Wind power and future of renewable energy Essay -- Clean Alternative E

Wind power and future of renewable energy Abstract: Due to the development of technology around the world, the need of energy is increasing every year. But, what would be the best way to produce energy without polluting the air, or depleting fossil fuels? Renewable energy would also be the best solution for this problem. Of the available sources of renewable energy, wind power shows much promise. Wind turbines have been used through many generations, and the technology continues to develop. Wind Energy provides a feasible energy alternative to traditional fossil fuels. Introduction: The need for alternative energy is a pressing issue for countries all over the world. One of the solutions this for problem is wind power, which has been in use for many thousands years. â€Å"About 5000 years ago, the ancient Egyptians used wind to sail ships on the Nile River. Later, people built windmill to grind wheat and other grains. American colonists used windmill to pump water, and cut wood at sawmill. In 1920s, they started to use it to generate electricity.† (Renewable energy trends, 2005). Besides the long known history, the ways electricity is generated through wind turbines are truly simple, too. â€Å"Turbines catch the wind's energy using blades which are mounted on a shaft. The shaft is connected, normally via a gearbox, to a generator which produces electricity. The blades and shaft are connected to the Wind power 3 nacelle, which contains the gearbox and other power mechanical components.† (Scottish executive, 2007). Wind turbines can be determined in two styles that based on the direction of the rotating shaft (axis). One is horizontal axis, and the other is vertical axis. (Figure 1).
