The Power Of Wind

by Jerry Winston

People have been using the power of wind since ancient times to drive forward their boats and ships.

The first wind wheel that was used to harnass the power of the wind, was designed by the Greek Heron of Alexandria in 1 AD. 

The first windmill as we know it today was probably used in the 9th century in what is now Iran.  It was used thereafter in the Middle East and Central Asia. 

Even the Chinese later started using the windmill.  By 1,000 AD the Chinese used windmills to pump seawater in their production of salt. 

The first electric wind turbine was a battery charger that the Scot James Blyth used in July of 1887 to provide his holiday home with light. 

Shortly after, the American Charles F. Brush developed the first automatic wind turbine that could generate electricity. 

In 1881 the British mathematician Lord Kelvin suggested that wind power be used when cole reserves are depleated.  Solar power was also suggested during those times as an alternative power source. 

Because of the growing shortage of non-renewable resources like oil and coal, we must consider alternative energy sources like solar power and windpower, that are renewable. 

In the 1970's people worldwide realized that non-renewable energy sources can indeed be depleted, and there came also a big emphasis on the negative impacts of these resources.  The most publicized of these is global warming. 

For a clean energy source, wind is a perfect solution:  There is no air- or water pollution, and nothing is burned in order to get energy out of it. 

Wind energy is also not as expensive as some of the other options for cleaner electricity, even if it is very expensive to set up initially. 

Since May 2009, 80 countries agreed to use wind power on a commercial basis. 

A simple wind powered generator consists of a series of magnets and a conductor. 

Inside the generator the axle is connected to the magnets that turn around the conductor.  When the rotor rotates the axle, the axle rotates the magnets.  This generates an electrical current in the wire. 

The electrical current then sends the electricity via the power cables to a power station for distribution.
