Sam Altman, the chief executive of ChatGPT creator OpenAI, has defended the vast use of energy by artificial intelligence by comparing it with the food eaten by humans.
AI systems such as ChatGPT use large amounts of energy, both when they are trained and then when they are used to answer queries. The heavy energy use of such systems has been recognised by people including Mr Altman himself, who has suggested that the world needs to adopt new technologies such as solar power and nuclear fusion to power AI in more clean ways.
