...Power by the Wind 1 Power by the Wind Power by the Wind covers the topic of wind energy. There is a large sector in our country that believes wind energy is an excellent alternative resource, including myself. There is also a group of people that believe that the wind turbines that are used to generate wind energy is a bad idea because they obstruct the natural view, causes death to birds, and generates noise pollution. They also argue that wind energy is not a dependable source of energy because the wind does not blow continually. I will explain the long history of wind energy and the methods that have been used to harness it. I will also look at wind energy from a positive and negative perspective. A Long History: The human relationship with the wind has been a long one with the use of sailing ships and windmills. For centuries past the wind was used as the main power source for sailing ships. The use of windmills seems to have started with the Persians for grinding grain (between 500 and 900 A.D.). Windmills started appearing in Europe around the time of the Crusades (1096 -1270). The European design is very different from the Persian one Power by the Wind 2 and there is an ongoing debate whether the Europeans developed the windmill themselves or the Crusaders had taken the idea back to Europe. The earliest windmills found in Europe were a post mill construction. The main structure of the windmill sits on top of a post and...

...Knowledge of Wind Turbines The purpose of this presentation is to inform the audience about general information on wind energy. I want to inform the audience of the basic design of a wind plant. I will also introduce them to the basics of wind turbines and what a wind turbine site consists of. The best audience for this presentation is anyone without previous knowledge of wind turbines. This presentation is designed to generally educated people on wind turbines and wind sites. It is not designed to go into real depth with wind turbines. If there was anyone interested in getting wind turbines on their land this presentation would help to let them know what to expect. They type of audience that would resist this knowledge is any group that works in fossil fuels. These communities usually worry that their jobs our in jeopardy because of green energy. This topic is important because of the increase in wind turbines throughout the United States and world. It is important for us to understand the basics of what they do and what a plant is made up. The reason this is important is because we the people vote to allow turbines in our communities. The more information we have on the technology the better decision people can make for their communities. Research shows that due to better technology and the demand for green energy Wind Turbine development is increasing across the United States. Today I’m going to give a brief back ground of the history of turbines...

...Out of one hundred percent, wind energy is responsible for giving four percent of the American population electricity. The atmosphere is not going to get better on its own so we must take action from moving from burning fossil fuels to renewable energy like wind energy. Although it would be a very slow process, the atmosphere and the wallets of every American family would benefit from the change. Wind energy, unlike fossil fuels, is available through wind turbines. These tall towers with huge blades move in a circular motion where they capture wind in between the blades. The blades in a turbine are connected to a shaft inside and this only has 18 rpm (rotation per minute), which is nowhere near enough to create electricity for homes. So because of this the shaft is connected to a series of gears that roughly has 1800 rotations per minute. With the gears moving 1800 times a minute this creates electricity, which is transmitted to a generator. From there, the turbine is connected to a transformer, which increases the voltage of the electricity in order for it to flow through the transmission lines. Once the electricity reaches the transmission lines the energy flows to the grids of electric companies and are able to provide houses with cheaper electricity. A single small wind farm is able to create enough energy for roughly 900 homes. Wind power is nothing new. It has been around ever since the first windmill was made. “Since early recorded history, people have been harnessing...

...Green Wind Energy All we hear about anymore is green this and green that along with what are you doing to contribute to the green way of living? What changes have you made in your daily life to ensure the future of our earth? A lot of information and talk centers on our energy generating techniques and safer ways it can be done without the use of fossil fuels. One of them being the use of wind energy, harness the air that it already moving around without causing anymore damage to our earth. Sounds like a reasonable request but what does it all entail… Lets do some research into how long this idea has been used and the different approaches that have been taken to make it happen. Wind is caused by sunlight unevenly heating the surface of the Earth. During the day, air over the land heats up more quickly than air over water, making it expand and rise. As it does so, cooler, denser air rushes in beneath it, creating an air current. Some giant wind currents are drive by hot air at the equator and cool air at the poles (Aldred, 2007). I was surprised to find that wind energy sources have been around since the tenth century in Persia and the thirteenth century in China. The uses focused on windmills with the grinding of grain, pumping of water and sailboats. Windmills and water mills were the largest power sources before the invention of the steam engine. The main long-term use of wind (except for sailing) has been to pump water for the irrigation of fields (Nelson, 2013,). The...

...Airplane About one hundred years ago the planet earth was a much smaller place. On December 17, 1903 the Wright brothers, Wilbur and Orville, made history when they took off in flight and invented the first airplane. This is how the planet earth began shrinking geographically making it easier and quicker to travel over long distances. Wilbur was the older of the two brothers by four years. Wilbur was born in 1867 on a farm near Millville, Indiana and Orville was born in 1871 near Dayton, Indiana. As youngsters, Wilbur and Orville looked to their mother for mechanical expertise and their father for intellectual challenge. Milton, their father, brought them various souvenirs and trinkets he found during his travels for the church. One such trinket, a toy helicopter-like top, sparked the boys' interest in flying. In school, Wilbur excelled, and would have graduated from high school if his family had not moved during his senior year. A skating accident and his mother's illness and subsequent death kept him from attending college. Orville was an average student, known for his mischievous behavior. He quit school before his senior year to start a printing business. The two brothers were very intellectual and smart, but both did not ever get their high school diplomas. It just goes to show that even two of the best minds in our history didn’t have to go to college or even finish high school to become these great minds. The first time Wilbur and Orville referred to themselves as...

