AbstractAbstract
[en] On 11 March 2011 Japan suffered an earthquake of very high magnitude, followed by a tsunami that left thousands dead in the Sendai region, the main consequence of which was a major nuclear disaster at the Fukushima power station. The accident ranked at the highest level of severity on the international scale of nuclear events, making it the biggest since Chernobyl in 1986. It is still impossible to gauge the precise scope of the consequences of the disaster, but it has clearly given rise to the most intense renewed debates on the nuclear issue. Futuribles echoes this in the 'Forum' feature of this summer issue which is entirely devoted to energy questions. Bernard Bigot, chief executive officer of the technological research organization CEA, looks back on the Fukushima disaster and what it changes (or does not change) so far as the use of nuclear power is concerned, particularly in France. After recalling the lessons of earlier nuclear disasters, which led to the development of the third generation of power stations, he reminds us of the currently uncontested need to free ourselves from dependence on fossil fuels, which admittedly involves increased use of renewables, but can scarcely be envisaged without nuclear power. Lastly, where the Fukushima disaster is concerned, Bernard Bigot shows how it was, in his view, predominantly the product of a management error, from which lessons must be drawn to improve the safety conditions of existing or projected power stations and enable the staff responsible to deliver the right response as quickly as possible when an accident occurs. In this context and given France's high level of dependence on nuclear power, the level of use of this energy source ought not to be reduced on account of the events of March 2011. (author)

AbstractAbstract
[en] The years go by and international conferences come and go, with their quota of cries of alarm and calls to action to counter climate change. But in reality few large-scale programmes have been launched anywhere in the world involving concrete action to bring down greenhouse gas emissions. As one who has campaigned for many years for policies of energy consumption control, Benjamin Dessus shows here that the energy challenge is as great as it has ever been in a world of expanding populations in which most peoples aspire to reach the developmental level of the northern countries, despite the fact that our climate probably cannot support such a state of affairs. He argues here against a certain number of common suppositions, such as the idea of focussing exclusively on CO2 in the fight against global warming, the need for a continuous economic growth on the order of 2% per annum or excessive faith in market mechanisms to bring down greenhouse gas emissions. He also stresses the ambiguities of so-called 'green' growth and compares different energy conservation scenarios. In this way, he shows that, against a relatively dominant line of reasoning based largely on (at times near-utopian) technological solutions and the continuation of sustained economic growth, there are more effective paths based on individual/collective energy sobriety and a serious slowdown of economic growth in the most developed countries, if not indeed a total halt to that growth (though these are more ambitious in that they require a revolution in the behaviour of the most affluent peoples). He concludes by proposing some courses of action for implementing such a programme in a country like France, showing the extent to which modern modes of life are going to have to change and how urgent it now is to debate these matters, if such change is to be achieved without - excessive - pain.

AbstractAbstract
[en] As Jean-Marie Chevalier stresses in this issue, it is currently quite tricky to pronounce on how energy prices will move over time or to predict how energy production systems will change. Further support for that view comes from this article by Rodolphe Greggio and Benoit Maffei. They have looked into the way long-term energy forecasts are made and their conclusion is that, as things stand, they are doomed to fail. The main underlying reason for this is the difficulty of making reliable predictions about how energy demand will evolve, since it is the product of exogenous developments that are unknowable in the long term (demographic growth, economic growth, productivity, energy efficiency etc.). A number of forecasting errors with regard to technological breaks have also played a role: a 'golden age' for natural gas was forecast too early; the date of 'peak oil' has shifted around wildly; a peak with regard to ore deposits has not had the impact originally anticipated; and the decline of nuclear power has turned out to require qualification. Ultimately, all this is the product of various political and geopolitical factors linked to the respective energy assets of the different countries and their strategies for achieving energy independence: e.g. the USA and shale gas, France and nuclear power, Germany and renewables. Quite clearly, the current context suggests that a gradual transition from carbon-based to renewable energies is the order of the day, but it is far from easy to predict on precisely what timescale, in what proportions and on what geographical scale this might occur.

