Solar energy

   The solar energy has become one of the most important factors in this world today, many people have heard about it, but don't really know how it works, and what advantages or disadvantages they can have. But it has many advantages that can be important, for example:
       First, the solar energy is free, because its energy from the sun, it just needs to be charged for a little while, and the sun energy can be converted for our use immediately.
       Second, its cheaper because now use the silicon and the silicon is one of the most common elements in the world, so we don't need to use another material for converts on electricity just we need the sunlight.
       Third, its clean and green energy that has absolutely no effect on the environment , that's mean that you save the environment, because now we can use natural resources.
       Finally the solar energy is available for all us, is cheaper, its clean and its free.
       On conclusion I think the solar energy is useful and necessary for the human life and we must to take this kind of electricity because I think is one of the best things that we can have now. We need to encourage the environmental education because I think is a future with initiative.
