Other alternatives

Hi! This week we are going to think what other options do we have that are renovable, no like petrol, that it's going to end in a few years.

Renovable energies could be the solution for lots of problems in the present. Polution is one of them and these energies can reduct the exces of polution in the atmosphere. Look!

Solar energy and eolic energy are two exemples of that, but we are going to talk about hidraulic energy. What do you think?

This energy is based in the movement of the water when it felt. It is a good energy because our world is 3/4 of water. It doesn't pollut and it is ecologic.

If you are interested look at this!
