Renewable energy sources (solar. wind. tidal. etc.). which are unlimited and have a fair distribution in the world. are an alternative to the depleting fossil fuels (coil. petroleum. natural gas. etc.). It is necessary to identify the right technologies and methods to make more effective use of renewable energy sources …

The use of traditional fossil fuels to generate electric energy causes serious environmental problems. such as climate change. global warming. air pollution. and acid rain. among others. On the other hand. the consummation of electric energy on the planet increases using due to modern society’s increasingly use of equipment and …

Photovoltaic (PV) module is considered as the most reliable component in a PV system. and its life time is expected to be more than 20 years. Degradation. however. decreases the PV power delivery capacity over time. A thorough understanding of PV module degradation is required to make better use of …

Harvesting energy from the sun is attracting increasing attention due to the challenges arising from our continued dependence on fossil fuels. In the past two decades. polymer photovoltaics (PV) based on bulk-heterojunction (BHJ) structure have become a promising alternative energy option due to their lightweight properties. environmental friendliness. and solution …

Solar energy radiation is essential in plant physiology and pathophysiology hence its knowledge is fundamental for example. to estimate evapotranspiration (Gocić et al.. 2015. Petković et al.. 2015) and to predict infection risk of some fungus diseases (Katsantonis et al.. 2017. Dalla Marta et al.. 2008) that are needed to …

The role of energy is vital to human well-being and it is also crucial for economic development and energy fosters economic growth. Access to sufficient energy resources is a serious global concern. particularly in developing countries that do not have access to a secure supply of energy. Worldwide primary energy …

The monitoring of human activity is. on the technical point of view. a continuous challenge in terms of design and development of innovative smart and wearable systems that aims to the dimension reduction and to the increase of the energy autonomy. These devices can implement many features. such as the …

Wind energy. an alternative to conventional energy produced by burning fossil fuels. is a renewable and clean energy which produces no greenhouse gas emissions during operation. consumes no water. and uses only a little land. With the rapidly growing world population. it is essential to increase the production of energy …

The increase of the demand and consumption of energy resulting from technological progress and from advancement in human development are seen as the most important factors in the acceleration of climate and environmental changes observed and described by the scientific community. Energy is fundamental because is one of the most …

Wind has been used as an energy source since ages. The power of wind was used to sail ships. to mill grain and to pump water. Wind power is currently considered as one of the most viable alternatives to fossil fuels because it is renewable. widely distributed and clean with …
