La gestion de la distribution de l'énergie électrique produite à partir de sources renouvelables comme l'énergie solaire et l'énergie éolienne est un verrou technologique pour améliorer les performances et la stabilité de l'ensemble des processus de transfert d'énergie. Ainsi, les recherches sur les lignes électriques utilisées comme supports de communication sont très prometteuses pour la gestion d'installation de petites et moyennes puissances comprenant de nombreux générateurs, pas forcément conçus initialement dans une démarche de fiabilité. En outre, cette nouvelle possibilité de gestion permet d'améliorer les performances et la stabilité dans le processus de transfert global d'énergie. Cette étude est particulièrement orientée vers une architecture distribuée pour la gestion photovoltaïque parallèle et/ou multi-générateurs incluant d'autres technologies telles que l'éolien par exemple connectés sur un réseau à courant continu servant également de support de communication tel que le système CPL. Le CPL, en utilisant la technique de modulation, permet le transfert de l'information telles que la température, la puissance instantanée, l'auto-test etc... nécessaires pour optimiser la production d'énergie. Le but de ce travail consiste en l'étude d'une solution CPL conçue pour travailler sur bus HVDC reliant des systèmes de production d'énergie renouvelable. Les circuits développés pour le CPL seront donc considérés comme des interfaces entre le convertisseur intelligent DC-DC et le bus HVDC. Ils seront basés sur une partie matérielle constituée d'un émetteur-récepteur intégrant une interface de modulation-démodulation sur le bus HVDC et un processeur de signal assurant le traitement des diverses informations échangées entre les capteurs d'entrées et le monitoring.

Unless action is taken now to make agriculture more sustainable, productive and resilient, climate change impacts will seriously compromise food production in countries and regions that are already highly food-insecure. The Paris Agreement, adopted in December 2015, represents a new beginning in the global effort to stabilize the climate before it is too late. It recognizes the importance of food security in the international response to climate change, as reflected by many countries prominent focus on the agriculture sector in their planned contributions to adaptation and mitigation. To help put those plans into action, this report identifies strategies, financing opportunities, and data and information needs. It also describes transformative policies and institutions that can overcome barriers to implementation. The State of Food and Agriculture is produced annually. Each edition contains an overview of the current global agricultural situation, as well as more in-depth coverage of a topical theme."

Increasing the world's population to 9 billion by 2050 will lead to an increase in the need for raw materials that support basic human activities, as well as all developments in new technologies, mobility, energy. If current trends continue, projections indicate that to meet global needs by 2050, we will have to extract more metals from the subsoil than mankind has extracted since the inception. It is against this backdrop of strong demand for metals that energy and the transition to decarbonized energy production arise. The stakes associated with energy and mineral raw materials are indissociable because metals are necessary to build the infrastructures of production of energy, its storage and its distribution, but also because the energy is necessary to produce the raw materials. The offshoring of production weighs on the adaptive capacities of Western non-producing countries, which are currently confronted with the economic, political and technological emergence of producer countries such as China. Industries in developed non-producing countries are thus placed in a situation of great dependence on imports of fossil energy, but also mineral resources. In this highly competitive context, the stakes in raw materials and energy are considerable. Mineral Resources and Energy addresses these topics from the point-of-view of needs, notably to ensure the energy transition and primary production, recycling, technological innovation, economic and social issues. A chapter is devoted to modeling in order to understand and integrate these couplings in a global model. Increasing the world's population to 9 billion by 2050 will lead to an increase in the need for raw materials that support basic human activities.

Indonesia is the largest country in the Association of Southeast Asian Nations (ASEAN), accounting for around two fifths of the region's energy consumption. Energy demand across the country's more than 17,000 islands could increase by four fifths and electricity demand could triple between 2015 and 2030.While reliance on domestic coal and imported petroleum products has grown, Indonesia has started adding more renewables to its energy mix. The country has set out to achieve 23% renewable energy use by 2025, and 31% by 2050.REmap - the global roadmap from the International Renewable Energy Agency (IRENA) - addresses this challenge, presenting a range of technology and resource options, along with key insights on the opportunities and challenges ahead.As this REmap country report shows, Indonesia could feasibly exceed its current goals and deploy even more renewables. In fact, the country could reach its 2050 target two decades sooner - by 2030.
