The public lecture series “Sustainability in Computer Science” will kick off on October 9, 2023.

Daniel Gruss, an Associate Professor in Information Security at the TU Graz, will give a talk on “Sustainable Security”.


Global ICT electricity consumption is already beyond 11 percent of the worldwide electricity production and still increasing. By 2030 it may reach around 25 percent. Previous approaches to improve efficiency and performance have often sacrificed security, leading to disastrous security issues like Meltdown and Spectre. Patching just these two vulnerabilities increases power consumption on affected computers by a seemingly harmless 5 percent. By 2030, this may be more than 1 percent of the global electricity production by just a single out of thousands of patches. This development is not sustainable, and in this talk, we will discuss both the problem and potential revolutionary solutions.


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.

Students from participating universities can register to get credits for the series. Please refer to your respective institution for registration.

TU Wien students can register for VU 194.155 “Sustainability in Computer Science” via TISS. Depending on your study program, the lecture series is a free elective or a “Wahlpflichtfach”, please refer to TISS for further information.
