Wind Energy Has No Limits
Nature has gifted mankind with plentiful resources to live life in a better way. But humans haven’t taken their full advantages till now. Wind is very potential source of energy that is available everywhere in the world for free. It is the unlimited source of energy that if conserve properly can create energy out of it. Wind power has been used for many purposes since years, such as sailing, grinding grain, and for irrigation purpose.
The source of the wind is the heat of the sun. When the sun rays fall on the surface of the earth, it warms up every part of the earth’s surface, such as soil, water, sand and rock. But it can’t heat up each part equally and in same speed, as every part of the earth’s surface has a different capacity of absorbing, retaining, reflecting and releasing the heats. During the day time, the amount of heat increases while in the time of night it decreases. As a result of which certain part of the earth’s surface get warmed and cool down at different level. The hot air increases by decreasing the atmospheric pressure near the Earth’s surface that draws in cooler air to replace it and this air movement is called wind.
There are lots of energy sources which create pollution, such as fossil fuel. Here comes the best thing about using wind energy, use of wind energy doesn’t create any kind of pollutant that can affect environment. Moreover, unlike other energy sources, there is no shortage of this energy; it is easily available to all without any single penny. Wind energy has been used since years for various purposes by people, such as: to make electricity people have been using wind turbines, for mechanical power using wind mills, for pumping water or drainage or sails to propel ships using wind pumps.
Finally, it can be said that in assessment to the environmental effects of traditional energy sources, the wind power has relatively minor environmental effects, as it consumes no fuel and thus, releases no air pollution. The energy that are used to build and convey the materials for making a wind power plant is equal to the new energy generated by the plant within a limited period of operation.
However, in certain location, planting a wind farm may lead to some dangerous situations to birds and bats. However, studies have revealed that the birds killed by wind turbines is not very high in comparison to the number of those that die due to certain other ways, such as: generating electricity and particularly by the environmental impacts of using non-clean power sources. The production of fossil fuel kills more birds as many per unit of energy generated than the wind-farms. At last, we can say that using natural resources to produce energy is always a great thing, but not all natural resources are available in unlimited portion, so using them in proper way not only help us to get what we need but also will do welfare to the whole mankind.
