Shell's Global Scenarios. Production of Hydrocarbons, Energy Security and Carbon Saving

The oil companies are among the businesses most affected by the future of fossil fuel resources. Consequently they are trying to foresee what might happen and prepare for it. Shell, for example, has been drawing up energy scenarios since the 1970s. Albert Bressand was in charge of Shell's most recent foresight exercise, looking ahead to 2025, which presented a range of "global" scenarios that tried to envisage the likely developments with regard to energy.
After recalling the old but still relevant debate about the risks of shortage (Hubbert's peak), he stresses the importance of certain factors of discontinuity which are too often overlooked: the possibility that the link between energy and growth will be broken; the increasing impact of climate change on energy policies; the important role of politics and national issues (especially arising from the need to ensure energy supplies are secure). Albert Bressand takes the opportunity to paint a fairly full picture of the ins and outs of the debate (technical aspects, geopolitical concerns: United States, China, Russia, India, Middle East, etc.).
Lastly, Bressand summarizes Shell's three global scenarios down to 2025, which are built around three goals (security, efficiency and social cohesion) and which aim to take Hubbert's analysis a stage further by adapting it to present circumstances. In his view, it is essential, if we are to have a reliable sense of our energy prospects, to take into consideration - in addition to geological factors and world demand - the preconditions for investment, fiscal policies, regulatory and environmental policies, and international relations, both between producers and consumers and among the most powerful nations.

The Outlook for Energy and the Reality Principle

An energy crisis threatens: while scientists disagree about when it will happen, most of them agree that a shortage of fossil fuels is likely to occur before the end of this century. Faced with this threat, some propose to trust in technology to come up with new solutions on the production side (using hydrogen, improving nuclear methods, etc.): "technological utopias", according to Benjamin Dessus. Others try to think of ways in which lifestyles might be changed - and hence consumption - in order to bring them into line with existing resources within varying time-scales (a systemic approach), and so showing how much room for manoeuvre there is.
Benjamin Dessus, who has long argued strongly in favour of policies to check energy consumption, outlines the main points in the debate about energy prospects and ways of limiting CO2 emissions. The worst outcome (rampant climate change), he says, is likely but not unavoidable. There is an alternative: not the development of new production methods that are supposed to be less damaging for the environment, though sometimes utopian, but the mobilization of the whole population in support of a change in patterns of consumption and - why not? - in the longer term, of a transformation of production methods.

Biofuels for Transportation : Global Potential and Implications for Sustainable Agriculture and Energy in the 21st Century

Les biocarburants comme l’éthanol et le biodiesel peuvent réduire significativement notre dépendance au pétrole, selon ce rapport du Worldwatch Institute pour le ministère allemand de l’Agriculture, de l’Alimentation et de la Protection du consommateur. En 2005, la production de biocarburants a dépassé 670 000 barils par jour, l’équivalent de 1 % du marché total des carburants de transport. Bien que le pétrole représente encore 96 % du carburant de transport, la production de biocarburants a doublé depuis 2001 ...

Demain, serons-nous tous des végétariens ? 2020, que mangerons-nous ? Enjeux pour les filières agricoles et agroalimentaires normandes

L'objectif de cette étude est d'analyser les évolutions des comportements alimentaires des Européens afin d'en évaluer l'impact sur les débouchés de l'agriculture normande à l'horizon 2020. Pour ce faire, sept variables ont été identifiées, dont deux majeures : la croissance globale du revenu (produit intérieur brut) et la répartition de celui-ci dans la population. En effet, l'afflux de revenus supplémentaires n'a pas le même effet sur les dépenses alimentaires, selon qu'il bénéficie ...

World Agroforestry into the Future

L'agroforesterie, un système agricole associant les arbres (ou autres plantes ligneuses vivaces) et cultures sur une même parcelle agricole, est porteuse de nombreux espoirs pour les pays en développement. Depuis une trentaine d'années, la recherche agricole met à l'honneur cette technique pourtant traditionnelle chez les agriculteurs des pays tropicaux et subtropicaux. Aujourd'hui, environ 1,2 milliard de personnes subsisteraient grâce aux pratiques agroforestières. Le rapport World Agroforestry into the Future a été publié par le World ...

