Mots-clés: Solaire, Energie, Afrique, Développement The Solar Energy in Africa in 2020 – Four scenarios of possible speech by the African Development Bank in 2020 Abstract: The scarcity of electricity and the lack of access to energy sources are some of the main problems faced by Africa, especially in rural society. This is highly paradoxical since Africa abounds in energy resources; unfortunately those abundant resources benefit western and, more recently, Chinese

to use a generator, converting a mechanical energy into an alternating voltage. This energy of mechanical origin is obtained most of the time starting from a source of heat, exit itself of a primary energy, such as fossil energies like oil, nuclear or a renewable energy, solar energy. One can also directly use a mechanical energy, like the hydraulic power or wind energy. Obviously the source is not inevitably mechanical, example the piles or the solar panels.

favourite destination IV – Energy in Greece Greece’s comprehensive energy policy, to establish sustainable, competitive, and secure sources of energy Wind is driving growth (= le moteur) in the renewables sector and represents a huge investment potential in Greece . It is estimated that today, 1300 MW of wind farms are operating, while the target is 7,500 MW to be installed by 2020 In future , one of the core components of Greece’s energy profile will be solar. Greece has a superb sun radiation

que les données météorologiques locales soient disponibles. Abstract - This paper presents the development of a simulation model for predicting the performance of a solar photovoltaic (PV) system operating under prevailing meteorological conditions at the site location. Stand-alone photovoltaic systems are widely used in renewable energy sources applications and it is important to be able to evaluate the performance of the installed systems. Mathematical equations developed for modelling the performance

Photovoltaic technology holds the promise of an almost inexhaustible energy source with minimal environmental impact. Significant reductions in the cost of PV-produced power are required to realize this potential. This can be accomplished through a significant increase of conversion efficiency at cell level and nanostructured inorganic structures can potentially meet this challenge. Here, limiting factors of high efficiencies in single junction solar cells are first recalled. Then, approaches with potential

eco friendly, latest netbook • Many characteristics very interesting • Also function thanks to solar collectors in addition to the battery • Hard ware, flash memory… • Weight very light (700g) Novelty • The presence of solar collector was never seen on an electrical appliance or hi-fi. It also tend to develop new operating systems • Latest generation of laptops, innovation thanks to solar collector, and all the components included. • The first netbook at less than 150€, thanks to innovation

young people aware of the dangers of the nuclear power. It targets young people and aims to make them demonstrate/march against the use of nuclear energy. According to Greenpeace, geothermal, solar, wind, water energies should be promoted/developed. Pronuclear people argue that the nuclear power is safe, not hazardous.
