TIDAL POWER
Tidal energy is a renewable source of energy which is created when the power increase throughout the rise and fall of tides. Engineers initiated to use tidal movement to produce electricity in the area where there is tidal range like high tide and low tide. As the process includes converting tidal energy into electricity, all method requires special generators in order to turn the tidal energy into electricity.
At present, there are only three numerous ways that can produce tidal energy; tidal lagoons, barrage and tidal streams. All tidal energy generator requires turbines to be placed in the tidal streams, barrage can be build and formulate opposite the rivers or bays. Barrage is one of a tidal energy generator type which uses a huge dam, the water is liberate once the barrage’s turbines created energy when the tide arise. The energy which is being used in the wave machine is kinetic energy, the kinetic energy takes play a role in moving the movement of water.
The environmental affect which causes from barrage system is very momentous. As the tidal rage is entirely confusing, plant and animal life may be harm as the water level in the tidal lagoon changed. Moreover, the organisms living may be changes as the salinity is low. For instance, fish is stagnant in the tidal lagoon while the turbines move rapidly in barrages. Using barrages may harm marine and other living organism as there is a high chance to be caught in blades. Since the food source they have is restricted, living organism will find new living place for themselves. Moreover, the cost of barrage instruction is much more expensive than any other tidal energy generator so considering to use other tidal energy generator should be one of my concern. Even though no fuel costs is needed, it cost a lot of money to construct one dam and to set up all the machines.
Tidal lagoons is the other type of tidal energy generator which function distinctly like the barrage system. However, it is possible tot construct tidal lagoons along the natural coastline. A tidal lagoon power plan produce continuous power whereas the turbines function to fill and emptying the lagoon.
Environment impact of tidal lagoons do not presently occur a lot. Tidal lagoons can easily be build using natural materials such as rock. At low tide, low breakwater or sea wall will sometimes appear and go under water at high tide. Furthermore, animals are able to swim around the structure without any issues and tiny organisms are able to swim inside it as well. Since large organisms like shark are not able to perorate the lagoon, finish can a highly chance of thrive. Lastly, the energy output which the generator is needed used tidal lagoons and it turns out to be really slow.

ADVANTAGE AND DISADVANTAGE FOR TIDALS WAVE
Advantage:
1. Tidal current are predictable Tidal current are predictable which means that it is possible to control the electricity that is being generated. 2. Tidal waves is a renewable energy source. The gravitational fields from the sun and moon which provides energy is reusable 3. Environmental friendly Tidal waves do not take up a lot of space and to not emit any greenhouse emission related. 4. Effective at low speeds It is feasible to generate electricity at low speed as water has 1000 times higher density than air. 5. Electricity can be generated anywhere Electricity can be generated anywhere at any time as long as there is waves and water. |
Disadvantage:
1. Environment effects. The environmental effect of tidal power plant is not surely determined. 2. Expensive The cost of construction is very high 3. Limited to be construct close to land only Tidal power plant can only be constructed nearby land. |
Environmental implication:
The environmental impacts which causes by tidal waves associated with different factor. For instance, some of barrage systems include destruction of habitat, potential electromagnetic interference and potential acoustic pollution is involve with the non-mentary costs. Moreover, hydroelectric and hydrokinetic systems can assassinate marine life and habitats. As it will doubtlessly require large expanses of ocean space for wave energy installations, this may damage marine life residents and dissolved oxygen which were produce from the waste heat of the machine may kill fishes and organism in the area nearby.
Moreover, certain tidal energy technologies are settled at the mouths of ecologically sensitive estuary systems which makes it possible for changes in hydrology and salinity that is will surely affect animal and plant life. Lastly, even though global warming emissions for tidal power is preparatory, it is estimated that there is 0.05 pounds of carbon dioxide is equivalent per kilowatt hour below. As a result, the potential for global warming emissions for natural gasses that use to generated electricity is high.
