[en] A CIRED team has just published a study on how to meet the demand for electricity without nuclear or fossil fuels. She concluded that it would not cost more than it does today. With the hypotheses of the cost of wind power and photovoltaics that it has retained, it is also possible to calculate that it would cost less than with new nuclear reactors. In addition to the costs of wind and photovoltaic production, the CIRED study retains a set of explicit or implicit assumptions which deserve to be commented on the level of electric power consumption, the stability of the network, the efficiency of the storage means, the reception by the population of tens of thousands of wind turbines and thousands of square kilometers of photovoltaics, the consumption of critical materials and dependence on foreign countries, the loss of a nuclear know-how that the world will need, the vulnerability of an electrical network based on digital communications.
[fr]Une equipe du CIRED vient de publier une etude sur la facon de repondre a la demande d'electricite sans nucleaire ni energie fossile. Elle conclut que cela ne couterait pas plus cher qu'aujourd'hui. Avec les hypotheses de cout de l'eolien et de photovoltaique qu'elle a retenues on peut aussi calculer que cela couterait moins cher qu'avec des nouveaux reacteurs nucleaires. Outre les couts de production eolien et photovoltaique, l'etude du CIRED retient un ensemble d'hypotheses explicites ou implicites qui meritent d'etre commentees sur le niveau de consommation d'electricite, la stabilite du reseau, l'efficacite des moyens de stockage, l'accueil par la population de dizaines de milliers d'eoliennes et de milliers de kilometres carre de photovoltaique, la consommation de materiaux critiques et la dependance a l'egard de l'etranger, la perte d'un savoir faire nucleaire dont le monde aura besoin, la vulnerabilite d'un reseau electrique reposant sur les communications numeriques.

[en] This parliamentary report first recalls the objectives of the French energy policy as they are defined in a decree related to a preliminary dialogue for the PPE and the low-carbon strategy, in terms of mandatory energy savings, and regarding the carbon budget specific to the international transport and the French carbon print. Then, it discusses measures which have been already applied, are about to be applied or foreseen in favour of climate, and notably regarding the shutting down of coal-fired plants, to housing energy performance. The next parts present and comment legal and regulatory measures related to environmental assessment, to the struggle against the fraud on energy saving certificates, to the adaptation of the law to the case of overseas territories, to energy regulation, and to gas and electric power sales regulated prices.
[en] Whereas the French law related to energy transition for a green growth defined the objective of energy self-sufficiency in overseas territories by 2030 (i.e. a higher objective than for the metropolitan mainland), this report proposes a synthesis and comparative analysis of studies performed for 6 territories (Mayotte, Reunion, Guadeloupe, Martinique, and Guyana by 2030, and Corsica by 2050). The main lessons learned from these studies are highlighted: possibility of a 100 pc renewable electricity mix, issue of energy management, high reduction of the importance of Diesel plants, significant share of varying wind and photovoltaic energies, decrease of the costs of the produced energy, electricity systems appeared to be steady. It discusses the context and conditions to reach the defined objectives. It presents the methodology and main hypotheses of the performed studies: elaboration of a data set, optimisation of trajectories of evolution of the electricity mix for 5 scenarios, ex-post economic analysis, modelling of the 5 scenarios for each territory. Results are globally presented (an expected decrease of global costs of electricity, an electricity system which could remain steady in front of significant incidents), and the limitations and perspectives of the study are discussed. Results are then presented for the six different territories (data in 2017 and 2030, renewable potentials, mix analysis for each scenario, economic analysis of scenarios, focus on a specific scenario).
[fr]La loi relative a la transition energetique pour la croissance verte (LTECV) a fixe comme objectif de parvenir a l'autonomie energetique dans les departements et regions d'outre-mer (DROM) a l'horizon 2030. La Collectivite Territoriale de Corse vise ce meme objectif pour 2050. L'ADEME a souhaite mener une etude pour evaluer les implications techniques, organisationnelles et economiques qu'aurait un mix electrique tres fo tement renouvelable dans ces territoires, pour la majorite insulaires (Mayotte, La Reunion, la Guadeloupe, la Martinique, la Guyane et la Corse). Le vecteur electrique, permettant une production locale basee sur les energies renouvelables, et adapte a de multiples usages en substitution a des energies fossiles importees, pourrait jouer un role preponderant pour atteindre cet objectif ambitieux d'autonomie energetique. A l'heure de la revision des Programmations Pluriannuelles de l'Energie des ZNI (PPE), cette etude se veut un outil d'aide pour les instances decisionnelles afin de nourrir la reflexion des parties prenantes et ouvrir le champ des possibles.
[en] Whereas the former USSR and Asia are the most nuclear regions in the world (164 reactors), and as their nuclear policies has been put by the Fukushima accident into question again, this paper proposes an overview of the situation of nuclear electric power production in these countries. It appears that Russia and China have a very offensive policy of development of nuclear (sheets are proposed with indications and brief comments on resources and on the composition of the electricity mix, on economy, infrastructures and organisation, and on the nuclear policy for Russia and China). The cases of Armenia, Ukraine, Belarus and Kazakhstan are described as countries wishing to initiate or to increase their nuclear power production (a sheet is proposed for Ukraine). Then, the paper addresses the cases of Japan, South Korea and Taiwan which reconsider their will to phase out nuclear (sheets for Japan and Korea). A brief synthesis is finally proposed.
