The UK needs more nuclear energy to power the data centres needed for artificial intelligence (AI), the boss of the world's largest cloud computing company has said.

Amazon Web Services (AWS), which is part of the retail giant Amazon, plans to spend £8bn on new data centres in the UK over the next four years.

A data centre is a warehouse filled with computers that remotely power services such as AI, data processing, and streaming, but a single one can use the same amount of energy as a small town.

Matt Garman, chief executive of AWS, told the BBC nuclear is a "great solution" to data centres' energy needs as "an excellent source of zero carbon, 24/7 power".

AWS is the single largest corporate buyer of renewable energy in the world and has funded more than 40 renewable solar and wind farm projects in the UK.

The UK's 500 data centres currently consume 2.5% of all electricity in the UK, while Ireland's 80 hoover up 21% of the country's total power, with those numbers projected to hit 6% and 30% respectively by 2030.

The body that runs the UK's power grid estimates that by 2050 data centres alone will use nearly as much energy as all industrial users consume today.

In an exclusive interview with the BBC, Matt Garman said that future energy needs were central to AWS planning process.

"It's something we plan many years out," he said.

"We invest ahead. I think the world is going to have to build new technologies. I believe nuclear is a big part of that particularly as we look 10 years out."
