“A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy”. (1) The inventor of the first electric wind turbine was Clevelander Charles Brush, who ran his entire Euclid Avenue mansion off of one for 20 years, which later made the cover of Scientific American in 1888. (2) Although the use of alternate energy didn't rise a great deal afterward, this event did open the eyes for many environmentalists. Wind power is only one of our several “energy source[s] whose ‘fuel’ is free and will never be exhausted” (3) with the pros and cons not completely weighed out as to whether it will be truly beneficial or not. The two main issues regarding wind turbines are the environmental effects that they have and the cost effectiveness of building them. One of the biggest negatives of wind turbines is that they have been reported as a source of death for many birds. “The largest causes of mortality among birds include loss of habitat due to human infringement, environmental despoliation, and collisions with man-made objects”. (4) This effect on the ecosystem appears to be important, but others disagree. We can know for certain that there are some effects that wind turbines are having on the environment, simply from the fact that it is a man-made structure placed within the environment. How much of an effect they are having on the environment, however, still seems to be in debate. The Danish Energy and Environment agency has done one of the more intensive studies on the effects of wind turbines and has spent the last eight years studying and observing two large offshore wind farms, Horns Rev and Nysted.

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.
Not only is wind energy better than fossil fuel energy, it is also better than other new energy sources. “Wind costs are much more competitive with other generating technologies because there is no fuel to purchase and minimal operating expenses” (Wind Energy Basics 3). And as for the environmental concerns of bird population, the American Wind Energy Association said, “the modern wind turbine is far less harmful to birds than are radio towers, tall buildings, airplanes and vehicles and numerous other manmade objects. Bird deaths due to wind development will never be more than a very small fraction to those caused by other commonly accepted human activities” (Parks 58).
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
Offshore wind power has become a need of the hour in renewable energy production due to the rising prices of oil and continually increasing demand for a separate energy sector. Offshore wind has the prospective to deliver at least four times the current U.S. demand of energy, as per mentioned by the Global Wind Energy Council. However, there are many challenges and advantages that are significant for us to comprehend.
Reduced area for the large fishes, too much noise in the water from turbines and constantly rotating blades could be disturbing for the marine life and seriously affect it. A project in Strangford implemented a security feature that automatically turns off the turbine whenever a marine animal was approaching towards it. Even the frequency and amplitude of the sound produces by the turbines could be harmful for marine animal so all possible effects should be considered and precautions are needed to keep as much marine life safe from turbine as possible.

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.
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.
The European Wind Energy Association have intensions of installing offshore wind farms with 40 GW rating by 2020 and 150 GW rating by 2030[2]. Professor Mark Z. Jacobson at Stanford conducted simulations in which massive arrays of offshore wind farms were used to try and reduce the wind speed of hurricanes. "We found that when wind turbines are present, they slow down the outer rotation winds of a hurricane," stated Mark Jacobson [3]. Using their sophisticated climate-weather model, the researchers simulated hurricanes Katrina, Isaac and Sandy to examine what would happen if large wind farms, with tens of thousands of turbines, had been in the storms' paths. They found that, as the hurricane approached, the wind farm would remo...
Urban area has been defined as a terrain with a population of 50,000 or a bunch of 2,500 to 50,000 people according to the US Census Bureau. Rural is later defined as anything external to that definition. Particular challenges are faced by rural areas when matter is of energy and water usage. For instance, utilities have to pay higher costs to modernize their energy groundwork and often find it stiffer to implement cleaner technologies because of the great distances between customers and crooked patchwork of reliable resources. Moreover, many system organizers and thought leaders for ground breaking energy know how live in suburban or urban areas and may discover it tougher to relate to the particular challenges of rural locations.
Alternative energy is a great foot path for the U.S. to take in finding a new and abundant source of usable energy. Alternative energy is energy that is manifested in methods that do not take away from natural resources or damage the environment, specifically by evading the usage of fossil fuels and nuclear power. Wind power is just one of the many great ways to use an abundant and natural resource to make useable energy. Wind turbines are the central representative in the wind energy harnessing department. Although the costs of producing wind energy harnessing equipment could prove to be steep, the output of the products could make up for the costs.
Is it practical? Is it safe for wildlife? These are some of the questions people ask when this topic comes to the conversation. According to Frederick Willis, installing wind turbines does not necessarily produce power or provide power at an economical cost; perhaps on a future we can give wind turbines a better use at a lower cost.
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.
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.
The Wind Turbine is a device that converts the kinetic energy of the wind into kinetic energy of turbines. The turbines turn to generate electricity but they work only when there is wind. The efficiency is 30-40%. The environmental impacts are needs many large turbines to generate electricity which can be noisy and unsightly. Turbines may endanger birds and bats.
