Wind Energy


Like any other elements that rest upon this planet, wind is one of the essential components in building an equilibrium cycle of life. The common knowledge that is brought up about wind is that it’s the only element that gives and sustains life to us humans through the production of oxygen. But what we aren’t aware of Is that the air we breathe and relish gives an outstanding source of energy.

Wind is the movement of air from an area of high pressure to an area of low pressure. According to www.nationalgeographic.com, the wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And as long as the wind blows, people will harness it to power their lives. Like solar energy, the wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments offer tax incentives to spur wind-energy development. 

Total wind power could be captured only if the wind velocity is reduced to zero. In a realistic wind turbine this is impossible, as the captured air must also leave the turbine; a turbine is a rotary engine that uses a continuous stream of gas or liquid to turn a shaft that can drive machinery.  Wind energy is so powerful that it can run and grind grains and pump water for farmers using wind turbines, wring electricity from the breeze that can run a city with the use of windmills. The town of Bangui in Ilocos Norte is one of the cities in the Philippines who is using wind energy as source of electricity and strongly promoting this environmental-friend source of energy.

  1. nice blog!. got a really good info here. one question if wind energy produce no air and water pollution and the cost of production is cheap why didnt almost all energy providing company choose this? is there any reason?

    1. Hello Arvin! Good question! Well, first of all, wind has also an unreliable factor. Some places do not have strong wind and cannot produce enough energy. Wind mills together with the land for the site is also a pricey. These are some factors that hinder companies to choose this as their main source of energy. Thanks for the comment! Happy blogging!

  7. I must say, windmills really are efficient in providing energy. I hope more of these kinds of environment-friendly technologies will be produced to better serve the needs of the people; particularly, in finding alternative ways to access/obtain energy.

  8. Nice article! It can serve as an awareness for us. Since some of us abused our natural resources, we should promote this kind of source of energy.

  10. Wind energy (wind mills) is on of the best way to produce energy in the country. Since our country is surrounded by bodies of water like seas and oceans, the wind pressure in these areas is very high which is perfect to construct wind mills that will generate alot of electricity that we consume. I just hope to see more of this environmental-friend source of energy in the Philippines in the future. :)

  11. Philippines and also the other countries should build more windmills to provide other source of energy and to lessen pollution.

  12. Local communities might need to spend a lot for them to acquire this equipments/turbines though in the long run, people would benefit from these as it would lower their electricity expenses since wind power is free.
