Europe and its Energy Objectives

Chiming in with the central theme of this summer issue, in this article Jean-François Drevet provides a presentation of the main aims of EU policy in the field of energy. After reminding us that there is, strictly speaking, no common energy policy in Europe, he outlines the four major challenges confronting the Union in this area: energy savings, the production of renewable energy (with the declared aim of covering 20% of final consumption from renewable sources by 2020), the reduction of greenhouse gas emissions (for which the declared targets are particularly ambitious) and, lastly, problems of energy security (particularly, the question of energy supplies to those countries most dependent on external provision). In all these fields it is, once again, the strength of a united community that can make the difference, though this presents another substantial challenge, given the increasing distrust of consumers, who tend to ascribe recent energy price increases to market liberalization brought about in recent years under the aegis of the EU.

La voiture électrique n’est pas née, vive la voiture hybride !

En dépit des investissements et des effets d’annonce toujours plus nombreux des constructeurs et des pouvoirs publics, la « révolution » de la voiture électrique n’a toujours pas eu lieu en France. Peut-être parce que ces véhicules représentent toujours un surcoût important par rapport aux voitures thermiques, qui pourrait perdurer au cours des 10 prochaines années. C’est la conclusion d’un récent rapport du Commissariat général au développement durable (CGDD), qui invite aussi à reconsidérer le potentiel des véhicules ...

Comportements : les nudges verts, la solution ?

En matière de comportements respectueux de l’environnement, des écarts parfois importants demeurent entre les intentions déclarées et les actions des ménages, même si des améliorations sont observées depuis quelques années . Pour modifier leurs comportements, les ménages ont-ils besoin de petits « coups de pouce » ? C’est en tout cas le principe sur lequel reposent les nudges verts, qui permettent d’orienter les décisions sans les contraindre.

Quel avenir pour le solaire photovoltaïque ?

Les énergies renouvelables (EnR) sont-elles incontournables ? se demandait récemment Pierre Papon , qui constate que l’Agence internationale de l’énergie n’envisage pas de scénario énergétique mondial sans recours à ces énergies à l’horizon des 15 prochaines années. Si le développement des EnR s’est accéléré dans le monde en 2010, les baisses de subventions publiques annoncées en 2011, notamment pour le solaire photovoltaïque, pourraient les rendre moins attractives, au moins pour les particuliers.

Shaping the Planetary Climate? The Prospects for Climate Engineering

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.

Energy and Climate Scenarios: Before and After Copenhagen

Following on from his contribution to the special number “Energy Prospects and Greenhouse Effect” (Futuribles 315, January 2006), which gave an account of the main foresight scenarios played out on the stabilization of greenhouse gas emissions, Patrick Criqui (with Constantin Ilasca) shows here how scenarios in this area have evolved since 2007. Though the long-favoured approach consisted in starting out from global targets for the reduction of greenhouse gas emissions, set at international conferences, and building national policy scenarios around them (the so-called “top-down” approach), the rapid economic growth of the emerging countries (particularly China) and the return of the USA to international climate change negotiations have altered the state of play. Since the Copenhagen Agreement of late 2009, it would seem, then, more logical, argue Patrick Criqui and Constantin Ilasca, to start from policies and targets set out at the national level in developing scenarios on global climate change (the so-called “bottom-up” approach).

Criqui and Ilasca lay out this paradigm change in detail. For example, they present the forward view of greenhouse gas emissions as it looked before Copenhagen, based mainly on assessments of the costs associated with the mitigation policies required to limit climate warming. They then analyse various so-called “post-carbon” transitional scenarios (which are supposed to sound the death-knell of the era of massive CO2 emissions), combining climate policy, energy sustainability and modes of economic development. Lastly, they show the turnabout that has been developing since the Copenhagen Agreement and the now manifest tension between ambitious global objectives (limiting global warming to 2°C up to 2100) and national realities leading to more limited commitments (particularly in the emerging economies) – a new context which might give rise to new families of scenarios, incorporating this sacrificing of global well-being on the altar of (sadly, less sustainable) national prosperity.

Climate Change after Cancún: An Agreement on Principles, but lacking Levers of Change

Climate change and its potentially serious consequences for our planet first appeared on the agenda of major international negotiations at the Rio Summit in 1992. Arduous negotiation ensued, culminating in the Kyoto Protocol in 1997, which set quantified targets for the reduction of greenhouse gas emissions to 2012. Since then, the configuration of the highly complex negotiations (on account of the large number of participants and disparity of economic situations) has changed a great deal, as could be seen at the Copenhagen conference of December 2009 and, more recently, the agreement struck at Cancún in late 2010.

Anaïs Delbosc and Christian de Perthuis, close observers of climate-related economic issues, sum up the state of international climate negotiation in this article. Where have we got to? How have the discussions developed? What are the points of agreement and disagreement? What economic mechanisms have been put in place and so on? After reviewing the history, Delbosc and de Perthuis outline the Cancún agreement, before looking in more detail at a “variable geometry system of commitment”. They show, in particular, how difficult it is to compare the commitments made by the various parties to the negotiations. However, they do stress that the developed countries are, in general, falling short of the recommendations of the Intergovernmental Panel on Climate Change. They go on to formulate a number of proposals designed to take the commitment to reducing greenhouse gas emissions further, for example by strengthening and unifying the system of measurement and verification of how the various countries are meeting the targets to which they have committed themselves, while nonetheless taking account of their varying situations. Lastly, they propose a more efficient use of the various existing economic instruments, and go on to remind us of the weaknesses that were not resolved by the Cancún agreement, which the Durban Conference, scheduled for late 2011, will have to strive to overcome.

