In a study conducted on wave energy, energy from a wave measuring about 3ft long and 10ft tall can light around 1000 bulbs! As the technology improves and the demand for renewable energy technologies increases, the costs of investment and construction of wave energy technology are expected to decrease. Lots of big cities and harbors are next to the ocean and can harness the power of the waves for their use. There is maintenance to be taken care of. This is because the wave frequency and power vary from place to place. Another benefit of using this energy is its nearness to places that can use it. So, we can learn that the stronger the winds are, the higher the energy transmitted to the waves is. Some forms of green power energy can function and generate power even in harsh weather conditions. (And How To Keep Them Away). Working with other renewables. The best thing about wave energy is that it will never run out. This is a limiting factor for countries that do not have a shoreline. Below are some of the most important disadvantages of tidal wave energy. These issues may come up with setting up other energy production plants. The gravitational pull plays its role and raises the water level when is then forced by the wind to move forward, which is why these waves are usually called wind waves. 1. There will always be waves crashing upon the shores of nations near the populated coastal regions. In this article, we can grasp the meaning of wave energy. See Related: Pros and Cons of Nuclear Energy. This energy form has little to no impact on the land. Costs; The initial cost of setting up and operating a tidal wave power plant is very high. Installation costs are quite high; Only energy is produced as long as there is a gap between the water levels at the top and bottom of the dam wall; Only power plants may be installed to produce electricity from this energy in locations which meet the geomorphological needs necessary for that energy and which have a very high tidal difference (about 5,5 m); Its construction can have great environmental impacts due to the creation of the reservoir. However, energy production is continuous. The first benefit of offshore wave power is that there is a larger energy potential in wave’s energy. Waves are just a part of our world and they will be always crashing on the shores. Thus, for bulk fluids (liquids or gases) the waves are longitudinal waves. Can You Recycle Frying Pans? Yes, Solar Panels Produce Pollution, Here’s How? These drawbacks provide a reason for why wave energy may not be convenient to use despite the plenty and vast availability of water bodies. It is not as clean as it seems. But, it is essential for us to understand that both forms of energy are actually a type of ocean energy. Europe in 2020 has targeted to incorporate 20% wave energy in its total consumption of power. Referring back to fossil fuels energy generation, we discover that this energy is toxic to the environment. Wave power is almost consistent than solar or wind power. (And How to Keep Them Away), Do Deer Eat Peonies? Wave energy may vary due to wave speed, water density, and wavelength. (And 5 Ways to Dispose of), Is Junk Mail Recyclable? Thus no pollution is caused. Equipment that is exposed to rugged oceanic conditions 24/7 can lead to damage to wave equipment and to corrosion from salty seawater, requiring maintenance. This is because the probability of winds blowing over the ocean’s surface is high. The energy production is definitely constant and viable. Some forms of solar energy can be influenced by clouds in the sky. Unlike fossil fuels, which are running out, in some places in the world, just as quickly as people can discover them. So, this makes the production of wave power widely available. Hence wave energy is not viable for everyone. Many of our nations have a coastal region. Now, we have an idea of the production of this energy. It is then, not a clean energy source for us all. This means that the production of power from this form of energy may not diminish. To understand the production of wave energy, we first need to know what wave energy is. This means that government officials and private companies that want to invest in wave energy sources have to take into account and consider the needs of those they may be disturbing. It is free. Dependence on foreign companies for fossil fuels can be reduced if energy from wave power can be extracted up to its maximum. WHAT IS IT? Below is the definition the five types of marine energy, how it works, and the advantages as well as disadvantages of each energy. The biggest disadvantage to getting your energy from the waves is location. Wave energy is the energy harnessed from oceanic waves and is produced when the wind blows over the surface of the sea. Required fields are marked *. We discover that power can drop during a rough storm in the sea. Because wave energy is still in the developmental stage, it is very costly to build wave devices. So, as you are harnessing energy from the changing tides, you don’t decrease the amount of energy the tides can produce in the future. 