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

Is a natural resource available in areas with sufficient water and once used, is returned downstream. Its development requires building reservoirs, dams, diversion channels and installation of equipment for large turbines and generate electricity. This involves investing large sums of money, which is not competitive in regions where coal and oil are cheap. However, the weight and environmental considerations require low maintenance once the focus in operation.
Hydropower is based on leveraging the water fall from a height. The potential energy during the fall, becomes kinetic. The water passes through the turbine at high speed, causing a rotational movement which finally transforms into electrical energy through the generators.

The basic operation is to harness the kinetic energy of water stored, so as to actuate the hydraulic turbines.
In the use of hydropower influenced by two factors: the volume and height of the jump to get more water carried by rivers, dams are built to regulate the flow depending on the time of year. The dam also serves to increase the jump.
Another way to increase the height of the jump is deriving water channel slope for small (less than the riverbed), achieving a greater gap between the canal and the river.
The water dam or channel penetrates the pipe where the jump is performed. Its potential energy is converted into kinetic energy reaching the engine rooms, which house the turbines and generators. Water reaching the turbine rotates about its axis, which drags in its movement the electric generator.
