The energy in the wind turns blades around a rotor, and the rotor is connected to the main shaft, which makes a generator turn to create electricity. The shape of the blade causes the air pressure to be uneven, higher on one side and lower on the other side. And that’s what makes it spin. On the top, there’s a weather vane that’s connected to a computer to keep the turbine turned into the wind so it captures the most energy. The blades are attached to a rotor which only turns about 18 revolutions a minute and that’s not fast enough to generate electricity by itself. So, the rotor spins a series of gears that increases the rotation up to 1800 revolutions per minute. At that speed the generator can begin to produce electricity. The windmills are tall, because the higher you go, the winder it is. The blades can sweep circle in the sky longer than a football field. A windmill can power up to 9,000 homes Oceans and the Great Lakes provide consistent source of wind that we can capture and turn into electricity. The wind turbine works opposite of a fan. Wind turbines use wind to make electricity instead of using electricity to make wind. The wind turbines convert the kinetic energy in the wind into mechanical power. There are two types of windmills horizontal-axis and the vertical-axis. Horizontal-axis windmills have two or three blades. The vertical-axis windmills main rotor shaft is set traversed and the main components are located at the base of the turbine. This arrangement allows the generator to be easy facilitating service and repair. The

Wind energy Essay

Wind Energy In the morning millions of Americans wakeup, make a fresh pot of coffee, and watch the morning news. A majority of Americans have no idea where the electricity comes from that supplies their everyday household appliances. It seems that electricity magically flows into homes form some unknown source. The face is that the production of electricity uses fossil fuels that are in short supply to operate the necessary equipment to make electricity. When this supply of fossil fuels runs out…

Essay on Wind Energy

Wind Energy: A Cheaper Cleaner Energy Wind energy was founded in the late 1800’s and has made significant advances in the 20th century. Now in the 21st century the increasing cost of fossil fuels has revived interest in alternative energy. Although fossil fuels are the most prevalent source of electrical energy, wind power is a cleaner and cheaper source of electrical energy. The first power producing windmill was built in 1888, and “within a decade, wind powered electricity had spread throughout…

Wind Is The Cure

Wind is the Cure By Vamsi Karra 6th period 11-23-14 Everyone has heard the tale of Benjamin Franklin’s innovative experiment: he flew a kite in a thunderstorm in order to demonstrate the presence of electricity. Though we don't know how genuine this legend is, Franklin helped lay the foundation for batteries, the electric motor, the lightbulb, and the true nature of electricity. While he used a kite to harness electricity from lightning, we normally think of kites as merely entertainment on…

Wind Power Research Paper

The Economics Of Wind Power In America Wind power currently serves about 0.1 percent of the entire electrical demand of the world today. There are several sources of energy that society uses today and the most prevalent source used is coal power. The need for a stronger, renewable, energy source is necessary as the consequences of the use of coal and other nonrenewable sources become more obvious. However, the costs of changing our energy resource is substantial and the reliability of these energies…

Wind Turbine Essay

Wind Energy A wind farm is a piece of land where many windmills or turbines are placed so when the wind blows, energy will be made. When the wind blows the turbines will spin making kinetic energy that is then put through a generator that turns the kinetic energy into electricity. Same thing happens with the windmills. The blades will turn then will be put into a kinetic generator. It is a natural power plant. Renewable energy is energy from a source that is not depleted when used. Such as…

Wind: Wind Turbines Essay

Wind Turbines It is a source of clean and renewable energy which will not generate any greenhouse gases, nor emit pollution or even produce any dangerous waste material. Each unit of electricity produced by a wind turbine replaces a similar unit of energy from a conventional power station. Wind turbines have highly successful where they have been commissioned in the UK, preventing the emission of almost 1 3/4 million tonnes of carbon dioxide per year. Wind is an abundant and reliable source of…

Hawaii Island Research Paper

there is wind, sunlight, mountains, and volcanos. Hawaii Island gets most of its wind at night at the top of the mountains. The strongest wind is at 5,000-7,000 ft above sea level. Hawaii Island has 3 very tall mountains. The mountains are Hualālai, Mauna Loa, and Mauna Kea. Hualālai’s peak is 8,271 feet above sea level. Since there is a trade wind between 5,000 and 7,000 feet with winds from 100-160 km/h Hualālai has 2,000 feet worth of mountain space that can be used for windmills. The same…

Alternative Energy Research Paper

Prof. C Comp. 1-Research Paper 7 Nov. 2008 Within the next few years, one can expect to see a vast change in the way that mankind harnesses energy. Alternative fuels will play a colossal role in what has become one of our generation’s largest challenges, limited supplies of fossil fuels. Scientists have been working for years to develop alternative methods to power the globe given that materials such as coal and oil are not renewable resources. Once they are used up, they are gone forever…
