[en] This note proposes an analysis of political as well as economic causes of dysfunctions of electricity wholesale markets in Europe. The authors show that the market model is not adapted any longer to the present situation, and outline that these dysfunctions are due to the economic crisis, to the gas-coal merit order, and also, to some extent, to the development of renewable energies. Then, the authors state that a new equilibrium must be found between public intervention and markets, in a context where stakes related to security of supply, and industrial and land planning policies require specific objectives which cannot be reached only through an energy and CO_2 wholesale market play, but with public intervention. The authors then discuss the role of public authorities regarding the energy mix, and outline the necessity of a better prediction and definition of credible objectives for a better consistence of public policies, and the necessity of a translation of energy policy objectives into actual and flexible instruments. Some propositions are formulated, notably regarding the nuclear sector. In the last part, the authors propose some possible reforms for the electricity market by addressing different issues: long term contracts and short term optimisation of energy markets, and security of supply on the long term
[en] This paper outlines the necessity of giving new momentum to a coherent and comprehensive European energy policy. We initially outline the status quo and the recent initiatives from the European Council and Commission before calling for a more ambitious Energy Union with clearly defined policy proposals for action
[en] After a contribution which discusses the content of a report made by the author for the French Senate on the French-German cooperation in the field of energy as a possible element of emergence of a Europe of energy, a contributor recalls and comments the objectives of the German energy transition, and the issue of economic, environmental and social sustainability of this energy transition. The next contribution, proposed by a German researcher, notably comments two main aspects of the German energy policy, the so-called Energiewende, the phasing out of nuclear and the deployment of renewables, and discusses their consequences, results and political background. A fourth contribution discusses the relationship between Germans and energy: fear and enthusiasm in the 19. and 20. century, impact of the Chernobyl accident and other industrial accidents which resulted in the development of renewable energies (this is a background factor which explains that this issue remains present in the Energiewende). The fifth contribution, proposed by a member of a German think tank working on issues related to energy transition, discusses the Energiewende as an energy-related, industrial, and society-related project (technology, cost issue, challenge to make the electric system flexible, issue of CO2 emissions). The publication proposes a transcription of the debate on these different issues
[en] The thermal solar energy production is a promising and strongly growing sector. However, these technologies must be integrated to electric power systems, i.e. coupled with fossil-fired or biomass-fired plants, and the energy must be stored. This production can be either centralised or decentralised: this corresponds to different situations, different markets, different technologies and equipment (rows of mirrors to concentrate solar heat on a tube, linear Fresnel reflectors to concentrate solar heat on a tube, heliostats or mirrors which concentrate heat at the top of a tower, and parabolic disks which produce electricity with a Stirling gas engine at their focal point). This road-map focuses on electric power generation, and discusses key variables of the present market, proposes a vision for 2050, identifies objectives to be reached by 2015, and barriers to be removed, outlines the needs of demonstrators and their administrative framework.
