Question

Under which of the following resources can tidal energy be put?
A.Replenishable
B.Human made
C.Abiotic
D.Non recyclable

Answer 1

Hint: Tidal energy is a form of energy which can be harnessed through the tidal waves. It is converted into electricity or usable form of energy. It can pose as a good alternative to the non renewable resources like fossil fuels.

Complete answer:
Tidal energy is a renewable or replenishable source of energy as it is inexhaustible in nature. It is generated when tidal barrages or dams are constructed across a narrow opening to the sea. Water rushes into the dam as the sea level rises, which moves the blades of the turbines attached at the opening of the dam.

Tidal energy can prove to be very advantageous. It is environmentally friendly, provides a long term economy as, once, a tidal-power system is up and running, it’s comparatively cheaper to maintain. It is energy efficient. Tidal power is called a green energy source, as it emits zero greenhouse gases. It also doesn’t take up a lot of space. It happens to be very reliable. As the sea currents are very predictable, with well-known cycles, it is easier to construct tidal energy systems with the correct dimensions, thus making the source of energy very reliable. The lifespan is very long. For instance, La Rance tidal barrage power plant, constructed in 1966, still generates large amounts of electricity up to this day.

Hence, the correct answer is option (A).

Note:Tidal energy has its own disadvantages. High tidal power plants make high construction costs very necessary. There is an adverse impact on marine life forms. It can’t be set up anywhere as the intensity of sea waves is variable.
