Electricity supply is becoming the latest chokepoint to threaten the growth of artificial intelligence, according to leading tech industry chiefs, as power-hungry data centres add to the strain on grids around the world.

Billionaire Elon Musk said this month that while the development of AI had been “chip constrained” last year, the latest bottleneck to the cutting-edge technology was “electricity supply”. Those comments followed a warning by Amazon chief Andy Jassy this year that there was “not enough energy right now” to run new generative AI services.

Amazon, Microsoft and Google parent Alphabet are investing billions of dollars in computing infrastructure as they seek to build out their AI capabilities, including in data centres that typically take several years to plan and construct.
