What Is Wind And How It Works

Improved Essays
 What is wind and how it works :-
Wind is moving air and is caused by differences in air pressure within our atmosphere, Air under high pressure moves toward areas of low pressure , The greater the difference in pressure, the faster the air flows. Air may not seem like anything at all, in fact, we look right through it all the time, but during a windstorm, air really makes its presence known, Wind is able to lift roofs off buildings, blow down power lines and trees, and cause highway accidents as gusts push around cars and trucks.

 Describing Wind:-
Wind is described with direction and speed. The direction of the wind is expressed as the direction from which the wind is blowing. For example, easterly winds blow from east to west, while

Wind turbines have a role to play in both the developed and third world.
7. Wind turbines are available in a range of sizes which means a vast range of people and businesses can use them. Single households to small towns and villages can make good use of range of wind turbines available today.

 Disadvantages of wind power:-
1. The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.
2. Wind turbines are noisy. Each one can generate the same level of noise
3. Many people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They disfigure the countryside and are generally ugly.
4. When wind turbines are being manufactured some pollution is produced. Therefore wind power does produce some pollution.
5. Large wind farms are needed to provide entire communities with enough electricity. For example, the largest single turbine available today can only provide enough electricity for 475 homes, when running at full capacity. How many would be needed for a town of 100 000 people?

A joint venture with "DONG Energy" and "E. Online ", built farm London matrix to generate energy from offshore wind and ability to produce 1000 MW in the estuary of the River Thames, which will be the completion of the major electricity generation from offshore wind farms. And also they build a farm to generate power from the wind in the Seychelles which will meet 25% of its energy needs. In the near future they will build Farm Sir Bani Yas wind power, and estimated production capacity of about 30 MW, they just are waiting for the approval of the Executive Council, and also they are considering and planning to establish a farm to generate 100 megawatts of wind power near the Saudi

    According to results of the calculation of wind velocity and wind pressure, that shows the typical distributions. Thus explains why, while wind velocity increases less than linearly with height, pressure instead increases as a nearly linear function of height. Wind pressure is thus positive on the windward side, while it is negative on the leeward side, because of the suction effect produced by the airflow separation. The map of strong winds in Europe gives wind velocities at the standard height of 10 m above terrain, given that at ground level the velocity falls near to…

    This report will explain and present the advantages and disadvantages of the wind farm in Nant y Moch which is in Mid Wales. Scottish and Southern Energy Renewable Company SSE has been planning to establish a wind farm in Nant y Moch in 2005, Nevertheless this project is still controversial and not completely accepted by some organizations and local people due to the negative effects that may be caused by wind turbines. The biggest and magnificent benefit from wind turbines is to generate adequate electricity to local people who are living near wind farm and to support British economy dramatically.…

    Critique of “Wind Power Puffery” In his article, “Wind Power Puffery”, H. Sterling Burnett argues that the advantages of wind power are grossly exaggerated and often cause more harm than good. Burnett, an expert in America on environmental issues, has obtained a Ph.D. in philosophy and a B.A. in cultural anthropology. He mainly writes opinion based articles about current environmental and energy topics and wrote this article to express his opinion on wind generated energy. Supporters of using wind energy in place of burning fossil fuels claim that relying on wind power will decrease air pollution and greenhouse gas emissions, which Burnett strongly disagrees with.…

    On windy days, energy can be used in an increased abundance. A notable example of this case was in Spain; in 2010, Spain experienced a particularly windy year, so wind power accounted for 16.6 percent of the national net power consumption (Leung and Yang, 2012). India has also incorporated renewable wind energy resources into their economy; this action has landed them in fifth place amongst the other wind using countries. Ultimately, the countries illustrated above show that wind power is well distributed across the world; both developing and developed countries are involved in the switch to a more ‘green’…

    Turbines can be housed on the shoreline as well. The production of wave energy comes with consequences. Getting your energy source from waves is only suitable for those who live close to the coast. We would not be able to get this energy to places in the city. The production of wind energy occurs when the kinetic energy of the wind turns the propellers of a wind turbine.…

    Wind turbines operate on a simple principle; the force of the winds called “lift” pushes the blades of a wind turbine up, allowing it to turn the blades around a rotor. The rotor is connected to the main shaft which spins the gearbox whose gears convert the relatively slow rotation of the spinning blades into higher speed motion, turning the drive shaft quickly enough to power the electricity generator to create electricity. The rate of electricity currently being produced through wind energy in the United States is six million kilowatts an hour of power a year which is enough to power 1,500 households with electricity and that is just for an onshore wind turbine give source here. An offshore wind turbine produces an average amount of 3.6 Megawatts of power a year, this amount of power is enough to power 3,312 households with electricity.…

    Wind turbines can cause noise pollution that can lead to health problems such as hypertension, impaired cognitive development, minor psychiatric disorders and sleep disturbance (7). Finally, another disadvantage that wind energy has is its reliability. Wind does not blow consistently and the location of turbines can determine how much energy is stored. If the weather conditions prevent winds from occurring, then the electricity supply can be limited and costly due to supply and demand. Wind direction can influence how the wind turbines rotate and affect how much energy is…

    Wind Turbine EEI Discussion– Kate Richards To determine whether the number of blades on the wind turbine changes the amount of electricity or voltage produced, an experiment was carried out using a wind turbine, fan, retort stand, timer and voltage reader (appendix 8). A test for how much voltage was produced from a wind turbine with 4 blades, 8 blades, and 12 blades was carried out 5 times (appendix 2) (appendix 3) (appendix 4). This was repeated 5 times for each number of blades to ensure there were no inconsistencies in the timing or in the voltage readings. By averaging the results from each set of blades, it was discovered less blades create more voltage than more blades.…

    I would expect to find wind power near the coastlines, mountains and valleys. I would propose to put windmills for energy in Texas, Oklahoma, Iowa, Missouri, and Arkansas are just to name the few regions that are suitable for placing windmills in the United States. When considering creating windmills in the United States, it will cut down on lots of pollutants in the air like carbon dioxide. Pollutant in our air is causing people to have so many problems including astma and other respiratory problems that effect…
