Wind Power

By: Austin Flanagan

Pros Wind power is a renewable source of electricity

*The generation of electricity by the burning of coal is non-renewable and emits carbon dioxide to the atmosphere.

The Pros for Wind Power

ConsThe rotating blades can be lethal to birds. Wind farm design also need to consider the migration pattern of birds and avoid bird migration flyways.Wind turbines are highly expensive and are harmful too wild life.

The negatives of Wind Power

One source of Wind power are Windmills which are helpful to the world because they can pump water from under ground. These are called Wind Pumps, which the water taken is used for drinking, cooking and raising live stock.

A source of Wind Power

The way Wind Power works. The conversion of wind into electricity begins when the moving air contacts the blades of the wind machine. (turbine). A turbine is a device that converts kinetic energy into the mechanical energy. The movement of the blades shows the movement of the wind. This causes a difference in air pressure, and the movement of air from both high and low surface areas of the blade. The blades are attached to a shaft. As the shaft turns, an electrical generator positioned at the top of the wind machine produces electricity. A cable that runs down the center of the machine conveys the electricity to the ground, where it feeds into a transmission line.

Wind at Work

Wind can result from the uneven heating of the land and water. Land tends to absorb the heat of the sun more quickly than water does. Because warm air rises, cooler air will take its place. This action creates wind.

United Kingdom confirmed construction of about 600 turbines in 2007. When these turbines become operational, combined with existing facilities, the aim is to harness enough wind energy to power the United Kingdom by the year 2020.
