Energy Resources: tidal energy! By: Gul-e-Rana’a, and Jaweria Class: 7A~Girls. What Is Tidal Energy? Tidal Energy is a form of hydro-power that exploits the movement of water-waves caused by the rise and fall in the sea level due to tides(waves) Categories Of Tidal Power Tidal Flow: Make use of Kinetic energy from moving water current to power turbines Tidal Barrage Power: Make use of Potential Energy from the difference In height(or head) between high and low tides. Advantages Of Tidal Power Tidal energy has high reliability, excellent energy density, and high durability. Because the Earth's tides are ultimately due to gravitational interaction with the Moon and Sun and the Earth's rotation, Tidal power is inexhaustible. Disadvantages Of The Tidal Power Placing turbines in tidal streams is complex, because the machines are large and disrupt the tide they are trying to harness. The environmental impact could be severe, depending on the size of the turbine and the site of the tidal stream. Is Tidal Energy Good FoR Pakistan? Tidal power is 80% more efficient compared to coal and oil. Harnessing the power of high-energy waves, the shoreline will be protected from sediment erosion. More energy can be produced from tides along the coast of Pakistan. Tides are renewable and active 24/7, 365 days which is very good for Pakistan. Advantages For Pakistan The country can control its energy crisis by generating fuel-free and low-cost Tidal power. Pakistan has a 1,045-kilometre coastline, which is ideal for producing tidal energy due to its favorable characteristics. Ocean tidal resources are denser and more reliable than others for generating power at a low cost. DisadvanTages For Pakistan It is expensive for Pakistan. The turbines can impact the surrounding ecosystem. The power produced does not always match up with peak energy demand. Conclusion Tidal Energy can be focused as an alternate energy source of Pakistan. It’s environmental impacts of Tidal process is much more smaler than using conventional fuels such as fossil fuels and nuclear plants. Though Tidal Power cannot alone fulfill complete demand, however can be helpful to overcome the problem of shortage. Thankyou Very Much For Your Time!
