theory to the test energies by david morales

definition:

It is that which is obtained from the use of kinetic and potential energy, stream of rivers, waterfalls or tides

operation:

•The water falls from a dam to where is the turbine.

•The water passes through the turbine and rotate to.

•They are connected to a generator to produce electricity

Advantages of hidroelectric:

•Needless fuel renewably used.

•It is clean and does not pollute the air or water.

•The maintenance and operating costs are low.

•A water turbine is a simple machine, efficient and safe, and requires little oversight

Disadvantages of hydroelectric:

• The capital cost per kilowatt installed is often very high.

•The construction of these plants takes time more than a thermoelectric

•The dams affect water courses, cause erosion, and general affect the localecosystem

Tidal energy is produced by the movement generated by tides, this energy is harnessed by turbines, which in turn moves the mechanics of an alternator that generates electricity, finally the latter is connected to a central ground that distributes power to the community and industry.
By not consuming fossil elements nor gases that help cause the greenhouse effect. It is considered a clean, renewable energy. Among its advantages being predictable and have a secure supply potential varies not momentous year, only limited to the cycles of tidal currents.

The installation of this type of energy is performed in deep rivers, estuaries (estuaries) of river to the ocean and under the latter taking advantage of ocean currents