...Catherine Drake Instructor Minor July 27th 2013 Green technology what is it, Where does it come from and how do we use it? I am hoping to answer these questions to the best of my ability. “The green movement evolved considerably since the early days. Since there are some popular assumptions about environmental history that are incorrect.” (A brief history of the modern Green movement in America, WEB ECoist). The green movement can be dated back to the 19th century possibly even as far back as 1830. Back then it was called “Environmental movement.” Since this time Green technology has been referred to as environmental wako’s, tree huggers, and many more unfriendly names, however what they failed to see was what these green technology people were doing was helping the environment and the way we live our daily lives. The green movement started with Americans thinking that we should cultivate land instead of leaving it alone to be wild and free. This was a big clash between Native Americans and Americans. This soon would be forgotten until after World War II and the 1948 disaster at Donora (called the Death Fog) that prompted a national outcry. (A brief history of the modern green movement in America; Web Ecoist). Green technology took a more personal issue in the green movement, such as the issues we more centered on food safety and consumer goods. In the late 60s early 70s is when we started to see a rise in the modern green movement. Closer to the 70s is when more steps...

...Winds of Change Sonya Marquis BUS440-801 Introduction Wind energy is a renewable resource, which means that future supply will not be affected by current use. The rising concerns about global warming, pollution, and depletion of natural resources makes wind a viable and logical source of energy for the near 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...

...energy in 1767. We have come a long way since then in the various applications that we use the Sun’s energy for in today’s world. In 2012 the people of India built one of the world’s largest applications of using the Sun’s energy and transforming it into electrical energy. The Gujarat Solar Park is a collection of solar farms scattered around the Gujarat region, boasting a combined installed capacity of 605 megawatts of power that is completely harnessed from the Sun’s rays. Advancements in solar technology are being made every day. Researchers from the University of Illinois at Urbana-Champaign and the University of Central Florida in Orlando may be one step closer to tapping into the full potential of solar cells. The team found a way to create large sheets of nanotextured, silicon micro-cell arrays that hold the promise of making solar cells lightweight, more efficient, bendable and easy to mass produce. Which is just one example of how bright the future of solar technology really is. Another energy technology that has been used for centuries is the Wind. Wind energy has been used to sail boats along the Nile River as early as 5000 B.C. and in...

...and Inexhaustible Energy Sources: Wind Power For over two thousand years, mankind has harnessed the wind for power in one way or another. The first uses were for water travel, by letting manufactured sails catch the wind and allow the boats or vessels to travel seamlessly across the water. Eventually, it was realized that the wind all around the world will not run out, it is a semi-constant force. Therefore, wind started to be used to power other things; mainly for farms and small workshops, wind power was harnessed using the old-fashioned windmill. They were primarily used to pump water from wells, and some to grind grains down to a fine consistency. Today, there are many other uses for wind power. As an ever-growing society, we have realized that the resources we rely on day to day will not always be around, i.e. oil, so we have harnessed wind power to our advantage, because like our early ancestors also realized, the forces of wind will never be depleted. With the widespread development of electric power in the early 20th century, wind power found new applications in sending power remotely from a centrally-generated power source. Throughout the century, small wind plants suitable for farms or residences were soon built, and also larger utility-scale wind generators were produced so they could be connected to electricity grids for a greater remote use of power. Out here in West Texas, we rely heavily on wind powers because the wind is an abundant force of nature to us...

...discussing the early history of Ming China, there’s one historical figure that must be mentioned, and that man was Zheng He. He was a great Chinese commander for Emperor Yongle. Zheng He was sent on a series of seven voyages, sailing all over the Southeast Asia and the Indian Ocean world. He and his enormous fleet navigated to many different countries, and for this reason historians believe that the purpose of his voyages were exploration and that he was an explorer. Historians also debate whether or not Zheng He’s expeditions were imperialistic. However, Dreyer argues that Zheng He was not an explorer and the purpose of his voyages were not imperialistic. The main purpose of Zheng He’s voyages was to project the wealth and the power of...

...down. When this was to happen the winds picked up and caused all the topsoil to go with it causing massive clouds of sand. This Dust Bowl was bad timing because around this time the Great Depression was happening. Another cause of the Dust Bowl was drought, the topsoil was now dry and loose, any wind could pick up and bring the dirt with it. Many farmers were forced to migrate because of all the sand covering everything leaving them with nothing. The Dust Bowl lasted for about a decade it started in the 1930 s and did not end until 1940. This disaster is not natural it was a man made disaster. Farmers ripped up all the roots and grasses holding that soil to plant things,then later did not plant anything due to costs.Then the Great Depression hit and farmers could not pay their loans or keep their farming equipment. The farmers could not pay for equipment they needed which lead to the soil being bare.”The region’s exposed topsoil, robbed of the anchoring, water-retaining roots of its native grasses, was carried off by heavy spring winds.”(Cited from: "Dust Bowl."
