Do you know ChatGPT? It’s an artificial intelligence (AI) tool. It can answer questions, tell stories and write articles. But it’s very “thirsty”, said a new study from Harvard University.

ChatGPT has “homes” around the world in data centres (数据中心). When it works, the computers in the data centres get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away the pipes.

When you ask ChatGPT 50 questions, it “drinks” 500 millilitres (ml) of water. Scientists used about 700,000 litres of water to build ChatGPT. The water use is very big. People can make 370 cars with the water.

ChatGPT is just one of the AI tools around the world. You need data centres to do everything on the internet. There are more than 8,000 data centres around the world. The number is still growing.
