Access to modern energy is essential for the supply of clean water, hygiene and health, and for the provision of reliable and efficient lighting, heating, cooking, and mechanical power. It seems clear, therefore, that the energy factor and its availability, the demand for which is growing, must be ensured over time. Moreover, considering that the world population will significantly increase in coming decades and, legitimately, all of these individuals want access to sources of energy for a better quality of life. The patterns of consumption most commonly used nowadays are expensive and highly polluting, but, most importantly, now they are almost completely exhausted. Therefore, research has to find sources of ＂alternative＂ and renewable energy in order to sustain the continuously growing global demand for energy. It is necessary, therefore, to develop and improve policies in order to change current consumption patterns, while strengthening approaches and strategies for sustainable models, applying incentives for good behavior and penalizing waste, and promoting the empowerment of producers. This paper concerns this sector and aims to highlight innovation in bioclimatic and eco-friendly buildings.展开更多

We assess the reliability, accuracy, and autonomy of low power electronic devices, their market opportunities, and their ability to enhance sustainable development. For small, portable applications that need long lifetime energy supply systems, size, width, finite energy lifetime, and the need for replacement are important drawbacks. New supply alternatives should be explored that are able to make recharging easier or to remove battery dependence altogether. A new trend in the energy sources for low power applications has emerged in recent years, involving the harvesting of the energy available in the environment to supply power for electronic applications instead of using battery technologies that provide only short, finite amounts of energy. In this paper, we describe an all-purpose module of energy harvesting from mechanical, thermal, solar and RF energy sources developed at the University of Barcelona. We provide proof of concept in order to incorporate this novel energy technology in a wide range of applications and environments.展开更多

Its birth is iconic. In a world where resources are increasingly strained, exploitation and utilization of non-renewable resources cannot meet the demand for per capita and traditional energy consumption of resources with environmental pollution worsening. In the global environment today it is not sufficient. People have to develop new sources of energy to replace the past non-renewable energy. The new energies include： wind, solar, nuclear, geothermal energy, tidal energy and bio-energy.展开更多

It is designed to assist the designer in the sizing ofPV （photovoltaic） installations. The programming structure and physical models implemented within this tool are described, and several case studies are proposed to highlight its relevance. The predicted yearly electrical energy production of grid-connected PV plants is discussed. In particular, the predicted performance of such plants is compared with that given by the PVsyst software. PVLab has a high level of flexibility, allowing its physical models and databases （e.g., meteorological data） to be modified according to the user＇s needs. This is made possible through the use of expertise applied to all of the computing steps, and to the MATLAB development environment. The user＇s ability to control the source code itself will allow much greater progress to be made in the field of renewable energy applications than with PVsyst, which is currently the commercial reference.展开更多

Under the adequate sunshine condition, the fresh air is directly delivered into the indoor environment after being heated by the solar collector. When the sun radiation is reduced, the heated air temperature can not satisfy the need of supply of air temperature.The main heat source is changed to phase change heat storage equipment instead of solar energy. The system adopt heat pipe for a high-efficiency and isothermal heat transfer which recover the shortcomings of PCMs such as： low coefficient of thermal conductivity and poor thermal efficiency. This article establishes the physical model of phase change solar energy fresh air thermal storage system and creates the mathematical model of its unsteady heat transfer to simulate and analyse the operation process by using Fluent software. The results of the study show that, compared to normal fresh air system, the phase change solar energy fresh air thermal storage system has a significant improvement in energy saving and indoor comfort level and will play an important role in the energy sustainable development.展开更多
