Wind on our planet is the movement of air caused by the unequal heating of large zones of Earth's surface by the sun. Today, wind energy is mainly used for the production of electricity. It is a clean and renewable energy source that can produce enough electricity to power huge areas. But if we look at the "day" before, it was the power that helped the people to travel around the globe and the main energy behind the "discovering" of new continents, so USA and Canada are formed due to the wind. And seed dispersal, as well as indirect effects on photosynthesis or insect communication are also wind energy benefits.
Wind energy, or the business of putting up a wind turbine and using the energy of the wind to generate an unreliable dribble of electricity, is a way a making a profit from subsidies. Our electricity suppliers are obliged to buy energy from sources like wind farms and to pay them more than the energy is worth. The government has fixed a high price for electricity from wind farms - much higher than we pay for electricity from traditional sources. We all pay for this though artificially high electricity bills, just so the owners and operators of the wind farm can make a nice profit. The really silly thing is that it doesn't even save any carbon dioxide pollution because wind energy is so unreliable, we have to have a conventional power station running at an inefficient level in the background to compensate for troughs in wind power.
The main advantage of wind energy is that harnessing it doesn’t disrupt natural processes or harm the environment, unlike a lot of other energy sources. To generate electricity on a large scale, a number of windmills are set up over a large area, called a wind energy farm. Such areas need a wind speed of 15kmph.
Advantages Of Wind Energy
1) Wind Energy is an inexhaustible source of energy and is virtually a limitless resource.
2) Energy is generated without polluting environment.
3) This source of energy has tremendous potential to generate energy on large scale.
4) Like solar energy and hydropower, wind power taps a natural physical resource.
5) Windmill generators don’t emit any emissions that can lead to acid rain or greenhouse effect.
6) Wind Energy can be used directly as mechanical energy.
7) In remote areas, wind turbines can be used as great resource to generate energy.
8) In combination with Solar Energy they can be used to provide reliable as well as steady supply of electricity.
9) Land around wind turbines can be used for other uses, e.g. Farming.
Disadvantages Of Wind Energy
1) Wind energy requires expensive storage during peak production time.
2) It is unreliable energy source as winds are uncertain and unpredictable.
3) There is visual and aesthetic impact on region.
4) Requires large open areas for setting up wind farms.
5) Noise pollution problem is usually associated with wind mills.
6) Wind energy can be harnessed only in those areas where wind is strong enough and weather is windy for most parts of the year.
7) Usually places, where wind power set-up is situated, are away from the places where demand of electricity is there. Transmission from such places increases cost of electricity.
8) The average efficiency of wind turbine is very less as compared to fossil fuel power plants. We might require many wind turbines to produce similar impact.
9) It can be a threat to wildlife. Birds do get killed or injured when they fly into turbines.
10) Maintenance cost of wind turbines is high as they have mechanical parts which undergo wear and tear over the time.
Wind energy is the biggest scam of the century. Per unit cost of wind farm is more than conventional source.

can some one help me? can you write a short article about wind energy please . thankyou
