South Australia is one of the leading states with great capacity of installed wind turbines. Recently the regional labor government had set a 50% renewable energy target for 2025, in which wind power projects like Ceres project and Horndale project would take that investment to 50% (Vorrath, 2014). This is a strategy which is being used to reduce the amount of greenhouse gases, which is believed to be caused by non-renewable energies. As a result the last two coal-fired power stations are set to close early next year. This was announced by Alinta Energy which is coal based, located in Port Augusta (World Today, The (ABC), 2015). In account of what has been said by Tristan Edis an energy analyst and editor of climate spectator, this early closure of Alinta Energy plants is due to competition from wind energy (World Today, The (ABC), 2015). Furthermore, wind energy production has different perspectives which have been taken into account recently. These perspectives include social, economic and environmental issues. The major issue raised against wind power generation, based upon social view, is about health impacts on people living close to wind turbines and the unsightly features to the environment. Though, all these points have not justified so far further research is still in process.
1.2 Wind Energy
Wind energy is a renewable energy, unlike fossil fuels it’s free and clean (European Wind Energy Association, 2010) that is generated by converting kinetic energy in wind currents into mechanical power. The kinetic energy in the air flow provides force that turns the blades inserted on top of the turbine. A drive shaft provide the mechanical energy to power the generator in the turbine. The place wh...

... which can affect the nature environment and also wild life, figure 6.
In conclusion wind energy should be used to generate 100% of the state electricity. It is carbon free, it does not emit greenhouse gases in the atmosphere, which harm the environment and even the human respiratory system. Although residents say they cause noise pollution, engineers are working on technological advancements to improve the issue. Furthermore, they provide employment opportunities for the local community, it helps to support the economy. In addition to that, wind power produced can be sold to other countries with electricity shortages, this improves relationships and connections on a global scale. A recommendation that could be taken into account in the future is that, all wind energy companies or projects should consider the impacts wind before decisions are made.

- Wind energy or wind power is the extraction of kinetic energy from wind and the conversion of it into mechanical energy. Man has harnessed the power of the wind for many centuries. Wind is a type of solar energy. The sun heats the earth’s surface and the warmer air begins to rise. Cooler air flows into the area below the rising air causing wind. The Egyptians utilized the wind as early as 5000 B.C. by attaching sails to propel boats across the Nile River. For many years sailing ships on the open seas were powered by capturing the wind with sails.... [tags: Kinetic Energy, Mechanical Energy]

- Remember in Wizard of Oz how Dorothy was swept away by a tornado, and how tornados are massive wind storms. Well, it is no wonder they took the setting in Kansas. “Kansas has been ranked third in the nation for its potential wind resources” (Wind Power and Wildlife Issues in Kansas). Wind turbines have been placed all around Kansas, gathering wind to produce energy. Truth is it’s causing problems for animals and farmers. A great deal of biodiversity is being taken place throughout the wildlife. Unhappy farmers complain about their land space and the effects it has on their farms....

- INTRODUCTION Wind energy is gaining popularity throughout the world. Due to growing importance of wind energy, the rapid development of wind energy technology has a large involvement of people and institutions. Wind power is increasingly being viewed as the mainstream of electric power supply due to: zero emission of harmful gases ,significantly economically exploitable resource potential , no cost uncertainties from fuel supply price fluctuations, modular and rapid installation opportunities for industrial rural and economic development, which majorly constitute its benefits....

- Solar and wind energies are under the category of renewable energy, in which energy comes from an inexhaustible source when used. Solar energy is produced using solar panels that capture the rays of the sun and convert them, through photovoltaic generation, into electrical energy (Hinrichs, 377-378). To make things short, the photovoltaic generations happens with the help the photoelectric effect, in which electrons and holes are produced when light shines on the negative plate of a solar panel (Hinrichs, 378)....

- ... At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor. (renewableenergy.com) Wind power has become affordable enough to compete with fossil fuels. Around the world utility services are offering wind-generated electricity at a premium of 2 to 3 cents per kWh. A household that uses wind power for a quarter of its electrical needs, the cost would only be $4 or $5 dollars per month for it and the price is still dropping....

- One of the fastest growing and most promising renewable energy source within the United States is wind power. The most prevalent form of wind power generation comes from large fields containing numerous elevated turbines (Fthenakis). These fields are known as wind farms and are connected directly to electric power systems. Using turbines to harness the wind offers the United States, as well as the world, an opportunity to generate huge amounts of energy in a clean process that has little to no negative effects on the environment....

- The IEA’s research confirms that onshore wind energy is well on its way to overpower the installed cost of coal. Still, the installed cost of nuclear remains in competition with offshore wind energy. Looking further into the graph, offshore wind energy is steady in its growth. Wind energy made tremendous progress in its growth overseas, like the largest wind farm by capacity based in China, yet the United States is experiencing big breakthroughs in the percentage of generated electricity throughout the states....

- The nuclear energy debate has persisted for decades. Those who strongly oppose it argue that its benefits, such as carbon-free emissions and low fuel costs, are almost irrelevant when the risk posed by radioactive waste and reactor meltdowns are factored in. The problem revolves around how little waste storage is prioritized in the planning stages of a reactor, including the locations of waste storage, leading to a surplus of radioactive waste at reactor sites. With the progress being made to advance waste disposal methods and increase public participation in countries that need storage for accumulating waste and developing countries considering nuclear energy, nuclear energy could...

- ... ρ = The air density (1.2kg/m³ at sea level and 20° C) A = The swept area of the turbine blades (m² square meters) V = wind speed (meters per second) (Wind Turbine Kits and Supplies, windgenkits.com) Let’s test this equation out. Let’s say we have a pretty nice wind turbine at Sachse High School. Built and organized by the highest authority, Mrs. Marsh herself. The swept area of the wind turbine is A=15ft² = 1.5m². The wind speed is at 15mph = 6.7m/sec. The wind power at 15mph is: P=1/2 (1.5) (1.5) (6.7) ³ = 338 Watts.... [tags: natural wind, windmill]
