Advantages and Disadvantages of Tidal Energy

SHARE

Tidal energy is a renewable energy source that is tapped from the movement of water on the earth surface. The gravitational force is the reason behind the production of electricity for use in households and industries.

The advantages and disadvantages of tidal energy over fossil fuels are quite numerous. The popularity of tidal energy is growing gradually across the world.

The article provides excellent information about the pros and cons of tidal energy. It is worth to note them before offering advice about the best alternative source of energy to choose.

Advantages of Tidal Energy

  1. Renewable Source of Energy

Tidal energy is brought about the sun and moon gravitational forces during rotation. Tidal power is renewable since the rotation of sun and moon is likely not to cease in any future.

  1. Clean and Green

Tidal power production is eco-friendly since it does not emit any form of gases that might result in the greenhouse effect. It also does not take up ample space.

  1. Tidal is Predictable

The current of the seas are predictable, and this makes it easier to construct tidal energy. The currents help to determine the turbine quality to be installed in the plant.

  1. Quite Effective

The effectiveness of tidal power is when the water flows at low speed. It enables the energy plant to produce a large amount of electricity for use as compared to fossil fuels.

  1. Long Lifespan

The lifespan of tidal energy is quite long, and the chances of generating a lot of income for the provision of electricity will be there for many years.

  1. Reduce Dependence on Foreign Oil

Harnessing of power from tidal energy plant on a large scale will probably reduce importation of oil from other countries. It will also help to conserve the environment.

  1. Protection of Coastal Region

Development of dams for harness electricity helps to protect the coastal area from high tides that sometimes causes destruction.

  1. Create Employment Opportunities

Construction of tidal energy plants has helped to create both temporal and permanent job opportunities for people in the country.

  1. Low Costs of Operation

The initial costs of constructing a tidal energy plant are quite expensive, but the running cost is relatively low as compared to other sources of energy.

  1. Effective Energy Production

A small number of tides can generate a large amount of energy that is quite effective in terms of density as compared to coal energy sources.

Disadvantages of Tidal Energy

  1. Repair and Maintenance Costs are high

The equipment in the tidal energy plant requires frequent repair and maintenance due to corrosion hence making the costs to be high.

  1. Effects of Weather

Bad weather and storms can result in hurricanes that are likely to destroy the construction of tidal energy plant. Tsunami is the worse, and it can cause a huge disaster.

  1. Long Gestation Time

Creation and development of tidal energy plants take an extended period. It will even take years to start producing power for household and industries.

  1. Destruction of Coastal Aesthetics

The view of coastlines and beaches can be interfered with by construction of tidal energy plant. It can also hurt tourism activities.

  1. Low Technology Advancement

There are few implementations of in tidal energy production plants since the technology to be used in the generation of electricity is still under test.

  1. Usefulness is Limited

Tides usually take place for about 10 hours in a day, and this feature limits the usage of the tidal energy plant.

  1. Limited Location

Potential growth of tidal energy plant is limited since it is supposed to be developed in specific areas around the globe.

  1. Expensive to Construct

The initial cost of designing and constructing tidal power plants is high. Also, the instruments for the plant require massive investments.

  1. Distance from the Grid

Electricity is usually consumed inland, and the distance from the area of production is too far. It limits the consumption of power only to the people close to the coastline region.

  1. Disruption of Tidal Flow

Tidal plants exist in the dam built across estuaries. The feature affects the flow of tides to enhance the production of adequate power for consumptions.
