What is wind energy? How is it generated?
Wind seems to be the most overlooked potential source of power even in this 21st century era. However, a number of facts about wind energy need to be addressed before it is too late! Wind is a form of solar energy. Differential heating of the irregular earth’s surfaces and earth’s rotation and the uneven distribution of heat in the atmospheric layers cause wind flow. And the flow patterns of wind are again regulated by the water bodies and the vegetative covering of the earth. This wind flow produces a kinetic energy which is actually captured and harvested by using modern techniques as wind energy. The modern devices involved in harnessing wind energy are wind energy turbines and wind mills.
Facts about wind energy: Myths resolved
In spite of all the awareness worldwide about power saving and regeneration, there still persists a lot of misconception about wind energy amongst the common people. In this article we will be discussing some very important and reliable facts about wind energy which will be helpful to clear out our various doubts concerning the subject. Firstly, wind being a form of solar power is a renewable source of energy that will never get exhausted. Thus wind does never ever need to be produced and there will always be a perpetual supply of it. There is a myth among many people that a wind power plant is highly expensive to set up and it takes a lot of monetary capital to establish wind energy plants. But the nude fact is that once started up and the initial investment is done, a wind energy plant is the cheapest option of electricity generation. The maintenance cost is also quite negligible. Thirdly the saddest part of the misconception about wind energy is that people look down upon this wonderful proficiency as a very weak source of power that can hardly support even our household requirements. And here is another of the various amazing facts about wind energy. Wind power can become a massive source of renewable power if properly managed. But studies indicate that till 2005 we have used wind for only 1% of the total electricity generation in the world. But the fact is that wind energy alone has the tremendous potential to support the entire world’s requirement for electricity.
Facts about wind energy: environmental compatibility, economics and development
Talking about the environmental compatibility of the wind energy, we can strongly claim that the electricity that is generated is clean and non-polluting considering that the source being wind itself is clean. To add to this, wind energy generators have lots of advantages over the conventional power plants that are worth mentioning in this context. Compared to the conventional modern power plants wind energy converters never produce any greenhouse gas or air pollutants. Apart from saving power, wind power plants are also easy on the economy as compared to the fossil fuel plants since the former have a minimum life-cycle cost like no fuel purchasing and minimum operating expenses. However, the concerns like visual impact and avian mortality (bats and birds being killed while flying into the rotors) and noise pollution (generated by the rotor blades) are been taken care of by simple solutions like wisely locating the wind power plants and technological developments.
The economic facts about wind
energy clearly convey a very clear idea that wind as a
resource is the cheapest and can be renewed ‘n’ number
of times! The development of the wind energy generators
has seen quite a steep growth rate across the world till
