Earth, as of today, is a world run by fuels and electricity. Every man, woman, and child is directly affect by them, whether it is by its consumption, uses, or price. One of the more recent sources for these fuels and electricity isn’t actually very recent at all. Wind Energy, or Wind Power when it is being converted into a useful form of energy, has actually been around for thousands of years. It has been used to push ships, as natural ventilation, and to pump seawater.{Insert thesis Here}
James Blyth was a Scottish scientist who created the first electricity generating windmill, which powered his vacation home in Marykirk, Scotland. The United Kingdom soon ruled his invention uneconomical, or a waste of time and resources, because they believed it to be an unreliable source of electricity and more intended for scattered populations. Sometime later, Charles F. Brush, a brilliant inventor who has dozens of other inventions, built a fully automated wind mill designed specifically for the production of electricity in the city of Cleveland, Ohio. It was over 60 feet tall, weighing over 40 tons, and able to power a 12 kilowatt generator. Windmills during the 1900s really took off, in some countries the number of windmills reaching over 2500. These windmills provided power for things such as pumps, mills, and other heavy duty operation.
Windmills have been around for centuries, as early as 200 B.C., in such places as Persia and Iran. Hero of Alexandria was one of the first inventors to harness the power of the wind to power a machine, an organ, but this invention wasn’t as practical as other windmills found during that time. In the more eastern province of Iran, Panemone windmills were becoming more common. These were used to grind gr...

...an also be complaints against the noise created by the turbines. These turbines also have a degrading nickname, killer blades. They earned this nickname from the birds they have killed. On average, Wind turbines have caused 20,000 to 37,000 deaths of birds every single year. But this amount is actually quite minute. Over 90 million birds die every year from crashing into buildings, 130 million from collisions with telephones wires, with many more being killed from pesticides and domestic animals.

As the world's population grows, and the already extensive use of technology in our daily lives expands and grows deeper ingrained into our lifestyles, many people overlook the shortcomings of this type of life style. What is powering iPods, computers, and televisions? Currently, the world releases over 26 billion tons of CO2 per year. Americans release about 20 tons of CO2 on a per capita basis annually; however poorer countries limit their annual per capita emissions to less than 1 ton. Many people fail to realize how much of a monetary burden cheap and clean energy would relieve for the poorest two billion people of this world. Some would argue it could in fact be the biggest fundamental change this world sees, when we have a viable solution. Almost everyone in rich countries overlooks the cost of electricity due to the small portion of our budget it accounts for [1]. Wind will need to be part of the clean energy equation. Using wind turbines alone could redu...
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.
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).

Wind energy is starting to account for a lot of renewable energy around the world so why would it cause issues amongst people that live in certain regions? Wind farms do not only irritate locals, they also cause stress on the animals that inhabit the areas these turbines are being built. In the article “Not on my beach, please” written by the Economist in 2010, they show that wind technology may cause issue in some eyes but made others feel better about their region. In the article they also state that the wind turbines can cause issue for migratory birds and other fauna inhabiting these regions.
Another “con” is that birds and bats could fly into the wind turbines. This could be a real problem, and the technology should be improved to minimize this
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
Have you ever met anyone who can build a functioning windmill from scratch with little education? William Kamkwamba, the author and autobiographer of The Boy Who Harnessed the Wind, tells us his incredible life story, complete with famine, hardships, and triumph in the city of Malawi, Africa. Throughout the book, we see William grow and change as he and his family battle poverty and other losses. With William’s help, we begin to notice elements of his culture contrasted to our own, and cultural diffusion between Malawi and the USA.
Solar is a viable alternative energy source with solar panels becoming more affordable and more efficiently designed.
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
The purpose of this lab is to see how many blades on a windmill will create the most voltage. Another purpose of this lab is to find out at what blade angle will the windmill create the most voltage. Wind energy has been used for thousands of years because it is a renewable source; therefore, the wind power will never run out. WInd energy had been put into use by 5000 BC ,and simple windmills in China were used for pumping water, and vertical-axis windmills were grinding grain in the Middle East. The new technology of wind energy was taken to the New World in the 19th century for pumping usage and to generate electricity for homes and
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.