AbstractAbstract
[en] As Jean Haentjens again stressed in our January-February 2020 issue, in the face of states' slow reactions, if not indeed inertia, in the battle against climate change, local tiers of government - and cities in particular - might well take charge and become 'powerhouses' for states by undertaking concrete initiatives. Francois Grosse argues along the same lines in this article in our second instalment in the series devoted to climate and energy questions. He argues for the rapid establishment of 'circular metropolises' in France, to transform the economy and modes of life as quickly as possible, so as to respond to the challenges posed by the target of keeping global warming below 2 deg. C to end of the century. After showing how massive and urgent these challenges are (and how, by failing to take account of indirect, imported emissions, they are largely underestimated in France) and how the French strategy fails to represent a coherent response, Francois Grosse shows that it has become essential to act at the level where it is possible to do so - i.e. where ail the actors can invest their intelligence and energies in an effective collaborative project. So it is at the level of metropolises and their immediate peripheries - going far beyond the 'sustainable city' notion that has emerged in recent decades - and by developing genuine circular metropolises, that it will be possible to achieve the objectives necessary for a genuine ecological transition, considered from ail angles, and thus radically transform the socio-economic system to make it compatible with our ecosystem.

AbstractAbstract
[en] Despite the alerts that have been sounded since 1992, as international conferences aimed at curbing global warming have come and gone, and despite the plans for reducing the use of fossil fuel resources that call for the moderation of energy consumption, few actions or incentive measures (and even fewer directives) have actually been developed to act on the demand for energy. Yet, as Henri-Luc Thibault and El Habib El Andaloussi show here, some very concrete measures can have major effects in this area. This is the case with everything relating to the improvement of energy efficiency in building, where housing conditions, the housing stock and related energy consumption (heating, air-conditioning etc.) are concerned. Thibault and El Andaloussi show the potential impact of such measures in the Mediterranean region. Basing themselves on the work of the 'Plan Bleu' organization, which has worked out a revolutionary scenario for the energy field in the countries of the southern and eastern Mediterranean (to 2030), they begin by recalling the importance of buildings in regional energy consumption and the various levers that might be used to reduce that consumption (regulation, materials, efficiency of machinery etc.). In such a scenario, the potential for energy savings in this sector would seem considerable. Moreover, this would enable a substantial decrease in greenhouse gas emissions to be achieved, and would also have very positive effects in terms of job creation. In conclusion, the authors point out the need for investment over 20 years, depending on the particular country concerned, to put in place the five flagship measures of energy saving, which would be genuine investments for the future..

AbstractAbstract
[en] The progress of science and technology has been so rapid in the last few decades that it receives especial attention in forecasting and foresight exercises. But, because they are too greatly in thrall to the dominant paradigms and hence favour a linear perspective, the experts who deal with these questions pay more attention to the future of technologies than to scientific advances and revolutions. The bulk of their work consists, then, in anticipating, by various different methods (Delphi surveys, Road-maps, etc.), at what date a particular technology might be available (without, however, always correctly gauging the conditions for its social appropriation or the applications to which it might be put). In this article, Pierre Papon expounds a much more original and promising approach for attempting to anticipate the discoveries that are likely radically to transform the fields of scientific knowledge by investigating the phenomena that may potentially lead to fundamental revolutions. After reminding us of the premonitory thinking of a number of authors - in the fields, for example, of genetics and computer science -, he endeavors to describe some of the dominant paradigms, particularly in quantum physics and molecular biology. In this way, he shows the advances they have made possible, and also their limitations, and explores what new scientific leaps forward might occur, bringing radically new technological breakthroughs between now and 2050. Papon reminds us, at the same time that, 'as science is not something isolated within society'; it has a duty to contribute to meeting the great challenges that face us - of work, health, nutrition and sustainable development, particularly where energy and climate are concerned. He therefore examines the ways in which future scientific and technological advances might provide solutions and how important it might be to 'translate the questions society poses into scientific questions'. He thus argues implicitly for strategic guidance of research, taking account of the challenges of the medium and long-term future, and, therefore, for a much closer dialogue between the sciences and society.

