The Power of Wind

Wind energy is a free and limitless power source. No matter where you go, there will always be wind. In the past, wind was captured and controlled through the use of sails for the powering of ships. Now that larger amounts of energy have been found, through the burning of fossil fuels, the art of sailing has faded to a recreational sport. Wind has also been used in the past to power mills, which have been used to pump water and grind grains. Though now these techniques of harnessing wind’s power are now not widely used, even though it is an effective power source. Wind is created by the uneven heating of the earth’s surface, and; therefore, is an unlimited source. The problem with fossil fuels is that they are pollutant and will eventually run out, whereas wind is clean and abundant. The technology and efficiency of windmills has improved significantly over the numerous years that they have been around.

The windmill is a large vertical structure that can stand up to 500’ tall with blades as large as 250’. As the wind passes the rotor blades, the blades are forced to spin, therefore rotating the main shaft. Now, do to modern computers, windmills have been able to utilize a gearbox, improving the effectiveness of wind energy. These gears will control how fast the high-speed shaft will spin, the faster it spins in the generator, the more power that is produced. Then, the power is transported down the tower and directly into the city grid system.

Wind in the Future
Wind energy is definitely going to be a valuable resource in the future. The New York State Energy Research and Development Authority has a Renewal Portfolio Standard which requires that 25% of our electricity be produced from renewable sources by 2013. This shows that the US is already converting to renewable resources such as wind and solar.

Wind Energy : Wind Power Essay

- INTRODUCTION Wind energy is gaining popularity throughout the world. Due to growing importance of wind energy, the rapid development of wind energy technology has a large involvement of people and institutions. Wind power is increasingly being viewed as the mainstream of electric power supply due to: zero emission of harmful gases ,significantly economically exploitable resource potential , no cost uncertainties from fuel supply price fluctuations, modular and rapid installation opportunities for industrial rural and economic development, which majorly constitute its benefits....   [tags: Wind power, Wind turbine, Wind farm]

Wind-Power: An Alternative to Hydroelectricity Essay

- The supply of fossil fuels is drastically depleting, and the consumption of energy causes multiple problems which include: global warming, pollution and geopolitical conflicts according to Dan Hogan, editor of sciencedaily.com. One respective alternative would be wind-power. Wind-power can be used as both electrical power and mechanical power. Electrical power refers to fuel that has been converted to electricity. Mechanical power is fuel used as a primary, opposed to secondary, source – in regards to wind, anything it pushes around to activate would be using a Mechanical power....   [tags: energy, wind, power]

Essay about The Effect Of Wind Power On Wind Energy

- The focus on wind energy will become the end of the world’s economy, electricity, and survivability if we continue to only focus on this source of power. Governments should decrease production of wind energy alone, and instead formulate a plan that consists of all “green” energy sources, which in turn will provide maximum power outage. There are many problems with wind turbines, two of which are major drawbacks. Wind turbines become inefficient when the wind is not blowing (National Geographic)....   [tags: Wind power, Energy development, Wind turbine]

The Cost Of Wind Power And Hydroelectric Essay

- ... This large discrepancy again comes from the difference in dam sizes meaning that although some dams produce more energy than a wind farm the cost of building and management causes the power generated to not be as impactful as the cost to generation ratio of wind farming (Bureau of Reclamation). Proving further that the use of hydroelectric power is an irresponsible idea as far as power output to power price is concerned. As when the price of power production goes up so does the price of actual electrical power....   [tags: Wind power, Wind turbine, Renewable energy]

The Sky is the Limit For Wind Power Essay

- Owen Paterson said “The relationship between renewable energy sources and the communities we expect to host them must be appropriate and sustainable and, above all, acceptable to local people.” For that reason, environmentalists have long assumed that wind power is a much more efficient and sustainable way to generate electricity. However, non-supporters of wind power state otherwise because there are a few negative outcomes to using wind power. Ultimately, when it came to the nature of wind power the basic assumption was that it is beneficial to the environment and communities....   [tags: Renewable Energy Sources, Wind Power]

Essay on Renewable Energy : Wind Power

- One of the fastest growing and most promising renewable energy source within the United States is wind power. The most prevalent form of wind power generation comes from large fields containing numerous elevated turbines (Fthenakis). These fields are known as wind farms and are connected directly to electric power systems. Using turbines to harness the wind offers the United States, as well as the world, an opportunity to generate huge amounts of energy in a clean process that has little to no negative effects on the environment....   [tags: Wind power, Renewable energy, Fossil fuel]

Wind Power And Solar Energy Essays

- 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....   [tags: Renewable energy, Fossil fuel, Wind power]

Essay about Wind Power And Solar Energy

- Wind is a form of solar energy that can be used to do work. The wind turbine is the actual device that is used to make electricity. Wind turbine looks like a fan, but don’t be fooled because it doesn’t work like a fan. Wind turbine uses wind to make electricity while a fan has a cord that needs to be plugged into an outlet to create electricity, so don’t mistake them for the same thing. Turbines can be used to make the majority of our electricity. The wind turns the three blades, next spins the shaft that connects to a generator to create what we see as electricity that can be used immediately or store for later use....   [tags: Renewable energy, Wind power, Fossil fuel]

Wind Power Essay

- Wind Power Harnessing the natural power of the wind is by no means a new concept. Asides from sailing, wind power has been utilised for many thousands of years, principally for agricultural purposes. Basic windmills are thought to have been used in Persia (now Iran) as early as the 7th century AD. Their ability to make use of otherwise untapped energy sources without the needs and costs of other alternatives, ensured that they remained the machines of preference in several industries throughout both agricultural and industrial revolutions....   [tags: Wind Power Energy Sources Essays]
