Hassan Al-Najjar (solar energy)

Solar Energy

Nowadays, many countries depend on solar energy.  In fact, we take the solar energy from the sun, and that could decrease using the electricity.  However, there are three advantages of using solar energy, which are, renewable source.  For instance, at night the sun disappear because of clouds, but it returns in the morning because of the sun.  Also, the solar energy heat from the sun and it is free, so we don't need a lot of money to spend electricity.  Finally, solar energy is unlimited source.  For example we may haven't enough of electricity, however the sun will not disappear until we all die.
