Is AI a major drain on the worlds energy supply? [Video]

When Google announced this week that its climate emissions had risen by 48 percent since 2019, it pointed the finger at artificial intelligence.

US tech firms are building vast networks of data centres across the globe and say AI is fuelling the growth, throwing the spotlight on the amount of energy the technology is sucking up and its impact on the environment.