101 Unbelievable Facts about Solar Energy. Additional renewable energy resources include geothermal energy, hydrogen energy, tidal energy, wave energy, and biomass energy. Wave power will combine with solar energy to power a 2MW solar farm and 2MW battery storage systems for the island. Also, not to mention that this energy resource is diminishing. The author also explains significant coverage of possible environmental effects associated with wave energy conversion. (And Ways To Protect Peonies), Do Deer Eat Roses? Thus, if we only have our electricity produced from fossil fuel energy, we may suffer a huge blow when it gets depleted – and gets banned. If you want to go deep into the topic then The Author Michael E. McCormick ( is the Corbin A. McNeill Professor of Naval Engineering at the U.S. Who knows what the future holds for this newly-discovered energy source. All these costs are really very high. As discussed earlier, we learned that water covers about 70 percent of the earth. It is safe, clean, and one of the preferred methods to extract energy from the ocean. 784 Words 4 Pages. Your email address will not be published. Despite its benefits, wave energy does have some negatives attached to it, namely: Stand out generators – wave energy generators can ruin the visual beauty of oceans. Placing wave power plants offshore could potentially minimize the negative environmental effects wave power has on the environment. So, we can learn that the stronger the winds are, the higher the energy transmitted to the waves is. These waves are neither a form of longitudinal waves or transverse waves. Wave energy and power facilities dominate the water landscapes with their presence. Cons of Wave Energy . Also, we learn why this form of energy may not be as popular as other forms of energy such as hydropower. The waves formed are either the longitudinal waves or the transverse waves. Not only is that, despite the costs, the ocean is also a source of absolutely clean and renewable sources of energy. Wind power is highly dependent on wavelength, i.e., wave speed, wavelength, wavelength and water density. This benefit makes it more reasonable to generate electricity from wave power. They also generate noise pollution, but the noise is often covered by the noise of waves, which is much more than that of wave generators. No waste products are produced. Hence, considered a green form of energy. The energy in waves comes from the movement of the ocean and the changing heights and speed of the swells. This is because of the abundance of water bodies. In today’s energy-powered world, a source of clean energy is hard to come by. Using the power of the tides, energy is produced from the gravitational pull from both the moon and the sun, which pulls water upwards, while the Earths rotational and gravitational power pulls water down, thus creating high and low tides. Wave Energy Disadvantages. Tidal energy’s source is a result of the effects of the sun and moon’s gravitational fields, combined with our planet’s rotation around its axis, which result in low and high tides. There are, however, many disadvantages to this energy source as well. We just learned that fossil fuel demand is high in most of our countries. Unlike some fuels, we cannot run out of waves and that’s why it is considered to be a renewable energy source, just like the sun or wind. Significant amount of energy can be produced. Coastal cities tend to be well-populated, so lots of people can get used to wave energy plants. These occur within the depths of the ocean. Also, we can deduce the limiting factors in the production of wave power. Oceanic storms such as hurricanes are particularly damaging t… The biggest advantage of wave power as against most of the other alternative energy sources is that it is easily predictable and can be used to calculate the amount that it can produce. Once this cycle begins, wave energy is bound to become a booming industry. There is a need for green energy in most of our countries, this need may lead to looking for alternative renewable energy sources such as wave energy. We can find out the reasons why some countries generate their power from this energy resource for commercial use. For this reason, tapping of wave energy can only occur in sites that have strong waves coming towards the shores. This form of energy has a lot of potential. According to the UK Department for Business Innovation & Skills, Scotland and Japan now both have wave energy generators producing electricity for their local communities. This is because the waves will be travel with a high frequency and power. We are aware that the winds generate wave energy in the oceans. It is also a clean form of energy since it does not need the burning of fossil fuels for generation. The wave energy is consistent and proves much better than other sources that are dependent on wind or sun exposure. Learn how your comment data is processed. Even though the water may cover the sound, the sea life is prone to suffer from it. Now we have an idea as to why wave energy is beneficial to us. In the future, many of our nations may establish a fossil fuels ban which will have hazardous effects on the environment. Thus, environmental-friendly. Wave energy generators may be unpleasant for some who live close to coastal regions. The most important thing that we must remember is the fact that the oceans are nearly the largest source of energy. 