Ketan Joshi

So I reached out to an expert on data centres and their energy use to go through some of the numbers.

My name is Ketan Joshi.

I'm an independent researcher and analyst working on energy and data centres and fossil fuel phase-out.

Ketan has been working as an energy analyst for many years, but more recently has been focusing on how much energy data centres consume, particularly for artificial intelligence.

But I think having very good, affordable substitutes for people to switch to is just really, really crucial.

This episode was written and produced by me, Nick Petrichow.

Dan Fox was my editor, and thanks to Hannah Ritchie, Ketan Joshi, and Nicholas Herner for speaking to me for this episode.

As it happens, I know a guy.

Ketan Joshi spent years in the Australian wind industry fending off bogus health scares about turbines.

These days, he's a freelance writer and analyst, producing the most thorough critiques I've seen of big tech's climate claims, taking aim at everything from Google's exploding electricity use to NVIDIA's undisclosed emissions to the idea that AI will solve climate change.

I'm excited to ask him whether data centers can ever be good grid citizens, why so much of climate tech has quietly dropped the climate part, when the rush to gas will end, and how big this bubble really is.

So let's get into it.

With no further ado, Ketan Joshi, welcome to

Volts.

Thank you so much for coming.