Du Rare à l’infini. Panorama mondial des déchets 2006

Dans ce rapport 2006 sur la situation des déchets dans le monde, les auteurs partent du constat que les hommes modernes ont oublié les vertus du recyclage et de la rareté, et qu'ils devront pourtant apprendre à les redécouvrir pour éviter l'épuisement de leurs ressources et la saturation de la planète. En effet, si tous les déchets ont un coût de collecte, certains peuvent être traités et valorisés, et redeviennent alors des ressources. Les auteurs ont réalisé une ...

The End of Cheap Oil. Why the Data about the Reserves Are so Unreliable and Controversial

The world economy cannot function without oil, notably because the transport sector relies so heavily upon it. Yet the forecasts of supply and demand for hydrocarbons differ widely depending on the expert source consulted.
Even though they are not much discussed in the institutional publications, major controversies surround the estimates of the total reserves that could be extracted in future. The most optimistic forecasts are based on the fact that the amount of proven reserves has never stopped growing over the last 50 years, thanks above all to technological progress and the exploitation of new, deep-sea fields; the optimists assume that past trends will continue and they reckon that there is no reason to fear shortages for another 40, if not 80, years.
By contrast, the most pessimistic experts argue that oil is a finite resource and the main oil-producing regions were discovered long ago. Since consumption rates now exceed discovery rates and technical progress has its limits, they calculate on the basis of discovery rates in the past that conventional and unconventional oil production might reach a maximum of 90 million barrels per day by 2015-2030, but after that it will decline inexorably.
Jean Laherrère, an expert on oil reserves, sums up the present situation and the forecasts of likely future changes in world oil reserves. His approach is rather pessimistic, stressing that the published figures on reserves tend to be highly political and must be viewed with caution, above all because there are no agreed definitions of what is being evaluated. He presents the various estimates of final hydrocarbon reserves (i.e. total production plus known reserves plus estimates of undiscovered reserves), and the range of factors affecting the forecasts. His conclusion does not beat about the bush: we must quickly check oil consumption (if necessary by raising prices significantly) if we are to satisfy our future energy needs.

Accepting the New Century

This article by Pierre Radanne summarizes in a few pages the key challenges raised by the third energy crisis that has been affecting the world for the past year or so. He first offers a brief description of the cyclical nature of energy and then goes on to describe how this recent crisis developed, stressing the way that concerns about climate change have put the present oil shock on a very different plane to previous ones. The challenge now is at a much broader level, relating to how people live: Western lifestyles cannot be adopted by the whole planet; consequently it is imperative that the industrialized countries seek new patterns of behaviour that reduce energy consumption. Pierre Radanne argues that public authorities, especially in Europe, must rank their priorities and establish long-term strategies, involving a certain "re-regulation" of the energy sector. He concludes that it is essential to be equipped to make a success of the 21st century by using the energy sector as a vector for tackling the problems of climate change and an approach to creating a new form of civilization for the whole planet.

Renewable Energy Sources as a Key Factor in Tackling Consumption

As is suggested by one of the conclusions of the French Interministerial Mission on the Greenhouse Effect in 2004, the emissions of greenhouse gases cannot be reduced in France without an enormous effort to address energy consumption (energy saving) alongside initiatives to develop renewable forms of energy.
The demand side of the equation (addressing consumption) is discussed in this issue by Véronique Lamblin. On the supply side, in the context of possible shortages in the longer term (probably within a matter of decades) of fossil fuel stocks (mainly hydrocarbons), renewable energy sources are an important option to explore, alongside greater use of nuclear power. Jean-Louis Bal and Bernard Chabot, both specialists in renewables, describe the main features of solar, wave, wind, biomass and geothermal power, their place in the total energy picture, and more specifically in Europe and in France, as well as their prospects for growth in the medium term.
They discuss the contributions of renewables to the production of electricity and heat and as fuel. They then argue that renewables could make up a non-negligible part of energy supplies via quite simple applications in housing and transport, for example. But this, too, would require a certain willingness to intervene on the part of governments. Germany and Japan, for instance, have already invested successfully in this approach, whereas France is lagging behind.
