Efficiency of Tidal Energy in the UK

“Tidal power generates energy from the tides moving in and out…wave power generates energy from the rise and fall of waves.” (Cunningham.) Capturing the ocean’s movement is a great form of renewable energy with waves never running out and that they are available in many areas of the world. There will be no byproducts that will be harmful or will pollute the environment, and to receive the energy there can be many different gathering techniques. In retrospect towards marine growth, submerged wave energy converters will make “safe havens” because they will become artificial reefs with a closed off surface areas. “They insist that if all 28,000 miles of U. S. roadways are covered in these solar cells, it would generate three times more power…” (Cunningham). The hexagonal solar panels would be able to make more productive areas such as a solar parking lot, additionally paying for themselves and power other homes or businesses. In order to improve the safety of every community, there would be heating elements to keep roads snow/ice free, and LEDs to make road lines. There is little maintenance to ensure that the solar panels are in working order, and they are a silent producer of energy. When compared to burning fossil fuels in power stations, solar energy stands out by the fact that it saves money and gives energy security in households. “Human waste is taken to a treatment plant…methanogens go to work…methane is produced as a byproduct.” (Cunningham). Currently, over 200 millions tons of human waste go untreated, and once they get into the clean water, many die from diseases in contact with the fecal matter. When methane is burned as electricity, there would be a decrease in treating water and disposing

Coastal areas in Canada are able generate approximately 37,000 MW (megawatts) or more electricity annually. They are able to do this by harvesting the tidal waves and using devices such as tidal turbines,tidal barrages or tidal fences. These are a variety of methods which allow us to utilize this renewable form of energy with efficiency. Coastal areas harnesses energy when a tidal current or an ocean wave has a vertical or horizontal motion that occurs on one of the tidal devices, which are turbines that can spin. As the turbine spins it produces energy into a generator that's attached to itself, and then the generator converts most of the energy into electricity.The potential gravitational energy caused by the moon, sun and rotation of the earth allow tides to be more frequent and harness a greater amount of energy. This gravitational energy also causes low tides or high tides to occur, which influences the rate in which the water flows into the turbine.

This is why tidal energy generation would be much more efficient than hydroelectricity energy generation in Nova Scotia because there are not many strong flowing rivers. The Electric Power Research Institute (EPRI) located in California stated that the Bay of Fundy had potential to be the best site in North America for tidal energy generation. I believe that Nova Scotia should take advantage of these tides and use them as an important resource for our province. After the costs of the infrastructure and maintenance, tidal energy generation would be essentially free, as the tides move on their own. A lot of energy can be created through tides, as tidal power is very sensitive to speed. The amount of energy formed is the cube of the speed of the water. For example, if the speed of the flowing water doubles, the energy output is eight times greater. This energy can be formed from both the change in the height of tides, which is potential energy, and the flow of the water, which is kinetic energy.. As of now, the main technologies used are in-stream devices, barrages, and tidal lagoons. I think the best solution for Nova Scotia right now would be to build a tidal lagoon in the bay of Fundy. A tidal lagoon is like a barrage (which is essentially a dam built across the whole estuary) but it can be built as a self contained structure. This makes the cost much lower and they can also continuously generate, unlike a

In today's world, to get to anywhere or do anything, we are more than likely burning fossil fuels in some manner. Although fossil fuels are a viable form of energy, they are a finite source. An alternative, infinite source is renewable energy, exists in a multitude of forms and with an abundant amount of benefits, one of which including the low impact on the environment. A practical example of renewable energy is wave energy. Surface waves contain an abundant amount of kinetic energy that can be harvested and directed in the use of tasks such as producing electricity and desalination of water. According to Eugen Rusu in Renewable Energy, wave energy offers high energy density which allows for more energy to be extracted using

6a. Discuss the pros and cons of alternative energy as a viable alternative to traditional energy generation on the Western coast of Scotland

Waves are produced by winds blowing across the surface of the ocean. However, because waves travel across the ocean, their arrival time at the wave power facility may be more predictable than the wind.In contrast, tidal energy is driven by the gravitational pull of the moon and sun. Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity. Tidal power has great potential for future power and electricity generation because of the massive size of the ocean [29][30].Tidal power has a relative advantage in that it can generate power from

First of all, the author of the reading passage states that wave firms are able to generate powers constantly because coastal areas generally experience the same seasonal variations in wave, so it is possible to predict the generation capacity. However, the lecturer contradicts this point by arguing that wave-energy facilities are new, so there are high possibilities to occur thecnical trables. These trables will disrupt the energy generation.

Tides and currents have existed since before the dawn of man. While the rotation and gravitational forces of the earth act to keep our ocean levels steady, that equilibrium is disrupted by the moon and the sun. The gravitational pull of both the sun and the moon cause the oceans to bulge, and as this bulge moves around the planet, the tides occur. Furthermore, the moon, although significantly smaller than the sun, has a far greater affect on the tides due to its relatively small distance from the earth. In addition, the tides also vary in intensity based on the alignment of the sun, the moon, and the earth. When aligned, a higher than normal, lunar high tide occurs. But why are these flows relevant to renewable energy? They are important because that tidal energy can be harnessed for use as a power source. Tidal power, like other renewable energy sources, is inexhaustible. In addition, there is a major advantage over other clean energies, in that tidal energy is very predictable. For example, there are not any wind charts telling what time of day the winds will be optimal but there are charts of the tides. Therefore, by taking advantage of this resource, your community could work towards being energy independent and self-sustaining. Moreover, there could be an opportunity to use any excess power generated as an income source.

Using wind turbines has helped put the UK on track to achieve deriving 20% of its energy needs from renewable sources

First of all, renewable energy is essential to Elbawener 's future economic growth and prosperity in a carbon-constrained world. (Introduction of Renewable energy, CEFC, 2015) This is really a perfect thing for Elbawener. What’s more, renewable energy would help lower Elbawener 's and Australia 's carbon emissions, this is really good for the environment of

With this huge demand of electricity within the UK it 's hardly surprising that the UK between 2007 and 2012, has had a peak electrical demand 52.5 GW. To put that in perspective that 's 52500000000W!

This chapter will examine the available literature on policies used to encourage the growth of renewable energy sources and technologies. A wide variety of policies have been introduced around the world with differing levels of success. This chapter will look at some of them and discuss whether Scotland should adopt, intensify or even abandon each one.

This paper strives to shed light on the advantages of s-scale renewable energy technologies, specifically five of those technologies, small hydroelectric, geothermal, anaerobic digestion, small CHP, tidal energy. While there are many more, this paper focuses specifically on the five by now which matured and have already been somewhat implemented, and are innovative. These are renewable energy whose plant capacity is typically (can typically produce) under 50MW, most often up to 10MW. The paper then strives to look at each

With companies becoming more aware of how important it is to reduce their current environmental impact, alternative energy sources like solar and wind powered energy are becoming more prominent as eco-friendly alternatives to current unsustainable methods of power such as fossil fuels (BBC, n.d.)

Hydroelectricity is power derived from the energy of failing water which can be harnessed and used. Since water is about 800 times denser than air, even a slow flowing stream of water, can yield considerable amounts of energy. Once a hydro power plant is constructed, the project produces no direct waste. However, the number of water sources limits the development of hydroelectric power stations, which is why underwater tide turbines within the oceans may be another great alternative power source to harness power from the natural flow of water.
