[en] By letter dated 27 April 2011, the Director General of the Centre for Strategic Analysis, Vincent Chriqui, confided to Jean Bergougnoux, honorary president of the SNCF, Honorary General Director of EDF, the task of animating a reflection Prospective Technological Studies of the sectors of energy, transport and construction. This synthesis report, prepared with the assistance of rapporteurs Centre for Strategic Analysis, attempts to summarize and put into perspective all the work which show these specific reports. Admittedly some very complex issues still need supplements. It may therefore be useful to extend this work in a number of areas. Beyond its role in the competitiveness of a country, technological innovation is essential to provide appropriate responses to the challenges of our commitment to sustainable development in terms of economic growth, preservation of the environmental and social progress. Mission for Prospective Technological conducted by the Centre for Strategic Analysis has sought to clarify this dual problem by proposing a long-term vision for the energy, transport and construction. For each technology studied, it has attempted to assess both the possible contribution to sustainable development and the competitive potential of our country on the international scene. His work, chaired by Jean Bergougnoux have reviewed the technological advances that may occur in the coming decades in the sectors concerned. They examined the conditions for integration of these advances in systems and subsystems existing (or create) and the conditions of a mature technical, economic but also social. Wherever possible, two time horizons were identified: a medium-term horizon, 2030, for which we have a fairly clear vision of future developments and long-term horizon, 2050, which allows to consider jumps Scientists are still uncertain. Finally, the mission is interested in four transverse technologies involved consistently in the three study areas, which are likely to produce decisive progress (metrology, nano-technology, regulation and control command, the home network ). One of the lessons of the exercise is that technology foresight in France remains very crumbled, making it difficult both a systemic approach and yet essential, regarding the proper use of this scarce resource are public funds, prioritization on solid foundations. In each discipline in each sector, researchers, manufacturers have their own vision of the future, may be too optimistic for the first, but these visions fit poorly in a coherent framework to assess the real value of innovations possible. Set around a table specialists in different areas as we have done is both complex and constructive, but this exercise requires a prior rigorous methodological work to deepen and renew periodically knowledge. A practical difficulty in conducting a prospective overall is the lack of validated databases and shared the cost and performance of technologies. This applies both to the current state of various technologies for information - at least the orders of magnitude - about innovations in development or testing. These data exist or may exist, if the request was unclear, but they are scattered in many organizations and assume a coherence sufficient to serve as a basis for a prospective approach. The four proposals in the report: - Proposal No. 1: take into account the definition of mechanisms to support the development of technology, technical and economic maturity, their ability to integrate into existing systems and global positioning research and Industry French. - Proposal No. 2: In the area of electricity generation, encourage the deployment of renewable energy and competitive focus for those whose cost of electricity production would be above a threshold to be determined, and demonstration operations research. - Proposal No. 3: Given the price differences between the ground and photovoltaic roof, extend the concept of positive energy building a broader, island or district, to benefit local energy lower cost. - Proposal No. 4: Investing in the transverse technologies: control devices and systems management (and control) and in particular the building (home network) nano-technology; measurement techniques (metrology), the iCT; materials

[en] After a discussion of the evolution of the economic and demographic context, this report, illustrated by many data tables and graphs, proposes an analysis of demand evolutions in the building and urban sectors, in the transport and mobility sectors, in the food, agriculture and soil use sectors, and assesses the corresponding evolution of final energy consumptions. The second part analyses, discusses and assesses the various and important potentials of production of renewable energy: proposition of two variations for the de-carbonated energy mix, biomass mobilisation, directly used renewable energy sources, production mix of heat networks, the gas system. It then proposes a synthetic overview and discussion of the evolution of energy offer. The evolution of greenhouse gas emissions is then assessed and discussed. Lessons learned from this update are highlighted, and perspectives are discussed. A synthetic version of this report is also provided

[en] This large report contains contributions and contents of round tables and workshops held during a colloquium. Round tables addressed the following topics: challenges and perspectives for the law on energy transition and the electric mix, maturity and competitiveness of existing sectors, instruction manual for a decentralised electric mix, electric mix and grid adaptation. Workshop addressed wind energy (development status, key figures, participation-based wind energy, radar disturbances as a brake to wind energy development), photovoltaic workshop (development status and key figures, ADEME actions, project elaboration, governance, financing and self-consumption, R and D and industrial innovation, environmental impacts and recycling), geothermal energy (development status and key figures, Enhanced Geothermal System in Alsace, governance mode for projects in the French West Indies), and sea energies (development status and key figures, the PRISMER project, demonstrators, industrial fallouts of renewable sea energies, environmental impacts and acceptability). The second part of the reports contains all Power Point presentations
