The chip industry uses as much water as the city of Hong Kong. Now factories are working to be more sustainable

• Semiconductor factories use millions of gallons of water daily.
• The more advanced the chip, the more processing and water are required.
• Chip fabs are developing ways to cut their footprint in response to regulation and water scarcity.

The boom in artificial intelligence is driving up chip demand, and the chip craze, in turn, is driving up demand for another resource: water.
