This paper presents a developed method for controlling multi-renewable energy generators. The control system depends basically on three sensors (wind anemometer, solar sensor, and voltage sensor). These sensors represent PLC’s analogue inputs. Controlling the output voltage supply can be achieved by an enhanced method of interlocking between the renewable energy generators, depending on those s...

renewable energy is derived from the natural processes that are replenished constantly. in its various forms, it derives directly from the sun, or from the deep heat generated from the earth. it isdefined as the electricity and heat being generated from solar, wind, ocean, hydropower, biomass, geothermal resources, biofuels, and the obtained hydrogen from the renewable resources. the renewable ...

Glossary Amorphous silicon (a-Si): A glassy alloy of silicon and hydrogen (about 10 percent) used in thin-film photovoltaic solar cells to convert sunlight to electricity. Anaerobic Digestion: Combustible gas called biogas produced from biomass through low temperature biological processes. Anthropogenic: Man made. Bagasse: The fiber residue that remains after juice extraction from sugarcane. Ba...

The use of polymers from natural resources can bring many benefits for novel polymeric nanoparticle systems. Such polymers have a variety of beneficial properties such as biodegradability and biocompatibility, they are readily available on large scale and at low cost. As the amount of fossil fuels decrease, their application becomes more interesting even if characterization is in many cases mor...

B ecoming independent of crude oil imports, mainly from the Middle East, is an urgent concern for many countries all over the world. In order to secure a sustainable energy supply, especially in the transportation sector, governments need to apply policies that promote the use of renewable energy technologies. The dependence on crude oil imports decreases as the production of total energy from ...

nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...

Projections are important tools for long-term planning and policy settings. Renewable energy sources that use indigenous resources have the potential to provide energy services with zero or almost zero emissions of both air pollutants and greenhouse gases. Currently, renewable energy sources supply 14% of the total world energy demand. Renewable energy is a promising alternative solution becaus...
