Wind Power Density:
Can It Be Measured?

Wind Power Density

As we clamor for a sustainable and viable source of energy in the face of an imminent energy crisis of global proportions, wind energy comes as a veritable godsend. It is believed by many, and not by environmentalists alone, that manís salvation lies in adopting alternative sources of power. The advantages of using alternative sources of power such as wind power are plenty. As a means of getting renewable, clean energy, wind power scores very high, perhaps second only to solar power. And in some aspects, it even tops solar power. Conventional energy production methods have always contributed to environmental pollution and have also led to the rapid destruction of the planetís natural resources. The emission of carbon dioxide, that such conventional methods of energy production are accompanied by, has always been a major problem. The gradual depletion of the naturally available resources, such as coal and petroleum products, is another major cause for concern. By employing wind power, one can easily get all the power one needs without endangering the environment or threatening the future of the planet.

Apart from being an excellent choice as a sustainable as well as a lean energy resource, wind power also comes with a distinct cost advantage. The cost of electricity is forever rising. The monthly bills of the average householder are on the rise too. On the other hand, by adopting wind power one can satisfy all of oneís energy requirements at a fraction of the usual cost. In fact, wind power is the least expensive source of renewable energy. After the initial setup costs, electricity produced by wind power can be enjoyed virtually free. Depending on the size and capacity of a wind power system, one can cut monthly electricity bills by as much as 90%! Today, commercially produced wind power electricity would cost as low as 5 cents for every Kilo Watt Hour (kWh), which is almost at par with new coal.

The performance of wind power generator systems depends much on what is known as the wind power density. For the uninitiated, wind power density basically signifies a measure of the potential of the wind to generate power. As a rule of thumb, one must have the wind blowing at a speed of 11 km/hr. to be able to generate any appreciable amount of electricity from it. Wind power density varies widely from region to region. In some areas, like those near the sea, the wind power density can be very high, while in some other zones, it could be discouraging due to low wind speeds. Wind power density has a very important bearing on the quality and the amount of electricity that you can generate. Simply out, higher the density, more is the energy that you can make.

Wind power systems, almost always, consist of a turbine system fitted at the top of a tower. The height of the tower is also dependent on the local wind power density. You see, if you experience fairly strong winds in your locality, you can make the height of the tower short. However, if you have the wind blowing mostly at moderate or low speeds, you would require a taller tower.

To enjoy the many benefits and advantages of wind power, all one has to do is set up a wind power system for himself. However, this might be a difficult proposition for those who are new to the technology or have no prior experience. Therefore, a good instructional guide is strongly recommended. By following step-by-step instructions, even the most inexperienced person can set up a fully functional wind power system and start enjoying its many benefits. Get all the assistance you need on various aspects as buying the right equipment, setting it all up, finding the best place at home to set it up, wiring the system, learning about the safety precautions and finally generating wind power electricity successfully.
