...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...

...Is Wind Power Green? Is the future of green energy written in the wind? This is the question of many researchers and scientists alike, who want to move our planet into a more greener state of existence. There are many alternatives to creating energy, according to leading future technological experts. These same experts claim that, "Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists" (Bergeron, 2009). Almost all of the research put into this topic leads to the fact that it is the right thing to do and that it is what's best for our world. Experts are all for a clean energy source and the move of our world away from depending upon fossil fuels. The question is not, "why do we want or need to move to clean energy?" It is, "How are we going to do it with the smallest footprint as possible?" The answer to wind power being green is very clear, it is clean and can be used as a major key player in getting the planet off of fossil fuels. Politics, money-loss, and loss of jobs could be the outcome of converting all of our energy source from fossil fuels to wind. While this is scare and absolute change is going to have to occur, there are very hard facts that are going to have to be considered, if the planet was to flip over to more natural energy sources, like Wind Power. "Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand"...

...areas of the world, one can see the beauty of wind power being harnessed by the wind turbines that line the fields. When thinking about renewable alternative energy and places that are successfully incorporating the energy into daily lives, Texas immediately came to mind. Texas is ranked number one in the nation for wind energy capacity (Texas wide open for business, 2014). If one were to look at Texas as a country, it would rank number 6 on a global scale for installed wind energy capacity (Texas wide open for business, 2014). Wind turbines are used to generate electricity from wind. What is interesting about wind energy is that it is a form of solar energy, caused by the uneven heating of the atmosphere by the sun (Wind Energy Development, n.d.). There are advantages and disadvantages to wind energy. First to discuss a few advantages. Wind energy is friendly to the environment and does not use fossil fuels while generating electricity from wind energy (Clean Energy Ideas, 2007-2015). Turbines are a great way to generate energy in remote location and they can be different sizes to support different population sizes (Clean Energy Ideas, 2007-2015). When wind power is combined with solar electricity it is great for developed and developing countries in providing a steady, reliable supply of electricity (Clean Energy Ideas, 2007-2015). Finally, wind is free, and new technologies are making this more efficient to harness wind power (Clean Energy Ideas, 2007-2015). Next, to discuss...

...energy in the near future, like wind power or solar power. These changes would also help reduce the amounts of greenhouse (A gas in the atmosphere that absorbs and emits radiation within the thermal infrared range) gasses being emitted into the air, which would help slow down the effects of global warming. Wind is air in motion (Casper), and wind power is a large percent of current energy produced. It can help reduced emitted greenhouse gasses and slow down the effects of global warming. The global wind energy potential is roughly five times current global electricity use (Flavin). Also the price of wind generated energy fell more steeply than any other energy source over the past 30 years (Burnett). The cost of wind power fell from approximately 25 cents per kilowatt per hour (kwh) in the early 1980s to between 5 cents and 7 cents per kwh (Burnett). Advocates argue that a new generation of turbines will bring down the cost to below 5 cents per kwh (Burnett). This would make it much easier for people to be able to afford it. Wind power could provide as much as 6 percent of the nation’s energy (Burnett). It is currently providing less than 1% of the U.S. power supply but could double its shares within 10 years (Burnett). Furthermore, wind power plants receive accelerated depreciation (Burnett). As of 2006, wind power was the cheapest form of large scale electric generation to install (Lerner). This led to the growth of wind power plants. Wind power is the earliest form of energy...

...Wind Power in Global Community The energy obtained from the wind power is renewable and it could preserve and extend the uses of the exhaustible sources of energy like oil, natural gas, coal and uranium for other purposes. “Free input and cheap output” technology could be beneficial to many countries. Currently, five countries – Germany, USA, Denmark, India and Spain – concentrate more than 83% of worldwide wind energy capacity in their countries. The utilization of this renewable source of power is fast spreading to other areas of the world 1. And I want to take as example my company (Siemens Wind Power) where I am currently working. We have the offices in China, India, USA and Europe and run a lot of projects in the rest of the world. So, for us it is extremely important to have skilled and qualified managers to deliver our projects on time. Such a powerful source of technologies like an Internet and telecommunications gives us the opportunities to manage people without visual contact with them. As a part of Retrofit&Support team I am working with issues related to a personal safety through our system called KRIMA or NCR. Here our service people describe the warranty cases and upload relevant pictures. All I need is to have the access to the system, search for the report number and find a solution – design a new part or redesign of existing one. Even if solution is found I have to send it to my colleagues in India for simulation and further analysis. Meanwhile,...

