AI, i.e. deep learning, consumes huge amounts of energy because it has to train on gigantic amounts of data and the training algorithms are borderline efficient. So to stop using huge amounts of energy someone would have to come up with a way to get the same results without relying on deep learning. In other words all we need is a new technology revolution like the deep learning revolution, except one centered around a radically new approach that overcomes every limitation of deep learning. Now: how likely do you think this is to happen any time soon? Note that the industry and most of academia have bet the bank on deep learning partly because they think that prospect is extremely unlikely.
