Imagine getting free electricity, or electrical company’s paying you instead of you paying them, today’s windmills just might make this possible. Windmills dating back as far as the 1400’s have been used to turn wind into useable energy for grinding and pumping. Today’s windmills turn turbines to make electricity. They are popping up all over the United States, but the United States is way behind other countries in the development of wind energy. Countries like Denmark, Germany and the United Kingdom are investing billions of dollars into wind energy, including off shore wind farms. Germany is holding the top spot in the production of wind-generated electricity. Denmark, being one of the smaller countries in Europe, produces twenty percent of their electricity from windmills (Eco-logical, 2004).
Wind energy has grown only twenty-six percent over the last five years in the United States (Eco-logical, 2004). This is sad in comparison to other countries, considering the technology and manufacturing capabilities of the United States. Is it because it is not windy enough for windmills in the United States? Not hardly, windmills are better today then they were ten years ago, needing only a wind speed of thirteen mile per hour to turn the turbines. Could it be the cost? Well according to an article in Eco-logical (2004), once the construction is done there is very little maintenance, so the operation of the wind turbine is virtually free. Meaning wind; the fuel for the turbine is free.
One reason for the slow growth of wind power in the United States is politicians. The problem is not just at the federal level, but state and local governments as well. Politicians not taking the time to research the magnitude of wind power and lobbyi...

Joel Salatin is a 57 year old farmer who has been farming full time since 1982 on his farm “Polyface” which is located in Swoope, VA, where he is somewhat of a local legend in farming. “The farm services more than 5,000 families, 10 retail outlets, and 50 restaurants through on-farm sales and metropolitan buying clubs with salad bar beef, pastured poultry, eggmobile eggs, pigaerator pork, forage-based rabbits, pastured turkey and forestry products using relationship marketing” (Salatin, Polyface.com). Mr. Salatin utilizes a unique method of farming, a fact which makes him so profoundly interesting. The style in which he farms his land is termed “mob grazing”. Mob grazing is the process in which different animals are rotated at different times throughout the farms’ fields. He is an advocate not just for the human well being but for the world’s ecological sustainability and the continuance of growth.

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.
In 1986, the National Renewable Energy Laboratories developed a wind resource assessment for the U.S. Department of Energy. The assessment consisted of surface wind data and upper-air data. The results of this project help today’s developers determine the best location for a wind farm, as shown in the map below.

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.
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.
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.
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

Wind turbines are a great source of energy all around the world. Wind Turbines produce wind energy that can be used to power our homes. Wind turbines convert Kinetic energy into mechanical power. Then this mechanical power gets generated into electricity. Wind turbines make energy by the wind turning the large blades, which spin a shaft that is connected to the large blades, which then operates the generator making electricity. One new idea is building wind turbines offshore in the mid-Atlantic. Offshore building of wind turbines means that these large turbines will be placed in the Atlantic Ocean. The building of these wind turbines will provide energy to states like Maryland, Delaware, New York, Virginia, and New Jersey. These states want to start this project as soon as possible so that the states can start saving money. Since these regions right now are burning fossil fuels uncontrollably with incredible impacts (not only to our air, but to our health) it is crucial to start right away. Offshore wind turbines will provide more jobs, cut pollution, stop warming of our planet, and save us energy costs. These wind turbines can make enough energy offshore to power about 500,000 thousand homes. However, many people disagree with this idea because they believe it is too expensive.

The wind is an incredibly valuable renewable energy source and is in the forefront of renewable energy developments. It is used to convert wind energy into energy that can be harnessed and used via a variety of methods, including; wind turbines, windmills, sails and windpumps. For a renewable energy source, however, it is wind turbines that are used to generate electricity (see figure 1). Wind power has been used for this since the end of the nineteenth century, after Professor James Blyth of the Royal College of Science and Technology first attempted it (Boyle, 2012). However, It wasn’t until the 1980s that using wind power technology was sufficient enough to experience a rapid growth of the technology.
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.
