The water used by artificial intelligence is expected to equal the needs of 1.3 billion people by 2030—threatening natural resources for billions around the world. That’s according to a new report from the United Nations University Institute for Water, Environment and Health (UNU-INWEH) which quantifies the carbon, water, and land footprints of AI's electricity use around the globe.  The report finds that AI’s environmental cost is often mismeasured—focusing solely on carbon emissions . However, cooling and generating power for data centers comes with a “water footprint,” while the energy infrastructure and supply chains to build the data centers have a “land footprint.” These are important factors to consider, the report says, when analyzing the stressors a region might be facing due to data centers .  By 2030, the report finds, global data centers powering artificial intelligence are projected to consume 945 terawatt-hours of electricity.…
