Wind Energy In Spain
Wind energy: is when we are using the wind to introduce power for electricity by using the wind turbines.
The turbines are working by following few steps:
First of all, the blades catch the wind and start to move around. Then the generator changes the mechanical energy in to electricity.
After that the cables takes the electricity to the transmission line, and the computer system controls the directions of the blades.
I think wind is a good energy source for Spain, because it is located on the cost where it can have big amount of wind during the year.
Of course there are some disadvantages about this kind of source, one of them is that sometimes wind is not available in Spain, but I believe that there are many other sources in Spain which gives them energy.
Another disadvantage is that the turbines might kill the Migratory birds.
Sometimes wind turbines make some noise that’s why people don't like them.
On the other hand there are many advantages of using wind turbines. The first one is the wind turbines doesn't produce any gases so it will make our environment clean. And it's also attractive for the visitors specially the wind farms in Spain. Another advantage is that it is to easy to deliver the wind energy to the isolated areas in Spain, and we don’t forget that Spain could have the wind for free because of its location as I munched before.
