Perspectives énergétiques en Allemagne et en Europe : le point de vue d’un chercheur

Le mardi 9 décembre 2014, de 11h30 à 13h, l'ITIS et l'Institut EDS ont eu le plaisir de recevoir le professeur Joachim Knebel, chef de la division Génie mécanique et Génie électrique du Karlsruhe Institute of Technology (KIT). Il est venu présenter le point de vue d'un chercheur autour de la réforme énergétique de l’Allemagne - ou “Energiewende” - qui a générée des transformations majeures, pour l’ensemble du pays autant que pour l’Europe, et ce, dans tous les pans de la société.
Quels défis furent liés à sa mise en place et son développement? Quelles révolutions technologiques a-t-elle amorcée? Et quelles sont les prochaines étapes à franchir? Voilà autant de questions qui furent abordées lors de cette présentation.

Résumé de la conférence

Implementing the energy turnaround or ‘Energiewende’ - adopted by the federal government – has been a major transformation of the German energy system over the past two decades. It has also brought into sharp focus the challenges and the tensions that now continue to occupy researchers, politicians, businesses, and society facing the challenge of the century.

By 2050, Germany’s primary energy consumption is to be half of what it was in 2008. Renewable energies are to reach a share of at least 60 per cent of the country’s gross energy consumption and they are to cover 80 per cent of electricity consumption. Greenhouse gas emissions are to decrease by 80 per cent from 1990 levels. If Germany is to realise these goals, it has to restructure its energy system for the long term in a fundamental way. This requires new technologies for using primary energies and for converting, storing, and distributing them.
In line with the German Energy Research Programme, entitled ‘Research for an environmentally sound, reliable, and affordable energy supply’, and with the ‘New Hightech-Strategy – Innovations for Germany’, KIT performs national provident research in the six fields: (1) Energy Efficiency, Materials and Resources - for restructuring energy supplies; (2) Renewable Energies - for future-oriented energy supplies; (3) Storage Systems and Cross-linked Infrastructures - for the renewable energy age; (4) Technology, Innovation and Society - transformation processes and analyses of the energy system; (5) Nuclear Waste Management and Safety; and (6) Nuclear Fusion - as a long-term option.
Joachim Knebel will highlight the challenges and the promise of the German Energiewende both in a national and a European context and provide some successful examples and, in particular, how coordinated research results help to realise a new energy supply system, especially the integration of the fluctuating renewable energies. Finally, requirements and next steps are formulated which take into account the complex system context and the political and societal issues involved. 

Présentation du conférencier

Joachim Knebel is the Head of Division (BL3) at KIT. He is responsible for the two KIT Faculties Mechanical Engineering and Electrical Engineering with a total of 37 institutes, and the three Research Programs ‘Storage and Cross-linked Infrastructures’, ‘Fusion Research’ and ‘Nuclear Waste Disposal and Safety’.
Within the German Helmholtz Association of National Research Centres, he is Spokesperson for the Nuclear Waste Disposal and Safety Program and for the Cross-Program Activity on Electromobility. Joachim Knebel has a Ph.D. in mechanical engineering, he holds a Prof. h.c. from Saint Petersburg State University (SPbSU) and has authored or co-authored 160+ scientific publications and has given over 110 invited lectures at conferences, public hearings, press events, and specialist meetings world-wide.


In 2011, Joachim Knebel was awarded the European Science Culture Award of the European Foundation for Culture PRO EUROPA for merits in Partitioning & Transmutation Research.
