ENERGIES - The hydraulic energy

Our energy, hydraulic energy consist in use the kinetic and potential energy of water to produce energy for people. Its advantages are that are a green energy because it doesn't pollute,  is much cheaper than oil.
Its disadvantages are that we need to flood large extensions of land , because we need water that moves  the turbines of the reservoirs to  produce the energy and with this action we lose a lot of ground that we use to build houses. The most important hydraulic energy its use in Brazil, Argentina,United States, China .
These are some of the main features of this energy that I wanted to explain. Soon my team will work on this energy with many more features. I think this is a good summary what do you think?
