Hi guys. It’s Carol and today’s topic will be renewable energy, but more specifically wind energy and the sustainability of wind farms.
So what is wind energy and how do we get it?
Wind energy is a source of solar energy powered by the uneven heating of the atmosphere by the sun, irregularities of the earth’s surface and earth’s rotation⁸. Think back and remember geography from 9.
Wind energy is basically a reverse of fans⁸. Instead of using energy to produce wind, they use wind to produce energy. Awesome Right?
So many of you are probably thinking that wind farms are unsustainable and that it would be a bad idea to build one in the GTA. And I think you are all wrong.
Let me start with this. Wind power has 20, TWENTY times more potential than

For example, endangered species and threatened habitats, protected areas, historical or archeological sites, aviation and more³. But what we hear about the most is bird and bat migration. More specifically birds getting killed by the turbines, however did you know that of the 9 major causes of bird deaths, wind turbines don’t even make the list! 14 million by vehicles, 25 by collisions with houses or buildings and 200 million by domestic and feral cats²! Who would have known! Definitely when building turbines, the factors listed before have to be taken into consideration, but the public should know that wind turbines do not have a major impact on bird …show more content…
Wind turbines cannot be built any closer than 300 meters from residential areas. And from that range, the wind turbines make as much noise as your refrigerator⁵. And is comparable to background noise. People do not complain that they cannot sleep due to the refrigerator noises⁵. Besides we live in the GTA. Constantly we are surrounded by the noise of traffic or what have you, so the turbine noise and the background noise are blended together¹. Since there is no difference in noise levels between having a wind turbine or not, it is better to have a wind turbine and try to save our environment, save the Earth. It’s the only one we have so we should take care of it. Thank you for listening to this rant.

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.
Its most known process of generating electricity would be movement of air through wind turbines. Wind power has two parts, mechanical and electrical systems. Mechanical systems are low speed and are used for mechanical tasks such as pumping water or grinding grain. Electrical systems are high speed and are used to generate electricity to power homes or schools. Many people feel that wind farms full of turbines, are aesthetically unpleasing, but wind power is a clean energy source and does not generate greenhouse gas emissions. It is a very abundant resource throughout the United States. Wind power is simple, relatively cheap, and low maintenance (Sambu). Wind power is again, free and very abundant so no matter how much we use now, we will still obtain enough in the
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.

Wind turbines can be very useful in bringing energy into your home. They are especially useful when solar panels aren't working. They take the wind speed from oceans, lakes, dugouts, or rivers and turn it into energy. To use the wind turbines most efficiently you should set up a wind power system.
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.

Reading up information and searching for clues (which were not extremely easy), turns out to have broadened my knowledge on Nature and Biomimicry itself and that there are so many people already using wind turbines to harvest the winds energy and know how the world can be saved. Therefore I have come to the conclusion and have seen that my hypothesis has been proven right.
One of the areas that suffers because of this backward thinking is the development of renewable energy sources -- and the topic of this section: Wind Energy Conversion.
When picking an energy resource for the topic of this paper, I bounced around a lot of ideas. Then it occurred to me that I should write about what I will be living with in about a month. My mom just finished designing and building our earthbag, solar, off-grid house, a four-year endeavor. I will soon live in a place powered by one of the most common alternative energy resources, solar energy, so I should learn more about it.
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 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.