[en] Reporting on the climate action of cities and regions in the context of the pandemic and the renewal of national contributions to the Paris Agreement. Each year, the Climate Chance Observatory proposes a summary of the progress made in terms of climate action and published by cities and regions around the world. Although the absence of consolidated and comparable data remains a challenge, this does not mean that there is no action or mobilisation. The analysis of the remarkable evolution of emissions at the local level, the monitoring of the development of the main international initiatives led by networks of local authorities, and publications of academic and specialised literature, make it possible to draw global trends. The formulation, implementation and monitoring-evaluation of local climate actions is a complex process that requires both the support of States and a proper consideration of the inhabitants' needs. This is why our monitoring is accompanied by analyses of multi-level governance and the localisation of Sustainable Development Goals. The reduction of GHG emissions by European cities is encouraging. However, in a context of mass adoption of carbon neutrality objectives, the monitoring of the impact of local climate policies remains scattered and poorly consolidated, even at the national level. The mobilisation of local governments and the structuring of their climate action is continuing. Although international initiatives show a certain dynamism in Latin America, Europe and North Africa, they do not account for the action of Asian cities and regions. Even in times of Covid-19, local governments remain places of innovation and experimentation for climate policies. At the city level, the densification of services is now seen as the remedy to the health and climate crises. Few of the renewed national contributions to the Paris Agreement mention governance mechanisms that integrate local and sub-national governments, except in Latin America. Their sectoral approach to tackling local emissions reduction masks the potential of spatial planning and local governance. Multi-level governance in G20 countries: our first case studies (Germany, Canada, France, Brazil) show that few cities are subject to climate obligations, whose action relies on the disparate support of federal and federated states. The lack of harmonisation of monitoring methods makes it difficult to integrate the potential of cities into national strategies. Agenda 2030: after a few years in the adoption phase, local governments are embracing the Sustainable Development Goals (SDGs) to cushion the socio-economic shocks of climate policies. Despite the lack of funding, driven by the dynamic exchanges between scientists and decision-makers, adaptation to climate change is accelerating within regions and cities.
[en] Wolfgang Palz has been in charge of the solar energy in the European Commission. In this note, he analyses the 'hydrogen' phenomenon. He first outlines the first interest in green hydrogen as it appeared in an R and D programme launched in 1975 by the EU. He notably outlines the strong relationship between solar and hydrogen, and the one between hydroelectricity and hydrogen. In a second part, he discusses the present situation where green hydrogen is on the agenda, notably in relationship with climate change issues, and in a context of strong development of renewable energies. He briefly evokes the present situation of hydrogen markets, and discusses the challenge of an intensification of green hydrogen development on energy markets (still small share in individual vehicles, challenges related to this issue, issue of hydrogen competitiveness). He comments the evolution of the penetration ratio of renewable energies since 2000, the definition of new strategies of development of green hydrogen in the EU, in some of its member states, and in other countries. He indicates some industrial initiatives and projects related to green hydrogen.

[en] After a discussion of the characterization of the security of supply (match between supply and demand on the long and medium terms), and having shown that the planned closure of steerable capacities in Europe should be better taken into account in order to guarantee the security of supply before 2030, this note comments the rate of development of intermittent renewable energies. It notices that these energies have a smaller guaranteed power, outlines that France, Germany and Belgium display the highest deficits of steerable power, that a high share of intermittent renewable energy within the energy mix increases the probability of grid destabilization, and increases the steering complexity, and that it is necessary to adapt grids and to develop demand flexibility. The authors outline that energy transition is poorly coordinated at the European level, which increases this weakening. Some recommendations are finally stated. An appendix presents the main hypotheses, uncertainties and observations related to this study.
[en] After the statement of several propositions and recommendations, this report states and discusses the option of the CESE on the content of the bill project related to the struggle against climate change. It addresses different issues which correspond to different chapters of this bill project: mobility (alternatives to individual vehicles and cleaner vehicles, optimization of goods road transport, better organisation of mobility, limitation of emissions by air transport and development of train-plane inter-modality), housing (building renovation, decrease of energy consumption, struggle against artificialization of soils, protection of ecosystems), food (support to a healthy, sustainable and low-emitting food), consumption (information and education, advertising regulation, development of bulk selling and of returnable glass), production and work (economy greening, adaptation of work to ecological transition, protection of biodiversity and ecosystems, renewable energies for all and by all). Some transverse recommendations are also stated regarding the funding of climate policies, the general design of policies and of governance, and the arrangement for objective follow-up and correction of noticed deviations.
[fr]Le CESE, saisi par le Premier ministre, a examine le projet de loi portant lutte contre le dereglement climatique et renforcement de la resilience face a ses effets. Cette loi doit permettre d'atteindre les objectifs fixes au niveau national et international, dans un esprit de justice sociale. Le CESE s'est prononce a plusieurs reprises sur la politique climatique et a constate que la France ne se situe pas sur les trajectoires prevues par sa Strategie nationale bas-carbone. Ce projet de loi ne parait pas en mesure de redresser la situation climatique et de prendre en compte les inegalites sociales. Alors qu'il faudrait tripler le rythme annuel de reduction des emissions et les diviser par six d'ici 2050, les mesures apparaissent souvent limitees, differees ou soumises a des conditions telles que leur mise en oeuvre a terme rapproche est incertaine. Les rares estimations d'impact fournies font apparaitre leur insuffisance. Le CESE assortit ses analyses de preconisations pour progresser.
[en] This publication comments the content of a report issued by RTE and the IEA on the conditions for a technical feasibility of scenarios exhibiting a high penetration of renewable energies (ENR) in France. It indicates the four conditions to be met for a security of supply and for the integration of very high proportion of renewable energies into a large scale electricity system: stability of the electricity system, supply security, operational reserves, grid development. These four conditions and the associated technical feasibilities stated in the RTE-IAE report are then discussed. The authors finally discuss whether a 100 pc renewable energy objective is actually to be wished.
