Are there any tidal power plant in the Philippines?

As I am researching power plants and the electrical network in the Philippines I did not found any tidal Rance power plants. With so many islands, 7.168 in total, it is amazing to see that this country has not searched more intensive into the cheapest energy. I like to get to know more people who are interested in ocean power energy.

How much energy is currently produced using hydroelectric power?

the amount of energy a hydropower plant produces depends on two factors:

1-how far the water falls

2-Amount of water flowing in the river.

Exemple

From talking to person who operates the dam in our area, we learn that the dam is 10 feet high, so the water falls 10 feet.We contact the United States Geological survey, the agency in the U.S. that measures river flowing, and learn that the average amounr of wather flowing in our river is 500 cubic feet per second.For the dam in our area lets say we buy a turbine and generator with an efficiency of 80%. Formula

Power=(height of dam).(river flow).(Efficiency)/11.8

Power: the electric power in kilowatts height of dam :the distance that the water falls measured in feet

river flow: the amount of water flowing in the river measured in cubic feet per second.

efficiency:how well the turbine and generator convert the power of falling water into electric power. for older ,poorly maintained hydroplants this might be 60%(0.60) while newer hydroplants this might be as high as 90%(0.90).

11.8: convert units of feet and second into kilowatts then the powe for our dam will be.

Power=(10 feet).(500 cubic feet per second).(0.80)/11.8

Power=339 kilowatts

and the energy in a year will be

Energy=power.(time)

energy=(339 kilowatts).(24 hours per day).(365 days per year)

energy=2969640 kilowatts.hours

How much energy can a tidal facility produce in one year?

Sihwa Lake Tidal Power in South Korea generates 250 MW of electricity, and has been in operation since last year. Korea has plans to begin construction of a 1 GW tidal power plant in 2017.

Since a watt is equal to one joule per second, a gigawatt is 3.16x10^16 joules per year.

Theoretically, much larger tidal generation facilities could be built, but there are practical economic and environmental considerations to factor in that.

Why was the Bay of Fundy picked as a possible site to build a tidal power plant?

Because they have the largest tides in the world with a difference of as much as 48 feet between low tide and high tide. The greater the difference, the more energy can be derived from the change.

Which countries use tidal power?

  • The first tidal power station in the world was built in France, at La Rance, in 1966. It has a capacity of 240 MW (MegaWatts).
  • The largest in the world is the 254 MW Sihwa Lake in South Korea (2011)
  • The first in North America is in the Bay of Fundy, Canada (1984, 20 MW)
  • Russia has a small tidal power station on the Barents Sea (2006, 1.6 MW)
  • South Korea has stations to open in 2013 (90MW), 2017 (1320 MW), and three more all more than 100 MW each.
  • Scotland is opening one in Islay in 2013 (10 MW)
  • India begins construction in 2012 on a 50 MW tidal farm in the Gulf of Kutch.

Geothermal

Why is geothermal energy so important?

It is clean, free and green. In other words, it uses the heat from deep below the earth to generate electricity that has no carbon dioxide emissions, which are harmful to the earth and are causing global warming.

Geothermal energy, and green technologies like it, are important because they are low-risk, low-impact energy sources for us to use without polluting the environment. Geothermal Technology is better for the environment and your home. There are many advantages of Geothermal Technology. The underground loop carry warranties of 25 to 50 years! According to the U.S. Department of Energy, if just 100,000 homes converted to a geothermal heating and cooling system, carbon dioxide emissions could be reduced by 880 million pounds.

How is tidal power made into energy?

The coastline has to be suitable, for example a large bay with a narrow outlet to the sea. Some kind of barrage or dam is erected there which will allow the incoming tide to fill the bay. When the tides come in or out the water moves fast through the narrow opening. There you can build a barrage, like a dam, which will allow the water to move in and out. Turbines in the barrage will then spin in the moving water and generate electricity which can be fed into the grid.

How do generators work?

Generators work by changing mechanical energy to electrical energy. It can be done by spinning an armature (one of the electrical components of a motor that contains conductors) through a magnetic field.

Generators are based on the principle of electromagnetic induction. This electromagnetic effect induces voltage and current in the moving conductors.

Is tidal energy better than solar energy?

They are both good. They both produce electricity without any carbon emissions, so they contribute nothing to the problem of global warming. They are both renewable, which means they don't cost anything to run, apart from day to day maintenance, and the power continues to come even after we use it. Both have disadvantages: solar needs the sun to shine, and tidal energy only happens a few times a day and only in suitable locations.

How does using tidal energy effect the environment?

Tidal energy generally uses movable barrages or dams across the mouths of rivers, where there is room for large amounts of water to be held back from the high tide. This may cause problems for the movements of fish, but there should not be much more than that. The water held back is no higher than the normal tides.

How much energy does tidal energy produce?

The energy created in a tidal energy system is dependent on the volume of water and the force it supplies to the turbines as it flows out. The potential energy contained in the water contained in the catchment of the tidal basin is:

E=1/2 Apgh2
where:

  • h is the vertical tidal range,
  • A is the horizontal area of the basin,
  • ρ is the density of water = 1025 kg per cubic meter (based on the range of sea water densities between 1021 and 1030 kg per cubic meter)
  • g is the acceleration due to the Earth's gravity = 9.81 meters per second squared.

The factor 1/2 occurs in the equation as the water velocity through the turbines decrease from 100% downwards as the height of water in the basin decreases.

How is tidal power harnessed?

Tidal power is harnessed by constructing a(n) dam across the mouth of and estuary or a bay.
The power of the moving waves and tides are harnessed by turbines which produce electricity. This is fed back into the electricity grid and used to power factories and homes.thetidal energy is tored in waves power.

Tidal Power

What is tidal energy?

Tidal energy is the energy produced by utilising the flow of tides in the ocean. tidal energy is the movement of the sea which turns turbines inside a kind of dam which goes across a river
Tidal energy is considered to be a renewable source of energy since it only uses the energy from the changing of the tides instead of burning or consuming any form of energy source. It is also considered to be inexhaustible because tides always rise and fall due to gravity.
Tidal power captures the energy of moving water masses due to tides and uses it to generate renewable electricity. A dam or barrage or underwater turbines are built across the estuary of a river. The river funnels the tides into narrow channels where the speeding water turns the turbines.

Tidal energy is the energy obtained from the movement of tides. If harnessed properly it can produce up to 80% of the world's electricity needs. One type of tidal power station has gates built over estuaries, and the water enters from one side of the gate and while exiting the other gate it passes over a turbine. The potential energy of the water turns the turbines as it flows out and this is used to make electricity. Because it relies on tidal differences and certain geographical requirements, only some places are suitable. This design can cause environmental concern as the aquatic life of the estuary can be harmed by the unnatural rush of tidal waves.

Most projects that I have seen use something similar to a hydro electric dam. The water is channeled as the tide goes out and later as it returns so that it spins turbines to produce electricity.

Another method uses an upright chute anchored on the bottom. As the tide comes in it fills in around the chute finally spilling over its top edge and spinning a turbine inside (near the top). Later, when the tide has gone out valves open in the bottom allowing the contained water to spew out spinning a turbine near the bottom.
