Energy and AI (Technology Talk)

With increasing digitalisation, the electricity demand of servers and data centres is continuously rising across all companies – particularly due to data-intensive applications such as cloud services, streaming, AI applications and big data analytics. On November 5th, 2025, the NEFI Technology Talk “Energy Efficiency in Servers and Data Centres” organised by the OÖ Energiesparverband took place in Linz. The focus of the talk was on efficiency measures that help to reduce the electricity consumption of servers and data centres. The agenda included topics such as efficient cooling systems, energy management systems, optimal server utilisation and solutions for procuring new hardware. The event included presentations on current technologies and best practice examples, highlighted the impact of AI on energy consumption, and showcased how energy efficiency and operational reliability can go hand in hand. NEFI is the Austrian innovation network driving the transformation of industry towards climate neutrality. Its flagship projects demonstrate that climate-neutral industrial production is both technically and economically feasible through innovations “Made in Austria”. The NEFI Technology Talks are a series of events addressing current technical and systemic issues related to the industrial energy transition.
