How Does Wind Power Really Work?

Wind power is going to be essential to our planet in the near future. But do you really know how wind power works? It looks easy but there are several components involved 1____________________ generating wind power. This type of power can not only save us a good 2___________________ of money on our utility bills, but it will also play an important role in 3_______________________ our planet. For many of us, wind just looks invisible and does not actually have any properties but in 4_____________________, air is a fluid that contains particles constructed of gas. We can turn these gas particles into power because as the wind gusts, kinetic energy is created, which then can be harnessed and changed over into power. Having access 5______________________ wind is very essential for this operation to work but another indispensable ingredient is the blades that are used. Their design is very 6___________________ to the effectiveness of the turbine.

The other important component is simply the size of the blade. The bigger the blade is, the more energy is seized and more power can be created for us in the form of electricity. Much also depends 7____________________ where you live to figure out the right blade size. In regions with low wind levels, small blades work better because more wind is required to push the larger turbine blades. In an area that is very windy, it is much better to use large blades in 8_______________________ to use all of the wind available. This gives you the fundamental principles of how electricity is produced from the wind. Today is a fantastic time to do as much 9________________________ as you can about wind power so you will be able to make 10______________________ decisions in the future.
