Data centres use large amounts of fresh water to cool servers on an industrial level scale.
The new apps make it easy for users to post videos they have created to social media, and has resulted in a deluge of videos on social feeds.
Earlier this month, Sora was downloaded more than a million times in less than five days – with the app still topping the Apple App Store charts in the US.
But Dr Grecksch warned that people should be “mindful” of the platforms environmental impact.
“There’s a lot of water involved and I think we just need to think about what we’re using it for, how we’re using it, and how often we’re using it,” he said.
He said the “cat was out of the sack” with regards to AI, but urged people to have “a little bit more integrated thinking around where we put data centres and how we are cooling them”.
“The government sees south Oxfordshire as one of the first AI growth areas, but that’s a massive problem because apparently no one has thought where the water is going to come from that’s going to cool down those servers.”
“There’s a lot of questions we need to think about.”
