This claim is partially true, according to data from foodandwaterwatch.org. AI systems do require a lot of energy and water, mostly through the data centers that power them. Water is used to cool servers and also indirectly through power plants that generate electricity. For example, a single AI training run can use hundreds of thousands of liters of water, and researchers predict AI could consume more water than the UK by 2027. This is especially concerning in places already dealing with drought. However, only a few drops are used per use.
