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, and produces no greenhouse

can sometimes be highly toxic and harmful for the environment and living organism. Alternative Sources • Nuclear energy This source of energy can revolutionise the world we live in particular in terms of electricity production. This source of power is free from carbon emissions. Since the oil crisis of the early 70’s, the industrial powers have been constructing nuclear reactors across the world for the production of electricity. There are about 500 such reactors devoted to peaceful uses.

two weeks, for my Electrical Engineering diploma. Ecoenergy are located in Nantes near Sautron. It is quite a large company with 5 branches in France, who specialize in Renewable Solar energy. The company is quite new; it was started in 2007, by Eric Lecoq. And in 2010, it changed its name Ecoenergy to Vuelto Solar. This is how work is organized: * First, a salesman visits the client * Then, he inspects the site, takes data and sends the data to the design department. * After that

health at stake/in jeopardy. Sony & Apple have promised to adopt more environment friendly/sustainable practices. Greenpeace has decided to make a comic strip which is supposed to be funny, entertaining but about a serious issue namely a nuclear power station in Indonesia which sounds quite paradoxical. Smart = Elegant or clever. The words ending in –ate are stressed on the second syllable before –ate. The comic strip is about two teenagers in Indonesia who decide to travel time and go back in

of this gas in the atmosphere is quickly going to lead(drive) to a reheating of the ground temperature and, doubtless, to important climatic disorders. The renewale énergies don’t miss : the water of waterfalls, ( the hydro-electric power), the sun ( the solar energy), the wind ( the wind energy), the heat of the ground bassement ( the géothermal energy) and others else ! But they’re there still for their beginning, and are relatively expensive. Their developement are made by governmental subsidies

majorité des nouvelles installations. Les cinq plus grandes firmes fabriquant des cellules photovoltaïques se partagent 60 % du marché mondial. Il s'agit des sociétés japonaises Sharp et Kyocera, des entreprises américaines BP Solar et Astropower, et de l'allemande RWE Schott Solar. Le Japon produit près de la moitié des cellules photovoltaïques du monde, mais c'est en Chine que la grande majorité des panneaux sont assemblés. Le Japon est lui-même un des plus grands consommateurs de panneaux solaires

photovoltaic effect, which is the transformation of solar energy ("photon") into electricity ("Volt") was discovered in 1839, by the French physicist A.E.Becquerel. Its use in industry only began in the 1960's, mainly for space industry applications. Then, in the 1970's to others applications have been invented to respond initially to industrial needs, but eventually to the isolated spaces. The current context is in favor of photovoltaic. The photovoltaic solar energy is able to meet a growing demand for

understanding of the basic concepts of transportation fuels. The first chapter, “Introduction to energy sources”, comprises one fifth of the book; the chapter goes into detail on global energy sources, especially renewables, i.e., biomass, hydro, wind, solar, geothermal, and marine. The second chapter is entitled “Biofuels” and covers the main liquid biofuels such as bioethanol, biomethanol, and liquid fuels from Fischer–Tropsch synthesis. The third chapter, “Vegetable oils and animal fats”, covers the