AbstractAbstract
[en] The autumn of 2010 has, in its turn, brought a trial of strength between anti-nuclear protestors and the authorities - in this case, over the train transporting 123 tons of nuclear waste between La Hague in France and Dannenberg in Germany. However, this episode, despite its spectacular nature and media impact, does not provide a true reflection of public opinion - and European opinion, in particular - with regard to nuclear power. As Pierre Bonnaure shows here, in the context of a progressive exhaustion of fossil fuels and the battle against climate change - which involves a reduction in greenhouse gas emissions - nuclear power may well recover its credibility. Public opinion seems less averse to it; states are developing new projects and ambitious nuclear programmes; and prospects in terms of resources (particularly, uranium) and technological developments seem set fair. After surveying the field and examining these various aspects, Pierre Bonnaure also reminds us of the remaining stumbling blocks: the question of radioactive waste, the lack of qualified labour in this sector and the funding difficulties. However, in these areas, it only needs states to make a substantial investment to consolidate an energy sector that has a bright future, provided it is assured of a technological research potential and safety conditions commensurate with the risks inherent in nuclear power.

AbstractAbstract
[en] Because of its effects on energy supplies, the Russian-Ukrainian conflict has speeded up efforts to develop renewable energy sources in Europe, thus indirectly contributing to the EU's ecological transition. However, to secure the implementation of that transition in this new context - and combine it with the digital transition, a second major axis of European policy - it is essential to develop a robust, long-term strategy. This is what is advocated in the EU's 2022 Strategic Foresight Report, the official presentation of which we carry in this issue. (authors)

Mais pour garantir la mise en oeuvre de cette transition, dans ce nouveau contexte, et la combiner a la transition numerique, deuxieme axe majeur de la politique europeenne, il importe de developper une strategie solide et de long terme. C'est ce que preconise le rapport de prospective strategique 2022 de la Commission europeenne, dont nous reprenons ici la presentation officielle. (auteurs)Original Title

AbstractAbstract
[en] In this article, the 'equilibre des energies' Association calls on the political authorities to implement a development strategy that is commensurate with the potential of Carbon Capture and Storage/Utilization (CCS/CCU) technologies, as a way of meeting the challenges of climate change. Steelmaking, chemicals, cement production, petroleum products, process heating and, indeed, the agri-food business are all industries which emit CO2 that can be captured and subsequently transported, stored and/or utilized, particularly in low-carbon synthetic fuels for air and sea transport.

En effet, la siderurgie, la chimie, la production de ciment, de produits petroliers, de chaleur industrielle ou encore l'agroalimentaire sont autant de filieres emettrices de CO2 susceptible d'etre capte pour etre ensuite transporte, stocke et / ou valorise, notamment dans des carburants de synthese bas-carbone a destination des secteurs aerien et maritime.

AbstractAbstract
[en] For several years now, global warming has occupied a leading place in the list of major challenges humanity has to confront and is, therefore, very logically the focus of regular international negotiations aimed at contributing to a solution. For the moment, however, the only international political responses envisaged for curbing climate change attack the identified cause of the problem - greenhouse gas emissions - with the intention of reducing the volume of those emissions in the shortest possible time-frame. However, as Baptiste Marsollat shows here, other, more technological responses exist which consist not in working on greenhouse gas emissions, but either in capturing/imprisoning these gases or, more ambitiously, in modifying solar radiation to reduce ongoing climate warming. This would mean applying the techniques of climate engineering or geo-engineering. Such a prospect has generated great controversy, but it cannot, for all that, be ignored indefinitely in the thinking on combating global warming. This article reviews the subject of climate engineering (what is it and to what extent can we do it?) and the role it might play in the battle against climate change. It shows how this - long-tabooed - option is now finding a place within the most official circles in the Anglo-Saxon world. Without concealing the concerns to which it may, more or less justifiably, give rise, Marsollat shows that, faced with a dramatic choice, we might opt in the end for climate engineering as a way to fight global warming. And from a more proactive perspective, he also suggests we should reflect on how appropriate it might be to use it for shaping the planet's climate and, in that way, for meeting a number of other major challenges.
