![]() Small dams and barrages, which are used to harness tidal energy, could protect ship ports and coastal areas from the dangerous tides during storms and bad weather conditions.ġ. It reduces foreign importation of fuel.īy harnessing tidal energy on a large scale, we can help reduce foreign fuels importation and enhance energy security, as people would no longer have to rely much on foreign fuel import to satisfy the growing energy demand. As an example, the La Rance tidal barrage power plant was constructed in 1966 and is still generating large amounts of electricity up to this day.Ħ. This means an ultimate reduction of the money spent on selling the electricity, making this energy source a very cost-competitive one. So far, there is no reason to believe that tidal energy plants are not long lived. Based on calculations, power can be generated even at 1 minute per second, which is equivalent to a little over 3 feet per second. Water is a thousand more dense than air, which makes it possible to produce electricity at low speeds. This is why both the equipment’s installed capacity and physical size have entirely other limitations, though tidal turbines and stream generators that are being used are very similar to wind turbines. Sea currents are highly predictable, developing with well-known cycles, which makes it easier to construct tidal energy systems with the correct dimensions, since the kind of power the equipment will be exposed to is already known. ![]() Important studies and assessments are being conducted on these things. However, there are already some examples of tidal power plants and their effects on the environment. Compared to nuclear reserves and fossil fuels, the sun and moon’s gravitational fields, as well as the Earth’s rotation around its axis, will not cease to exist any time soon.Īside from being renewable, tidal energy is also an environmentally friendly energy source because it does not take up a lot of space and does not emit any greenhouse gases. With this in mind, the power source of tidal energy is potentially renewable, whether we are talking about tidal barrages, stream generators or the more recent technology, dynamic tidal power (DTP). 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. In order to completely understand its significance and effects, it would help to gain a clearer understanding of these opposing aspects. ![]() Tidal energy is already offering many advantages, but put in mind that it is also linked to some disadvantages. However, the focus on renewable energy sources and the demand for clean energy are contributing to a rapid development of methodologies to harness this type of energy source. Though it is not widely used, it serves as a significant investment when it comes to electricity generation.Ĭurrently, tidal energy is still in the early development stages, not being able to compete with fossil fuels. Tidal energy pertains to a form of power that particularly transforms the efficiency of the tides to beneficial forms of dynamism. ![]()
