems and recycled water, but rapid demand for computing capacity continues to test local infrastructure. The business question is no longer only where companies can secure land and power. Communities increasingly want evidence that new facilities will not shift utility costs or resource shortages onto households. The regulatory approaches differ, creating incentives for developers to choose jurisdictions with less demanding standards. Reuters surveyed the emerging policy approaches.
