Énergies Renouvelables

L'hydroélectricité reste la plus importante des énergies renouvelables. Ses apports au système énergétique sont indéniables. Offrant à la fois la possibilité de stockage à différentes échelles de temps (de l'heure à l'année), une grande flexibilité et permettant de répondre aux besoins de services systèmes, l'hydroélectricité joue un rôle essentiel dans la transition énergétique. L'hydroélectricité participe largement au développement économique des territoires. L'usage multiple de l'eau (eau potable, irrigation, soutien d'étiage, navigation) est devenu la règle. Au-delà de la production énergétique, elle est au centre des enjeux liés à la gestion des ressources en eau et au développement des territoires. Mais, dans un contexte énergétique en pleine mutation, l'hydroélectricité doit s'adapter. La question environnementale reste une priorité, avec notamment de nombreuses solutions à apporter sur la continuité piscicole, reposant sur des actions de recherche et d'innovation importantes. De nouvelles technologies sont testées, telles que le couplage énergie photovoltaïque/ STEP, l'installation d'hydroliennes fluviales, et un nouveau regard est porté sur l'énergie des marées. Ce document présente une synthèse de la conférence internationale HydroES 2019 ≪ Quel avenir voulons-nous pour l'hydroélectricité en France et en Europe ? », organisée par la SHF et accueillie par INP ENSE3 à Grenoble, les 29 et 30 janvier 2019.

Significant technical progress has been made in recent years in the development of algae-based bioenergy, and much of industrial and academic R&D projects have diverged from the biofuels strategy. This report summarizes the conclusions of a recently concluded symposium analyzing the prospects for using micro- and macroalgae as a feedstock for biofuels and bioenergy. It discusses international activities for the development of bio-energy and non-energy algae bioproducts, advances in the use of macroalgae (both non-cultivated and cultivated algae). Applications for various biochemical and thermochemical uses, bio-refining capabilities for various products, as well as an in-depth review of the process from the point of view of economy and energy sustainability are also given.

Innovative Concept

Based on resource carrying capacity, this study used the revised theory of relative resource carrying capacity (RRCC) and introduced an innovative concept of relative fossil energy carrying capacity (RFECC), which evaluates the degree of fossil energy sustainability based on the relationship between economy, population, and environment. This study took China and the United States as the study objects, took the whole country as the reference area, and calculated the RFECC of population, economic, and environmental resources from 2000 to 2018. Therefore, based on the comparative analysis, the following conclusions were drawn: (i) there is a big difference in the RFECC between China and the United States, which is manifested in the inverted U-shaped trend in China and the U-shaped trend in the United States; (ii) the relative fossil energy carrying states in China and the United States are different, mainly reflected in the economy and environment; (iii) the gap in RFECC between China and the United States has gradually widened; in general, China’s economic RFECC is better than that of the United States, while environmental RFECC and population RFECC in the United States is better than that of China; and (iv) coal and oil should be used as a breakthrough point for the sustainable fossil energy and sustainable development for China and the United States, respectively.

University campuses are normally constituted of large buildings responsible for high energy demand, and are also important as demonstration sites for new technologies and systems. This paper presents the results of achieving energy sustainability in a testbed composed of a set of four buildings that constitute the Telecommunications Engineering School of the Universidad Politécnica de Madrid. In the paper, after characterizing the consumption of university buildings for a complete year, different options to achieve more sustainable use of energy are presented, considering the integration of renewable generation sources, namely photovoltaic generation, and monitoring and controlling electricity demand. To ensure the implementation of the desired monitoring and control, an internet of things (IoT) platform based on wireless sensor network (WSN) infrastructure was designed and installed. Such a platform supports a smart system to control the heating, ventilation, and air conditioning (HVAC) and lighting systems in buildings. Furthermore, the paper presents the developed IoT-based platform, as well as the implemented services. As a result, the paper illustrates how providing old existing buildings with the appropriate technology can contribute to the objective of transforming such buildings into nearly zero-energy buildings (nZEB) at a low cost.