1) Tidal Energy And also he provides a separate treatment of several electro-mechanical energy conversion techniques. So, landlocked countries or cities are unable to benefit from this source of renewable energy. 1. Thus, improving the supply of power and the environment. This site uses Akismet to reduce spam. 4. As clean as wave energy is, it still creates hazards for some of the creatures near it. Thus it may leave huge holes in the ground and eventually, the land becomes barren. Thus, energy can be harnessed continuously. We may often confuse wave energy from tidal energy. From various studies and calculations, it is interesting to know that wave energy is stronger near the coast than in the ocean. Various parts of the world may experience strong winds in the ocean. In addition to this, the possibility of toxic chemicals from the wave energy platforms may leak or spill into the water. Because of its source, wave energy is not a viable power source for everyone. The biggest disadvantage to getting your energy from the waves is location. Only power plants and towns near the ocean will benefit directly from it. 1. We all know that water covers around 70% of Earth. Some governments have even gone ahead to establish a target on fossil fuel ban in the future. What we may also not know is that not all areas with shorelines can harness wave energy. Your email address will not be published. It has its drawbacks as well. Sometimes the waves can be so strong that they might severely and irreparably damage the equipment. The wave energy platforms installed in the water may obscure the natural and beautiful view of the ocean. This benefit allows the nations with access to the coast to choose the most economical way to tap the wave energy. It is because waves are almost always in motion. Fossil fuels, on the other hand, have huge land impacts. They can get stuck in the blades of the turbine unknowingly which is life-threatening. Wave energy, also known as ocean wave energy, uses waves generated by wind to produce power, making it easily and continually available. Thus wave energy provides an inconvenience to these marine vehicles. Marine life may face interruption too through noise pollution or changing the habitats of organisms that live near the shorelines. The energy in the wind is thus transmitted to these waves. Unlike fossil fuels, which cause massive damage to land as they can leave large holes while extracting energy from them, wave power does not cause any damage to the earth. For example, waves reaching the shore can be used like a piston to push air up and down a large pipe. The areas of greatest potential for wave energy development are in the latitudes with the highest winds (latitudes 40°–60° N and S) on the eastern shores of the world’s oceans (which border the western edges of the continents). One of the most significant disadvantages of using renewable energy resources is that the primary source of generation is unpredictable. This form of energy has great future potentials. It would also become the most sought after source of sustainable energy. Also, just setting up a mill will not do. This is a benefit that many of our countries with a coastal shoreline should embrace. Aside from the advantages, wave energy is also accompanied with several disadvantages. It is so huge that just along the shore, the power density is approximately 30kW to 40kW per meter of a wave. Waves generated by the wind are used to convert into energy. This may explain to us why it is not widely exploited as other energy generation methods. It is truly enormous. DISADVANTAGES OF WAVE ENERGY Environmental Damage. In most of our countries, the demand for fossil fuels is high. For this reason, the extraction of fuels is usually from underground. As the winds blow over the ocean surface, they form waves. Because the source of wave energy is restricted to oceans and seas, it can’t be relied upon to serve the entire population of a country. Some of the disadvantages of tidal energy are: High tidal power plant construction costs; Negative influence on marine life forms; Location limits; The variable intensity of sea waves; Although not widely used, tidal energy has the potential for future electricity generation. They have to seek alternative clean energy sources. The power plants harnessing the power could be put offshore. (And Ways to Reuse Old Lighters), 10 Different Alternative Sources of Energy, Can You Recycle a Mattress? Energy production from the waves requires a huge setup. 