How much does your own AI use matter? With all the warnings about AI’s adverse impact on the environment, it can be tough to understand what that means at the individual level. In this episode, Morgan breaks down the hidden costs of generative AI into something more relatable: microwave time. She’s joined by MIT Technology Review reporters Casey Crownhart and James O’Donnell, who spent months investigating how much energy and water AI systems actually use.

Together, they unpack how AI models are trained and which ones are more resource-intensive, what effect the expansion of AI data centers has on local energy grids and just how much electricity it takes when we ask AI to generate text, images and videos.

Guests:

Casey Crownhart, senior climate reporter at MIT Technology Review

James O'Donnell, senior AI reporter at MIT Technology Review
