Wave Energy: The Advantages and Disadvantages

Water, one of the world’s renewable sources, is so vast that it covers nearly 70% of the planet’s surface. And what’s even more amazing? Water waves have powerful and strong energy. This is a wonderful potential for humanity to obtain a renewable source of energy that could help shift to more sustainable power.

However, being able to actually harness such energy is more challenging than it seems. We often hear the good sides, are there also downsides for this? Let’s find out. Below are the different advantages and disadvantages of water energy. 

Pros of Wave Energy as a Power Source 

Safe to the Environment

Compared to fossil fuels, wave energy creates zero dangerous byproducts, such as pollution, waste, and gas. The wave energy can be sourced straight into types of machinery that are producing electricity as well as used to supply power to different power plants and generators within the area. Today, since the world is being powered by energy, a clean energy source is somehow difficult to find. 

Sustainable

Being sustainable is one of the best features of wave energy. We will never run out of waves. There will always be tons crashing down the shorelines. Compared to fossil fuels, which are slowly running out in some areas of the planet, waves will forever be there. Moreover, unlike corn products or ethanol, water waves are not limited to seasons. They can always be counted and don’t need much input from people. 

Highly Abundant

Water energy is pretty much more convenient than other energy sources. It is near to places that need its power. Cities that are near the coastal area can be very populated, hence, the community can make use of water energy as an ideal source of power. 

Easily Predictable 

This is by far the biggest advantage of wave energy against other energy sources. Wave energy can be predicted easily and can be utilized to measure the power amount it can generate. Not to mention, it is consistent and has been proven and tested to stand against other sources which are sun or wind dependent.

Multiple Ways to Obtain It 

There are surely tons of ways to harness wave energy and this is the best benefit it can offer to people. Methods that are currently used range from hydro turbines, power plants, to cargo ships equipped with huge equipment or structures that are placed into the ocean’s surface to harness wave power. 

Won’t Damage the Land Surface

Wave energy won’t do any damage to the land compared to fossil fuels as they can leave massive land holes whilst extricating energy for power sources. Wave energy is an exception as it won’t cause any damage to the Earth’s land surface. It’s also a cleaner method to extract power from ocean waves. 

Not Dependent on Foreign Companies 

If people make use of wave energy for generating power, there will be less reliance on foreign industries for fossil fuel supply. Moreover, using wave energy will give a better opportunity for people for green jobs and will help decrease air pollution. 

Cons of Wave Energy as a Power Source 

An Impact on the Marine Ecosystem 

Regardless of how clean the wave energy is, it can still lead to a hazardous impact on the ecosystem. Huge types of machinery are creating an impact on the seafloor, thus changing the sea creatures’ habitat and causing noise that disrupts marine life. Moreover, there is a possibility of a toxic chemical spill that may pollute the ocean. 

Only Ideal to Specific Areas 

Another disadvantage of wave energy is the location. Not all have easy access to it, except for towns and power plants that are situated near the ocean. Cities that are far away from the sea have no choice but to use for other alternative sources of energy.

Reliable to Wavelength

This is one of the disadvantages of wave energy as wind power is strongly reliable to wavelength and water density. There should be a consistent wave flow in order to produce the required amount of wave energy. Other areas may experience unreliable behavior of waves resulting in an inaccurate wave energy forecast. 

Slow Improvements for Technology Advancement

Since 1700, wave energy has been evolving, and despite this evolution, it is still a technology that requires to be completely enhanced. Somehow, this slow improvement is a bottleneck to future investments in this kind of energy source. Necessary components are needed to enhance its performance, such as China gate valves, control valve, piping system, etc.

Powerless Functionality During Harsh Weather Conditions 

In terms of overall performance during bad weather conditions, wave energy significantly drops. This may cause a downturn in power generation. It should endure harsh weather.

May Cause Visual and Noise Pollution 

For those living near the coastal areas, generators for wave energy are not that good. They are huge machines operating on the ocean’s surface and destroying the beauty of it. Not only that, they produce unpleasant noise pollution. 

Conclusion 

There is, without a doubt, a significant potential for using wave energy in terms of producing power as well as becoming a great renewable source in the years to come. Future advancement and research are required to enhance the stability and technology of wave energy generators. Part of this is to determine, reduce, and mitigate possible negative effects that this process has on the marine ecosystem.
