What are waves? Ocean waves are caused by the wind as it blows across the sea. In many areas of the world, the wind blows with enough consistency and force to provide continuous waves. It contains both kinetic and potential energies. The kinetic energy is related to the velocity of the movement of water, and the potential energy is a function of the amount of water displaced from the mean sea level. They are a powerful source of energy, it’s renewable, environment friendly, abundant and widely available. However the problem is that wave energy is only suitable to certain locations, and it also effects on marine ecosystem.
The best thing about wave energy is that it will never run out. Its a renewable energy source, because the waves flow

The energy from waves can be taken directly into electricity-producing machinery and used to power generators and power plants nearby making “clean energy”. Which are hard to find these days. Another benefit to using this energy is its nearness to places that can use it. Lots of big cities and harbors are next to the ocean and can harness the power of the waves for their use. About 40 percent of the world’s energy is produced by the “waves”. Coastal cities tend to be well-populated, so lots of people can get use from wave energy plants. A final benefit is that there are a variety of ways to gather it. The biggest advantages of wave power as against most of the other alternative energy sources is that it is easily predictable and can be used …show more content…
It has its drawbacks as well. 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. Because of its source, wave energy is not a viable power source for everyone. 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. As clean as wave energy is, it still creates hazards for some of the creatures near it. The large machines that are in the water disturb the seafloor, change the habitat of near-shore creatures (like crabs and starfish) and create noise that effects the rain . There is also a danger of toxic chemicals that are used on wave energy platforms spilling and polluting the marine ecosystem around them. Another downside is that it disturbs commercial and private vessels. Power plants that gather wave energy have to be placed by the coastline to do their job, and they have to be near cities and other populated areas to be of much use to anybody. But these are places that are major thoroughfares for cargo ships, cruise ships, recreational and etc. All of these people and vessels will be disrupted by the noise and visual pollution of a wave energy gathering source. 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
A storm surge is the rising of the sea as a result of atmospheric pressure changes and wind associated with a storm. Storm surges usually result in flooding in
Cape cod has an interesting back story filled with slow moving glaciers. The sandy formation juts out into the Atlantic Ocean and is home to fascinating creatures year round. However the landform its self is far more interesting. From immense sand formations to unique current and tide movement, the oceanic spaces are captivating. The pressure of the open Atlantic with the added pressure above from the ever changing gulf of Maine create a diverse set up of bits and ends of curious patterns.
The waves it produces- the large, freak waves in particular- attract surfers and scientists from all across the globe who indulge in the entertainment they produce and the chance to study their patterns. In her book, The Wave: In Pursuit of the Rogues, Freaks, and Giants of the Ocean, Susan Casey follows surfers from all parts of the world and interviews world-renowned scientists to study the ocean’s inner-workings and what makes it so appealing to such a wide array
Science A tsunami happens when tectonic plates converge after earthquakes, landslides on the seafloor, large volcanic eruptions, or a meteorite crash on the ocean floor. In this case, the tsunami was caused by an earthquake. When the earth’s tectonic plates move and grind against each other, energy builds up. There are three phases to a tsunami: the generation, the propagation, and
“Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers” ( Megan Forbes, 1). Odysseus has obtained Poseidon’s wrath, and number one rule is to not
Very rarely do waves ever stop. It’s also renewable, and that’s important. Waves don’t stop, and if fossil fuels become all used up, we can always use wave energy! With other alternative energies, you can’t always use it all day, like solar energy, which needs sunlight to work. Waves won’t stop until seven billion years from now when the sun burns out.
• Wave refractions cause waves to crash persistently away at the base of headlands and can result in wave-cut cliffs after extensive undercutting (Trujillo and Thurman, 2017). If the wave-cut cliff has yet to crumble due to gravity, it can result in sea caves or sea arches (Coastlines). For example, there is a sea cave in Cabo San Lucas and a sea arch in Western Australia (Coastlines). • Marine pollution is created by humans who have introduced anything that is harmful to the marine environment, the living organisms of the ocean, and the organisms that use anything from the ocean resources (Trujillo and Thurman, 2017). Harmful substances that pollute the ocean are detergent, antifreeze, pesticides, plastics, discarded fishing nets, and much
A tsunami is a series of great sea waves caused by an underwater earthquake, landslide or volcanic eruption. A tsunami is a series of many waves known as wave trains. A tsunami can also be generated by a giant meteor. Most tsunamis are known to be formed by underwater earthquakes.
It uses flowing water to generate electricity. It does this by using dams and reservoirs for storage. This method gives us the most electricity rather than any other renewable energy source. Not only do the dams and reservoirs create electricity, they also control flooding (Sambu). Hydropower is the least expensive procedure to generate electricity.
Nuclear energy only creates minimal negative effects to the environment. Nuclear energy produces steam and low levels of carbon dioxide. Nuclear energy is also beneficial seeing that it produces a large amount of energy for a low cost. Nuclear reactors generate energy at a lower cost than oil, gas or coal. This nuclear energy will be a stable source of energy seeing that it is a base load source and it is synergistic with other renewable resources.
Very large amounts of electricity can be generated in one place using coal, fairly cheaply. Transporting oil and gas to the power stations is easy. Gas-fired power stations are very efficient. A fossil-fuelled power station can be built almost anywhere o Disadvantages of Using Fossil Fuels Basically, the main drawback of fossil fuels is pollution.
Nuclear power is a bad idea because it is not environmentally safe. These nuclear power plants are also a lot more expensive, there are cheaper ways. Nuclear power could cause a massive amount of deaths if not done right or under control. One reason is the Nuclear power activities that are involving the environment; mining, enrichment and generation.
For many years now, it has been debated which of the new and upcoming renewable and sustainable energy sources if the best to use. Energy create from wind, is a very favourable contented in this debate as it is a very good alternative energy source. Wind energy is used all around the world. Humanity has been using wind energy for over 100 years. For example, we used to (some still do) use the wind energy to grind grain in old fashioned wind mills..
Non- fossil fuel energy has a lot of trouble producing the amount that fossil fuels can produce. This means we need to cut down on the amount of energy we use or just build a lot more production facilities. Another downside is that renewable energy relies on weather 90 percent of the time. If there isn 't rain to fill the dam the Hydro generators can 't run. If there isn 't wind for the wind turbines it wont go.
Energy is simply the capacity to do work. Energy has become one of the necessities of our modern life. Energy can have many forms like heat, electrical, chemical, nuclear, light, etc. In the pre historic era fuel wood was the major sources of energy. Conventional energy sources are the ones that have been using so far to fulfill most f our daily energy requirements of cooking, lighting, transportation etc.
