Wind+Power+Intro

__Wind Power __

Wind power can be an excellent complement to a solar power system. Wind power is produced by using wind generators to harness the kinetic energy of wind. It is gaining worldwide popularity as a large scale energy source, although it still only provides less than one percent of global energy consumption.

Wind Energy currently meets only a mere 1.5% of global electricity generation. Many asian countries are also trying to embrace clean and green energy. South Korea is going for an ambitious off-shore wind farm amounting to $8.3 billion. This project will be executed at the western coast of the Korean peninsula taking a time period of ten years.

Brief History:

Wind energy has been used for thousands of years. The Egyptians used it sail up and down the Nile. Persians and Chinese used windmills to grind grains. Windmills, of course, seem to be a national icon of Holland. American colonist even used windmills in the early years and wind energy was a major power source in rural America in the 1920’s. Simply put, there are a lot of positive reasons to use wind energy as a power source for our ever growing electrical needs.Some reasons are:
 * Wind is caused by temperature variations resulting from the sun heating up the ground. As long as the sun is cooking, estimated to be another 4.5 billion years, there will always be wind.
 * Wind is free unless you’re dealing with a politician.
 * Wind energy has no side effects resulting in pollution.

Many People say Solar wind power is the power of the future...

As the world discovers new ways to meet its growing energy needs. The sun creates what we call solar power and obviously wind creates wind power. Though these two sources of energy have attracted the scientists for a very long time, they are not able to decide, which of the two is a better source to generate power. Now scientists are looking at a third option as well. Scientists at Washington State University have now combined solar power and wind power to produce enormous energy called the solar wind power, which will satisfy all energy requirements of human kind.

Wind Turbines
Wind turbines, like aircraft propeller blades, turn in the moving air and power an electric generator that supplies an electric current. Simply stated, a wind turbine is the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Wind Turbine Types
Modern wind turbines fall into two basic groups; the horizontal-axis variety, like the traditional farm windmills used for pumping water, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines.

Here are some of the ways in which wind energy proves beneficial to us.
 * Pros of Wind Energy**
 * The biggest benefit one can reap out of wind energy is that it generates electricity, but does not release any harmful pollutants or gases as by products. This therefore makes it a safer and cleaner source of energy.
 * Wind energy is also one of the cheapest forms of energy available today and therefore it can be used by everyone, including poor farmers from rural areas.
 * Farmers can not only use the electricity for themselves, but can also earn income out of it, by providing electricity to several homes.
 * Wind energy does not involve the use of any fossil fuels or non-renewable sources of energy like natural gas, coal or oil. This proves that it is an efficient renewable energy.
 * Wind is a never ending resource, therefore power cuts and power failures are almost non-existent in areas that rely upon wind power to generate electricity.
 * With the use of larger electric grids, higher amount of electricity can be generated, which thus makes electricity accessible to a larger number of households in the vicinity.
