GREEN WIND POWER – A HEALTHY WAY TO MEET THE WORLD'S ENERGY NEEDS

Latest Breaking News - News and Society - Viewing: Green wind power – A healthy way to meet the world's energy needs Tuesday, May 12, 2009 The Green wind power has been harnessed since past two decades, and the advantages of the green wind power have caught the eyes of the big power companies to invest on big wind turbines and setting up massive wind farms. Initially, the wind farms were limited to power generation only for residential purposes such as generating power for farm machines and houses. However, over time the application of this form of power in commercial terms grew popular. As per the recent facts and figures, over 600 wind turbines have been incorporated for the generation of green wind power in the state of Iowa. More and more countries are entering into the production of green wind power with every single passing day. With the technological developments the size of turbines is increasing, and so is the production in the wind farms. Consequently, turbines even as high as 240 feet tall have been incorporated into the production of green wind power. Moreover, as many as 150 turbines have been made use of, on a single land-piece. Hawaii boasts of the highest wind turbine ever built, which stands as tall as 20 stories high, with massive 100yard-blades accounting to about size of a soccer field. Considering the classification of wind turbines, mainly they come in two types namely the horizontal axis and vertical axis turbines. The horizontal one is popular than the vertical ones, since the horizontal ones are equipped with rotor blades towards the topmost part of the tower. On the other hand, the vertical axis turbines come with vertical sails, which operate similar to the horizontal ones. While the sail traps the wind energy, this energy in turn is harnessed to rotate the shaft of turbine that ultimately powers a dynamo, thus producing green power. There are several specialized turbines built for operating off the shore, as well as on land. Denmark has been reported to make extensive use of horizontal axis turbines to generate green power. Looking into technical details, people often get confused with the windmills and turbines. These green wind turbines surely work similar to the windmills, but they generate electricity, while the windmills are used for grinding grains and performing similar tasks. Moreover, the green wind power turbines work just in the reverse way as that of a normal fan, which makes use of the blades and electricity to generate wind. On the contrary, wind turbines convert the wind electricity into electrical power and helps in generation of large amounts of electricity. This form of electricity is eco-friendly, and doesn't exhaust the conventional resources of the planet, and is also available even for commercial purposes. Lastly, looking at the specs of the wind turbines, they've been built with perfection to the utility scale, and are capable of producing electricity anywhere from 50 KW up to a whopping 750 kilowatts of power. Therefore, the usage of green wind power must be promoted for environmental benefits, while they also offer a cheaper alternative to conventional sources of energy as well.
