Wind turbines are an efficient way to produce energy for power and electricity. They’re built in range from 40m to 94m tall. The main components of a wind turbine are the tower, rotor, rotor blades, nacelle, gear box, generator, coupling, and break. It also contains components that follow wind direction, cooling, heating, and lighting protection. Wind turbines turn the wind’s kinetic energy, and turn the energy into mechanical power. Mechanical power can be used for other things like pumping water, but wind turbines turn the energy into electricity. It’s the most environmentally friendly way to produce electricity compared to nuclear or coal power. The question on my mind is if it’s an ethical issue. I’m sure there’s an issue in this. Wind turbines don’t make a big reduction on carbon emissions and it’s affecting the people around where wind turbines are being built negatively. Tall turbines ruin the landscape and produce a noise that can be extremely annoying and causes health and psychological problems within individuals who live around wind turbines which would be called the ‘wind turbine syndrome’ was made. Should we listen to individual people and stop building wind turbines because of potential harms to the individual, even though wind turbines are not contributing to worse environmental problems that can harm a larger majority of our human population from climate change?
One side of wind turbines are that the Wind turbine farms are located in areas where people live. Some people think wind turbines are visual pollutants. The wind is unpredictable and never really constant, therefore it’s not reliable source for energy. If the wind is not blowing, they will not generate power. Just like Solar panels, wind turbines are not c...

...bines are?”
A: “I think they’re efficient and energy saving in a way, but they're extremely annoying.”
“How are they annoying?”
A: “They produced this constant ongoing noise. I've lived there long enough to ignore it but some days When I needed some peace and quiet, Wind turbines completely ruined it.”
“There's also a problem with wind turbine casting on and off shadows. Does this happen to you?”
A: “No, I personally didn’t have that problem because of the way my house was positioned but I could imagine someone going through that.”
I've researched that Wind turbines are interfering with wild life and killing birds. What's your input?
A:” Matter a fact, I’ve see a dead bird here and there on the ground every once in a while as I think about. It’s crazy how something that supposed to be environmentally friendly is killing wild life.”
The rhetorical occasion of this excerpt is to inform others about the dangers of chemicals on earth’s vegetation and animal life.
By citing credible organizations and offering her own eco-friendly alternatives, she proves to the reader that she takes a particular interest in the environment and is educated to speak on it. Pairing powerful understatements and hyperboles to contrast with one another show the reader that the practice is both needless and selfish. These rhetorical techniques have a powerful impact on the reader, whose ignorance prior to reading the excerpt can no longer suffices to excuse the lack of action. Rachel Carson’s Silent Spring is a deeply persuasive book that not only advocates for an end to pesticides but also speaks to the obligation humans hold to protect their
Rachel Carson’s seminal 1962 book, Silent Spring, told the real-life story of how bird populations across the country were suffering as a result of the widespread application of the synthetic pesticide DDT (dichlorodiphenyltrichloroethane), which was being used widely to control mosquitoes and others insects. Carson reported that birds ingesting DDT tended to lay thin-shelled eggs which would in turn break prematurely in the nest, resulting in marked population declines. The problem drove bald eagles, our national symbol, not to mention peregrine falcons and other bird populations, to the brink of extinction, with populations plummeting more than 80 percent (Mildred, 2012).
"Two windmills", a simple poem by Geoffrey Dutton, which records the poet's memory, of living on a sheep ranch is his childhood. In depth he paints a vivid picture in the reader’s mind of the conditions in the Australian outback. This is portrayed through the use of visual and aural imagery.
Another example she uses to make her point is about coral. When thinking of coral, the idea that comes to most is it is a plant that lives in the ocean and provides a beautiful color. Coral provides more than that for the ocean as we see it provides “Thousands-perhaps millions- of species have evolved to rely on coral reefs, either directly for protection or food, or indirectly, to prey on those species that come seeking protection or food” (Kolbert 130). When carbon dioxide enters the ocean, it forms into an acid called carbonic acid, which has been eating away at most of the coral and not allowing it to grow or survive in the water. This other example used by the author showing humans how we are destroying important aspects to earth. We should be more alarmed to what is occurring in the ocean because we also depend on it for some of our resources. It also goes to show if we are capable of putting other animals in danger we are fully capable of erasing our own
With concern over global warming growing, people are starting to turn a more serious eye toward cleaner sources of energy. Instead of solar power making a comeback as the ideal form, we are seeing a growth in the use of wind power. Wind farms are beginning to crop up all around the country. This new trend has gathered significant attention. Questions are being raised concerning the effects wind farms may have, from critics and supporters alike. Michelle Nijhuis, in the article “Selling the Wind” discusses the arguments on behalf of and in opposition to the increasing use of wind power, addressing what the consequences may be on the United States.

