As air moves, giving rise to wind, it develops kinetic energy like any other mass that gets into motion. With the help of appropriate technology, this kinetic energy of wind can be harnessed and converted to different forms of energy that include mechanical and electrical power. This is what is referred to as wind power. Wind power is also a variation of solar power since it is primarily caused due to the solar heat warming the earth’s surface. As the rays of the sun hit the earth, all the regions are heated up (unequally) that include different parts of the terrain as well as the oceans. When one particular region gets more heated than its neighboring location, the air above it becomes lighter and goes up, creating a temporary low pressure area there. As a result, the surrounding cool air rushes in to fill up the void. Known as Thermal, this is how storm conditions are brewed and the wind develops its power.
This power of the wind was known to us since the earliest days when we utilized it to propel sailing boats first and then large seagoing sailing vessels that roamed freely all over the oceans. In fact, veteran sailors were so enamored of the wind’s driving power that some seasonal winds were given colloquial names like the Trade Wind, Continental Wind, Roaring Forties, etc. The great explorer, Christopher Columbus was so sure of wind power that he sailed confidentially for more than a month at a stretch before his men could locate land.

From the Wind” in which the writer profiled several
success stories in praise of residential wind energy for
generation of electricity. It contained, among others,
accounts of how Rena Wilson and her husband had taken

Today, wind energy is labeled as a safe and clean energy and it is utilized by many Americans to generate electricity for home use while large wind parks have started providing power to the national grid. It certainly seems like wind power is the future. Personal wind power is great news because on the one hand it is clean and good for the environment, and on the other, it saves you on your power bills. But cheap wind power is even better. It is the right move to install such a system because of the tremendous advantages. But before you can gain from cheap wind power, you need to know a few things such as where to buy cheap parts from, safety precautions, choosing the best location and wiring the system.
