Sun is predominately the factor involved in providing solar power and wind power. Every one knows that solar energy is provided by sun. Wind power is also form of solar energy because sun is reason for developing winds in atmosphere. When winds are produced it blows in different direction around, then these winds can be used to produce electricity which can be used for consumption. Let’s read how Wind power technology actually works.

How Wind Power Works?

To understand the working of wind power, lets divided wind power technology in to further two steps for better understanding.

• How winds are generated
• How wind power/energy works.

How winds are generated.

Sun is the reason for generating winds in our atmosphere; it is interesting to know that wind power is form of solar energy. What actually happens is that sun’s heat causes the air to warm up in patches, in result some patches of air becomes warm and some patches remain cold. Hot air gets lighter in weight hence leaves it place and move towards upside, colder air patches are bit heavier there for they rushes to fill up the space which is left empty by hot air. This rapid movement of air around us produces winds which can be felt as movement of leaves on trees etc.

How wind energy works?

Wind turbine/ motor with blades are installed on the lengthy tower. When wind passes through these blades it makes blades rotate and produce kinetic energy.  Due to movement of blade, turbine is rotated which in result produces electricity. Electricity produced can be directly supplied to consumers or can be stored in batteries for later use. To produce more electricity with wind power, multiple wind turbines are installed in wind farm which produce more and more electricity in result.

Considerations for building wind power plant:

There are few considerations which should be taken care of while developing wind power plant.

• To produce more electricity, increased number wind turbines are required in wind farm.
• Bigger blade size can also help in increasing the electricity generation capacity; therefore always choose to have bigger blades.
• Only those places are suitable for building up wind power plants where strong and steady winds are present in most of the time in a day, remember more wind cross through propellers, more rotation it will take hence produce more electricity.
• Coastal areas, higher areas, top of the mountain are best areas for developing wind power plant as it will encounter more wind at such altitudes.
• To receive satisfactory performance from wind power plants it should be located where it face about minimum of 25 Km/p wind speed. This speed has shown reliability in past projects. Lower wind speed can also provide electricity how ever performance with consistency may suffer.
• Caravans, and boats can also install small wind power generators to keep their batteries power alive.
• Grid should not be build far from wind far, as this will increase costs of wire to provide electricity produced by wind grid station. Keep wind plant closer to grid station for cost effectiveness.
  
  

  Advantages of Wind Power
  

• Wind energy is renewable form of energy and can be used over and over again for producing electricity.

• Wind energy is free, clean energy and does not require any fuel to operate; only wind is required for rotation turbines for producing electricity.

• It is friendly to environment and does not produce any green house gasses, or carbon emissions. It does not contribute in global warming.

• It does not waste land, normally huge land is involved in developing wind farm, and land beneath wind farm can be utilized for farming and other productive work.

• Wind farms normally occupy wide land, rotating wind turbines makes entire scene very pleasant looking hence attract tourists from all parts of the world

• Wind farm can be useful to provide electricity in rural areas, where other type electricity forms are hard to reach.
  

• Wind energy is very cost effective, after initialization of wind energy plant; it does not require more cost to run it.

• Wind power generators are efficient in producing electricity. Wind farm in west Victoria, called challicum provides enough electricity for 25000 homes.
  
  Disadvantages of Wind Power

  
  
  • Do you global warm winds are no more predictable, unpredictable climate changes have been noticed through out the world.
    
    
  • Suitable areas for building wind farms are to hard find, normally wind farms are formed on coastal areas which are expensive then other areas.
    
    
  • It can be dangerous for birds especially when group of birds are migrating, it can kill birds when birds hit propellers of wind turbine.
    
    
  • It occupies huge land for building wind farm.
    
    
  • It can affect signal receptions of cellular communications and telephone systems if wind farms are nearby.
    
    
  • Winds farms can be noisy, it produce constant sound of wings movement which can make life hard for neighborhood.
    
    
  • Wind farms can prove very expensive if it is not locate near end user or grid station, homes. Connecting wires between wind farm and homes makes it very expensive.
