...Research Paper: Destruction of Birds by Windmills Birds are likely to be affected and/or destroyed by windmills, this is a natural part of life. The basic cycle is, wind developments tend to be placed in upland areas with strong wind currents that have a lot of potential to generate energy. Birds use these currents as highways, so they are likely to come into contact with the windmills (aka turbines). Windmills pose one the highest risks in the world of killing birds. Research also indicates that wind developments can disrupt migration routes; while bird's foraging and nesting habitat are at risk of being lost when turbines are put up. Windmills don't affect all birds, but they do affect birds of prey, disproportionately. The main reason this occurs has to do with bird's genetics. For example, species like vultures have blind spots in their visual field. This means they cannot see objects directly in front of them (like wind turbines) when flying. Concerning amounts of bird deaths; large birds like hen harriers, eagles and vultures are slower to reproduce than other species, so their populations are more likely to have a small number of deaths. Unfortunately, there are specific locations in the world where windmills have caused a great number of fatalities amongst birds of prey. In the Almont pass in California, one study found that about 4,000 wind turbines killed 67 golden eagles and 1,127 birds of prey in a year. In Southern Spain, 252 wind turbines located in an area used...

...developed a radically new windmill in her garage that she hoped would reduce energy costs for farmers in regions where high winds were common. Based upon her estimates, two of these windmills, together with a storage battery system, would be capable of supplying the normal electrical energy requirements for an average farm. To date, Urs had received a patent for her "Big Wind" windmill system and had sought some advice of professional colleagues as to the best way to market, make, distribute, and service the windmills for potential customers. Urs calculated that at a selling price of $16,000, she could net $4,000 per sale after paying for materials and labour for two windmills, a storage battery system, transportation and installation that would be required for each windmill system sale. An average farmer could expect to save enough on his electricity charges to recover the cost of the equipment within eight years, according to Urs estimates. Based upon feedback she received attending a wind-energy conference, Urs believed her windmill could have long-term potential and be made even more efficient with further research and through the use of improved battery systems currently being developed by other companies. Maintenance for the complete system, over the eight-year payback period, including battery cell replacement, was estimated to cost about $1,500, which was about half the cost for comparable windmills used in Europe. Development of the windmills had already cost Urs...

...and why are they not addressed: According to the author, if there is a conflict between one or more parties and one of the parties is management, who is not willing to convey the problem or resolve the conflict. Such kinds of conflicts are suppressed conflicts. Few reasons for not addressing may be due to avoidance, tolerance, Employees fear of escalating conflict, Employee thinks that there may not be any change and they also fear of reactions from their manager. In Case Study "Cape Trafalgar" parties involved in the conflict are fishermen and two companies willing to build huge windmills at the sea shore. Suppressed conflict is on construction of windmills. These companies never involved in discussion or considered the concerns of fishermen and when fishermen approached many officials to express their concerns, they didn’t communicate back to them. Manuel Bustos is one of the officials for windmill production, he never resolved the basic issues of fishermen and he stated to his group to influence the fishermen by telling benefit of the project. In our case fishermen are ready, but government and wind organizations are still discussing and not cooperative to surface conflict. Problems occur if such situations are ignored: If the situations are ignored, it may turn even worse and employees refuse to work, poor coordination and integration. Employees become demotivated and in turn loss to the company since cost factor increases with these situations, there is will be no creativity...

...using the natural resource that is wind to rotate three blades that are used to run a generator stored at the top of the turbine. In this report the location of wind farms will be discussed and their advantages and disadvantages. Also the installation of both on and offshore turbines will be examined. In addition Ireland and the need for wind farms will be investigated in greater detail. Figure (1.1) Windmills In an open space unhindered by earth’s natural formations such as mountains. 1.2 History Wind was undoubtedly an indispensible resource from the beginning of civilisation. Wind was the natural resource that powered ships which made trading possible due to transportation of produce on water. Wind was also used to power grain mills which were used to grind wheat and corn. Irrigation was made possible on farms by using windmills to pump water to areas of land that had no natural access to water. Wind mills were also used to power big Saws that were used for cutting wood! The first known windmill dates back to the ninth century and was in Persia. The first windmill designed was by Daniel Halladay In 1854 in New England. Figure (1.2) Wind harnessed to crush grains with a cob grinder. 2.0...

