Data centres tend to cluster together, often around cities. This can lead to bottlenecks in local grids.

They’re also growing in size. The largest data centre under construction will use 20X more electricity as a typical hyperscale data centre today 👉 iea.li/4j2r9P3

Thanks @davidajaeger.bsky.social and @scoteconsociety.bsky.social for organising another great conference!

Presented at #SES25 in Glasgow this week! My paper with Radek Stefanski explores the Environmental Kuznets Curve through the lens of structural transformation. Great conversations and insights on global energy transitions, thanks @scoteconsociety.bsky.social for having me!