1) Environmental Effects. The disadvantages of wave energy include intermittent power generation, visual impact of devices, location-reliant devices, and high cost of construction, maintenance and distribution. The amount of power that can be produced from the waves is absolutely enormous. These machines disturb the seafloor, change the habitat of near-shore creatures (like crabs and starfish) and create noise that disturbs the sea life around them. This is due to vehicle and industry consumption. Landlocked nations and cities far from the sea have to find alternate sources of power, so wave energy is not the clean energy solution for everyone. The good thing about wave energy is that it provides an alternative method for power generation. This study helps us to picture how wave energy is of use to us and future generations. Wave energy is a source of power that comes from the endless march of the waves as they roll into the shore then back out again. It is renewable. Image: http://commons.wikimedia.org/wiki/File:WD_side_princip.JPG. Marine energy has several types of energy, there are tidal energy, wave energy, ocean current energy, ocean thermal energy, and osmotic energy. The large equipment installed in the ocean can cause a massive disturbance to the seafloor. Although there are ebbs and tides, the average motion always remains.

For … Wind energy is not always possible even when turbines could be spinning due to the current limitations of that technology. They require no input from man to make their power, and they can always be counted on. The production of wave energy is believed to be among the most benevolent methods of generating electricity. These are two different forms of energy. Compared to nuclear reserves and fossi… Disadvantages of wave energy. ... What are the disadvantages of using wave power? None of this is to say that wave energy cannot be useful, but those interested in using it to create power have to look at both sides of the equation. Because wave energy is still in its infancy, mostly in research, there is no measure of the environmental effects of large-scale power stations on the shore. In a longitudinal wave, the medium movement is parallel to the wave direction. The effects of this are global warming and climatic changes. As we mentioned this a couple of times before wave energy is a renewable source of energy, which means that we will never run out of it. Explaining The Ocean wave energy conversion in this article alone is not possible. For this reason, the need for green energy will increase. Only power plants and towns near the ocean will benefit directly from it. This turbine is attached to a generator that creates the electricity. So what type of waves do these winds form? The performance of wave power drops significantly during rough weather. Concerning being environment-friendly, we can learn that wave energy is even more beneficial to land impact. It is a highly accessible for of energy for most coastal nations. Cons about tidal wave energy. Disadvantages of Wave Energy. But How. Advantages of Wave Energy Disadvantages of Wave Energy 1. The force of the air being pushed is used to turn a turbine. Let’s take a look. Wave energy boasts many advantages such as its low cost, zero to no pollution, and a large energy output. Disadvantages of Wave Energy 1 Cost Because harnessing energy from wave power is in its relative infancy, speculation on costs is not easy in comparison to the likes of solar- or wind-garnered energy. 15 Main Advantages and Disadvantages of Biomass Energy, The Real Importance Of Green Revolution | Definition, Benefits, Issues. Wave energy is strong winds which act in the oceans. The energy from waves can be taken directly into electricity-producing machinery and used to power generators and power plants nearby. Yes, Solar Panels Work In The Rain! Unlike ethanol, a corn product, waves are not limited by a season. Above all, the wave energy is efficient. Don’t we all want electrical power production that does not affect our environment? There is also a danger of toxic chemicals that are used on wave energy platforms spilling and polluting the water near them. Huge Amounts of Energy can be Produced, 5 Practical Improvements to Reduce Your Company’s Carbon Footprint, 3. Disadvantage of location The downside to wave energy is the location. Since it is also renewable, we do not have to worry over the source becoming extinct. Not only will it help to curb air pollution, but it can also provide green jobs to millions of people. One of the best features of wave energy is that it is a renewable form of energy. They are what enables us to generate wave power. Advantages and Disadvantages of Wave Energy. Wave energy is also a type of renewable energy and is the largest estimated global resource form of ocean energy. The only possible problem with offshore power plants is that they are very expensive.
