Tidal Power
Technology is available to exploit the potential energy formed by tides for the generation of electrical energy. The basic structure is a barrage or dam built across a river estuary or at the mouth of a bay. This dam is similar to that used in hydroelectric power plants built across flowing rivers. At regular intervals along the dam, gates and turbines are installed. When the tide is rising, the gates are opened. This allows water to flow into the area behind the barrage, raising the water level there. When the water has reached its highest level, the gates are closed. Then the tide drops on the seaward side, and this trapped water is several meters above the sea level. The gates are then opened, allowing the water to discharge out. The force of the flow turns the turbines and generates electricity. It is also possible to use tidal energy when the water flows in the other direction - through the gates into the estuary from the sea.
In this way, four periods of energy production are possible every day, since coastal regions experience two high and two low tides in just over 24 hours. In order for practical amounts of electricity to be generated, the difference between high and low tides must be at least five meters. Tidal power is renewable, non-polluting, and contributes no greenhouse gases to the atmosphere. This kind of system can provide a useful energy supplement to other sources in an era of diminishing fossil fuel reserves.
The passage states about the benefits of the tidal energy and how a process of engendering the tidal energy works. But, the lecturer says that what are the negative consequences after we implement it.
First, the passage states that this kind of system can provide a useful energy supplement to other resources in an era of diminishing fossil fuel reserves. But, the lecturer contradicts it and says that the tidal energy only provides fraction of enery that we need only if a barrage or dam is built in a proper region. It can't affect much to the total energy we reserve.
Second, the lecturer states that a dam or barrage affects the quality of water. So that it affects wildlife marine animals. It also affects the natural vegetation and fishes who naturally migrate in the river is hampered by it. It stimulates the growth of red estuary so that it affects fishes and birds.However, the passage says that tidal power is non-polluting and contributes no greenhouse gases to the atmosphere.
Finally, the lecturer says that it affects the economy of a region where a dam is built.A fishing boat can't navigate between the estuary and the sea. But, the passage doesn't state anything about it.
To conclude, the passage says that the tidal enery is our new source of energy and it is very beneficial compare to older fossil fuel enery resources. But, the lecturer says about the drawbacks of it and how it will affect marine animals and economy of that region.