...and distant future. There are many advantages to wind energy; it is a sustainable energy source that is non-polluting. With a 30 percent annual increase, wind is the world’s fastest-growing bulk power electricity source. Montana has a bright future in wind energy. The American Wind Energy Association ranked Montana’s wind-energy potential in the top five in the nation. Currently, the state has several utility-scale wind farms in operation. History of Wind Energy Wind energy has been used by civilizations throughout time. As early as 5000 B.C., wind energy propelled boats up and down rivers. Simple windmills pumped water in China in 200 B.C. Wind energy technology and its applications continued to grow and diversify throughout the ages. By the late 19th century, settlers of the New World were using windmills to pump water, and eventually, to generate electricity. Small windmills were used until the late 1920s to bring electricity to rural Americans. Farm and ranch communities in Montana used wind generators that produced direct current (DC) electricity that was often stored in batteries. However, these systems were short-lived due to the Rural Electrification Act (REA) of 1936. The REA subsidized the construction of rural electric distribution lines, transmission lines, and electrical generation facilities through low interest loans. This government act dramatically increased the number of rural Montana communities that received grid-connected electrical service. The energy...

...The final topic I choose is wind energy; about is it clean cheap and practical? As people know that wind energy is totally clean and just use wind to convert energy. I will figure out what is the advantage of wind energy and how to get the clean, environmental wind energy. However, people don't know how to gain wind energy; the process of converting is clean or not. Furthermore, what kind of machine like windmill can make wind energy, that’s also a question. First, I will introduce the wind energy which has different types, and their different function. Using the official language in the google to describe it, also when and why wind energy comes out. Like talking about wind energy’s history. And I will tell the wind energy machine, how to make it and how long to make it. also, how much pollution it will have during the making time. Then, I will say something about how wind energy developed and figure some celebrity in this area and their contributions. And what they didn't do and the difficult points for them and future wind energy. The next step I will talk about the wind energy in worldwide, how it works and what range does it works, then specify to different countries, such as the U.S. and China. And the result and how wind energy works efficiently in those countries. For the detail of those information, I will use website or database in library. At last, I suppose to say that the advantage and disadvantage of the wind energy. Also, compare what wind energy can...

...What are the explicit and implicit costs of the policy proposal to use tougher controls/standards for environmental improvement to your concern and explain the implicit and explicit costs involved? Answer The best valuation technique to use to prevent global warming would be the use of wind energy. I believe the use of the windmill will be a good measure and will quickly improve the environment. The cost of operating wind energy is more expensive, but I think our environment is well worth the cost. Some drawbacks of wind energy include, noise disturbances which all though wind energy are non-polluting, and the windmills may create some amount of noise when it’s turning. Wildlife can also be threatened due to large scale construction of wind turbines in remote locations, so it could cause a threat to wild life. The main disadvantage of wind energy is that wind can never be predicted. In areas where large amount of wind is needed or winds strength is too low to support wind turbine, there solar or geothermal energy could prove to be great alternatives (Conserve-Energy-Future, 2014). However these issues could be reduced, by the location in which he windmills are installed. If they are...

