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.”
These include the history of windmills and their role concerning the survival in the immense plains that range from east of the Rocky Mountains to the Mississippi River. The rise of the economic condition of those living around the wind farms along with the surge of investments from energy companies. Finally, the promising data relating to the amount of energy produced, and the consequences they will have on the environment. In the later and longer part of the article, the possible negative results or wind farms are brought up. Primarily, the points against wind farms have to do with the conservation of wildlife. This is separated into two sections, the first addresses the dangers wind turbines present to birds, the other on the dangers presented to bats.
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
The rhetorical occasion of this excerpt is to inform others about the dangers of chemicals on earth’s vegetation and animal life.
"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.
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).
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
When reading the book “In Cold Blood” by Capote, Truman I came across many assertions one in particular discussing how the law is hypocritical. In the assertion it talks about killing and how it is a crime, but enforces it as punishment and justice. Thus showing how the law is contradicting itself. In my paper I hope to further explain and show how killing is in fact a crime, but can be used for justice.
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

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.
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.
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
...ave any long-term effects. This is of course different for the Atlantic Ocean. Sound Science is going to be used to avoid, minimize, and mitigate direct and indirect impacts of this project. The major habitats and environmental resources that can be impacted are seafloor habitats, coastal habitats, fishery resources, marine mammals, marine and coastal birds, and bats. The start of the building of these offshore wind turbines will disturb some species’ daily or seasonal movement patterns. Some habitats will avoid areas that have a disturbance and will never return to that area. When building these wind turbines, they should be placed as far offshore as possible, avoid sensitive areas, try not to build near areas that are already indicated by the state or federal government to have some problems, and utilize best management practices to try to minimize projects risk.
According to World WildLife Fund, many ecosystems around the world are being destroyed, eliminating many plant and animal species that inhabit them (“Pollution”).
Wind is a form of solar energy. The term wind energy describes the process by which the wind is used to generate electricity or mechanical power. Wind turbines convert mechanical energy from the wind into electrical power. Wind turbines usually have three main parts. There are blades that connect to a central hub, a box behind the blades that contains the generator, and a long stem that connects to the ground. The way how it works is that the wind turns the blades, which spins a shaft that connects to a generator making electricity. After the electricity is produced it is sent through transmission lines to a substation that is sent to business and homes. For the sake of our planet, we must promote a renewable energy economy. Wind power can be a foundation of that sustainable energy future because it provides jobs in states that are building wind turbines, is a renewable energy source, and does not damage our environment. The environment will not be damaged by the pollution, the natural resources will not be used up, and there won’t be generating of hazardous wastes. Welcoming wind energy today will lay the foundation for a healthy tomorrow that will affect everyone in the United States. There are obstacles and challenges that will make it more difficult, but the environmental impact is well worth it to invest more money into wind energy.
