Nhận biếtRead the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.
Tides are the waves caused due to the gravitational pull of the moon and also sun (though its pull is very low). The rise is called high tide and fall is called low tide. This building up and receding of waves happens twice a day and causes enormous movement of water. It is so powerful that it has caused many mishaps and resulted in sinking of ships. Thus tidal energy forms a large source of energy and can be used in some of the coastal areas of the world. Tidal dams are built near shores for this purpose. During high tide, the water flows into the dam and during low tide, the water flows out which result in turning the turbine. Here are some of the advantages and disadvantages of tidal energy. Tidal energy is an inexhaustible source of energy. It is friendly energy and doesn't produce greenhouse gases. Efficiency of tidal power is far greater as compared to coal, solar or wind energy. Its efficiency is around 80%. Although cost of construction of tidal power is high but maintenance costs are relatively low. Tidal energy doesn't require any kind of fuel to run. The life of tidal energy power plant is very long. However, the cost of construction of tidal power plant is high. There are very few ideal locations for the construction of plant and they too are localized to coastal regions only. Intensity of sea waves is unpredictable and there can be damage to power generation units. Frozen sea, low or weak tides, straight shorelines, low tidal rise or fall are some of the obstructions. This technology is still not effective and more technological advancements are required to make it commercially viable. Usually the places where tidal energy is produced are far away from the places where it is consumed. This transmission is expensive and difficult.