... June 6, 2016 Sec 1 Prof. Pelias Reflection: We visited 5 places in our Viaje de Angono. We depart from Santolan Station by roughly 8 am. The travel time to reach our first destination which is the Rizal windmill is 2 hours, as far as I remember. I have not been to Ilocos Norte to witness the famous Bangui Windmills, and it is included my bucket list to have a picture with those. I was really amazed to see the wind farm in Rizal since it seems like I get to see those in Ilocos. I also found out that the same company is operating both the Bangui and Pililla windmills. The Pililla windmills are on top of the hills overlooking the beautiful plains of Tanay Rizal on one side and Laguna on the other side. One will also get a very good view of Laguna de Bay. There are infographic boards there about Pililia and the wind farm. One interesting fact on why Pililia was chosen as the site for these wind turbines –these hills have a natural wind corridor with a monthly average of 36kmh windspeed passing through the hill and heightens during Amihan (north-east winds) season from October to March. We took plenty of photos with the wind mills for remembrance. Also, we bought memorabilia that the residents are selling there. We had our lunch after windmills. Then, we went to Nemiranda Art Haus and Balaw-balaw restaurant. This arthouse is surrounded by mythical relief murals and three dimensional mythological characters such as the “Ang Nuno” , “Habagat” and “Bernardo Carpio”...

...Electricity has occupied in every corners of our lives. It can be clearly seen that cooking, working and entertaining directly or indirectly involve using electricity. People are slowly turning from fire as the source of heat to electric device that has capability to produce heat. Nevertheless, the growth of using electricity has pushed the world into energy crisis where demand is surpassing supply. In order to solve the issue, people must cut short electricity use and increase power input. It means that devices should be off when they are not in use, replace obsolete bulbs with energy efficient bulbs and at the same time build more energy harvest systems to enhance electricity production. Electrical energy can be produced by renewable sources and non-renewable sources of energy. With development in the technological field, renewable resources like water, solar, and wind current are preferred to produce electricity in order to replace fossil fuel which would not last very long. In fact, natural resources can produce multi-folds of electricity without being eradicated. However, this essay is comparing solar panel to wind turbine. Their major differences are location, method and efficiency. Initially, the difference of both solar panel and wind turbine is method of generating electricity. Since the solar panel has defined as an object that absorbed the sunlight and turns it into electricity. The method to generate electricity by solar panel is complex. Firstly, after the sunlight...

...Wind Turbine San Jose State University, Charles W. Davidson College of Engineering E10 Introduction to Engineering By Justin DeCastro, Cari Geldreich, Hugo Quiroz, and Ashley Mishra March 24, 2011 Professor Athanasiou Section 6 Project Summary The project that was assigned in lab was the wind turbine lab. The objective of this lab was to develop and construct a wind turbine that would create enough energy to conduct electricity. The goal of the assignment was to construct the most creative and stable structure so that it would withstand high winds. After constructing the turbine, which was 17 inches high and weight 255 grams, the next task was to test its stiffness using various amounts of weights and to look for the displacement. The maximum amount of displacement by the turbine was 4.81 mm. After finding out how stiff the turbine was, the next task was to measure the amount of power the turbine generated. The turbine worked quite well except for the fact that the blade broke within the first few minutes. The blade speed started out with 9703 RPM and went down to as low as 6000RPM when it had 6 light bulbs on. The turbine successfully completed all the objectives with ease. The only thing that it could’ve done better in was the stiffness test because it displaced more weight than it needed to.

...The reading and listening are discussing the topic of wind energy. The reading starts out by mentioning the wind is good and it is a renewable resource. The wind is available everywhere. In United States, 20 percent of the electricity could be provided by wind power. However, the speaker argues by mentioning the amount of energy produced by wind power, it is unpredictable because it can spread out. Wind power does not generate if wind is not strong enough. Moreover, not everywhere that turbine for generator can be installed. The reading continues by bringing up the point of the cost of wind energy. Wind energy is affordable compare to coal, oil, and gas because the wind is free. Alternatively, the speaker once again resists this idea by the initial investment for produce wind energy is expensive. A generator for produce wind energy needs location and land that big enough for a machine. Land is very expensive and hard to find. Furthermore, a generator will be built in a farm far from the city. It needs to build a transmission line to transfer the energy from farm to city. These can cost a large amount of money. The final point made by the reading is wind power is safe and environmentally friendly. The wind energy does not cause greenhouse gases or other pollutants. Comparing to other source of fuel such as coal, oil, and gases, wind is cleaner. So, it helps reduce causes of global warming and it will lead to better health of populations. Whereas, the speaker says that wind energy...
