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!!!
So it's not water usage that evaporates and can cause droughts, it can be heavily recycled back into the system.
