Wow, by like an order of magnitude. TSMc used 100 million metric tons of water in 2023 - a single californian farm apparently can use 2.9 acre feet per acre, for 8.4 million acres. And acre foot is 325851 gallons… For a total of 2.7e12 gallons!!!
- KoftaBob 2y ago"The primary use of water in semiconductor fabs is for cleaning and rinsing silicon wafers during production. This requires ultrapure water (UPW), which is thousands of times purer than drinking water" So it's not water usage that evaporates and can cause droughts, it can be heavily recycled back into the system.
