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.
As the wind energy industry continues to grow, it will provide many job opportunities for workers and job seekers. These careers will extend beyond just the wind farm. To build and operate a wind turbine, it will take the efforts of many workers. The workers will be in factories and offices. There are construction employees, electricians, engineers, operators, gearbox makers and bla...

...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
Wong 4 choice that does not have a huge impact on our physical environment. Having a wind generator to use wind electricity can be cool depending on a person’s preference and is a strong statement of someone’s values and thinking.
2. Personally i am for wind farms and in my opinion. I think that wind energy has a great potential not only is wind energy very reliable and sustainable. it is also not as expensive as some at the other types of renewable green energy sources.
It is well known that nowadays wind power is one of the fast developing energy sources of the world. Thats why one of the GE’s Energy business maintain a strong focus on building the wind power facility and delivering the technology in its fields and benefiting the advantages of wind power. GE has over 12,000 wind turbine operating in all around world with the countries like USA, Canada, China and Spain.
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.
First of all, President Obama’s comments tell about how wind power is a clean and renewable way of providing energy. Also, wind energy has provided new jobs to people. Seventy-five thousand jobs across the United States depend on wind power. Wind energy and solar power combined are enough power to make sure that 13 million homes in America have reliable power.
Wind energy can play a critical role in saving our planet from the negative effects of energy powered by fossil fuels. Wind turbines work effectively at reducing carbon dioxide emissions. For instance, a single utility scale wind turbine can prevent the emission of 5,000 tons of CO2 into the atmosphere a year by displacing the power generated by fossil fuels. Also, a single 750-kilowatt turbine can produce roughly 2 million kilowatt hours of electricity annually. Turbines of this nature are the ones now being used in power plants around the world (Wind Energy Weekly). One good example is California. Their wind power plants displace 4.5 billion pounds of CO2 each year with the 3 billion kilowatt hours of energy they produce. To put it into an environmental perspective, that is as much CO2 as could be absorbed by a forest covering 1100 square miles (Wind Energy Weekly). Although wind energy has little to no impact on the environment when it comes to air pollution or greenhouse gases, there are other environmental concerns surrounding this form of energy production. Some of the concerns about wind energy include visual impacts, birds and other living resources, lightning and noise (Wind Energy Development).
Even without subsidies, there are many advantages to using wind power. Wind energy does not put pollution into the air, unlike power plants that rely on fossil fuels, such as natural gas or coal. http://energy.gov/eere/wind/advantages-and-challenges-wind-energy
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.
The technological advancement of wind mills to wind turbines has been largely contributed from science. This new technology has cause an uproar between two fractions. One fraction side goes against wind turbines as it has resulted in an increased of birds and bath mortality and has negative impacts to the human health (The Wind Resistance of Ontario, Unknown). The other fraction supports the use of wind turbines as it is a clean and renewable source of energy and it can reduce carbon emissions (Windfact, 2013). The use of scientific research da...
Just as long as 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.
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
For example, in 2011, the wind energy industry directly employed 75,000 full-time-equivalent employees in a variety of capacities, including manufacturing, project development, construction and turbine installation, operations and maintenance, transportation and logistics, and financial, legal, and consulting services. Other renewable energy technologies, such as the solar industry, employ even more workers. According to the National Solar Job Census taken in 2011, over 100,000 people were employed both part-time and full-time within the industry. That data alone is a promising figure considering renewable energy is still in it’s infancy.
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 ...
Wind power is one of the most sustainable ways of generating electricity as no toxic emissions are produced; it does not add to global warming and is one of the most available sources of renewable energy and theoretically it is an infinite source of energy. On sufficiently windy areas, wind turbines are one of the most economical methods of generating electricity, which makes it appealing to many individuals, governments and organizations. Due to this it is the fastest growing source of electricity in the world (Union of Concerned Scientists, 2014) with a 10% increase in yearly additions installed in 2012 compared with 2011 (Global Wind Energy Council, 2012). However the proportion of energy that can be harnessed through wind power is restricted by the cost of the infrastructure needed, construction, the amount of wind that occurs and that there are only a narrow number of sites within the UK that are windy enough for the wind turbines to be worth installing.
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 or noise produced.
