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 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.

5

• 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 source

• The major advantage of tidal energy is its
  economical benefits.
• Examples of Benefits
• It is a free renewable source of energy.

8

• 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.

9

• The tides are available year-round.
• There is no side-effect of producing green-house
  gasses.

10
Disadvantages of using the energy 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.

11

• 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 dont 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.

12
Countries who rely on tidal energy

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

13

• 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

14
Status of the energy source in the 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.

15

• 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.

16

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