Renewables and Efficiency

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 …

Renewable growth will be largely driven by China. which is predicted to be responsible for 41% of expansion.

Durability and Reliability of Polymers and Other Materials in Photovoltaic Modules describes the durability and reliability behavior of polymers used in Si-photovoltaic modules and systems. particularly in terms of physical aging and degradation process mechanisms. characterization methods. accelerated exposure chamber and testing. module level testing. and service life prediction. The …

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 …

During the last decade. renewable energies have taken on a great importance in the development of some countries. Developing this energy is increasingly the axis explored by the scientific community. The energy can be extracted from many sources. to cite fossil. solar and wind.Wind turbine technology has developed rapidly in …

Despite the reduction of solar installation cost by a ratio of 10 during the last 20 years. still conversion efficiency of PV panels remains an important parameter to take into account when designing solar system for residential applications. Therefore. an efficient MPPT algorithm plays a key role to harvest optimum …

The new cooperation agreement is an extension of the original 114 million euros climate fund that Finland established in collaboration with the IFC last year.

Wind energy source (WES) is one of the most prominent sources of electrical energy in years to come. WES. as a renewable source. has no impacts on the climate issues and greenhouse gases (GHG) emissions. The increasing concerns about environmental problems demand green. renewable. and sustainable ideas. Wind turbines along …

Current researches are focused on the electrical production using multi-sources energy conversion systems. Photovoltaic generators (PVG) have maximum power points (MPP) corresponding to meteorological conditions. cell area and load. In Wind generator (WG) when the wind speed varies considerably. the variable speed generation (VSG) is more noticeable than fixed speed …
