The world at present is going through an energy crisis. While it is true that this phenomenon is more acute in the developing nations, the developed world is also not free from it.
The largest copper production in Chile is on the verge of being shelved due to acute power shortage. The country needs to increase its power production by 47 percent in the next eight years to keep abreast of the rise in demand.
Countries like Egypt and India also have gone through sever electricity crisis. This has been largely due to the huge gap between the demand and supply.
These incidences show that the power sector needs more investment for the production of electricity. Now coal, natural gas, hydropower and nuclear power are viewed as the main sources of energy. But the time has come to give thrust to alternative renewable sources of energy. In this connection, harnessing wind energy for the generation of electricity is of paramount importance.
The shortage of electricity has many different components like the escalation of demand, weather condition and distribution. But availability of the power is the primary concern.
Technologies to harness wind energy in a cost-effective manner have advanced to a great extent in the last decade. This had been made possible due to the tax credit by the Federal government. It also poses no hazard to the environment.
The wind projects can both be taken up on a small or big way. The small ones are good for the purpose of farming and homeowners. The big turbines installed off-shore are used for industrial and mass consumption like the supply of electricity to urban areas. It is estimated that by 2020 wind power sector would mitigate about 20% of the global electricity demand.
The growing concern for environments and the rising demand to conserve the fossil fuel for posterity has made countries to look for alternative sources of energy. In this connection, wind energy has come to forefront and is being increasingly looked upon as the major source of power. The good thing is wind is available all around the world and hence, it is one of the cheapest sources of energy.
The process of converting wind energy into other forms of energy is known as wind power. This is achieved through the wind turbines, wind mills, wind pumps or sails, and the energy, thus formed, is used in the form of electricity or any other mechanical power.
Using wind as an alternative form of energy, especially to fossil fuel, has great benefits. Apart from being available everywhere, it produces no harmful by-products. You also do not need a large area to harness it.
It is true that the amount of electricity produced by the turbines is also dependent upon the availability of good source of wind. But with the advent of technology, the turbines these days have become smaller and more powerful. While the ones used for home or farming produce one to two Kilowatt of power, the large turbines installed off-shores can produce 7 megawatt of energy. The cost of installing a 2 Megawatt turbine is around two to five millions in the U.S.
With wind power catering to a substantial part of world’s energy requirements, installation of turbines have grown by leaps and bounds in the last decade. The greatest growth in this power sector has been witnessed in China. According to some estimates, the installed capacity of wind turbines is around 200,000 MW in the world.
Catering to this growing demand, many companies work in the field of wind power. Windation is one of the companies that manufacture and install wind turbines.
