What is tidal energy?What is tidal energy?

• We can use the movement of the tides, which are controlled by the moon to power the turbines, which is connected to a generator to produce electricity.

How can Tidal Energy be How can Tidal Energy be harnessed?harnessed?

• Strictly speaking, there are 2 ways in which this energy can be harnessed. One way is through wave energy, and the other is through tidal energy.

• Tidal energy involves tides coming onto the shore and, they will be trapped in reservoirs behind dams. Then, as the tide drops, the water behind the dam can be let out just like in a regular hydroelectric power plant.

Advantages of using the energy Advantages of using the energy sourcesource

• The major advantage of tidal energy is its economical benefits.

• Examples of Benefits:• It is a free renewable source

of energy.

• We become less dependent on non-renewable sources, and it does not pollute the environment.

• The tides are very predictable, and people can use their knowledge of the time of high and low tide to capture the energy produced by them.

• The tides are available year-round.

• There is no side-effect of producing green-house gasses.

Disadvantages of using the Disadvantages of using the energy sourceenergy source

• Unfortunately, there are still some drawbacks to using tidal energy.

• Drawbacks:• This might effect the eco

balance of the area where one is harnessing the power of tidal energy.

• It is only available to certain people, who live near the oceans

• It will only work if the tides are moving very high.

• We also don’t know if it is cost-effective because only a few countries are using this form of energy, and the technology used to harness the tides are very expensive.

Countries who rely on tidal Countries who rely on tidal energyenergy

• So far, only 3 countries are using this renewable source of energy, and they are: France, Canada, and China.

• Many other countries are also now experimenting with the ways to harness tidal energy, including: Russia, UK, Australia, USA, Argentina, Canada, India, Korea, and Mexico

Status of the energy source in Status of the energy source in the Philippinesthe Philippines

• There was a study, before, during 1995-1997, of the magnitudes and cost of building a tidal energy plant in Eastern Philippines conducted by a company in the Philippines and a company from Canada.

• Their goal was to find a suitable site to build a tidal energy plant. The large waves in the Pacific Ocean and Sulu Sea can generate huge amounts of electricity, even if the tides are only 1.5 tall. To test their theory, they built a model of the planned tidal plant.

• To continue in their research, a company for Japan will help the 2 companies in their research.
