As our lives become increasingly digital, the infrastructure powering them is sparking a global debate: we need data centres, but at what cost to the climate and our access to energy? These massive facilities are the backbone of everything from streaming to AI, yet they consume staggering amounts of electricity and water, often straining local grids and and in some cases, threatening to derail decarbonisation efforts.

In this episode of Cities 1.5, we explore how Ireland became the "canary in the coalmine" for this issue. With data centres projected to consume nearly 30% of the nation’s electricity by 2030, the Irish experience serves as a critical warning – and a roadmap – for cities worldwide. We examine the tension between economic ambition and climate mandates, questioning how urban leaders can manage the rapid expansion of digital infrastructure without derailing net-zero goals. Join us as we dive into the lessons learned from the frontlines of the data centre boom and what they mean for the future of sustainable cities.
