5 Advantages and Disadvantages of Tidal Renewable Systems

Tidal renewable energy is energy gotten from ocean tides and currents. This eco-friendly technology is slowly gaining ground as a better form of renewable energy, compared to other types. It uses currents to drive installed turbines, to produce electricity. Water experts promote this way of producing energy that doesn’t pollute the environment.

If you don’t quite know yet, how tidal energy works, take a look at this explainer video below before we will get into details of the pros and cons.

Tidal energy has its benefits but isn’t without its disadvantages. Here are five advantages and disadvantages of tidal renewable energy.

Advantages of Tidal Renewable Systems

Eco-friendly and Clean

Tidal energy is environmentally-friendly and promotes a cleaner planet. Just like other renewable systems, it doesn’t emit greenhouse gases that endanger ecosystems.

Predictable Technology

With tidal renewable systems, it is easy to construct tidal fences, baggage, and other tidal energy systems correctly. This is because the type of current they’re exposed to is one that is already known.

Continuous and Sustainable Energy

It is impossible to run out of tides. They are a constant just like the sun and moon. Therefore, tidal renewable systems are always continuous and sustainable for even decades ahead.

Low Maintenance Cost

After construction, maintenance of tidal renewable systems is very low. Tidal energy plants are long-lasting and don’t require regular operational maintenance for smooth running.

High Energy Output

One of the advantages of tidal renewable systems is that they have a high energy output, even when the tides are moving at a slow speed. This inherently makes it a highly efficient energy source.

Disadvantages of Tidal Renewable Systems

Expensive Technology

Tidal renewable technology is the future of renewables, but it is new and very costly. The construction of tidal power plants takes up a lot of money because they are mostly carried out on an extremely large scale. Even the equipment used in the production of these systems involves a lot of funds, which makes it an expensive energy project.

Environmental and Marine Life Impact

Once installed, tidal fences and barrages affect the free flow of water. This in turn upsets the marine ecosystem and the blades from these turbines can even kill some of these aquatic animals. Aside from that, the environment is impacted by tidal renewable systems since they have similar effects to hydroelectric dams.

Scarce location

The construction of tidal plants is very ambiguous. The location where it will be installed needs to be in line with specific requirements. This poses a problem since these plants and turbines need to be installed by the coastline or areas surrounded by a large body of water.

Irregular Energy Production

Although tidal energy is predictable, it doesn’t guarantee constant energy production. It is in fact an intermittent energy source. Tidal renewable systems produce energy whenever the tide is high, which doesn’t satisfy the energy demand. This renders it an unreliable source of energy.

Relatively New Technology

Tidal renewable energy is a new technology that is slowly growing. However, there is still insufficient research on it. It is still considered theoretical and the few existing plants are just prototypes. A lot of research and funds need to be invested in tidal renewable energy before it can become a popular energy source like solar or wind power renewable energy.
