It is estimated that the potential of the energy generated by the waves of the sea at world level is of at least 2 Tera Watts. 4. 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. Using Tides for Generating Power. Conventional fossil fuels contribute to air pollution, whereas tidal power leaves no by-products. This source of energy is got from the waves and tides and hence there is no requirement of any payment for incurring such energy. Two common examples of this type of energy are solar power and wind power. It does not require any fuel. 2) Tidal energy is environment friendly energy and doesn’t produce greenhouse gases. It is only active for about 10 hours a day. Currently, tidal energy is still in the early development stages, not being able to compete with fossil fuels. In order for a tidal power plant to be built, the potential installation site must meet very specific requirements. 2. That is why some rivers are not suitable as a power generation resource. Despite being cost-effective, tidal energy hasn’t yet become a popular choice. In order to ensure that we are … Tidal energy is considered as a type of renewable energy source because we do not consume the tides in generating power from them. Tidal energy is extremely efficient. 4. List of the Advantages of Wave Energy and Power . Being built to work in such a harsh environment, the tidal turbines used by a tidal power station will work for a very long period of time (over 50 years long). 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. The tidal cycles in our oceans are produced by the gravitational forces of the Moon, the Sun and the Earth combined, and can be used as a renewable resource of clean energy that can reduce our dependence on fossil fuels. Environmental effects and disruptions to the tidal flow; The primary form of tidal power plant that exists today is the barrage, a dam built across estuaries. It is renewable. Tidal energy is formed due to the flow of water which is a natural phenomenon. Roughly 80% of total tidal energy is harnessed, collected, stored and distributed. This process has a number of advantages and disadvantages associated with it. 4. Disadvantages: The tides are not constant so energetic production may not be reliable. Advantages and Disadvantages of Tidal Power 3. Is A Predictable Source Of Energy. So far, there is no reason to believe that tidal energy plants are not long lived. Disadvantages It has been difficult to scale up the designs for wave machines to produce large amounts of electricity. When tidal energy facilities first come online, the environment works to adapt to the changing circumstances. Tidal energy is known as a green energy source as it is environmentally friendly as it does not pollute the environment by emitting harmful climate gases. A tidal power station works using flowing seawater which has a much greater density (compared to the density of the air used by wind turbines).eval(ez_write_tag([[468,60],'alternative_energies_net-leader-3','ezslot_21',118,'0','0'])); Working in such hard conditions, the tidal turbine needs to be very robust, and at the same time needs to protect marine life (fishes and other marine creatures will use an escaping corridor located in the center of the turbine to get away from the rotating turbine. Energy; About; Contact; Select Page. We must require a proper site, where the tides and tidal currents are consistently strong. One of the advantages of using tidal energy is that it is a renewable source meaning that it will be around to use for a very long time before having to worry about this … Tidal energy is part of the renewable energy sources that will dominate the future. True effects of tidal barrages on marine environments have not been fully explored yet. There are additional requirements a potential site must meet. Tidal power is an alternative energy source that will replace the fossil fuels in the future, but it is also a renewable energy source because tidal cycles are produced every day by the gravitational forces of the Moon, the Sun and the Earth combined.eval(ez_write_tag([[300,250],'alternative_energies_net-leader-1','ezslot_8',116,'0','0'])); Being a renewable energy source it means that tidal power will be available for producing clean electricity as long as we live here on the planet. It should be close to land. The tides cannot be ‘used up’. So, there is a little … 1. It is not cost-effective. Tidal barrages destroy the habitats of estuary species, including wading birds. Today, the capacity to produce tidal power is limited because tidal power stations require that the tides to be pretty high (low tide needs to be at least 5 meters tall).eval(ez_write_tag([[336,280],'alternative_energies_net-large-mobile-banner-2','ezslot_6',117,'0','0'])); However, the technology evolves pretty fast, and in a not so far future from now on, we will be capable of producing tidal energy in almost all coastal areas of the planet, even where the tides are not very high.
