The European Central Bank published an ECB Blog post on the interaction between artificial intelligence and the green transition, arguing that the two are not necessarily on a collision course even though both increase electricity demand. The post frames the main issue as a shared set of structural constraints that, if addressed, could allow AI-driven productivity gains while supporting decarbonisation. To illustrate the energy challenge, the post cites Eurosystem research comparing electricity use for digital services, including around 0.3Wh for a standard Google search versus roughly ten times that for a ChatGPT request, and 7-9Wh for an AI-augmented Google search. It notes that data centres already represented around 21% of Ireland’s total electricity use in 2023 and are expected to contribute to higher EU electricity demand, alongside other drivers such as an additional 9 million battery electric vehicles and 11 million new heat pumps. The post highlights authorisation delays and grid-connection queues as bottlenecks affecting both renewables expansion and data-centre buildout, citing International Energy Agency estimates that connecting already grid-cleared wind and solar projects would raise Italy’s end-2022 capacity by 45% and triple Spain’s. It also points to AI-enabled efficiency gains, including wind site modelling accelerated by up to a factor of 4,000, a 40% reduction in data-centre cooling energy using DeepMind at Google, and a Swedish trial cutting energy use in two apartment buildings by 20%. On financing and capacity constraints, it cites estimated additional green-transition investment needs of 2.7% to 3.7% of EU GDP annually until 2030 and an identified AI investment gap of around EUR 5-10 billion per year, alongside governance, competition, market flexibility and skills as cross-cutting enablers. The post is part of an ECB Blog miniseries linked to the ECB conference “The Transformative Power of AI” on 1-2 April 2025 and reflects the author’s views rather than the official views of the European Central Bank and the Eurosystem.

European Central Bank blog examines how AI could support the green transition despite rising electricity demand
The European Central Bank published a blog post on AI and the green transition, emphasizing coexistence despite increased electricity demand. It identifies structural constraints that, if addressed, could enable AI-driven productivity gains while supporting decarbonization, highlighting energy challenges and investment needs. Part of a miniseries linked to the ECB conference "The Transformative Power of AI," it reflects the author's views, not the official stance of the ECB or Eurosystem.