...Wind Power as an Alternative Energy Source Although fossil fuels drive our economy, it is rather expensive and significantly contributes to pollution (Lad 2). A few alternatives include hydroelectricity, solar energy, and wind. Solar and hydroelectric energy are good choices, but can be relatively costly (“Top 5 Misconceptions of Solar Energy” 5), (“Hydro Electricity”). Wind, on the other hand, is free and available in most areas. However, wind power has not been fully utilized in the United States. The purpose of this paper is to give an overview of wind power in order to bring to light its usefulness as an alternative energy solution. Uses Wind power can be used to generate electricity, charge batteries, grind grain, etc. (Deshmukh 3). Turbines can be used alone or on a wind farm and can also be connected to a utility power grid to sell electricity back to the power company. According to the literature, wind technologies are most useful in the Midwest and along the coast. Pros and Cons Although wind turbines can kill birds and be damaged in severe storms (Deshmukh 11), wind turbines can provide many advantages. For example, wind turbines can harness the power of the wind, producing electricity, charging batteries, etc. Unlike fossil fuels, wind power consumes no fuel, and emits no air pollution. In addition, wind can be accessible in nearly all areas. Types There are several types of wind turbines, each having its own set of advantages and disadvantages...

...WIND POWER, THE REAL ANSWER TO OUR ENGERY PROBLEM? I believe that while the benefits are great the power companies and big businesses who produce fossil fuel energy will not allow us to replace it with wind or other total green forms of energy. It is said that electricity made from wind power can help to save our planet from the environmental effects of energy made by fossil fuels. It does work effectively and can reduce carbon dioxide (CO2) emissions to and using just one wind turbine can prevent around 5,000 tons of CO2 being put into the atmosphere a year. Wind energy produces little to air pollution or greenhouse gases, and is a very efficient form of energy but it does have its downfalls. “It is ironic that we think of wind, solar, geothermal, and other energy sources as "alternative" energy resources. If we look at energy from an historical perspective, wind and solar energy uses date back thousands of years, while coal and refined petroleum are more recent”(Deal, W. F. (2010, September). Wind mills were early wind turbines are believed to have started in the Middle East and were used for grinding corn or grain. In the United States Wind mills were used in the 1800’s in the Midwest to pump water for farms to water animals and irrigate crops. In the mid 1900’s windmills were used to generate small amounts of electricity to power batteries. As power lines were put in most of the windmills were destroyed. Wind power farms start popping up in the 1980’s and were predominate...

...The types of energy are wind power, solar power, geothermal power, hydroelectric power, and nuclear energy. In the next paragraphs, I’m going to explain the reasons why the world needs alternative energy and how the energy is harnessed. First type of alternative energy is wind power. Using large blades can capture the winds power. The wind causes the blade to rotate turning into electrical current. Electric generators harness all the energy and distribute it to small towns or larger scale towns. There are some advantages for using wind power. First, it causes no pollution. Meaning there are no harmful by-products. Keeping the world safe. Second, wind power is a renewable source; we will never run out of wind. Third, wind turbines can be placed practically anywhere. All you need is a good source of wind. As with any energy source, there are always some concerns. One concern is that wind is never constant. Some days there is significant amount of wind. Then the next day no wind at all. Another concern is that residents that live next to turbine blades think they are ugly. Second type of alternative energy is solar power. This is created by capturing the sun’s rays into solar cells also known as solar panels. The captured sunlight is charged into electricity. Solar energy is the most common used source. The majorities of the people have solar panels on there home, or planning to purchase some. Buying solar panels can save you money in the end. Solar power has some advantages as...
