On December 18, 2023, the public lecture series “Sustainability in Computer Science” carries on with a new topic.

René Mayrhofer, head of the Institute for Networks and Security at the Johannes Kepler University Linz, will give a talk on “Computer Science Between Energy Savings and Waste: From Videoconferencing to Blockchain”.


Digital information and communication services offer the potential for significant energy savings: video conferencing instead of trans-continental flight, file transfer and streaming instead of shipping physical media, or cryptocurrency instead of transporting gold and paper money. But what is the real energy balance of these digital options? In this talk, we try to quantify such comparisons based on estimates of the energy consumption of various digital services.


About Lecture Series “Sustainability in Computer Science”

The Public Lecture Series is the first of its kind in Austria, with all Austrian computer science departments and faculties participating, under the auspices of Informatik Austria. We want to raise awareness for the utmost importance of sustainability in CS, demonstrating research solutions to various problems, and triggering developments for a sustainable future.

The lecture series will be held online every Monday from 17:00-18:00. One hybrid session takes place on January 8, 2024, on-site at TU Wien and online.