La possibilité d’exploiter le gaz de schiste, comme le font déjà les États-Unis, a suscité un engouement pour cette ressource énergétique ainsi qu’une floraison de rapports pour en évaluer les perspectives.

A New Economic and Political State of Play in the Energy Sector: On Jean-Pierre Hansen and Jacques Percebois, Énergie. Économie et politiques

If there is one sector in which the state of play has changed radically over a few decades, it is the energy sector. It has been affected simultaneously by the prospect that the main fossil fuels will become exhausted, by the impact on our planet’s climate of the consumption of this fossil energy (implying increased recourse to renewable sources) and by the rapid economic development of large nations consuming increasing quantities of energy. Energy-related policies (particularly economic and technological policies) are, in fact, being developed in an increasingly complex and international context, which is, at times, very difficult to grasp.

Fortunately, two specialists in energy matters, Jean-Pierre Hansen and Jacques Percebois, have published a very comprehensive survey of this new economic and political state of play in the energy field: Énergie. Économie et politiques [Energy: Economics and Policies] (Brussels: De Boeck, 2010). It clearly isn’t possible here to go into all the questions they confront, but in this review Jacques Lesourne, who has read the book for Futuribles, clearly demonstrates its importance and presents the reader with the main facets of the work that make it a reference tool for all involved in this sector, including the most highly specialized.

Green Growth – an Illusion? Energy and Climate Risk: Rethinking our Developmental Models

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 conservancy 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.

Prospects for Oil and Gas

It was five years ago, in January 2006, that Futuribles devoted a major special issue (no. 315) to energy prospects and the greenhouse effect. That was already a time of great concern about this question and several articles offered analyses of the gloomy prospects for the development of energy resources and the issues around climate change. Among these, an article by Jean Laherrère outlined the prospects for oil resources, showing the extent to which information in this area was disparate, unreliable and even questionable, being often highly political. As one of the more pessimistic writers on the question, Laherrère reminded us of the imminence of “peak oil” (the prelude to a decline in global oil production) and the need to re-think our styles of consumption to adapt to a new age in which, as energy becomes scarcer, it will be increasingly expensive.

Five years later, Jean Laherrère returns to the columns of Futuribles on the occasion of a new special issue on energy and the climate, to update us on the global prospects for oil and gas production. He begins by recalling how politically slanted and unreliable information in this area can be, depending on its source, the units of measurement employed etc. He stresses, too, that in the view of many experts peak oil was reached in 2006 and the situation is currently plateauing, just ahead of a decline in oil production (gradual or sudden, depending on whether measures of economic constraint are implemented). For its part, gas production should peak around 2025-2030. Jean Laherrère specifies what reserves remain, how these are currently exploited and marketed, and the prospects that ensue in the longer term (he also shows how wrong gas-price forecasts have been in the past).

As he stresses, in conclusion, with both oil and gas we must be aware that the world does not have infinite resources and, since the alternatives do not allow us, at the moment, to make up for future energy-resource shortages, it is for individuals to prepare themselves for entering the era of energy sobriety.

The Futures of the World: A Cartographic Essay in Global Foresight

In late 2010, Virginie Raisson published 2033, atlas des futurs du monde (Paris: Robert Laffont, 2010), a richly illustrated work which Pierre Bonnaure discussed in the Bibliography section of Futuribles last February. In that book, she shows the extent of the challenges facing our planet and the degree to which foresight studies have an essential role to play in interpreting them and offering various scenarios capable of providing positive solutions to problems that may at times seem insoluble. By way of some original, dynamic graphic features, this Atlas lays before us both the present, with all that it portends for future generations, and the future, with all the potential scenarios that may be possible, if only we all decide genuinely to act on them right now.

In this article Virginie Raisson outlines the motivations that led her to produce this original exercise in foresight studies and the choices she made in illustrating it graphically. In particular she shows, with this work – though this perhaps needs no repeating in our columns – that humanity’s future is not set in stone and that we all still have sufficient resources, material and intellectual, to shift it in the most desirable direction.

The Rush for Agricultural Land: The Case for Responsible Agricultural Investment in Developing Countries

Agricultural markets have for some years been affected by large fluctuations, making the prices of agricultural commodities highly volatile. The most recent vivid example of this was the marked price rise that occurred in 2008. In fact, land (and its exploitation) is tending to rank high once again among the list of safe investments and more and more foreign investors are taking a position in the agricultural sector in developing countries. What is the scope of – and what is at stake in – these transfers of agricultural assets?

Dominique Auverlot and Blandine Barreau, who coordinated a recent report on this question, describe the reality of this rush for agricultural land and the nature of the main investments that characterize it. Without denying the dangers inherent in this intervention of foreign investors in developing countries – which, as many see it, very much need their agricultural produce to feed their own populations – they show how it may also offer opportunities and play an important role in global food security. Lastly, they formulate a series of recommendations, aimed mainly at France and the European Union, for keeping these agricultural investments genuinely “responsible” and ensuring that they truly respect both the environment and the (economic, social, land etc.) rights of local populations, arguing also that this same orientation should be incorporated into the various international rules currently being developed in this area.
