The plenary lecture  considers important issues surrounding the energy consumption by Information and Communication Technologies (ICT) which has been steadily growing and is now attaining approximately 10% of the worldwide electricity consumption with a significant impact on greenhouse gas emissions. The perimeter of ICT systems is discussed, and the role of the sub-systems that compose ICT is considered. Data from recent years is used to consider how each of these subsystems contribute to ICT’s energy consumption.

About the Speaker:

Erol Gelenbe—Fellow IEEE’86, Fellow ACM’02, Fellow of the Royal Statistical Society, Honorary Fellow of the Islamic World Academy of Sciences, Fellow of the French National Academy of Technologies, the Royal Academy of Belgium, the Science Academies of Hungary, Poland and Turkey, and of Academia Europaea—is known for pioneering computer performance analysis, and inventing the Random Neural Network and its gradient and deep learning algorithms. Awarded the $500,000 Mustafa Prize for inventing Gelenbe-Networks that model both data networks and neural networks, he graduated 95 PhD students according to the American Mathematical Society Mathematics Genealogy Project.

Inventor of Cognitive Packet Network Internet routing using Reinforcement Learning to optimize multi-hop network paths, he received the ACM SIGMETRICS Life-Time Achievement Award in 2008 for pioneering research on computer and network performance. His papers appear in top journals of Electrical Engineering and Computer Science, including Proceedings IEEE, Journal ACM, Comm. ACM, IEEE Trans on Selected Areas of Communications, Computing Surveys, ACM/IEEE Trans on Bioinformatics, IEEE Trans on Neural Networks, IEEE Trans on Cloud Computing, Physical Reviews, Neural Computation, Neurocomputing, etc.
