Tidal energy – the alternate source of energy

Overview of Tidal energy

We are all acquainted with the high and low tides and the waves that we see in seas and oceans. We are also aware that the reason behind such waves and tides are the pull of moon and sun.

The rise of water is called high tide and fall is the low tide. This building up of waves and the receding of waves happens twice a day thereby amounting to the enormous amount of movement of water.

This movement of water produces a large amount of energy which is called the tidal energy. Tidal energy can be harnessed from different coastal areas of the world. The flow of water inside the water and the outflow of water from the dam cause the turbines to move thereby producing an enormous amount of energy.

Tidal energy is free of cost energy. Like every energy sources, there is also some advantages and disadvantages of tidal energy.

What are Advantages and Disadvantages Of Tidal Energy ?

The advantages and disadvantages of tidal energy are discussed below:

Benefits of tidal energy

1. Renewable source

Tidal energy is formed due to the flow of water which is a natural phenomenon. This source of energy is got from the waves and tides and hence there is no requirement of any payment for incurring such energy. It is an inexhaustible source of energy. It is such a kind of energy where there is no production of any harmful gases which is environment-friendly.

2. Budget Friendly

Tidal energy is not only eco-friendly but also pocket-friendly. As it does not release any form of pollutant gases like the emission of greenhouse gases on its usage, similarly it also does not require any extra money for production as it originates from tides. Other than setting up units for the energy production and their construction it doe not involve the usage of a lot of money. So it is not a burden on the pocket as it is easily available and accessible.

3. Eco-friendly

Tides are a natural phenomenon and occur due to the gravitational pull of the moon. So they would not require any separate apparatus to avail the source. Moreover, it is renewable and sustainable. That makes it eco-friendly, for they do not affect the atmosphere. Nature is not hampered due to the effect of pollutants. So that makes it not hard on nature.

Disadvantages of tidal energy

  • It is important to have oceans around.
  • Without the presence of oceans around tidal energy cannot be availed.
  • It is expensive to build.
  • There are only 20 sites that are identified with high potential. That indicates that it is very location specific.
  • It is non-continuous. There is a requirement of storage or grid-backup.
  • There is a restriction to access to open water because of barrages.
  • It can change the tidal level of surrounding area.
  • It has a great impact on fish, marine mammals and birds.
  • It also disrupts the regular tidal cycles.
  • In the tidal basins, it decreases the salinity.
  • The mud flats, an area where many birds feed are adversely impacted by the tidal energy.
  • Near the coast, it captures dirt, waste, and pollution.
  • It decreases the kinetic energy in the ocean.
