By 2030, water consumption linked to the use of artificial intelligence will be equivalent to that of 1.3 billion people in sub-Saharan Africa, while it will require nearly three times the annual energy consumption of Pakistan, Bangladesh and Nigeria — countries with a combined population of 650 million.
