Wind Power

 

Part 1  

 

Wind is the movement of air from an area of high pressure to an area of low pressure. Wind exists because the sun unevenly heats the surface of the Earth. As long as it shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives.  Wind turbine usage has increased more than 25 percent each year. Wind turbines are made up as three different blades  that spin in a circular motion to create electricity. Wind power is a clean source of energy and creates no water or air pollution. The cost of building a turbine is minimal once the turbine is erected. A possible negative is that many people find them noisy and unattractive. The rotating blades sometimes kills birds. To make these energy systems the governments offers tax incentives to encourage wind-energy development.

Part 2

During the 20th century small wind stations were built among farms or residences and connected to electricity grids. Today the generators powered by wind come in every size from small stations that are battery charged to gigawatt offshore wind farms that provide to national levels. Constructions of offshore are located near bodies of water to generate electricity. Hundreds of individual turbines are dispersed over a large area of land however agriculture may use in between the turbines.  These turbines were and still are transported by convoy, however more frequently  they are assembled on site to reduce transportation difficulties and moving these extremely large pieces amongst traffic and pedestrians.

Part 3

There are numerous incentives for using wind power. The federal government offers Corporate Exemptions and Tax Credit.  The federal government also provides grant programs, loan programs, personal tax credit and personal exemptions for home owners.

Wind power does have some obstacles to overcome. It is dependent on large subsidies, wind energy is fairly limited, and a high portion of the funding is upfront with limited return.
