Wind power

cette guerre, doit faire face à des réactions hostiles émanant d’une partie de la jeunesse. Ainsi se développe aux Etats-Unis, le mouvement hippie qui prône l’amour, la paix, la liberté. C’est l’époque des messages d’espoir, d’insouciance: Flower Power, Peace and Love, Make Love, not War…Refusant d'entrer dans le jeu politique ou d'opposer la force à la force, de nombreux hippies décident de se retirer de ce monde violent et sans attrait ; Ils choisissent principalement la Californie où de nombreuses

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. Most of

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

to stabilize around 500 ppm. There are many possible wedges, including improvements to energy efficiency and vehicle fuel economy (so less energy has to be produced), and increases in wind and solar power, hydrogen produced from renewable sources, biofuels (produced from crops), natural gas, and nuclear power. There is also the potential to capture the carbon dioxide emitted from fossil fuels and store it underground—a process called "carbon sequestration." In addition to reducing the gases

course to be accepted. These projects are possible because of previous actions like the British Energy’s purchase (that is 8 more power stations), the purchase of half of the Constellation Energy’s (US) nuclear power stations, the intensification of the partnership between EDF and CGNPC (China Guangdong National Power Co.) with the creation of Taishan Nuclear Power Joint Venture Company to buy two third gen. nuclear reactors and the creation of a joint-venture with Enel company to create 4 third

Sensitivity analysis with wind speed data, solar radiation, diesel price and fuel cell cost was done. A unit of desalination consumers 25 kW h/d with a 4.6 KW peak power demand was considered as the stand-alone load. It was fond that, a wind-diesel-battery hybrid system is the most suitable solution at present. However, with a reduction of fuel cell cost to 15% of its current value, a wind-diesel-fuel cell system would become a superior choice in the regions where the annual average of wind speed pass 6 m/s
