below 400nm; • ultra violet radiation (UV) wavelengths greater than 800nm. Solar energy is one of the first energy used by humans (after muscular energy ). More recently, solar power, solar oven, solar water heaters, solar heating, solar photovoltaic cells have revived interest in a direct use of solar radiation 2) The value of solar distillation During the fifties and sixties, desalination was a subject of environmental concern for the authorities which convinced that the combination

some technical knowledge, but also a strong business background. My main mission was to analyze the different investment opportunities, mainly focusing on the emerging markets. For example, I worked on several sustainable development projects as photovoltaic farms in Sub-Saharan Africa. I really enjoyed assessing and synthesizing financial information and preparing documentation to assist management when making critical business decisions. Working for Harvest Power would therefore be a logical step

need to change our behavior and to have better electricity solutions with which the Earth would be preserved. Introduction Ideas of technology Video Conclusion Solar energy We can use solar energy to produce electricity. Installation of photovoltaic panels. Captors are very expensive. But energy is free. renewable, clean, and produces no greenhouse gas emissions. Wind power - conversion of wind energy into electricity, using wind turbines plentiful, renewable, widely distributed, clean

includes space heating and cooling through solar architecture, potable water via distillation and disinfection, solar hot water, solar cooking, and high temperature process heat for industrial purposes. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Even though humans have been using the sun's energy for thousands of years, solar electric technology is still very new and sometimes it's very hard to switch to a new system when you

development (design) and normal operation of systems. Currently, several simulation tools ,using HOMER, are used in academia. Thus, in this work, we present the principle of feasibility study and optimization of an stand alone hybrid system(wind-photovoltaic-diesel). Furthermore, we determined the price per kWh of electricity supplied by the stand alone hybrid system, which amounts to $ 1417 / kWh. The site considered in this study represents the Adrar site located in the south west Algeria. Thus,

The choice of materials which are not dangerous for man (banishment of the asbestos for example); the arrangement of rooms in order to facilitate energy savings either still use of new methods of energy contributions (geothermal science, photovoltaic panel) constitutes in my mind great headways. This new mode of conception and realization is characteristic of the district Bedzed in London. This district, drawn by architect's office Bill Dunster was thought to reduce considerably its ecological

installation of a net flying against insects attacks. [pic] [pic] [pic] Modular configuration allows them to adapt to all types of location ( roof balcony) and manage irrigation and save water. The energy required for their operation is provided by photovoltaic solar panels, providing another environmental benefit . For the watering, the rain water is collected from the roof , and stored into tanks placed in the these basements, control centers allow an automatic watering . For the first time, the
