Introductory Information

What we want to find out is that does the angle of blades on a wind turbine affects how much energy is going to be produced. The reason we feel that we that this would be a good topic to research is because wind turbines are starting to become more and more popular. Wind turbines have been used for many years for little and big things? They have been used on small farms and recently they have also been used on many large wind farms. They can vary in size depending on how much energy you need to produce. Depending on the size they can’t be too close because they can be very loud. The type of blade is also crucial to how the windmill will work. There are many different types of blades. For example: wood, metal, fiberglass and more. How many blades that are on the wind turbine will also affect how much energy the turbine will produce. There can be one to three blades. The way that the blades face is also another factor. The blades can be (as most people see them) on a horizontal axis, or (as most people don’t see them) on a vertical axis.

Once again we want to find out is that dose the angle of blades on a wind turbine affects how much energy is going to be produced. On a wind turbine the angle of a blade needs to be precise so that they can get the maximum amount of energy that can be given. We would like to know which angle on the blade of a windmill is perfect so people can get maximum efficiency out of the wind turbine.

Background Information
Some important history that you might not know is that wind turbine have been around for hundreds of years to be exact the first known windmill was made by a greek engineer named Heron of Alexandria in the first century AD. However the first practical wind turbines had sails that rotated in a horizontal fashion . This was invented in eastern Persia but was recorded by the Persian geographer Estakhri in the 9th century. they were first used to mill grain and water pumps. Some history

    However, when wind speed is greater than 12 miles per hour, can generate 70 % more electricity, and the best approach to ensure such scenario is building platforms for the fans at higher altitudes (Green living, 2013). In case wind increases too much, it can damage the wind turbines, therefore most of the wind turbines automatically shut down when wind speed is greater than 25 miles per hour (Green living, 2013).…

    The journey to find an alternate source of energy that is in accordance with past events and current trends in technology has introduced new methods for human beings to care for the environment and to protect earth’s natural resources. An alternate source of energy that this paper will be covering is wind power. This is not a new discovery but overtime it took a fresh and better tactic. History will reveal that hundreds of years ago, windmills were already use in Europe in wind farms with wind turbines in order to gain as much as wind energy as possible. This is an effective method in producing the maximum wind energy; however, there are pros and cons that one has to be aware with in this kind of alternative source of energy.…

    Wind being used as a source of energy isn't new as it has been used ever since the invention of windmills and boats. Due to the fact that fossil fuels are the primary source of energy in the United States (along with other countries), people have begun to look for other ways to get our energy. Though this topic relating to the energy issues always bring up controversy, in this essay I will tell you the two opposing views on wind farms and then tell you which viewpoint I agree with and why. Then, you will be able to form your own opinion on this issue.…

    Wind turbines generate electricity through this process: the wind turns the blades which then spins a shaft. The shaft connects to a generator which produces electricity. The UK is an ideal place for wind turbines because we are one of the windiest nations in Europe. Cumbria in particular is an ideal place to build new wind farms because it is a very hilly area and it has a long coastline; making the area very windy. There is already a wind farm in the village of Great Orton and so far it has been a success. It has supplied 2,000 homes and has saved about 8,530 tonnes/year of greenhouse gases. It also gives farmers extra income in the area because the wind farms are built on their land.…

    On the environmental aspect, wind energy does not contribute to pollution as almost no waste materials that contribute to pollution are produced by the usage of wind power (Wright, 2005). For example, in the States, wind plants compensate the emission of than 2.5 billion pounds of carbon dioxide and 15 million pounds of other pollutants (Nash, 2008). This shows that wind power is an eco-friendly renewable energy resource as it does not contribute to pollution.…

    For many years, people have been harnessing the power of wind. Wind propelled boats down water and simple windmills were used to pump water and grind grain. But credit goes to the Dutch who refined windmills so that they could drain swamps and lakes, and in the 19th century, settlers took this concept with them to the New World. There, windmills were used to pump water for farms and ranches, and later to generate electricity for homes and industry purposes. Industrialization caused a decrease in the use of wind power, but also began the development of larger windmills to produce electricity. The result, commonly called wind turbines, could have been found in Denmark as early as the 1890s.…

    A few days ago, I was outside walking around the farm when I noticed a small knoll in the long pasture, not far from the farm buildings (35). I discovered that it was the highest point of the farm and thought to myself; ‘This would be the perfect place to build a windmill.’ The windmill will be used to generate electricity through a dynamo by using energy from the wind. I have learnt this information from the trusty books I have read so I can assure you that this project will not fail.…