In everyday life, there are things that one needs to survive. And sustainability problems arise every day. One such problem is energy loss. The world is using up a lot of energy and new ideas need to be formed to help the rest of the world and the future of the generations that are to follow, to survive. With that the problem is that people use up energy and they do not use it efficiently. Therefore scientists are needed to find ways to deal with the sustainability problem that is arising. That is where wind turbines are used to generate this energy but the actual wind-turbines are very large, loud and they kill birds, thus new designs need to be found in order to help energy usage and to bring the size and structure of the wind turbines to a smaller scale to prevent injuries to nature and the species around it.
Wind power is another form of solar power. Wind isn’t only a clean fuel source, but it is one of the most inexpensive e alternative sources of energy. Just as long wind continues to blow and the sun shines then wind power can produce energy to send to many different areas. There aren’t many locations that have continuous wind. And because of that the widespread development of wind power isn’t as great as it could be. Although there are more advantages than disadvantages when it comes to this energy source, the disadvantages should be taken just as seriously. Wind power can harm animals, there was a study that stated birds were coming in contact with turbines and dying. For many people the noise from the turbines is unbearable, and that’s something else that should be taken into
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
First and foremost, unlike power plants that rely on combustion of fossil fuels, wind turbines do not produce atmospheric emissions. Strangely enough, wind is a form of solar energy. Winds are caused by the irregular heating of the atmosphere by the sun, the variations of the earth 's surface, and rotation of the earth. This wind flow, or kinetic energy, when "harvested" by modern wind turbines, can be used to generate electricity. There is an abundance of wind to meet our needs, “the potential of [the total] wind power [in the world] is… 20 times more than what the entire human population needs” (Maehlum). Currently, wind power is one of the lowest-priced renewable energy technologies available, costing between four and six cents per kilowatt-hour, depending upon the wind
Each one of us has their own opinion about what wind turbines do and not what they are actually meant for. Wind turbines are meant to be an energy saving method that can be used ...
Although renewable energy can be expensive to build, it has less environmental damages in comparison to non-renewable energy. Besides the natural resources such as sun, wind, water and hydrogen, we also have geothermal power, and biofuels as renewable sources. First of all, solar energy is the energy produced when the sun heats the solar panel. Thus, when the sun heat the panels, it produces electricity. Solar power produces energy during the day and can storage energy for the night. Solar power does not pollute so much the environment. However, it has high maintenance cost, and it takes a large land space. Secondly, 15% of World electricity comes from wind. In order to have wind energy, it is important to have turbines to get the wind in order to produce electricity. Tall turbines produce more energy. The drawbacks of wind power are that it requires steady wind and its installations may interfere with TVs, cellphones, and other electrical devices. However, it is quickly built and there is no pollution nor noise produced. Third of all, the water falls in the dam can also generate electricity. For instance, 19% of world electricity comes from water. Regardless of the fact that hydroelectric power has low maintenance costs and does not pollute the environment, it can cause earthquakes, and destroy wild rivers. Only 0.3% of world energy
A steam turbine's two main parts are the cylinder and the rotor. As the steam passes through the fixed blades or nozzles it expands and its velocity increases. The high-velocity jet of steam strikes the first set of moving blades. The kinetic energy of the steam changes into mechanical energy, causing the shaft to rotate. The steam then enters the next set of fixed blades and strikes the next row of moving blades. As the steam flows through the turbine, its pressure and temperature decreases, while its volume increases. The decrease in pressure and temperature occurs as the steam transmits energy to the shaft and performs work. After passing through the last turbine stage, the steam exhausts into the condenser or process steam system. The kinetic energy of the steam changes into mechanical erringly through the impact (impulse) or reaction of the steam against the blades.
...he better and enable their children to live in a cleaner environment. Building wind turbines in some areas might not be as beneficial. But it will benefit certain areas more than others because there are more winds flowing in a certain area. Places where there are more land will be perfect to build these wind turbines because it will generate huge amounts of electricity that can power many buildings. The area of location should be chosen with utmost care where there is an abundance of wind that in consistent. Since wind energy is a renewable technology that does not contribute to global warming, thus it will make a better and healthier
